Probably buying the ASUS M5A99FX PRO R2.0 and it has a second 4 pin cpu fan header. Where exactly does one usually place the second cpu fan? (Pictures, please, if you have any.) BTW the CPU I bought is the 8350 and the seller is throwing in a Water Cooler for the CPU as well.. Just want to make sure I use all available options provided by all those fan headers. Thanks!
