There is no need for a fan. The fan in the bottom will not help the video card cool — upgrade or no upgrade. The bottom fan only helps cool the processor. None of the bottom fan air gets into the video card's chamber. DO NOT reinstall that fence UNDER ANY CIRCUMSTANCES. Don't say i didn't warn you if you do and the GPU burns up. k On Tuesday, February 4, 2003, at 10:47 AM, Julian Tracy wrote: > on 2/4/03 1:40 PM, Thubten Kunga at Kunga at FutureMedia.org wrote: > >> Remove the fence to let that card run substantially cooler.
