CPU Fan speed drastically increased

[Kylell]

Hi everyone.

First off my specs:

Intel Core i7-860 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor BX80605I7860

GIGABYTE GA-P55-USB3 LGA 1156 Intel P55 USB 3.0 ATX Intel Motherboard

COOLER MASTER HAF 932 Black RC-932-KWN3 Black Steel ATX

So here is the scoop. I built this pc myself a few weeks ago and everything went fine. It was quiet, fast and best of all, did not explode when i turned it on. Today I got home from class and turned it on, and everything was fine until about 3-4 seconds after logging into windows. That's when the cpu fan decided it wanted to turn into a 747 engine. I figured I'd reboot, but after several reboots with little or no change I came to these conclusions:

1. The cpu fan speed only increases after logging into windows, and about 4 seconds after that.

2. The fan speed does not slow down, even at 1% cpu usage, the fan is still trying to carry a 747.

3. With SpeedFan, i've detected the cpu fan to be anywhere from 1500-3000 rmp.

Please not, you could barely hear the cpu fan prior to this. I am planning on replacing the stock cpu fan, but I am a student with little to no money, and it will have to wait.

Any help would be appretiated,
thank you.

You might want to consider re-seating the heatsink/fan. It could have easily come loose.

Thanks for the reply,

this however did not fix the issue.

Still no solution, is getting a new heatsink / fan my only real option at this point?
