my hp pc comes stock with amd fx-6100 and, instead of amd mounting brackets, it uses intel lga 1155 mounting setup for the cpu cooler. it comes stock with CM12V from Cooler Master. it uses mounting screws instead of push pins to mount the cooler to the motherboard. i want to upgrade from fx-6100 t0 fx-8150(the motherboard is rated for the cpu) and i've tried a cooler with the push pin setup but 1) it was to tight of fit to get my hands in there and 2) the pins themselves just weren't going into the holes, so the mobo wasn't having it. what cooler do you guys recommend i go with? i'm not overclocking the cpu.
