thelonerangers :
im looking to bring the temps down for my 8800 gts, the temp idles at like 140 F and when playing games goes upto maybe 160 F. What are my options for an aftermarket air cooler for this card or is there a way to upgrade just the fan on the stock cooler? any help would be greatly appreciated.
First of all, your temparatures are not out of line. 60c while idling, and 71c under load is normal. The cards run hot, and they are designed to do so.
On my previous PC, I had a 8800GTS and wanted to improve the cooling, both with the vga card and the cpu.
The case had adequate ventilation.
The stock cooler on the 8800GTS is actually very good. It sends most of the hot vga air out the back of the case.
There are, however four slits in the card through which some hot air escapes back into the case. This heats up the intake cooling air to both the vga card and the cpu, resulting in an increase in temperatures until a steady state is reached.
What I did was very simple and effective. I installed a slot cooler directly under the 8800GTS. This picked up the hot air escaping the vga card and sent it out the back of the case. The net result was about a 5c drop in both vga temperatures and cpu temperatures.
I used this unit which has a speed control knob, allowing you to control the fan speed:

At $6, I would try it first. Most oem 8800 coolers do a good job of getting heat from the vga chips, but they don't finish the job because the heat is just dumped back into the case.
