1. First of all, I need to know if cpu corrosion is something that actually occurs. I heard it happens when your cpu runs hotter than it should.
2. Second, How can i keep my cpu running cooler? My i7-860 is running at 50c at 20% and it runs at 70c when prime 95 is running. Is this ok? or should i buy new thermal grease because i had to take off my heatsink once because it wasn't put on correctly the first time.
