You might try removing the CPU fan, putting the AIO in the CPU fan header, radiator fan in the top fan header, pump fan empty, and then clearing CMOS.   [IMAGE]
Noticed that during extended use I was seeing 95°C + on the cpu ( distributed computing and video encoding ) with the stock water cooling setup. Tried re-applying the thermal paste but didn't notice an improvement, tried moving the 3.5 in drive down to the bottom of the case hoping that would help the stock setup pull more cool air in. Still no dice. Gave up and decided I was putting too much heat into such a wimpy cooler, I needed something with more surface area. Enter the h80iv2 a 49mm thick radiator vs the 23mm thick stock radiator [IMAGE] You can't use the push pull setup that comes with the h80iv2, their isn't enough space, but a single fan on a thicker rad is better than 2 on a thinner one. I intended to use a ML120 Pro fan with the AIO so avoid the bios top fan check issue but was sent 2 regular ML120's. The regular ML120 trip the boot error, but the fans included with the corsair AIO work without tripping anything up during boot. [IMAGE] peak temps at 100% load are sitting around 80°C and due to the corsair fans being quieter, it doesn't sound like a jet engine at full load anymore!
