CPU temps at 95 C

[DogManPC]

Hey guys!

My CPU temps have always been pretty high which is something I've only recently discovered to be a problem. Under load my CPU reaches 95 C and thermal throttles. I've reapplied thermal paste, fiddled with my power plan adjusted for ryzen CPUs and normal balanced and my CPU still reaches 95 C during load. I suspect it's due to my case and my fans. My front fan is intake at 140mm, radiator fan (exhaust) is 120mm and I've got a rear exhaust at 120mm. My case is the pretty old N500. My GPU is undervolted and the temps are fine. I would hope that I don't have to change the case and that buying and mounting x3 120mm Arctic P12 Silents (result would be (x2) 120mm Intake front, (x1) 120mm back exhaust, (x1) 140 radiator exhaust). Pretty sure my Motherboard doesn't control more than 1-2 fans so I would have to buy a splitter. PC is clean from dust and the Windows is relatively freshly reinstalled. 

 

 

OS: Windows 10 Pro

PC Case: N500 KKN2

CPU: Ryzen 7 3800XT (Not overclocked)

CPU Cooler: AeroCool Core plus (There are definitely better, but shouldn't get to 95 C under load?)

GPU: MSI RTX 3070 Ventus 2X OC

Motherboard (Version): Prime B350M-K (5602)

RAM: DDR4 2x8 Corsair (2666)

Radiator seems puny and inferior design.

I mean even $20€ Aliexpress Snowman cooler would probably cool ~10-15C better. Don't recommend that either though.

I'd definitely say that the AeroCool Core plus is the weakpoint here.. Its an average cooler at best and the Ryzen 7 3800XT is a hot 8 core CPU. When you say under load, are we talking normal gaming or 100% loads?

When running Cinebench the CPU climbs up to 95 C within the span of 10 seconds. It varies during gaming, but it does come close to/reaches 95, even when the CPU load isn't that close to 100%. I'd say it consistently reaches 85 C even when casually gaming.

Cinebench is a stressing the CPU to its absolute max and seeing throttle with the AeroCool Core Plus on a 3800XT does not surprise me one bit. That cooler is not designed for such loads on such a warm chip. There is no way that cooler is enough for the 3800XT at heavy loads.       If you want to see better temps you need to change the CPU cooler do something more adequate for your CPU, putting another 120mm front fan is not a bad idea either.

There is no way in hell that you are gonna cool that R7 3800XT with that cooler.

I'm looking at a few AIO coolers. Do you think the Cooler Master MasterLiquid ML240L V2 would be a decent choice? I don't want to spend too much on a cooler and this one seems pretty decent.

Any reason why you want an AIO over a higher end air cooler?   AIO's are nice but they also have a higher risk of failure ( They WILL fail at one point ).   I had Cooler Master MasterLiquid ML240L and I was not happy with it at all, the fans were loud and started rattling after a year and overall felt like a cheapish product.  I got it for free with a CPU purchase so.

Here's one that is much cheaper but will be about the same temps as a 240mm aio.

Would this be around the same size or smaller compared to the AeroCool I have? GPU does sit pretty close to the cooler in my case.

My GPU sits pretty close to my cooler and the AIO looks to be a lot smaller than the high end air coolers. I'm worried I might buy an air cooler that is way too big to fit.

Seems to be a standard ATX case. Any air-cooler should fit very precisely. Only thing to watch out is cooler height usually - 162mm in this case. And of course if it fits the right socket, but that's obvious.

Thats alright. Its not sitting closer to the CPU that on other motherboards.  Here is a video of my system with an NH-D15 ( Video was made for something else ).  The peerless assassin will fit in your system without problem.
