Currently have a 1920x on a Zenith Extreme being cooled in by Nzxt X52 (limited to 240mm) using Nzxt AER RGB fans. The CAM controller is reporting widely varying CPU temperatures, jumping up and down between 40c - 60c+ for no apparent reason - it does seem to be a threadripper thing.

Obviously this is playing havoc with fan curve and annoying the hell out of me, also any form if overclocking is out the question as the x52 doesn't have the cooling capacity.

Thinking for changing to -

Any thoughts / views?

So I did order the Enermax Liqtech TR4 240 - it totally outperforms the NZXT on TR4. More consistent and much lower temperatures, the qfan control on the Zenith extreme leaves a lot to be desired by had a another fan controller which was much better.
 
I don't know who makes Enermax Liqtech coolers for them, but according to their literature the pump is rated at 450 L/h.
Nzxt X52 is Asetek and I think they are 40 L/h, maybe 60 L/h.
Either way it's a huge difference in flowrate. ;)
 
The Enermax cooler has the 100% coverage baseplate unlike the Asetek design coolers so you will get better cooling with the Enermax cooler.
 
Oy. Hi there. new here but hope i can join in. I am on noctua u12s air cooling but experiencing some weird issues. cpuid as well as hwinfo seem to spike the temps to 76°C and all on stock fq when rendering. altho the average temp does seem to be around 68ish i am a bit on the uncertain side wether to try and reapply the termal paste. did any of you get to try aircooing stock and full stresstest? is that normal. thx

Don't know the u12 but I'm using the NH-U14S TR4-SP3 with a 1950X.Not run any long CPU stress tests but during some shorter tests general tests such as Cinebench the temps all seem good. Idles at 29C and think it stays under 60C under load. Due to sheer number of cores I'm reluctant to apply unrealistic loads to it. I'm sure I've applied the paste well and I'm sure Noctua have tested their design well so I leave it at that :).
 
TBH, I'm beginning to think my thermal paste application is poor as I see mid 60's in games and prime pushes that up to 87. (That's FMA not AVX too) This is a 1920x @3.97ghz & 1.32-1.36V cooled by a custom water cooling loop with an ek block and 480 + 240mm 45mm thick copper radiators.

Might be case airflow not being setup to supply needed cool air to CPU cooler. Here is link to basic guide to optimizing case airflow: https://forums.overclockers.co.uk/t...-i-put-my-temp-sensor.18564223/#post-26159770

I have considered that. I get the feeling that my pc being housed under my desk isn't helping matters, but the case is too big to go anywhere else. I've resorted to removing all of the dust filtration to help improve things.

This is how the fans are configured.


Air in is done by 4x phanteks 140mm, 1x noctua nf-f12 and 2x gentle typhoon.
Air out is done by 1x phanteks 140mm, 1x 140mm be quiet and 4x gentle typhoon.

I've been considering moving the rear 140mm exhaust up to the top to help promote more flow around the vrm and also moving the 4x gentle typhoons from pull to push
 
Not thorough testing but if any help, Cinebench run 5 times in succession pushed the CPU to 46.25degree during last run, according to Ryzen master.
Timespy bench - CPU temp averaged probably around 35.8degrees although a bit lower towards the end (33) with a couple of peaks above 40, one 42.
That's using the Noctua U14 TR4-SP3 and CPU running stock.

This info is for the person using the U12 noctua cooler btw (not just some random info) :)

Just re-seated the waterblock on the cpu and now after 25 mins of prime small FFT, it's peaked at 75 instead of 87. The paste I used first off had almost separated as there was an oily residue at the lowest point of the IHS. That was the Thermal grizzly supplied with the block. I've replaced that with EK ectotherm using the large blob in the centre of the Z method as gamers nexus suggest as being the best approach.
