I have this computer that I did assemple, since 2013.
It is an i5 4690 @ 3.50 (not overclocked; I use the standard ASUS OC setup, which is set in the motherboard automatically). The video card is a GTX 9700, also from Asus. I did buy all from the same brand to minimize issues.
Since few weeks ago; I did notice that the computer fan would crank pretty hard; it is hot here, but has been hot also in the past 3 years after all. The GPU stay at idle at 39C, with fan at max, the CPU is at 40C and the mobo at 39C. I use the standard CPU cooler that came with the CPU, and the case has a front fan.
I did play any sort of game, cranking up the settings until the computer would scream; and never had issues (Guild wars 2, star citizen, Elite dangerous, Black desert online, crysis 2, among the ones that I play often). But recently, I did notice that the CPU overheat quite a lot, going at 70C and beyond; in some case the game crash; in other instance teh computer just forcefully reboot.
Do I have to replace the CPU fan? Thermal paste only? Is this a software issue? I do recall that I did update Windows 10, few weeks ago, and the Nvidia drivers, via Geforce experience, which is when the issue started.
Is there anything in the windows logs that would show software issues? Before take apart the CPU fan, I want to try anything less radical first.
I did remove the CPU cooler, nothing out of the ordinary, beside the paste that was quite dry; so I did clean up both the CPU and the fan surface; and re-applied Artic Silver 5. The temperature seems to be more stable, but still the CPU is going above 73; although now it just cause the game to hang; the computer does not shut down by itself.
This is the first time that I see something similar; I've been in the same place for 12 years; and none of my computers ever did overheat; staying on night and day. Could it be that the CPU is damaged? Maybe I am still under Intel Warranty.
