I've just finished a build with a I-5 4679K, a Gigabyte Z87-HD3 and Enermax ETS-T40 and was alarmed to find with no overclock MSI Afterburner is reading 45C at 20% usage, 60-65 at 40% and about 90 at 100. I applied the included thermal paste in a shape between an un-cooked grain of rice and a cooked grain of rice. Anyone know whats going wrong? Could it just be a broken thermostat?
