During the build I did have issues the first time I tried to boot. Ended up getting error codes 36 & 10. Turns out I took the ram out and switched slots and then it booted right up. At first I put the stock cpu cooler on and it was horrible. The fan was loud and the temps went up to 55C just installing a few windows updates. A day later I got my Cooler Master Hyper 212 EVO and installed it now CPU at 100% and it still only hits 54C. Advice if installing one of these cpu coolers, If you have this Mother Board then plug the fan power pins in before installing the cooler it's self. It's a pain to do it after with no room to work.
