So im putting together my rig and im using the noctua nh u9b, it has two fans, but my mobo has a cpu fan plug in and a cpu opt.. where do i plug in the other fan?
Heatsinks with 2 fans have a Y Connector that you plug both fan's in to so you only need to connect one fan lead in to the motherboard fan header.
one is each, opt. stands for optional
ok also i just noticed the thermal compound is slightly seaping over the edge of where the cpu and heatsink meet.. is that bad. should i clean it and add less?
well, it's not "good"... I guess define "slightly"... what you don't want is for it to dry, crack off, and work it's way into the pin socket somehow... that is, however, highly unlikely... it's most likely fine and not worth the effort, but for future reference...
a small dot in the center of the CPU the size of a pea will provide enough coverage for the CPU... all you're trying to do with thermal compound is seal the cracks and imperfections in the bond between the cooler and CPU...
ok thanks
