Linking Aux fan (rad fans) to gpu temp?

Sacrifice · 1 Jul 2015 at 18:37

I have 2 sp120's which are 3-pin, one of them rattles at full rpm as it is horizontal.

I have connected the fans to a 4 pin splitter, and connected that to one the the case fan slots on my mobo.

I have been using speedfan, but I can't seem to get it working, even setting the pwm modes to manual for the chip, the aux fan speed goes to and won't change from 600rpm, and the fan rpm's show up as aux2, yet under fan control only one category, 'aux' is available to select.

Any ideas?

Maybe your chosen motherboard header doesn't allow any form of control.

What splitter are we talking about here?

I can control the fan speed using cpu temp in Ai Suite's fan control, so mobo voltage control is possible, just not linked to gpu temps.

Splitter is a 4 pin to two 4 pin's, where the 3 pins are plugged in with one pin spare

Don't know if it's any good to you but on the bay you can get converters for 3 and 4 pin gpu headers that have normal 3 and 4 pin fan connectors at the other. That means you can run any fan off the original fan header on the gpu and have the gpu control the fan speed as it would with the stock cooler.

Did think about that, although as I am running HG10s, which uses the stock fan, don't think it would help
