Connecting Case Fans to the Motherboard

Postby flyflyflyaway » Wed Jan 12, 2005 9:51 pm

I have recently purchased two case fans with the thermal sensors. My question is where do i plug the fans in? each fan has two wires, one for power, one for the thermal sensor. On the motherboard (Asus A8V) i see two matching plugs. One says PWR_FAN and the says CHA_FAN (chasis fan?). I have 4 ports to plug into these two slots. I can use a splitter for the power, but what about the sensor? Is the sensor plugged into CHA_FAN?

Any help would be appreciated,
Thanks! ;)

Your right about the it meaning Chassis fan. And I know that that Asus is supposedly one kick @$$ mobo too...  ;D But i don't know about the sensor. Perhaps you can only have the 2 sensors. Can the BIOS display more values? Or have you got one of those fancy fan control units? I shouldnt mind one of them!!

I never looked into doing this on my mobo.  I think I may need one of those controllers.  I just plugged all 5 of my fans straight into the PSU and they run full whack all the time.  Mine isn't the quietes of systems, though it gives me the perfect excuse to crank up the volume  ;D

Ill consider plugging them directly into the power supply. This should free up the sensor port on the motherboard (if i can figure out which one it is). I dont nessasarilly want to buy a fan contoller, so ill read up and try to figure it out.

Where do the fans plug into on the PSU?

thanks!

Well I cant help you but a half tip of advice: Be very careful with splitters.. if you buy a Vantec tornado and somehow hook it to your mobo it will fry that fan jack and possibly the whole mobo in the blink of an eye. Those things can only supply so much voltage and the reason why I say its a half tip is because I dont know what volatage the mobo starts to fry etc... so be careful about that, I am like Gixer though, I have my Vantec 80 mm Tornado as exhaust fan, a slower intake, another 1 or is it 2 "regualar" case fans blowing up from the bottom of the case, and of course my CPU and video card fan all running as fast as they can go... You think your computers noisy Gixer wait till ya hear myne

You think fans are loud. The compressor on my vapochill makes even the loudest fan sound mute. As for fans, I just connect all my fans directly to the powersupply and let them whir at full blast. It doesn't matter as I can't hear them anyway.

Thanks, ill be careful. I think i might plug the fans into the motherboard and the sensors into the motherboard. I dont see why the fan company just put all three pins on one connector. Shouldnt be too much of a hassle though. Any really sure of how im supposed to plug the fans in?

Thanks

I got adapters with my fans  ;D They can plug into either that way.
