Title: Can't manage to manual control the speed of my fans :(
Post by: Korah on February 02, 2010, 04:31:00 pm

I have the Gigabyte Ga-p55-us3l rev.1.0 motherboard and I've connected 3 fans on it. 1 is my cpu fan 4pin and 2 case fans 3pin.
The cpu fan I can control it with Easy Tune 6 but the other 2 I cannot :(.
The question is: How can I control the other 2 (without using a fan controler)? Any software available?
BTW Speedfan doesnt work :(

Ty


Edit: I had an older mobo GA-8I945GMF and I could control the 2(cpu and system) fans with speedfan by disabling smart fan control from BIOS.

use 4-pin fan for system fan to be controlled.
enable system smart fan in bios (pc health status menu), if can't find then press ctrl+f1.
use newest bios and newest easytune also, both can be downloaded from giga site

As Kangoo says you need to have a four pin fan to be able to control the speed of it. The extra pins apart form the positive and negative are the sensor and the controller.

Well yes there is positive, negative, tachometer to report speed and if a forth pin is present this is used for Pulse Width Modulation:

You are best off leaving the CPU fan to the system, it knows much better than you what speed your fan needs to run at based on temperature.

A decent fan controller isn't going to cost much at all, you can buy many of them very cheaply and most are good quality, I would encourage you to look into buying one if you wish to tone down you fans a little.

I have used many, and find them all the be good. My current one is fantastic, this is it:

You should be able to buy a decent unit for as little as $20 US dollars if you look around.
