I too think its my GPU. I have tested it without the computer cover panel thingy and the temperature lowered a bit but i dont want to use my computer everyday without it
Did you OC and add the GPU at the same time? Or did you OC your CPU and THEN add your GPU? If you did them at the same time, yeah it's definitely your CPU. if not, then it's probably the GPU choking the air supply to the CPU.
