About a year or 2 ago, I had an HP desktop with a propitiatory foxconn motherboard. I ended up replacing it with an ASUS motherboard that had a 4 pin cpu fan slot. However, the cpu fan from the last computer only had room for 3 pins; it still plugged in. However, the second the computer starts up, it's loud as fuck. It's consistent, it's not changing the fan speed based on temperatures indicating it's not a heat issue (at about 32 C temperature it should not be running this fast anyways). I think it has something to do with mixing the 3 pin fan with the 4 pin motherboard clip; it seemed like there was no other way to plug it in, so would I have to invest in a new cpu fan to fix this or was I able to shift it down a pin to fix this?
