Hey, i recently got a Gigabyte Geforce 8600GT which to my misfortune does not have a fan and relies on my case's airflow and has a HUGE heatsink. Pic: http://my.ocworkbench.com/2007/gigabyte/GV-NX86T256D/g2.htm At idle the temp is at 53C and when im playing something the temp jumps up to 80-86 after around 30-40 minutes. My computer has 1 intake fan and 1 exhaust fan. I want to add a 120mm fan to a pci slot or to the small pci-e slot to blow air onto the GPU, i heard that the temps will go down by 30-40C which sounds pretty great to me. Now my problem is i have no experience at all with modding and i would not know how to set a fan horizontally to blow air up onto the heatsink. I dont even know how to connect a fan to the motherboard or PSU or where ever it needs to go. If someone could tell me how this is done i would appreciate it alot. Thanks to all and any help or advice. Or maybe there is a fan which connects directly to a pci slot and i could have control over it with some software?
