Due to the size and the mounting direction of the cooler rises above the RAM slots. Only the outermost bolt can therefore be operated with heatsink. Buyer of RAM ensure that the heat sink can be removed. For Intel, the fan is apparently different installed, so there is no such problem.
CPU is idle about 30 ° and 50 ° at full load not, and I have the GPU easily tuned.
But the best thing is: I can hear the fans are not.
