I need help solving my cpu overheating problem.
Pretty much all games, and especially older ones, is overheating my cpu. I have concluded that the problem is the cpu fan which, for some reason, is always running at a constant 1000 rpm.
The result is that games are able to run for about 15 minutes (with lowest gfx settings) before the cpu reaches critical temperature and computer shuts down. I'm using SpeedFan to monitor the temperatures. GPU is always around 77C while the CPU (Core 0 and Core1) goes from 40C to 90+ (higher than 89 is represented by -36C).
After som research it _should_ be possible to increase the rpm of the fan manually (to like, say, 2200 rpm) either by OS software or in BIOS settings. I've tried both without success. I also tried switching the fan cord connector (3-pinned, 3 colors) from "CPU FAN" to "FAN 2" on motherboard, resulting in an even lower rpm (700).
In BIOS there are 2 options of relevance in the PC Health section:
Smart FAN Control Method: Auto / Intel(R) QST / Legacy / Disabled
Smart FAN Control Mode: Auto / Voltage / PWM
I've tried every combination of those without any speed increase.
In SpeedFan some voltages are also shown:
VCore1: 1,17V
VCore2: 1,89V
+3.3V: 3,34V
+5V: 4,97V
+12V: 1,66V
-12V: -16,97V
-5V: -6,26V
+5V: 5,30V
That +12V seems, for one, a bit weird at a glance. Can the problem be any of those? And if so, how do I manually change them?
Any help would be of greatest appreciation.
