Title: Maximum draw on mobo CPU fan controller
Post by: auric on July 08, 2010, 03:56:14 pm
What's the maximum draw I can place on the fan controller of the GA-Ex58-ud3r without frying it?  I can't find any mention of it in the manual.

With these new 2x copper motherboards as long as you don't want to try and run your desk fan off it there shouldn't be a problem.
I have just checked all the available data and can't find any specific figures on this.

I've read a lot of warnings that especially 38mm fans shouldn't be run off of your motherboard, and there are countless stories of mobo's being fried.  Are you saying this no longer applies?  Would you risk your own hardware on being right?

38mm? I am running a 200mm fan off mine and a 120mm. ;)

38mm as the thickness.

I really don't know about that although I wouldn't think it would be a problem My 200mm is 30mm thick. I would suggest that you contact technical support and ask them directly. Please let us know their answer.

Just looking at the 38mm Ultra Kaze fan which I take it is similar to what you are referring to. It draws 0.6amps which is not a substantial amount. I wouldn't have thought that this motherboard would have a problem with that.

I'm not sure if 0.6A is the continuous operating current or the starting current. For example, the advertised operating current of Akasa Apache is 330mA, but when I did a test on the fan (supplied it with 12V and monitored the current) the continuous operating current is only 90mA!

I take it that is the start up current that is quoted as it's always much higher than the running current.
