Looking to build in the Lianli o11mini, is 240mm AIO like Galahad or h100 enough to cool ?

it will if you can live with higher temps. the case can fit larger, and i would recommend at least a 280mm. there are several threads on aios and the 12 series you could look at. you can also play with "under volting" to help keep temps down. the 12 series are just hot chips.

280 mm rad is way better than 240 mm rad, but not quite as good as 360 mm rad .. and bigger rads run quieter at same temp.
280 mm rad is 392 sq cm surface area and 360 mm rad is 432 sq cm.
By comparison 240mm rad is only 288 sq cm surface area.
The bigger the radiator the more heat it can transfer from water to airflow. 280 rad is 1.36 times bigger than 240, 360 rad is 1.5 times bigger than 240. Sure 360 is little bigger, but both 280 and 360 are significantly more cooling than 240.

I think Tech Jesus did some videos about it last year. His take was there are only 3 new AIOs that aren't rebranded Asetek designs. The EK AIO, the Lian-Li Gallahad, and the Arctic Cooling Liquid Freezer II and all of them should out perform Asetek designs for various reasons.

As long as the Lian Li has good mounting pressure, it should be fine. From what I've seen, the older Asetek design wasn't mounting as well with ADL.

There are a few others. Swiftech and Alphacool both market their own All In One coolers. Theirs have treaded fittings on all components, copper radiators, etc.

Swiftech line is Drive X3.
http://site.swiftech.com/

Alphacool lines are Eisbaer, Eisbaer Extreme, Alphacool Eiswolf, etc.
https://www.alphacool.com/products/

Yeah, both of those are expandable though IIRC. I think Tech Jesus was talking about more traditional "CLC" versions as you like to call them.

Indeed! But even more important is they have much better pumps flowing twice or more as much coolant.

"Expandable" means if something goes bad (pump is most common component to go bad in liquid cooling) it can easily be replaced instead of throwing away and having to buy a complete new system.

It also means coolant can be topped up as levels go down, and also drained, flushed and re-filled with new coolant every couple of years.

Great ideas except honestly most consumers just spend the $120 on a AIO and use it for the 5 years it is warrantied. CLC AIO's are generally reliable and if you stick to the brands with a 5+ year warranty, you will be fine. Expandability is a great idea, except these AIO expandable systems are not nearly as nice as a dedicated loop with a D5 etc.In other words you won't be doing much expansion without taking a hit on performance. At least in my experience.

As much as I enjoyed water cooling as a hobby, these CLC AIO's have come a long way and are top notch reliable now. I have friends running AIO CLC's from corsair from 2016. and they still are doing their job. And even if one broke, thats 5 years for the price of just FITTINGS on any high end water cooling setup.

Not to mention the "add on" for a GPU seemed like it was pretty expensive. Other than that, I'm not sure how many changes you'd make without just building your own loop.

Most consumers are sheep. ;) They believe almost everything they hear / read. "5 year warrantee" is often a lot of sales hype as well. Sure it is a 5 year warrantee, but it often takes more time and money than it's worth to get replacement. True, expandable is not the reason to buy one. While they do have more powerful pumps, they are still not near as goodd as D5 pump.

While there have been improvements in CLCs, those improvements are quite limited. Most CLCs have pumps with no published specs, but independent testing has shown most to flow 40-60L/h. That is about the same rate most healthy young adult males urinate, even after a few beers.

From experience 90-120L/h is enough for most cooling jobs. To cool CPU and GPU more is better. Lower flowrates show much slower heat removal / higher temps with rates up to about 200L/h giving even better cooling. Higher flowrate show less and less improvement up to about 300L/h and almost no improvement above that.

But having a easily accessible fill port so user can keep coolant topped up is important. Even more important on these cheap CLCs and low cost AIOs because they have very little reserve coolant. Problem is few have fill ports, and those that do are not placed where it's easy to add coolant.

I agree, custom water cooling in quite expensive. Most of the CLCs more than a few years old are not cooling hi-heat components. I don't look at is "5 years for price of fittings" but 5 years for price of top tier air cooling that will last longer than all but a very few will ever use them. Last time I priced components, or the price of 2 CLCs users can buy a repairable expandable water cooled system.

Corsair hasn't used Asetek for two AIO lines, now.

240mm is fine for a stock 12700k.

If you are overclocking, it could get pretty warm with an all core, 100% load, such as Cinibench R23. But, should still keep it from throttling. And in games and most programs, it will be totally adequate.

The Lian-Li Galahad needs to lose some height on the CPU block. It is unecessarily tall.

I went with a h150i elite because of that. And yes Corsair has not used Asetek for generations now.

A 240 would be fine but a 280 would be ideal. 360 if you have the room.

What do they use now? CoolIT I would imagine. I think I have a H100x which was a CoolIT designed bargain basement water cooler that does OK with decent fans.

I haven't seen the Gallahad in person. Reminds me of a Deepcool Captain EX though. Very tall...not much reason for it. The EK AIO seems to do ok for me so far. I would recommend as long as the weird tube outlet fits your build.

Alphacool Eisbaer Extreme is an exception here though as it is essentially a pre-built custom loop with D5 pump and XPX waterblock. It is only a 280 radiator though and low noise fans so limited max cooling capability unless you expand it.

A 240 AIO would be adequate, but a 280 that is side mounted would be ideal for CPU temps and should be supported by the case. As long as you run your GPU on air it will heat up the case air significantly. A 200w card can increase the case temps 4-5 degrees while a 350w card can increase the temps 8-10 degrees with good airflow so letting the radiator draw fresh air is optimal for CPU temps. Drawback is that the case temps get a few degrees higher. A 240 will most likely offer similar cooling performance to the high end air coolers, while a good 280 AIO can be a few degrees cooler at moderate noise levels and also gives the option of lowering noise levels with the same cooling performance as a 240.

Can you please tell us which Corsair branded CLCs are not Asetek OEM and what OEM they are?

If that's the only problem it's hardly worth talking about. Galahad pump waterblock unit is only 2.5" / 63.5mm tall.

I think Alphacool Eisbaer use use Eisbaer Solo pump which measures 63 x 63 x 68mm (WxDxH). Thats taller than Galahad. ;) Not sure which one it is, but it's rated either 72 L/h 1m lift or 120 L/h or 2m lift. The lower is much better flowrate and lift than normal CLCs and if higher spec it's more than 3 times that of almost all CLCs.

I have a list compiled a few years ago of as much data on AIOs/CLCs I could find showing what OEM the were and what their specs were that I could post.

The newest line, Elite Capellix. And the previous line, RGB Pro XT. Both are not Asetek. They are made by Coolit. Corsair actually used them previously, until Asetek won their patents, which prevented some AIO designs from being sold. So Corsair used only Asetek, for a couple of lines. Then they completely dropped Asetek and have only used Coolit, once they came up with a design which does not violate the patents. This first Coolit based line was the RGB Platinum.

Maybe its an optical illusion. But the Galahad seems taller than even the EK AIO block.

the square ones are not asetek but idk who makes them. anything round, is asetek.
you gotta look at the copper plates. round plate or squared. Because Corsair made a couple of asetek models (round copper plate) with square shape on the block, similar to even the newest stuff.

I just wanted to clarify. Because, the recent design of the cap on their pump block, is a sort of square shape. but they debuted that square shaped block design---on top of an Asetek design, with a roudn copper plate underneath. When before----the whole thing was just a round Asetek OEM block design. Much like Phanteks still are.

Looking to build in the Lianli o11mini, is 240mm AIO like Galahad or h100 enough to cool ?
Someone on the OcUK forums recently took off their Dark Rock as it had mounting issues and used a Noctua air cooler they had which fit perfectly. Temps were 30 idle and 70s running Cinebench. So a single or smaller AIO cooler is definitely capable of cooling a 12700K. Use good quality paste like stuff from Thermal Grizzly and you're good to go.

I have a 280mm Arctic Freezer 2 on my 12700KF and idle/normal use temps are 27 with gaming loads in the 50s whilst CInebench pushes it to mid 70s.
I saw on some reviews they mention the Corsair AIO backplates don't cover the whole length of the IHS so might be worth looking into that. I noticed no coverage issue with Arctic though.

Are you talking about the copper cold plate which contacts the IHS?

Yep that's the one! I saw it talked about on reddit but don't know exactly which models that applied to at the time as I had already ordered the Arctic Freezer II.

Ah. So that would have been for the old Corsair AIOs made by Asetek, with small, round copper cold plates. The newer models made by Coolit, have large, squared copper cold plates. If I'm not mistaken, they are actually adequate for Threadripper. But even if they aren't.....I can tell you a 12700k has no problem fitting under my Corsair H115i RGB Pro XT. Plenty of extra space.

I can say for certain the Corsair h150i elite block entirely covers the 12700k. I’ve re mounted it, which is how I confirmed. Covers it and then some.

This is the newest square shaped pump setup, with OEM by CoolIT.

[Discussion] A word of warning about Corsair CLC​

renderTimingPixel.png


Discussion
Corsair released new versions of their popular closed loop coolers, the GTX series. They are successors of the GT series. While they tout small improvements, they fail to mention that the new series is made by a new manufacturer and comes with severely crippled firmware. For example, the H100i GT was made by CoolIT, while the newer H100i GTX is made by Asetek. This explains why this is happening. Edit: From the link
"Asetek is a CLC supplier, sourced by the likes of Corsair and NZXT for many of their CLC products. CoolIT, also a supplier, may be required to limit sales of its units to companies implementing its solutions in manufacturing. We are yet unsure of the full extent of the settlement."
This is a short list of differences I copy pasted from a Corsair forum post:
  1. CoolIT H110i + H110iGT have two and H100i + H80i have four fan controllers, all Asetek only have one.
  2. CoolIT can use any temperature source, Asetek can only use the Cooler Temperature.
  3. CoolIT firmware can be updated, Asetek can't
  4. CoolIT lights have far more functionality than the Asetek .
  5. CoolIT reports the pump speed to CPU_FAN, Asetek reports a fan speed.
  6. CoolIT use the standard Microsoft HID Device Driver, Asetek need a special Device Driver.
The biggest problem for me is #2. Basically, the Asetek cooler can only use the coolant temperature for controlling the CPU fan curve, which makes it completely fucking useless. My coolant temp hovers around 35-40C while my CPU is pushing 95C. THERE IS NO WAY TO SWITCH THE SOURCE FROM COOLANT TEMP TO CPU TEMP WHICH IS AVAILABLE ON THE OLDER CoolIT H100i GT. The fan curve is absolutely useless. It can only respond to coolant temp, nothing else. You can't change it. My CPU is burning up and the fans are chugging along at idle speed because 35C coolant temp. It's completely beyond me how something like this made it to production. Serious oversight from everyone involved, especially since the older versions didn't have this problem.
As someone who has religiously bought Corsair products, I am very disappointed by this. A supposedly improved, newer, more expensive product which comes with less functionality than its predecessor is a great way to turn people away from your brand.
With that being said, can anyone recommend another software to set a custom fan curve which will override the bullshit Corsair link fan curve?
EDIT: It appears that Corsair have changed the names of these coolers recently. The new names are simply H100i and the H100i V2. They used to be known as the GT and GTX respectively. Don't be a sucker and fall for "newer is better". In this case it's not.
Double Edit: It appears that the V2 may or may not be affected by this (thanks to /u/Why_Run for pointing this out that his V2 was working fine under W10). The V2 was confirmed to be just a rename and still uses the Asetek hardware. Here is what a Corsair employee had to say when asked:
"The Asetek hardware is...silly. I can't say more than that. But the controller in it is significantly weaker than the one in the CoolIT-based H110i GT."
and when asked if they would be implementing a software solution
"I wish I could tell you. There are some astonishing limitations to the Asetek hardware."
One Final Edit: So far this appears to plague only the GTX series. Sample size is small but 2/2 people are able to change the source of the temp under Windows 10. Take that for what it's worth. Otherwise, the V2 appears to be an identical unit to the GTX, simply renamed. Corsair have stopped selling the GTX from their website, Amazon only has it from the marketplace, meanwhile Newegg is still selling it. You should avoid buying the GTX.
Finally, I'm saddened that Corsair chose to an inferior product that was clearly marketed as something supposedly newer and improved. There was no disclosure that the GTX was missing a key feature which was available on its predecessor. I certainly feel like I got played since I spent extra to get the GTX instead of the GT when it came out.
TLDR: If you are buying a Corsair closed loop cooler, avoid the GTX series. The older GT series is cheaper and offers more functionality. They are made by different manufacturers.

What are you all talking about? Take a look at this, from Corsair link H100i V2. I can easily set this sucker to punch it with all fans to make a custom curve based on CPU temp. It's obnoxiously loud though.

What am I missing?
Edit: Was using CPU-Z to "stress" CPU to cause temp increase and trigger fan profile.

Interesting. What version of Corsair Link are you running and OS?
This is mine for comparison. There is no way to change the source of the temp for me.
edit: why would you downvote me for sharing information?


As far as I know Corsiar makes nothing .. nothing is Corsair OEM. They contract with other companies to develop and manufacture products they want to market. These other companies then develop it, present it to Corsair for opproval, and after approval manufacture and package complete with Corsair brand name on it. Not a bad thing because most brand names do this. That said, as far as I know Corsair does very little if any of their own R&D (research & development) themselves. Other companies develop product to meet Corsair criteria. Again, something many companies do.

Indeed! But even more important is they have much better pumps flowing twice or more as much coolant.

"Expandable" means if something goes bad (pump is most common component to go bad in liquid cooling) it can easily be replaced instead of throwing away and having to buy a complete new system.

It also means coolant can be topped up as levels go down, and also drained, flushed and re-filled with new coolant every couple of years.
any tests done on the difference of pump flow within reason? cause on my loop the speed doesn't affect temps as much. (i am not on a Alderlake btw just talking about pump speed)

I've seen data showing way better cooling as flowrate increases from 50L/h up to about 120L/h, starting to round off between 120L/h and 200L/h, then showing little improvement on up to 500-600L/h limit of D5 pumps. We need to keep in mind waterblock and radiator effects as well. I think it's fair to say pumps with flow rates up to 50-60L/h are marginal at best, flow rates up to 100L/h are decent, and flowrates up to 200L/h range are optimal for most applications. Keep in mind the most popular custom loop pump is D5 ( with 1500-1800L/h rating @ 4800rpm with most users running their pumps up to about 2500rpm .. maybe a little more. I haven't used a custom loop in too many years to be sure anymore. ;)

Koolance says
"Flow rate tends to be over-emphasized in PC cooling. For the majority of loops, effective flow rates higher than 1.5-2.0 LPM (0.4-0.5 GPM) won't contribute much, if anything, to thermal performance."\
1,5-2.0LPM is 90-120L/h

Most CLCs have pumps flowing significantly less than that.

I added ID-Cooling CLC specs to my post of data (post #31). If anyone knows of any other CLC specs, please post linke to them so I can add them to above data.

I have this Corsair H150i for my i7-12700k build. Figured I'd go all in this time. It's been almost 4 years since my current build.

Maybe because my loop has 840mm of alphacool copper? I think I'm running about 20-30% on the ekd5 pump and when I push to above 50-60% i don't see much difference. Is it cause I have plenty of thermal headroom? 6900k 16 thread & 3080Tiftwultra.

840mm of rad obviously helps. Assume you mean EK-D5 pump, so 20-30% would be 300-400L/h cooling 2 components. I'm assuming you don't have a flow meter in system? This means we are guessing at flow rate based on percent of speed, and it's quite possible with that much rad and 2 waterblocks all adding resistance to flow rate that your actual flow rate is less than 20-30% .. like maybe 150-200L/h. Also 2 components are about twice as much heat into coolant so higher flow rate moving more coolant keeps coolant temp lower so it can absorb more heat and keep components cooler as well.

Yea bro I worry about it sometimes because there is a 360 in the front & a 360 on the roof & another 120 on the rear all the same model 30mm alphacool copper. Going through 3 rads and 2 blocks up & down & around I'll be honest I'm extremely proud of the EK D5, the blocks are EK also primochil half inch soft tubing & bitspower fittings. I will experiment again with the pump speed only time i turn it up is to get the bubbles out or even fill the loop because the air traps actually won't pop out without full water pressure it could be because the fittings for the front rad are needed to be on top because the bottom doesn't have enough room so I feel like It's fighting gravity? Lol

Here's a link to Martin's Liquid Lab about number of waterblocks and flowrate to temperature change. Obviously a very old article but still applicable. 0.5GPM is 113.6L/h. You can see increasing flow rate from 0.5GPM to 1.0GPM lowered temp 2.06c while from 1.0 to 1.5 only lowered temp 0.75c, and each additional 0.5GPM increase in flow game less and less temp decrease.

That is very waterblock and radiator specific though so you need the exact same components for the flow estimate to be valid. The change in temps depends a lot on the water block. Some waterblocks see changes of several degrees while others are measured in decimals between 0.5GPM and 1GPM flow rate.

The radiator setup has much more impact than flow rate IMO. Setting up all radiators as either intake or outtake will have more impact. Some radiators as intake and some removing air in the same loop means you get very little cooling from the ones removing air from the case unless you are moving lots of air through the case (additional intake fans). The air coming out of a slim radiator will be closer to water temp than ambient and a fat radiator will make the air close to water temp. The radiators drawing air from the case will operate at much lower efficiency due to the air being much hotter. If all of your fans are attached to radiators then I would expect a 480 as intake to be close to a 360 as intake with 360+120 as outtake.
