FX 8350 Suddenly Running Hot: Why? Please help

post #1 of 16
Thread Starter 
I recently started having problems with my CPU running hot. It used to idle at around 20C, and now idles at around 40C. Even doing moderate gaming, AMD Overdrive and CPUID HWMonitor show my temperature running into the high 60s. The only thing that's changed recently is that I installed two new hard drives. Everything else the same. Is it possible that my liquid cooler or thermal paste suddenly went south? Looking for ideas on where to start to fix this. Built this rig last November, never had a problem until this week, and noticed it because I had only ever heard the radiator fans kick into high gear a few times while stress testing. Any help would be appreciated, thanks!

Have you checked the radiator for dust? It could be that dust has built up and is making the airflow bad through the rad. You could try reapplying the thermal paste too, I don't think it would randomly go bad.

Yes, I did check for dust. I actually cleaned the case grilles on top and front too. I can see through the radiator into the case; its virtually dust free. I thought about obstructed airflow too, but the hard drives I installed are actually on the bottom of the case and the side (the 3.5" is sitting in the bottom slot in the drive rack and the 2.5" is against the back side wall of the case out of the way of the fans). I would have thought that that liquid cooler would have been more than sufficient, and it's worked fine for months until last week. I was hoping I wouldn't have to go through an reapply thermal paste.

Bad pump or check the water block mounts is my guess.

How do I check the water block mounts? I've never taken one of these things apart. It's a Corsair 100i GTX.

Do you have Corsiar Link installed? That might give you more information as to what is going on.

Corsair Link is showing me the same temperature information as the other two programs, except it's showing my fan rpms too.....one is slower than the other. Is that normal? Shouldn't they both be running at the same speed? I'm going to power down and check for obstructions now.

The fan showing 1680 RPM is one of the fans blowing through the radiator. There should be two fans on an H100i. The 2700 RPM icon is the pump speed, which looks normal. Like the others say; looks like you need to remount the waterblock and thermal paste.

I'm running my 8350 on 1.4125v at 4.6GHz and it idles at 28C with an H80i.

I think I figured it out. This motherboard has some sort of automatic turbo boost option thing that I turned on by accident. Stupid of me. I noticed the voltage was bumped up to 1.4125. Which given that info puts my idle temp right in line with yours, Dead Meat. That being said, I guess now I can see how far I can overclock it. You've got yours at 4.6 with that voltage. I might try to work my way up there. Any experience with this motherboard: ASRock ASRock Fatal1ty Gaming Fatal1ty 990FX Killer AM3+/AM3 AMD 990FX + AMD SB950 SATA 6Gb/s USB 3.0 ATX ???

From the experiences of others one can say that it is a good board until it gets overclocked. Then it overheats quickly and has a short life span. Fans on the VRMs and the back of the CPU socket are needed to help cool it.
