Splitting GPOs?

Post by Xtant »

I know I'm asking a zillion questions but I figure if anyone knows it's going to be you guys. I have a GPU fan thats noisy as hell due to the fact that it runs at 6800rpm or some such number. Can I split one of my high output GPO's to run 2 fans? A case fan and the GPU fan and tie them to the same thermal event and or percentage event?

Hello...

Yes you can run two fans per GPO. A couple things you must remember:
1. Only one of the fans will be able to report RPM.
2. The maximum current per high powered GPO is 1 Amp.
3. To utilize the voltage output of the GPO, ensure your fans are connected in parallel, not series.

It's been forever since I took basic electronics, how do I make sure I'm in parellel and not series.

Probably the easiest way to explain it is do not "daisy chain" the fans, rather have an individual connection to power and ground. :D
