My desktop PC (built in Dec 2005) running Windows XP Pro SP3 is showing a
warning message at boot up: CHA1 Fan fail or speed too low. I can hit F1 to
ignore it or delete key to enter the setup where there are 3 options for fan
speed. I've tried all those speeds (not sure which speed should be selected but
I'm guessing that a problem exists for sure after the warning comes on at the
lowest speed selected). In checking the build on this unit they've installed a
Power Supply 400W ATX Dual Fan with an Asus A8N-SLI Deluxe motherboard. Can I
replace the fan with any 400 Watt Power Supply? I've noticed that Amazon has
them at various prices. Thanks for your help.
