Need to find a low-profile CPU cooler that will fit Intel core i3, Gigabyte GA-B85M-DS3H-A, and Apex DM-317-A case...without blocking any RAM or PCIe slots. Was going with Noctua NH-L9x65, but a few on other forums say it is likely too big for the case, or will block slots. I have not been able to find anything smaller. Any suggestions?
