I decided to upgrade my old Sony VAIO VPCEH2P0E laptop’s Intel i5-2430m processor to a i7-2680qm CPU. This is the best benchmarked CPU supported by the Intel HM65 Express motherboard chipset. The i7-2680qm has 45W TDP (Thermal Design Power) which is higher than the vendor’s 35W TDP. Because of that, I had to upgrade the heatsink too.
