New fan but loud loud noise

  1. Hi everybody, I would like some help!

    I recently bought a new fan to help with cooling as the summer approaches. My new fan replaces my old chassis fan but is plugged in slightly differently as it is plugged into the 3 pin mother board connector (the old one was plugged into the molex and is now positioned as an intake fan at the front).

    My problem is that since I've installed the new fan my computer is actually louder than before, Everest tells me that the revs for the new fan are 5114 rpm as I type this so it's clearly working too hard. I think it's working too hard because my processor fan is only idling by comparison at 1705 rpm. Which temperature does the chassis fan use to control it's speed and why has my CPU fan suddenly become lazy since I installed the new fan? Is there anything I can do to make the CPU fan work harder and take some of the burden off of the chassis fan?

    Many thanks for any help!

    Thank you very much - this was exactly what I was looking for! Now my computer no longer sounds like it's trying to take off!
