[SOLVED] NH-U12S SE-AM4 and high temps issue

[BES]

Recently bought NH-U12S SE-AM4 along with:

AMD Ryzen 9 3900XT 12-Core 3.8 GHz Socket AM4 105W 100-100000277WOF Desktop Processor

and a

MSI MEG X570 ACE Gaming Motherboard AMD AM4 SATA 6Gb/s M.2 USB 3.2 Gen 2 Wi-Fi 6 ATX

It doesn't seem to be pressing very hard onto the CPU, saw temps of 175F ..under light load, max temp for CPU is 200F ..according to AMD, 175F is a bit too high, was expecting like 80F idle and 120-140F loads ..it's Hovering between 110 and 130F at idle, doing nothing but opening web pages..

I shut the PC off and took the heat sink off and it didn't appear that it was fully touching to cpu, based on the way the thermal paste was spread, it wouldn't tighten down any further, im using the brackets provided and tightened it as much as possible..

Also using arctic cooling mx-4 thermal paste, which is what I normally use.

But is it normal for it to not seem to be tight enough on the CPU?

Is it normal to get those high of temps with that CPU?

Im not OCing it ...but I had it on normal/auto settings for the CPU.

Celsius is the norm around here - or with PC hardware in general. Don't use Fahrenheit.

[It doesn't seem to be pressing very hard onto the CPU, saw temps of 79C ..under light load, max temp for CPU is 93C ..according to AMD, 79C is a bit too high, was expecting like 27C idle and 49-60C loads ..it's Hovering between 43 and 54C at idle, doing nothing but opening web pages..]
^I took the troublesome statement, fixed it, and...

There's no evidence of a thermal issue present from that post.
As for the 'high idles': Welcome to Zen 2, mate. That is normal.

I was considering doing the conversions with a / didn't think it would be an issue..I have all my temps set to Fahrenheit on my PC. I am surprised it gets that hot though ..had a 2920X threadripper before this and it's temps weren't going much past 71C even during full load and it's the same core/thread count and 500mhz less base clock than the 3900XT and I was always hitting 4.3Ghz without OCing it.

Also, why does it seem like the CPU cooler isn't pressing hard enough onto the CPU? ..it's the AM4 version with the proper brackets.

Umm, you can't accurately compare the 2920X to the 3900XT like that...

Is the backplate loose? Probably not, because I'd imagine thermals would be even worse, to the point of throttling.
Does it need to be tighter? I mean, with some other coolers, you can over-tighten them and then yield a cpu error because of it.

I compared them because the 2920X has a 180W TDP and the 3900XT only has a 105 watt TDP and the 2920X ran at much higher then their rated 68C max temp, that's always been wrong, I said I wasn't OCing it ..the only reason why my 2920X ran at the temps I specified was because I disabled boost all together, boost was making it go much higher 75-82C ..ish witht he best air cooler I could find ..I asked about those temps and everyone says .."oh thats normal for threadripper"

 

[Phaaze88]

Huh. Well, that happened...
I'm thinking that 68C is for a completely different thermal sensor altogether; if those 75-82C readings were correlating to that particular sensor(68C), it should've shut your PC off.
Just like that confusing mess with Intel's Tcase and Tjunction.

Did you do the same mistake as me and not tighten the cooler ALL the way? At first, I stopped when I heard the springs creak on my NH-D15. That caused me to get 90C spikes in AIDA64 sitting at 88C.

Remounting the cooler but tightening it until the screws stopped and I couldn't turn them anymore (intentional design by Noctua), reduced my temps to 85C spikes and sitting at 83C in AIDA64.

Unless im a total weakling it's as tight as it's gonna get, for the heck of it I got a different one that should definitely cool it, it's the same one I had on my threadripper, pretty much: be quiet! 250W TDP Dark Rock Pro 4..

Dark Rock Pro 4 is on par with the NH-D15 so yeah
