CPU Idle temps high

[Mr_bubblezz]

hello I've been having some weird issues lately,

so at boot my CPU will be at 50c immediately from cold boot (overnight fresh boot),and on idle ill be anywhere from 50-60c in windows home screen. when im playing games like Overwatch or any desktop game (not VR) ill get tempts up to 90c until I would blackscreen/ bluescreen, but the weird issue is the CPU cooler itself is cold to the touch (I've reseated it about 5 times switching coolers and such no dice using nacua, IC Dimond, and stock comes with cooler compound) . I did switch to a new cooler and same and had the exact issues (had a 240m corsair cooler AIO switched to Nactua D-15)  im feeling its a CPU failure possibly but unsure I do have crash report telling me "hardware failures. it can be heat related, defective hardware, memory, or processor" I ran a memtest86 for a 10 hour tests and for 0 issues on my ram. 

 

-CPU: 5950x

-GPU: EVGA FTW 3090

-Motherboard: Viii crossfire black 

- power supply: EVGA SuperNOVA 1300 GT

 

-1st cooler corsair 240 AIO 

-2nd cooler nacua D-15

When you replace the thermal paste, and then later replace the cooler, does the paste show signs of making contact between the CPU and the cooler? 

[Mr_bubblezz]

Yes it looked like a good spread every time, I've built many PCs in the past but this one has me stumped

The NH-D15 should have no problem cooling that CPU. If the spread and contact looks good and you're not over or under tightening it, it sounds like it could be a defective temp sensor. It's not super common but can happen.

 

It can also be an airflow issue with the case, depending on the case you are using it could have just bad airflow in general causing the temps inside to rise and the cooler to not function as well.

Can you list your case make and model and how you have the fan configuration setup?

im using a corsair d400 airflow with 3 intake and 3 exhaust, (6 total case fans) all on turbo settings so they are full tilt when over 60c and temps will still rise and its not on carpet or anything blocking airflow and its pushing a lot of air (i did only have 1 exhaust before and added 2 more and no change)

also there is no overclocking in the CPU (never was) and the ram is on 3200mh DOCP thats the only overclock (if u call it that) in the whole system

Yeah that case and fan setup should be fine, with the NH-D15 there should be no reason your CPU is overheating. Honestly, it sounds like it's a faulty temp sensor on the CPU. Have you checked to see if there are any bios updates available for the motherboard you have in the system? If so I'd do those as a last ditch effort to see if it's some sort of weird firmware issue. If it still has problems next test would be trying a different CPU in the socket or replacing the 5950x all together.

thats what ive been thinking its a bad CPU I was dreading, and yeah updated the BIOS its up to date. one thing im most confused about too is when it started "overheating" it never throttle. my question is, even with a bad temp sensor would it throttle thinking its overheating?

5900X owner here. Mine usually peaks around 70C, 80-85C running hard (which takes some doing), so I'm thinking airflow, fan curves, and possibly a case not ideal for airflow. More complete specs would help here (case, pics of how things are oriented), but I'm curious, how are you running a Noctua NH-D15 tower air cooler AND an AIO?

Revised, more info

We've gone over all of this already, please read previous replies and you'll get the answers you are looking for. Also OP isn't running both at the same time, they've just tried both the AIO and NH-D15 separately.

If it's a bad sensor it's hard to say, if it's the sensor that directly links to the CPUs throttling capabilities it should however, you would need to hit the temps required for it to start throttling. It has to hit a certain temp to throttle and it sounds like it's shutting down before it hits that temperature. If you have the ability to do so I would test another Ryzen CPU in the system to see if it is working properly, or the 5950x in another system. That would tell you if it is just the CPU or another factor.

[Mr_bubblezz]

im not thinking its airflow as it would go straight to 50c from boot in bios. but does this sound about right when just in desktop idling in its at 55c just typing this post now. and when i took that screen shot it spiked to 63c as im sitting here typing away

im going to get a another CPU here soon and see if it has the same issues ill post back my findings
