my GPU temp is running at 60-67c when playing civ 5 when it was only 50-55c and is still happening after i cleaned my computer, my specs are; CPU: intel(R) Core(TM) i3-4130 3.40GHz, RAM: 8GB, GPU: GeForce GTX 750 Ti. im planing to upgrade my CPU to a i5-4690k, will this help, do processors come with better fans or heatsinks to help with circulation or will i need to get new fans?
