So, I'm doing my first PC build in about 10 years, and I've never installed an after-market heatsink (the kind with the big tower, etc.). I got the tower mounted to the mb and processor fine, but for the life of me, I can't figure out how to attach the fan to the tower. The fan has two arrows at the top that are at right angles, and the fan is supposed to be mounted by two (or four?) high-tension wire clips that slip into the fins on the tower. The instructions are absurdly awful with no clear diagrams. I can't even tell which way the fan is supposed to point, much less how to mount it.
It's a ThermalRight True Spirit 140 ([^]); any tips on installing?
