how to make cpu fan always run at max speed

[scrubman]

i have an Arctic Cooling super silent pro and i think i just want to make this thing run at max speed constantly... is there a way to do that with multi speed fans contolled by a heat sensor? i can see the sensor in the fins of the heatsink... thanks for any help!

1) Get a 3-pin to 4-pin adapter.

2) Plug the fan into the 3-pin side.

3) Plug the 4-pin side into one of the regular 12v HD/CD-ROM 4-pin power plugs.

*If your power supply comes with 4-pin "Fan Only" plugs, don't use them. They are also sensor controlled. But the 4-pin plugs for the IDE devices are a full 12v and that should work fine.

I had the same dilemma trying to keep my coolermaster LED fans lit without pulsating (they pulsate when fan speeds are less than 100% throttle). The only way to do that was to keep them at full blast constantly, so this was the workaround that worked for me.

Good luck.

thank you so much!! i will see if that works for me as soon as i get my new mobo and cpu... i burned them both up just from changing the heatsink/fan... all i wanted was to make it a little bit quieter... im not exactly sure how that happened but i think that the new heatsink wasnt seated 100% on the cpu core... owell, first time for everything...

You're welcome. Hope it works out for ya.

Keep me posted.

i dont think that will help because the fan speed is controlled by the heat sensor, not the voltage from the power connector... i was thinking what would happen if i cut the sensor off and shorted the 2 wires together??

No, I'm saying bypass all the heat sensor sockets on the motherboard altogether.

Just plug the fans directly into the 12v 4-pin plugs wired directly to the power supply.

You know, the plugs you would normally use to power your IDE devices. Just get a bunch of Y-splitters and hook up all the fans to one 12v 4-pin plug.

whats a heat sensor socket on the motherboard??

anyway, i cut the sensor off the fan and shorted the 2 wires... it runs full speed and is still pretty quiet!!

thanks for you help anyway!

Oh, ok then. Rock on!

By heat sensor socket, I meant the actual 3-pin fan sockets built into the mobo. They're usually sensor-controlled.

oh, i didnt think they were...

thanks..
