Safe to run Delta Fans off MOBO fan ports?

post #1 of 12
Thread Starter 
i plan on buyin two of these http://www.newegg.com/Product/Produc...82E16835706032 for my H50 however im concerned two will be overload on the fan controller. they seem nice because ill be able to control them in speed fan since they are pwm what do you guys think, every port on my board will have a 120mm fan attached to it. might just go with 1 tho as the pusher fan so i can generate some more pressure let me know what ya think

Most Mobo's support up to 1 amp per fan header, and this site http://www.heatsinkfactory.com/delta...speed-fan.html says those fans draw ~1.5 Amps, so I wouldn't chance it. You run the risk of burning out your fan controller on your motherboard.

Speedfan's fan speed controls are often unable to control fan speeds.

(say that 5 times fast)

But you can try it anyway.

Only once did I demand more from a motherboard to fan connection a long time ago and fried the connection!

Best to use a fan controller with HP fans.

What is the amperage of your fans?
Type of connector?
I'm surprised and disappointed nobody asked this

EDIT: Figured it out. Most motherboards would be unsafe due to 1.74A/fan requirement. You would need something such as Akasa AK-CB002 for that (a special cable you can't buy at Newegg)
