The CPU fan goes noticeably faster than it should!
Basically I have an old Dell GX280 full-size desktop computer (it's not the one in the picture on this site. It's one which is made to sit up and not lay on it's side), and recently I had bought a replacement motherboard for it since the old one's capacitors were bulged and it wouldn't boot, and the fan would go extremely fast. After installing the new motherboard, I noticed the computer CPU fan is going rather fast, and lots of air is being pushed out, and this is when it's idle and not doing much of anything. I don't have a hard drive in it right now, but I boot Lubuntu 16.04 from a live USB to use it. I've looked high and low on the internet for an answer, yet just about every person describes their problem as being "Extremely fast and loud fan, and no boot". Mine boots, but goes faster than it should. Any ideas? Oh, and this isn't my main computer. It's just a spare which I'd like to make use of.
