140mm fan too noisy

[00stevo]

Hi all,this ones doing my head in.

I bought a 140mm casecom blue led fan,along with the case in my sig.The fan that came with it is fine,it has a 3-pin connection that i plugged into sysfan 1 on the mobo,and im able to reduce its speed in the bios.

The 140mm fan has a 3-pin,and 4-pin molex connection,but no matter which one i use(or even both!) i just cant seem to turn down the rpm.

In the bios it shows how fast sysfan 1 is spinning,but it doesnt recognize the 140mm one.What gives? Is there software i can use to do it,or am i doing something wrong?

You can try plugging your 140mm fan in one of the motherboard's system fan 3 pin connector, like you've been doing, and try downloading THIS. Because you say you can't control in the BIOS is odd though, as long as the fan is legitimately 3 pin and your plugging it into a 3 pin adapter on the motherboard you should be able to manually control it in the BIOS.

The link I gave you is for an application called SpeedFan. SpeedFan allows the user the ability to controls fan while in Windows (instead of the BIOS). Simply lower all the "system fans" that SpeedFan shows to 0 and listen if the fan noise quites down.

 

Let me know if it worked.

Just get a 12v to 7v or 12v to 5v adapter so it will run with less RPM's. It won't work with every fan, but it's worth a shot - though with less RPM's there will be less airflow.
