Thermolab (Cooltek) LP53 review

If it is not too much to ask, can you run one more test? Compare the LP53 with the noctuna 92mmX14mm fan vs the LP53 with its default fan.

Yeah I can probably do that. That should be pretty easy. I'm almost certain it will be both louder, and slightly cooler, maybe a degree or two. I doubt it would be a drastic difference. Also keep in mind it definitely won't fit in Sentry with the stock fan.
 
In other news, I received the Thermolab ITX30 today. It is TINY! It's basically identical to the lp53 with the fins cut shorter. It has an 80x10mm fan by default but an 80x25mm or 92x14mm should be compatible with sentry. Though why anyone would chose this over the lp53 is a mystery as it is the same price and won't match the lp53 performance. Perhaps for even slimmer cases it would work. I'm curious to see if it fits in my Silverstone PT13b. Let me know if you all want me to bench this cooler too. I expect it to be less than or equal to the nh-l9i though in performance.

Does a 92x25mm fan exist?
I would love to see you bench it with noctua fan, and whatever huge fan you can fit
 
AND 53Db! I can still hear the screams of my delta 60 and 80 fans from back in the duron days... :)
 



I hope you guys don't buy all of them and save one for me, but in Newegg they are selling a delta fan that is 92mmX20mm which should fit nicely with the lp53 and pushes 59.54CFM at 3000RPM and is actually not too noisy 38DBA

20mm thick will be very tight in sentry. LP53 fins are ~5mm higher than the nh-l9i fins so the fan is raised up 5mm higher. The 14mm noctua fan will fit no problem but 20 and 25mm? Very close to being too tall.
 
Jesus, 102.6 CFM at 4800RPM!! Now that'll do work. I love digikey, so much good stuff, used them twice, and been looking at there micro fans.

That's so much airflow I'd worry it'll blow the ic's and caps right off the damn motherboard. Haha that's twice the airflow of the noctua 92x14mm fan. At some point the limiting factor will be the heatsink surface area and working fluid of the heat pipes.

SaberPL said that NH-L9i with 92 x 25mm for a total of 48mm fits inside Sentry with a slight gap so the LP53 plus a 20mm fan should be fine given that it adds up to exactly 48mm.


I was worried that it wouldn't fit but this changes everything.

From my own anecdotal test the nh-l9i with 25mm thick fan still can't match the lp53. But maybe the lp53 will work with a 20mm fan. Maybe. Someone will simply have to try when they get their sentry.

Or there's always the ITX30 with a... 40mm thick fan? If such a thing even exists haha. I'll try the ITX30 soon. Just got around to ordering new thermal paste tonight. So should be here Tues or Wednesday.

For people who are looking for slim fans, or 25mm fans there is this great Slim fan list in another thread. Just want to put it here so everyone knows about it. Not sure if the people watching the Sentry thread know about this list.

What are your temps? And in what case? (or is it open bench?)

I ran out of thermal paste so I haven't been able to do a proper test but below is what I've seen previously in an open air situation.

I am low on thermal paste so shuffling coolers around isn't ideal at this moment. So I made an anecdotal observation using the 25mm thick fan. It's not a proper comparison but, I had the NH-L9i with the 92x25mm fan on my girlfriends pc with an i7-4790S (65w tdp). Unfortunately it has no OS as I'm waiting for a new ssd for it so it's just sitting in bios. In bios the cpu sits at 1.2v and 4ghz on the 4790s, and 1.2v and 4.4ghz on the 4790k.

After 20 minutes sitting in bios with the nh-l9i and 92x25mm the 65W i7-4790S is sitting at 48C.

At the same time I had my 88W i7-4790K with the LP53 and 92x14mm also sitting in bios. The cpu is at 40C.

So the noctua with thick fan can hold a 65w tdp cpu at 48C and the Thermolab with the thin fan can hold an 88w tdp cpu at 40C under similar conditions of 1.2v on two haswell i7's. It's not a proper empirical comparison but I think it suggests that 100% copper makes a bigger difference than shoving more air through a nickel/aluminum cooler.
 
Hello, I hold a i7-6700t (35w) you could try your cpu downgrade fanless, if possible.... Thanks :)

I have a 35W i3-4130t. Would you like me to try that with the lp53? I am skeptical of this working. Even a fan at a silent speed of 400rpm would be very effective. If silence is required, I can try no fan with 35W cpu.

Actually it depends on the room temperature but mostly I agree that even a very low rpm fan will be better than no fan at all.

Like you said SaperPL proved that adding a fan too close to the cover will actually make it perform worst, so I am no longer planning on getting the delta 20mm but if nobody tries it i might get 120mmx15mm slim fan and see if it fits and how it performs and if it doesn't fit I'll just return it.
 
you can try the fan and no fan to see what temperatures are there? thank you

I am planning to do the test with no fan on a 35w cpu, and any other tests next week. Hopefully I will have more time then. Sorry for the delay.
 
Hello, I have an i5 6600k , which is a 91W cpu. I am having trouble because I don'y have enough money to go out and purchase a lower watt cpu. Will the LP53, though extremely overpriced, keep my cpu cool? I just don't really have any other solutions at this point.

It keeps my 88w i7-4790K at reasonable temps. Skylake and especially Kaby Lake tend to run hot. It should work though. Better than other low profile coolers. Do you need a low profile cooler?

Yeah I actually pre ordered the sentry so I just need to get my cooling situation situated and I will be ready to go!
 
Ok, I figured, just thought I'd check seeing as this thread isn't exclusively for Sentry.
I was thinking of getting the i7-7700 locked instead of the K unlocked version because I'm afraid that the temperatures will be too high even with the lp53.
 
[Quote = "Ej24, posta: 1.042.807,304 mila, membro: 293291"] Ho in programma di fare il test senza ventola su una CPU 35w, ed eventuali altri test la prossima settimana. Spero di avere più tempo poi. Ci scusiamo per il ritardo. [/ Quote]

Without any hurry, so the sentry will not come tomorrow :)
 
You guys are focusing to much on Intel's 'TDP'. As can be confirmed by SPCR, there's no magic to Intel's 35w or 91w chips. These are mere suggestions for the type of cooler needed. A 91w chip underclocked and undervolted will act like a 35w chip if specced the same. There's no binning. All the chips are linear. Increased frequency and voltage results in more heat. So adjust your chips accordingly and enjoy your builds.

It can also help to choose a motherboard that consumes less energy, ditto for graphics card if you're going to be thermally limited like in the Sentry or A4.

Yeah, 7700K is an insanely hot chip from what I've seen in reviews on YouTube. Most reviewers are finding, out of the box, the 7700k is running at almost 70C with water cooling. Delid helps by about 15C. So that may help. Epitaphic is right, you can also undervolt or lower the max wattage in bios to make a 7700K behave more like a 65W locked 7700. Perhaps in the future there will be a great low profile cooler that can handle an unlocked cpu, in which case you will already have the unlocked cpu, should you choose the 7700K. Until that magical cooler arrives you can just delid and limit the max performance of the 7700K.

A rysen chip whose price has been leaked actually is peaking my attention the AMD Ryzen 7 1800 should hopefully be under 450$ and speeds similar to the 7700 plus it having 8 cores and all of that at 65W. Even if single core performance is worst, it still an amazing choice for a small case like the sentry with the lp53 cooler being able to easily handle the 65W. Unfortunately, the real problem with Rysen right not is no motherboard available.

Motherboards and Rysen will be released at the same time, both are stocking up as we speak as this will not be a "paper" launch like their GPUs. Full SKU range availability when released.

I'm curious to see if it fits in my Silverstone PT13b. Let me know if you all want me to bench this cooler too. I expect it to be less than or equal to the nh-l9i though in performance.

Would like to see the ITX30 benched against the LP53 with the same fan of your choice, just to see what the difference in temp is by losing the ??mm^2 worth of fin surface area. Although I guess it's hard to know how well matched a fan/sink combo is to know if we're fan-bound or sink-bound in ability to remove heat from the CPU. In the fan-bound situation, changing the LP53 to an ITX30 shouldn't make any difference, and we'd have to go mucking about with different fans.

I guess the other interesting comparison would be the ITX30 vs the NH-L9i, as that's what most everyone should be familiar with in this form factor, and whether it should be a contender for people who have been looking at the L9i.

Thanks for checking all this out. I actually just ordered both the LP53 and ITX30 before I hit page two of this thread and saw that you'd also ordered an ITX 30. For science!

When mine come in if it hasn't been done already I'll try drilling the 72x72mm pattern into the corners of some 92mm fans to get on the stock LP53 mounting posts.

The more I look at this stuff, the more it seems like the SFF community needs a ~140x140mm heatsink that clears ram and IO ports of a miniITX, with centrally mounted underslung 92x14mm fan..

Yeah the problem is the height of that 140x140 heatsink. The way I see it the heatsink needs to be very slim at the top then under the fan.

Here is a little concept I made based on the Kozuti from Scythe:

Nice mock-up! Yeah, I didn't think it'd necessarily be easy to make it all fit with the various motherboard configurations, but a bunch of time reading ITX specs and spent in a 3D modeler should sort that out :)
 
just got myself an LP53 and mounted a 92mmx14mm noctua fan to tame my delidded 4770k.

This is crammed inside a node 202 at the moment and prime95 would still hit 95 C or more.

Used to have a deepcool gabriel that does not make sweat in this setup. Did i get a lemon heatsink? or am I expecting too much from LP53

I was planning to transplat this to the Sentry Case -- probably still going to be on the hunt for the right CPU cooler (thinking of taking a gamble with the Cryorig C7).

C7 is LOUD due to turbulence when next to inlet, I've got a C7 in the Dan A4, it's unacceptably loud. Need to look into maybe fitting a bigger slim fan on top of it.

It's possible you're cooler may be a lemon. It's impossible to say at the moment because we still have such a small sample size. Is your 4770K running at stock configuration or is it OC'ed? It's worth noting, I didn't run prime 95 for long. We're talking about powerful cpu's and the tiniest heat sinks so prime 95 just isn't realistic. It's an overkill test too, unless you're folding or calculation primes all day. I find gaming benchmarks to be much more useful.

Also I found the node 202 to be a terrible case. Just small enough to trap a lot of heat and just big enough to have a big gap above the cpu cooler to suck in the trapped heat. Hopefully slimmer cases like Sentry will alleviate this by getting the cpu fan closer to the fresh air.

I may have found out the problem. I was using prime95 28.* version. I tried prime95 26.6 and temps were ~75s. Is there anything special with prime95 26.6?

Also this is just stock 4770k no overclock.
