512 Rear chassis fan not detected

HP Recommended
Hp 8200 SFF
Microsoft Windows 10 (64-bit)



I recently upgraded my HP 8000 with an HP 8200 motherboard. I installed everything, but now the same message comes up everytime I boot it. 512 - Rear chassis fan not detected. I tried to look into the BIOS but couldn't nfind anything to disable the rear fan. When I connected an other fan ( from another 8000) to the rear fan connector it worked fine. The only problem is that there's no space in the SFF to mount another fan.

Please help me find a solution.

For $9 US, try this "2-inch" fan:

Maybe, you can fit it somewhere inside ???


Or, I have seen a machinist who cut a circular hole in the side-panel of his computer, and screw-mounted a fan on the inside of the panel, to exhaust more air from the case. :OpenSmile:

He also mounted a screen, to protect any "finger-poking" from hitting the fan's blades.

Such an arrangement takes up extremely little space "inside" the case.
