DAN HSLP-48: A powerful sub 50mm heatsink

dondan check this out, the fan is touching the RAM but it is OK.
CoolJag Falcon II + Noctua A12x15 on Z270 ASRock Fatal1ty Z270 Gaming-ITX/ac (MB and MOSFETS heatsink replaced) with Innodisk DDR4-2400 VLP UDIMM Non-ECC UnBuffered M4U0-AGS1WCSJ

Loque did some nice perf tests on what would be close to an identical case layout and expected results

Time to share the results from theHeat sink testhttp://louqe.com/img/img/ext/ext/GhostS1CPUheatSinkTest.pdf

Note that we have measured the noise levels closer to the case this time and on the CPU-side in order ger more articulated results

The nh-l12 performs pretty well. If only the cnps8900 was more readily available.

Also, we know the hslp-48 ver 1 perf amd can now compare to these other heatsinks. How will the hslp-48 ver 2 surprise us?

Built my new system today. The i7-8700 throttles pretty badly with the L9i. Really hoping this heatsink works out.

I'm curious about this, because the L9i performs better/on par with the Intel stock heatsink, and the 8700 comes bundled with one. Does it throttle with the stock heatsink too?
 
I didn't bother to try it, but other users are reporting it does.

Basically, this CPU is an "up to" 4.3GHZ turbo but sits at about 3.4GHZ at 100C.
 
That's just insane, how can Intel bundle a CPU with a totally inadequate cooler... Thanks for letting us know. It seems like if you want to go L9i, it's 8400 or down.

I agree, the boosts for an 8400 are as follows:

1 core: 4.0 GHz, 2 cores: 3.9 GHz, four cores: 3.9 GHz, 6 cores: 3.8 GHz

From what I am hearing 3.8 on all cores with the 8400 will saturate an L9 cooler. 4.0GHz on a single core is also plenty quick. Buying anything more than an 8400 is probably a waste. If you spend some time optimising voltages with an unlocked chip you might get better results but the money is better spent on the GPU.

Edit: Sorry this is off topic I thought it was the A4 thread...

Very nice! What brand of fan clips are you using to mount the Noctua fan?
 
This has probably been addressed, but is there a chance the HSLP-48 will match the cooling capacity of the 545LC? I think watercooling completely changes the game for the A4-SFX, everyone and their mom will be running an 8700K (or whatever the equivalent is next year) in them. There will definitely still be a place for the HSLP-48 though in Dan's and other cases, but I'm just curious what the performance will be in relation to a 92mm AIO.
 
Here is a small update:

The heatsink manufacturer that works together with Lian Li for the HSLP-48 project is the same one that made the be quiet heatsinks.

They made two prototypes one with 6 heatpipes and the other with 5 heatpipes. Lian Li send me pictures and warned me that the quality isn't good and acurate because the manufacturer used electrical wire extrusion to made the samples.

I told them that I can't work with samples that are far away from the final product and that I will drop this project if I can't get better samples.
Heatsink samples are crazy expansive so I was very unhappy with the situation.

So Lian Li had a meeting with the manufacturer and I will get new CNC made samples in the next 10 days.
The quality will be very close to the final product that will be made by stamping.

So I think the new one will be much better. This is very important for the project because I don't have a big budget for it.

I am realistic with this project. I think it will be hard to get the MOQ of 1000 units for the campaign. Also if we can reach 1000 units this project is from a businesd point of view less interesting than a case project, because the marge is not that high and the work around it with developing, testing, manual making and logistics is nearly the same as for a case project. Increaseing the marge isn't possible because the HSLP-48 is already more expansive as competitors. I need to sell 4000 units to be on a level to say this project was worth all the work. Don't get me wrong also with 1000 units I will made profit but not that much. This is the reason why my budget for prototyping is low.

I will have more information in 10 days.

I still NEED the HSLP-48! I want to clock my 6850k to 4GHz and it not turn in to an oven.
 
Well if it doesn't work out it was a good run.

No matter what, I'd like to say that from seeing and participating in a bunch of kickstarters and crowd funded campaigns for various products in the past 3 or 4 years, dondan you have been the most communicative and, for lack of a better term, trustworthy about your projects. Kudos to you, you're a model for how this stuff should go. :)
 
Dan, you can also think of it as a long-term investment to increase sales on the A4-SFX. The case will be quite popular when it goes on sale outside of crowdfunding, and I think most people would choose to buy it bundled with the HSLP-48 since it'll be by far the best air cooler for it. Also, if you have the best super low-profile cooler on the market, you'd get demand. You may not get 4000 sales in the crowdfunding campaign, but in the future if the product becomes available for sale, you would exceed that number for sure.

I will buy one even though I have no use for it, just in case I need something this small in the future.
 
Dan, incredibly frustrating for you… and I sense a bit of 'fatigue' communicated in your latest update (not at all surprising considering the time/effort you have made).

You (we) can all get incredibly close to our projects from time to time (especially ones that are demanding/tricky) - and as a consequence lose sight of the 'bigger picture'. I believe that there is a huge pent-up demand for a great cpu cooler… and the HSLP-48 is that cooler - it is super-well-designed and looks absolutely fantastic!

I think you would get a significant number of backers… how quickly did A4-SFX v2 get funded? (and the number of?) - a large proportion will be customers (I will be buying). Then there will be many other itx case builds interested in another option for cooling… especially for OC'd chips.

Is there is another strategy that could be applied?… one that you may have already considered… (apologies for stating the obvious if you have). Form a 'product partnership' with a cooler manufacturer and let them develop/produce (at their cost) and pay you royalties etc. This might get the cooler 'to market' sooner and with less financial risk for you - especially as you say the 'margins' are slim. But am I being naive here?

Perhaps just by doing what you have been doing - creating a 'stir' in the cooler marketplace - the major manufacturers are now creating new high-performance low profile air coolers (you might be better informed/aware of this?) and the SFF community will end up getting a better cooler than currently exists… just not a DAN HSLP-48

That all said… really looking forward to the results from the 'more correct' prototypes - and hope it gives you the 'energy' to continue with the project.
 
If you're completely fed up with getting prototypes for your new designs, the temperatures of the existing ones looked pretty damn good already....
Pretty baffled by the fact Lian-Li would ship cooler prototypes that vastly under-perform compared to production samples. Aren't performance and build quality the main reason to get them in the first place?
 
If you can match or beat L12S performance, you have a real winner.

Regarding the RAM clearance, what if you used normal RAM, but just moved the 120mm fan a little so it didn't interfere. Would that be worse than using a 92mm fan?

Problem is that there’s not a lot of room on an ITX board. Board dimensions are 170mm square, and we’re talking about a 120mm fan. Most boards have a row of connectors on the edge of the board, then two ram slots. Moving the fan over so that it doesn’t overhang the ram is getting very close to the I/O area.

As for the L12S- that’s a much larger cooler.
 
DonDon you can Start the kickstarter Projekts c4 and Hslp-48 at the same Time and can offers in the project c4 the option to order the Hslp-48 too. Maybe you sell then more as 1000 pieces.

I think there may be just about 120mm of space between the edge of the inner RAM slot and the rear I/O of most boards...? Mounting would be difficult, but I think it would still cover over 90% of the heatsink and probably work better than the thicker 92mm fan. I have no idea though.

Is the L12S really that much larger? It just seems taller i.e. the heatpipes are raised more to accommodate standard RAM, but the size of the heatsink doesn't seem that much larger.

I guess only Gigabyte AB350N-Gaming WIFI has the chance to mount fan with normal height memory and is pretty close to 8-pin CPU power connector:

Thanks for that graphic! I was wrong then... I wish there were more/more widely available VLP options for DDR4. Can't wait for dan to get the new samples. I'd like to see 92mm vs 120mm performance. The 92mm fan is thicker, so maybe decibel for decibel it won't be that different.
 
Oh right, I was thinking of the L12. I'm getting everything wrong. Thanks for the clarifications everyone. I can't wait to see testing on the new version with different fans.
 
TOMORROW MAKES IT 10 DAYS!!! I can't wait to hear the news of things being normally late :D

Also, if you decide against the project, will you be selling the samples that you got? I would very much want one.
 
FWIW-

Wahaha360 confirmed that the case he's prototyping (~7 liter console style case with 2-4 15mm fans) will have a 48mm cooler height limit, so that's another possible case where owners would like this project.

Innodisk is apparently working on 2666mhz VLP DDR4 with Samsung chips, which would work nicely with this and a 120mm fan.

What project is this? Is it the xbox looking steamcase?

Yes. If you haven't been following recently, the ideas is to have a fan bracket under the lid (if lying flat)/side panel (if standing up) that would hold two thin 120mm fans. Gpu would be next to the motherboard, like a Sentry, but facing the same way as the CPU. It would be possible to have another fan bracket over the GPU for a total of 4 120mm fans. At any rate, he recently confirmed that it would take up to a 48mm heatsink under the fan bracket.
 
Today is the day Lian Li gives some updates. Hopefully it isn't something like "we got it and you should have it in 20 days".
