right just noticed something somewhat worrying, the idle temperature of GPU is currently 80.0*C according to GPU-Z, fan speed is 40% and GPU load is 0%, should i be concerned about this?![]()
Yes it is too high. It sounds to me as if the HSF is full of dust.
Strip off the HSF and clean out both heatsinks, they will be full of crud.
Re-apply new TIM and then re-assemble. You should then be getting idle temps between 40c and 45c.
