I just got a Quad LED 120mm Fan for my case.. It's rated at 4.8w.. I have it plugged into my Chassis Header on the Mobo and for some reason ASUS Probe is going off.. It runs around 1980rpms then spikes to -28783.. Im watching the fan and I see no power failure as it is LED so I would notice the no lights.. It came with a 3p to 4p adapter but I assue this fan isn't drawing too much current to keep it on the Mobo header. Is it possible ASUS Probe is just going fubar'd with the LED's on it?

What should I do?
 
I've heard that some 120mm fan that might require a lot of voltage should not be plugged to the motherboard fan headers.

If it's giving you problems, unplug it and use a fan controller or a regular 4 pin connector from your PSU!
 
Ok.. Guess that's what I'll do.. run it to a 4Pin..

Thanks!

--- UPDATE

That did it.. I noticed a big difference.. LED's are brighter and I feel more air being moved out.. I'm glad you said that.. I would have left it on the Mobo Header and prob ended up shroting out the fan or worse, blowing my mobo..
 
Naw, at 4.3w peak you're using about .35 amps. The chips on the motherboard out headers are usually rated for at LEAST 10amps total. Your board is trying to control the fan speed by varying the voltage to it, reducing noise and performance. I dont know why asus Probe is freaking out...
 
i dont know either.. but since I switched to the PSU plug i've noticed an increase in air sent out and a drop of 2c in total temp.. I'm going to call ASUS tomorrow and find out why this board is throttling.. Its weird, I just got the Centurion 5 case that has the i/o panel in the front and when you plug in your headphones, in normal situations it's suppose to turn off the rear ports.. Yeah this board has a bug ASUS cant seem to fix.. It will keep the rear ports open so you end up with audio out of your headphones and speakers.. They gave me the spill "We're working it out and will update it with a BIOS".. ugh

But none the less I dont care, I would rather my case run cool then have convience of using the mobo header..
