Hi,

When i use speedfan to control my cpu fan (4 pin header) i cant stop the fan . When i set it to 0% it is still 1200 rpm and when it is set to 100% it well be around 1900 rpm. I tried to plug the fan in the 3 pin header and then i can control the whole speed but the fan will become noisier.
The problem with above is that i am about to buy a new fan and i have to control it with the cpu fan header but i want the ability to control it totaly with speedfan. So is there a ability to have full control via the 4 pin header ( with full i mean 0%= 0 rpm and 100% = max)

Yes i searched the bios , there is only a enable/disable function nothing more.

Sorry if your eyes burn after reading this english , i talk native dutch.
