Hey bombers, I know tested's a bit better for this sort of thing--but those forums get even less traffic these days than they used to. Hoping I can get some help.
I built my PC about 11 months ago, and it's been working fine with no problems. As of this morning, the CPU starting running at a significantly higher temperature--triggering automatic shutdowns. I was generally running at 50-65C, and now at 85-90C. I dust and clean my computer every few months, the heatsink and paste were correctly applied at its building and remain securely in place. I was able to keep the computer on long enough to enter into the BIOS and change the power plan to "power saver" and to turn off two cores of my i5 2500. This has brought down the temperatures to about 60-70C, which is a safe temperature and all...but still high even for when the power plan was on "performance" and all four cores were whirring.
Any ideas as to why my CPU is suddenly running much hotter and how I can correct it? It's been just under a year with this pc, is it already time to drop $30 or so on a good heatsink and thermal paste?
For reference, here's my build...
i5-2500, ASUS P8H61-M, XFX Radeon 6770, 4 GB G.SKILL Ripjaws ddr3 RAM, EarthWatts EA650 650w PSU, Samsung Spinpoint 1TB HDD, boring case, boring optical drive, Windows 7 Home Premium 64-bit
Thanks for any help!
