MX5 can't control fans

I have 2 120mm fans plugged into gpo 1 via a 3 pin splitter. It controls those perfectly, however when i plug another 2, via another 3 pin splitter, into gpo 3 it freaks out. The fans on gpo 3 pulse from high to low rpm rapidly and the display goes crazy displaying all kinds of wierd icons and letters. Each fan only draws .30A at full speed, but i only run them 50% max due to noise.

How does it react with only 1 fan plugged into it?

It works fine with just one fan plugged in.

Have you tried adjusting the frequency of each GPO accordingly...? Are you reading RPM...?

Its not plugged in right now as it was pissing me off so bad i had to take it out. Im goin to put it back in for further testing saturday and sunday.

All i know is it worked fine, controled rpm's fine with 2 120mm fans goin into one header. Then as soon as i put another 2 fans goin into another header the display freaked out displaying wierd symbols then the fans pulsed rapidly and i couldnt control them even when i adjusted the rpms.

After a clean install of windows and lcdc its working, atleast for now. I have 2 120mm fans in header 1 and 4 80mm and one 120mm in header 2, and i have control of them.

Glad to hear it works,

. I hope it continues working for you. If you have any other questions, you can always ask.
