My current system is an xps720. The CPU is a Q6600, however the issue I'm having is the cpu runs constantly at 100%, resulting in noise even while idle. Please help.. :??:

There should be a setting in the BIOS to change that setting. Was it always like that?

I only notice it recently when I moved to my new home.

If you're absolutely sure that it's the CPU fan, then check your BIOS settings

As GhislainG said, check the BIOS setting, and while you are at it, check the CPU temp in BIOS, you might have knocked the case and the CPU cooler have become lose.

Haven't seen any option for fan settings in the Bios.

lothdk has a good point about the HSF being loose after moving the PC.

Speedfan reports my CPU at these temps:

Core 0: 26C
Core 1: 26C
Core 2: 21C
Core 3: 22C

Are there any tutorials to check the HSF?

Where is the fan plugged in ? If it is on the CPU header of the MoBo, there should be a way to control via BIOS.....If plugged in to PWR, CHA or OPT fan headers, or connected to Molex, it will likely run full speed.

Sorry for not responding earlier JackNaylorPC, I've been searching for a picture of my system board to share with you guys to help direct me in what I should be looking for.

I installed Ntune and it shows my fan at 13% in auto, but when I go into direct fan control and set the cpu fan to 6%(lowest it allows) the noise while lower then the 13% is still noticeable. :??:

With the fan running at 13/6% in Ntune, does whatever other application you used to find the initial fan speed still report 100%?

Was your case previously out in the open, and now in a (more) closed enviroment like under a desk, up against a wall, or even something like placing it on a wooden floor can have an impact on the noise compared to on a carpet.

Ntunes so far was the only application that allow me to edit the fan speed, while others were locked with automatic fan control showing 100% so I figure it was at that speed, please forgive me.

My case use to be out in the open on a desk, now it is currently on the floor at the side of my new desk.
