I built my first computer (specs below) just over a year ago, everything was running fine until about a month ago when the CPU temperature started going crazy. When the computer was idle it would be at 90+. I've not overclocked it or anything. When it was running well the temp when idle would go between 30-40 then up to 50-70 when running intensive games/apps. I read the temp purely by the digital gauge built in to the motherboard.
- I assumed it was the cooler, so I reapplied paste, same thing. Contacted Corsair for troubleshooting and tried their suggestions, still happened.
- I installed the stock cooler and things got better, however when idle all of a sudden the temp spikes up to 90, it'll stay there for a bit then go back to 30-40. Basically it is all over the place. I can be doing nothing away from my comp, it will be at 35, stay like that for 10 mins, then without even touching it it'll spike to 99, go up and down for about for a varying amount of time, then head back down to the 30s for a while, then start all over again. When I do anything even remotely intensive, like run Hearthstone, GS:GO or Fallout on low settings, it stays between 85-99. It used to not go above 60 when I ran these games on ultra settings
- It is well ventilated.
- I restored all drives to factory settings and reinstalled Windows 10, still happens
So I know it cannot be a cooler issue, right, as I've tried 2 now and it is still happening?
I know it can't be a virus, as I reformatted.
What else can it be?
I'm so broke right now I can't afford to take it a computer shop, but if I can figure out what is going on I should be able to afford to replace the specific part, or maybe it is under warranty.
Any help would be greatly appreciated!
