Hi everyone,
I recently upgraded by video card from a radeon 4850 to an nvidia GTX 560. On making this change, my PC began to randomly shutdown, the source of which I quickly identified as the CPU overheating beyond its 'safe' temperatures.
The CPU is an i7 920 c0 stepping in an MSI X58 motherboard.
After some testing back and forth, swapping out the new card and the old one and testing various temperatures, I have the following information:
Old Radeon installed:
Idle GPU temp: ~65 degrees C
Load GPU Temp: ~80 degrees C
Idle CPU temp: ~35 - 40 degrees C
Load CPU Temp ~60 - 70 degrees C
New GTX 560 installed:
Idle GPU Temp: ~20 - 30 degrees C
Load GPU Temp: ~50 - 60 degrees C
Idle CPU Temp: ~50 - 60 degress C, or higher (fluctuates a LOT)
Load CPU Temp: Climbs rapidly upon use of most applications particularly games, caps at around 100 degrees C then the system crashes.
I've been reading forums and doing web reseach trying to find users with similar problems, and I believe I found a few, but for the most part people seem to think that the change is attributable to an overall case temperature change.
My arguments against that would be:
1) Overall case temps causing a 25 degree + swing in CPU tempatures seems pretty extreme.
2) Why would the new GPU running at lower temperatures compared to the old GPU, cause such a huge swing in case temps?
3) The case is a clean and well maintained full tower with 5 correctly configured fans.
Does anyone have any other ideas why this might be happening?
Thanks in advance for any help,
Kind Regards,
