Ok here is what I have it is an IBM Netvisa Overview (United States and Canada) - NetVista 8307 General Information System board/Form factor * Micro ATX / Microtower (4x5) Processor: Intel Pentium 4 with integrated L2 cache * 400MHz or 533MHz system bus Cache : 256KB cache or 512KB on-die L2 advanced transfer cache Chipsets : Intel 845G chipset Memory 266MHz DDR (Double Data Rate) RAM * 2 DIMM sockets (1 open) * 2 - 184-pin DIMMs * Supports a maximum memory up to 2GB * ECC not supported I am attempting to see if this computer is functioning. The computer has 2 fans one for the cpu of course and one for the chassic. When the unit is turned on both fans run during the bios but once WinXp starts up the fans go off. I have not stress the cpu any but even after a while the heatsink is still cool to the touch and the fan has not come on. The room temperature is about 65 F (basement). Is it possible the unit is running so cool that it does not need the fan? Never say Never Romeo Void Firefox 2.0.0.16 A Safer Browser Thunderbird 2.0.0.16

Yeah if you want to go the passive cooling route. http://www.xoxide.com/thermalright-... If it's broke, then blow that sucka up!

"I am attempting to see if this computer is functioning." Then, "but once WinXp starts up the fans go off." Tells me the machine is, in fact, functioning.

Can you see the fan running? Maybe it's running at a lower speed so it is not making much noise.
