My desktop PC of roughly 5 years had been running flawlessly up until a couple of days ago, when I noticed that upon loading up my usual PC games, the fans of my computer kick in at a noticeably faster speed than before, getting progressively faster until they sound as though they're at maximum speed. I initially suspected that a software update related to my PC games could be the culprit, however another day onward, the fans started kicking in noticeably loudly and quickly even when running simple, undemanding applications. Today, the computer actually had to shut down due to "a thermal event", as quoted by the warning message presented upon restart.
I decided to run an application called Core Temp. At the time of this post, each of the four cores of my CPU are reporting temperatures around 100 degrees celcius, however neither of the cores have a load of any greater than 30%.
What could have happened here; is it likely due be a heatsink issue? My CPU is the Intel Core 2 Extreme Q6800. My room is by no means warm, and there isn't a single thing that appears to be obstructing the vents of my PC.
I welcome your opinions and advice with great appreciation!
Yeah need to pull the heatsink off and inspect it. It could be clogged fins, which would inhibit airflow which might explain the ramp up of the fans. It could be the heatsink has somehow come unsecure from the motherboard.
Either way you need to open it up and look. Also recommend picking up a new HSF possibly? Usually run $30 ish
Make sure you have thermal paste on hand for re-application
Nedal0 the OP already stated he is operating at 30% on the CPU cores. But regardless, his CPU should be able to run at 100% for hours and not reach those temps. There is a physical problem with the Heatsink/Fan.
