Fans on rad seem to power down

post #1 of 6
Thread Starter 
im using a Lian li fan controller (see link below) to control the 2 fans on my rad, i have both fans connected to port 1 on the controller so i have 5 remaining (which is good because i have ordered a xspc rx 360 and i want to push/pull it so need the space, i will use my current rad for the graphics card). when im gaming i obviously put the fans on full blast but every so often i hear the fans quieten for sometimes up to 10 secounds then they go back to normal. i was wondering if anyone has experianced this or knows what it is. my guess is the power to the fans is dipping or something.

maybe your fans are exceeding the wattage rating per channel on your fan controller
you can also try using a multimeter and alligator-clipping it to the + and - lead on the fan controller to check if the voltage is dipping from 12v

yea thats what i was thinking, it has 10w per channel. but this is annoying me because it cost me like £40 so i was expecting it to handle two 1500rpm fans on 1 channel easy

right 1 fan per channel now and seems fine. only thing is i don't think the fan controller blows the fans at max even though the dial is turned to 100%. if i put the fans in cpu fan they are much louder and push alot more air.
This is probably the most stupid question you'll hear but the fan controller has a male and a female molex connection but i only have the female one connected, does it need both connected?

That's not unusual.

Pics show only one male molex. I don't know why you have two, but you only need one for power.
