Simple Mod to increase your fan speed

post #1 of 13
Thread Starter 
Hello.Well all you do is take the red and black wire, expose the wire then find one of ur 4 pin power connectors and insert the black in to a black socket, and a yellow into a yellow socket. When you push it in, it should get to a point were it just sticks.

I don't get it. All you're doing is forcing full speed through the 12v line. Any molex fan will do this all on its own anyway. And 3 pin fans do the exact same unless you've got Cool N' Quiet (or Intel's equivilant) enabled. All this mod does is strip the connector off the end of your fans.

ok, get two fans. Put one attached to a black and red, and the other to yellow and black, feel with your hands and you will see a clear difference in airflow. Also you maybe be able to visibly see the one with the yellow and black is spinning faster. I did this exactly, and saw the difference.:swearing:

That's because your red power line is the 5v line, and the yellow is your 12v line. Both blacks are just gounds.

And what I'm saying is that ANY 4 pin (molex connector) will be running off the 12v line ANYWAY. Same thing with 3 pin fans...but you just have to turn off the fan speed stuff in BIOS to get them to spin full speed.

I know exactly what you're saying. And also, a LOT of fans won't even run off 5v (the red wire)....hence why 99.99% of the fans out there WILL run off the 12v line anyway (yellow).

Hope this helps .

Yeah dude, the 3-pin connectors from the motherboard are 12v too, they should run the fans the same speed. Running the fans parallel also delivers 12v, so I don't know why you would want to ruin your fan connectors/leads.

you should be a lilttle more clearer in explaining it tho

Exactly my point! Thanks, lol.

Now I HAVE in fact "ruined" some fan connectors myself because I had fans that were 3 pin and I wanted molex, or vice versa. But NEVER just so I could run them at "full speed", since they always do anyway...unless software is turning them down.

Even if this did work, I don't understand why you would run your fan faster than "full" anyway. Higher rated fans have different motors and require different current. I'm sure you run a good risk of damaging your fans by making them spin faster than they should(correct me if I'm wrong). Why not just buy a faster fan?

I've actually ruined my fan connector once when my fan was spinning the wrong direction. Simple fix though, reverse the red and black wires back to where they need to connect.
