AMD FX-8350 Heat Issues! Help!

[DStanizzi]

Hello Everyone. I was wondering if we could use the collective minds of the Linus Tech Tips Forum to help solve my problem. I have a 1 year old system with an AMD-FX8350. I accidentally left my PC on over the long holiday weekend. When I came back it was still on but shortly after waking it it randomly shut off. I tried restarting only to find it shutdown shortly there after. I checked my temperatures only to find that the PC was reaching 75c on the CPU and shutting itself down. I cleared all the dust from my H100i and reapplied new Noctua thermal paste only to have the same issues. Despite having a good cooler , fresh air and new thermal paste why are the temperatures shooting up so high. I also check my CPU usage an its not going over 5%. Any help would be awesome! Thanks.

Is the pump on the H100 working? Can you hear or feel it running?

Another reason for the shutdown could be overheated VRMs

You could try the H100I software and see if the pump is running at full speed and listen to see if it is noisy. Also make sure you are using good fans with some RPM. Putting SP120 QE fans on it is a no go as their speed is limited to 1500rpm.

Thanks for the suggestions guys. The pump is running at normal speed and the fans are running fine. I have been living with this set up for a year. Why is it now giving me troubles?  Also im almost certain the VRMs are fine. I can physically watch the CPU slowly gaining heat till it trips the safety at 75c and the computer turns off.

Take the rad and fans out and see if dust has built up. Try to clean it out with can air/compressed air.

You could also check your BIOS and see at what voltage the motherboard is running your CPU.

Rad is clear and still overheating. What voltage should the FX-8350 run at? Again thanks for the help guys!
