Some CPU issues, are there solutions?

[DarkEnergy]

So, I always thought I had lost the silicon lottery because I couldn't ever overclock my CPU without temperature problems. Then I realized it was a socket temp problem, not a CPU temp problem. So I took off the back panel of the case, made a paper fan and waved at it. Temperatures fell, 70,69,68,67......Down to 59!!! Is there any way to mount a fan on the back of the mobo? Also, a real problem I noticed while typing this. I was using P95 to stress test the CPU for about 10 minutes. It's currently not overclocked, on stock. The issue is that 2 of the cores have already stopped because they failed the test. This is without overclocking. Do I have a bigger problem here? I also noticed that the CPU only goes up to 99% load in task manager. Never hits 100%

That's very odd. What CPU cooler are you using and how long ago did you apply new thermal paste?

 

Boards/cases aren't built to have fans fitted to the back, but if you have a massive case then you could probably manage it with some creative DIY-work.

Some older cases had fan mounts there (like the CoolerMaster 690 I and II, i think the III no longer has it). You can make up your own ghetto-mounting, although probably you won't be able to close the side panel any more.

 

Which CPU, motherboard, and CPU cooler are you using? In my experience, high socket temps with moderate core/package temps could imply overheating VRMs. You can check if placing the fan on top of the VRM heatsink, or pointed to the back of the VRMs (to the right of the socket in that picture) has a similar effect. If it does, you can strap a fan to the VRM heatsink.

It's a 212 EVO and I applied Arctic Silver 5 about a year ago. If I were to put a fan on the back I would just leave the case window off.

I think the temperature probably only fell because you opened the side panel and not because you waving air at it.
I'd suggest to replace the thermal paste and either leave the sidepanel off or you could drill some holes into it

It's in my signature. The heatsink is huge on the m5a99fx so I'm surprised it would be having issues.

It was definitely from waving air on it. I've kept it off long enough for the temperature to even off and when I start waving air on it it drops the temps.

Okay.
Well maybe you can find a heatsink which is thin enough to put on the back of the backplate.
But I'm not sure if that would,work as the backplate is quite uneven.

If there is enough space, you could simply drill a few holes and put a thin 10-15mm fan inbetween your backplate and sidepanel.
Then drill some holes into the sidepanel to let air move through it.

Other than that I don't have an idea.

id sat most likely your culprit is old thermal paste. AMD CPUs tend to run hotter and i doubt that your socket temps are any issue. Just try and reapply your thermal compound on the CPU and reseat the heatsink.

There are some cases with bottom socket cooling. And in the past, some boards have a special layer pcb that automatically dissipates heat from the bottom of the cpu socket, without the need for a cooler.

You definitely shouldn't have this problem at stock speeds.

 

When overclocking, though, I wouldn't be so sure: I did benefit quite a bit by putting a fan on a 990FX Sabertooth VRM heatsink (on the ASrock 970 performance it was more than convenient: it was absoltutely necessary. But your board should be closer to the Sabertooth).

In any case, always better to check, know, and discard than to conjecture

I think I found the issue and why it was doing that. I had enabled "Optimal" setting on the asus bios. Apparently that somewhat overclocked the CPU but underclocked the memory (what a retarded setting) and for some reason task manager didn't show that.
