Fan cooling under GPU

[laijosh]

I just got a Thermaltake PCI cooling fan and I put the fan on top of the GPU so it could cool it down, but then noticed the temps weren't really changing (only went down 2 degrees) that much and the fan was almost touching the video card. I then switched around the alignment of the bracket so I could make it that the fan is blowing air onto the bottom of the GPU to cool it but for some odd reason, my temps went up by more about 6 degrees! Can anyone tell me why this has happened?

Problem with that is better used as an exhaust fan.

i can't cuz only one side of the pci cooler has a vent, other side is just blocked so no way to make it an exhaust, only thing i can do is make air blow toward the gpu, is that bad to do to the bottom of the video card?

The bottom will really not cool anything. You need to get air to the top of the card or back of card where the intake on the cooler is.
