I'm currently turning an old HP Compaq dc7800 SFF into a "silent" HTPC. To do that, I want to change the chassi fan and the PSU fan to PWM fans from Arctic Cooling, so far so good. I also want to completely remove the CPU fan, which is not needed (The thermally controlled chassi fan blows through a duct on the underclocked E6750 which stays amazingly cool, while the GPU, HD5450, does all the hard work without breaking a sweat
).Now, here's the problem: The BIOS wont boot without all fans being present. How do I fake a fan being present?
All the fan headers are 4-pin PWM sockets. Can I just cut the connector from one of the old fans and place it on the CPU fan socket? Or will I break something?
EDIT: Forgot to mention, I haven't found an option to override the fan check in BIOS control.
My last option is of course to replace the CPU fan as well, but as it's not needed I really don't want to do this...
Any suggestions appreciated!
