Chassis fan rpm to slow
I'm using an asus prob fan monitor which tells me my cpu fan speed, power supply fan speed and this chassis fan.
I have a antec super lanboy with 2 120mm fans. Currently the probe is telling me the chassis fan is at 1100 rpm while my power fan and cpu fan are at around 2500rpm. I'm trying to reduce temps so i was wondering how easy is it for me to up the rpm of the chassis fan??? |

(I'm assuming you have an Asus mobo, since you are using Asus probe) Do you have section in your BIOS for Asus Q-Fan? In mine there is, and if I put it onto off then my rpm speeds up. Sorry if you have already tried this.

If you are running the fans at the rated 12v and the motherboard isn't slowing the fans down, there is nothing to do. Remember that a 120mm fan can rotate much slower yet still move more air than an 80mm fan rotating faster.
The only way to get more airflow, without increasing the supply voltage of the fan (not recomended and moderate difficulty as the power supply only goes up to 12v) is to either buy a new fan which operates at a higher speed and has a higher cfm rating, or add additional fan(s). |

Why are you trying to reduce temps? Are you experiencing heat related problems? If not, I wouldn't bother messing with the fans.  Cricket

Turning the Q-Fan feature on can help reduce temps and quiet your PC down. It controls the fan speeds to keep them at the optimum speed for cooling and low noise levels. It worked in mine. I switched it on and my PC got quieter and cooler. Now I have quiet fans so it's not a big deal now.
