So I have an older AM2 motherboard. I noticed that it can't power a CPU fan (the fan tries to spin and then stops). Back when it had it's stock CPU fan, the fan would spin up. However, this board is able to start a chassis fan. Why is it that it can't power a CPU fan, but it can power a chassis fan?
Oh right, should've mentioned. I've tried about three different fans, I know it's not the fans because when I used the fans in a different computer, they worked fine, and I know I plugged them in right (How do you manage to improperly plug a CPU fan in? The clips won't even let you do that...)
The motherboard is a factory motherboard from HP. Can't really do anything about fan speeds, and then there's the fact that this AM2 motherboard only has 3-pin fan headers, and I have tried with 4-pin ones as well, and as I said before, I've tried more than one fan, and those fans have worked with other computers. It's not the fan. What I find odd is that any CPU fan that is plugged into the board won't work but if I plug a chassis fan in, it'll work.
