Thanks, theveterans. I Applied new thermal paste and temps started from fresh boot at 50C idle, but it still climbs slowly, steadily toward 80C. Takes a while longer, but the fan never hits full speed. if I put any load on the GPU, it goes up quickly and doesn't cool off. Thermal paste is def. working as it should. when i took off the bottom cover to check, the heatsink was very hot all the way to the fan and the blades in front of the fan were hot. Might be the GPU is going bad? and overheating? not sure....

The reason I ask is because when a fan has something like a bearing going bad it will take more amps/volts to start it to turn and until your system gets hot it will not get the required amp/volt to start it up. It takes many more amps/volts to start a fan than it does to keep it running.
I would replace the thermal paste and the fan. Both are cheep.
Thanks Layback, this is something else that I was unsure of. I haven't done anything to the BIOS, but I will reset and see if it starts to spin up properly. also for the fan going bad, I didn't want to purchase a new fan if mine is physically ok and then install it to see the same issue, but I will look into this as an option if further investigation goes no where. Before replacing fan, I will "cut blue wire" to see if the fan can run at full speed.
I also tried reinstalling the NVidia drivers
, but that didn't seem to help....will give the BIOS a shot...
Also, found out the GPU fan speed is listed as CPU fan speed due to there being only one fan.
Still in the process of moving, but had this happen last night while away from home. luckily there was a compusa nearby that I could get thermal paste from. I might not get back to this project till next tuesday or wednesday....
Thanks for all the good info guys
