I dont know and why my GPU XFX 4870 are getting the temp all the way up to 100'C++ .. The temp doesnt effect my CPU which is 40'C and below.. Even in the idle state my GPU are 100'C++ .. Is there anything to be suspect the cause of it ? Oh and also my room got aircond..
p/s : it keep piss me off when the pc are shuting down all out of sudden and frequently !!.. Maybe you guys can help me what is the problem actually ? The gpu fan are working 100%
Step that i have done :
1. Clean the dust. Failed
2. Update latest driver. Failed
3. Apply new thermal paste. Failed
4. Blow direct fan/aircond to chasis. Failed.
since you already reapplied thermal paste and verified fans are indeed working, I can only think in the chance that your gpu voltage somehow got raised? thus getting those temps due to an elevated voltage.
If you can manage to get into windows check your gpu voltage with gpu-z, if that's the case I think you can change it with msi afterburner, although flashing your gpu BIOS might be the best way to do it.
Hopefully someone with more experience flashing gpu BIOS jump in to help.
I'm actually surprised that you actually hit 112 on idle with fans working. Are you sure its actually sensing the temperature right? What I mean is, actually touch the plastic shroud to just get a feeling of how hot it is, chances are it might actually be a sensor going kablooie.
Bro JJ1217, i already touch the whole GPU after it shutdown itself, yes it is hot just like how 100++'C should be.. Even the plastic part that around the fan are also damn hot.. And to answer your question YES i think so it read my temp right, bocz the temp are same in either HWMonitor / GPU-Z ..
Very strange indeed, It could possibly be due to a bad driver for your graphics card. Try this:
1) Unplug your graphics card
2) Update/downgrade your drivers
3) Install the graphics card
4) Check temps
With the graphics card reaching that temperature with no load on the GPU there is something else that must be generating the excess heat on that card. Maybe a problem with the VRM (i.e. voltage conversion circuit that converts +12V from the power supply unit to the +1.26V that the GPU uses).
