Total of 6 fans, only the ones on the graphic card, CPU, and power supply works. But the power supply fan makes really loud grinding noises and the graphic card above it gets extremely hot. I need to somehow connect the other fans since it seems cyberpower never fully installed them.
Its possible to open a PSU and replace a fan, but should only be done if you REALLY know what your doing. Otherwise you could kill yourself, no joke. A better option might be to pay someone to do it for you, or perhaps just buy a new unit. CM isn't the best out there.
