Reading Ej24's thread about the LP53 CPU cooler, I'm wondering if the ARTIC Freezer 11 LP wouldn't be a good proposition as a middle ground between the nh-l9i and the lp53 or maybe even a better overall proposition than the lp53.
It has the same overall height (~53mm) than the lp53 and therefore its fan would have to be swapped to a thin fan as well. And maybe its aluminum fins won't give the same performance as the lp53's copper ones.
BUT the Freezer 11LP gives me the impression that it will be a better performer than the nh-l9i (since its beefier and recommended for TDP up to 95 Watts) while being a more quality-assured product than the lp53, with a better engineered mounting system and fan retention system that seems to be a lot easier to work with to install other fans (since it uses standard screw holes in all-open spaces), as well as having a much broader availability (both Amazon and Newegg have the Freezer 11 LP in stock and readily available in the USA, for example) and being considerably cheaper (~$17 USD) than the lp53 (~$55 USD).
OverclockersClub have some nice photos of the Freezer 11 LP's heatsink and fan retention holes/screws
So, guys... any thoughts?

999%... One purchase away from 1000% and the first 1000 cases funded.
Hmmm, There are currently 820 backers; I bought a WHITE 20 days ago and my order number is 853![]()
You have to consider the refunds, there are quite a bit of them because some people wanted to change the colour from black to white for example, and we have no power over switching the perks and orders.
please tell me as soon as the company is complete, and if by that time will still be not sold 2-packs of white case (or white + black), how do you do with them? I can be able to buy a 1 piece white case immediately after the end of the company in some other way?
As I explained before - we're cannot switch perks since we're bound by indiegogo terms to deliver on spec. We don't want to do exceptions since this would make a mess when everybody wanted to do this and at the same time we don't want to add more perks because it also would make a mess.
We are not going to be selling the "remaining" white cases either because we have to deliver to backers first and that means if you want to wait out and see if we will be selling those you'll be disappointed with the fact that you'd have to wait until we deliver all other perks being the last one to get this case.
TL;DR: we don't want to make exceptions nor add more perks because that would make logistic nightmare for us when we would open that gate. We don't want that.
The problem originates from how indiegogo handles limits - we cannot set a limit on item type but perk type and there are no limits on options.
Just created a account just to ask this one question. Are you planning to sell the white sentry cases after the indegogo campaign concludes? Really bummed that it sold out so fast.
UPDATE: Sentry CPU cooler tests results
Read carefully as there are a lot peculiarities about how CPU coolers behave inside Sentry!
![]()
1) What CPU coolers were tested?
2) Test Bench:We have ordered the coolers we have talked about earlier in this thread:
- Noctua NH-L9i
- Scythe Kozuti
- Zalman CNPS2X
We have topped that with what we already had:
- intel Copper-Core Box
- Cryorig C7
Finally we also wanted to check out fitting and performance coming from 92x25mm fan mounted on top of NH-L9i. We did that with Arctic Cooling F9 which has pretty close parameters to Noctua 25mm fan and we could get that with our local distribution faster than the one from Noctua.
3) Testing methodology:CPU: 65W Skylake, the i7-6700

Motherboard: Gigabyte B150N Phoenix Wifi
![]()
Thermal compound: Arctic MX-2

4) Tests summary![]()
Noise monitoring at 1 meter in front of the test bench
30-minute tests (10-minute tests are too short to stabilize the temperature ramp) for each configuration:
- horizontal position - Prime95 Maximum Heat (full CPU load test)
- horizontal position - Heaven Benchmark (gaming load test)
- vertical position - Prime95 Maximum Heat (full CPU load test)
- vertical position - Heaven Benchmark (gaming load test)
Tests were run in stable ambient temperature of ~25 °C that was measured at two locations: on the desk and
at 1 meter in front of the test bench.
Tests were run in room with ambient noise ~45,5 which corresponds to quiet urban area

Thermal performance:

Not much to explain here except the 92x25mm Arctic Cooling F9 fan on top of Noctua NH-L9i- it should perform ~50% better (the fan itself) than 14mm NH-L9i fan but putting it directly against the case cover makes it harder to suck air and in effect it performs even worse.

Result analysis:
Coolers in vertical position tend to be slightly louder under full load than in horizontal position perhaps due to the fact that they are trying to push the hot air downward which effects in running at max RPMs. Rotating the fan to push the air out instead of pulling it inside is worth a try here but results may vary depending on cooler construction.
Coolers in vertical position tend to be slightly quieter in idle than in horizontal position. This is likely effect of the case orientation in reference to the noise level monitor/the user position.
Noise level is significantly higher when putting the 25mm fan directly under the air inlet because the fan blades are slashing air against it. This result is consistent with what we've already knew about those configs from our tests with Cryorig C7. Note the fact that intel's flower fan doesn't behave this way because it has open frame and can pull air from all around and not for the airflow directly from above.
Finally what is commendable is the fact that in vertical position intel box cooler is inaudible in idle and we had consistent results in four prototypes running: Xeon E3-1230v2, Xeon E3-1231v3, Pentium AE and i7-6700 and combined with semi-passive cooled power supply it is incredible that the whole machine is completely silent when simply browsing the net.
6) Final Verdict:Intel copper core box cooler

Notes:
Not a stock cooler anymore - current generation K SKUs are sold without the cooler.
Can be bought in new condition from owner of previous generation K SKUs or owner of Xeon E3 processor and is dirt cheap in comparison to other solution since it can be bought as cheap as $3 because most of the owners are choosing bigger aftermarket coolers.
Its noise is slightly more audible/less pleasant in the middle of its RPM range so tweaking the temps to RPM ratio in bios settings might be a good thing to consider. Note the fact it has same noise levels while having different temps between full load and gaming load tests.
It is the easiest cooler to install and maintain.

Notes:
Fitting a 25mm fan on top is possible but it doesn't really help.
It will fit under the drive bracket if you have the worst case scenario of motherboard layout.
The noise is more pleasant in the middle of RPM range than intel's stock cooler. It might be better if you're not fully loading your CPU while gaming and don't use the headset while playing.
It also performs slightly better than intel box cooler, but until you have go with 95W CPU, you might want to save those few bucks here and buy a better GPU or SSD.

Notes:
It is significantly louder than NH-L9i because of the small slim fan that is pull air through the radiator. I'm not a fan of such constructions from now on...
It also is not properly designed because the heat pipe ends are outside the socket area and low enough to collide with quite standard now memory radiators even the ones like small HyperX radiators.
Cryorig C7

The mounting of this cooler is not properly designed as mentioned before. First we had to grind down the crews a bit so they wouldn't stand out ~8.5mm below the motherboard while mounted on Skylake CPU. Note the fact that we have 7mm stand-offs and ATX requires only 6.35mm down there.
Josh from NFC also had to shrink the screws somehow but for a different reason - they were too big in diameter for his motherboard holes.
After mounting it actually looked like the tension made the gap between the cooler base and CPU cover because the base was then sitting on the coils around the socket. We tried to put an aluminium shim between the CPU and cooler but in the end the gap between the fan and inlet was so small that it run at over 50 dB.
We may try to check out some thick termopad as a mounting solution for C7 when we get some time for more testing in the future, but so far it looks like it's not worth your money.

It is REALLY small - the photographs make it feel slightly bigger.
We've caught bad luck with this one - the unit we've got has a faulty PWM control and its fan is running like in idle all the time. I'm going for RMA with this bad boy sometime this week.
It also looks like it may be going for End of Life now so it might not really matter for you.
Finally I still wonder if it's really that good to support 120W TDP CPUs since Valve went with it for their Steam Machine prototype. It slightly outperformed both intel box and NH-L9i when running idle, but it didn't have best results in reviews we could find online.
Nothing really changed in terms of what we think you should do initially - If you're buying intel cpu then take it without BOX cooler and buy copper core cooler for few bucks online. That's for a start until you know if you really need to spend that additional money for better cooling.
For aftermarket coolers it looks like NH-L9i might be the best choice from what we've tested, but with all the data we think that you may want to check out other coolers in this format such as Silverstone Argon AR05 or Cooltek ITX30.
And no, Gigabyte Phoenix series are not 'cheap mobos' - those are mid range products and we have decided to go with them for testing because mid range should be more representative tests than picking out ultra-high-end board that not everyone will take.
I am not sure what kind of people are you guys expecting to buy a 200€ case!?!?!
If they spend that money in this case, they will definitely go with high-end components for their PC... Not only the motherboard. It's true that not everybody will do that, but I am not afraid to say most of the people who is backing the case and willing to wait for it is no normal customer...
They won't case about 20€ if that gives better performance.
I have tested C7 on my Haswell Xeon on B85N Phoenix. It's loud as hell under load and I've talked about this. It's the same scenario as when putting 25mm on Noctua.

Anyway C7 is poorly designed because in the whole point of fitting this cooler within the size of intel box cooler they didn't think to check how it would perform if the case inlet was directly in front of it. And they are promoting it for small form factor cases, so we can assume that something like STX cases will have the similar problem?
You mean loud as hell under load in sentry case? What's tdp of your Xeon?
This is my Xeon E3-1231v3 - 80W TDP
http://ark.intel.com/pl/products/80910/Intel-Xeon-Processor-E3-1231-v3-8M-Cache-3_40-GHz
The problem with C7 in Sentry is that if you put such fan directly facing the inlet this close then the fan gets starved quite a bit (note the fact that perforation reduces the area of flow cross-section if you want the panel to remain rigid and we do want it) so it will go hotter and the RPM will rise to maximum and additionally with fan being this close to the mesh surface it slashes air against it.
In comparison the intel boxed cooler has quite a few mm from its top to the fan blades and is open at the sides so it can suck air from around using more inlet area than C7.

It is also why NH-L9i works better with default fan than with 25mm one because of that additional 10mm of space
Also if you don't mind a little extra. If you have a 120mm fan lying around can you give us some insight into whether a 120mmX15mm slim fan will fit into the case on top of a 28mm heatsink (the lp53) with a regular motherboard? (Specially whether it will interfere with the SSD on top of the motherboard or the typical 34mm tall ram)
I'm assuming due to the height of the rear i/o the 120 fan will be that close to the grill it will make a racket.I've put
120mm slim fan in our assembly:

They won't care about 20€ if that gives better performance.
edit: Also, my # is 1136. I took my time and wasn't worried about it being long run.. Frankly, I just built my system today with a temp corsair air 240.
