[SOLVED] Is it safe to have 3 fans on 1 3-pin sokcet?

[Shanks_1]

Hello everyone,
Motherboard-GA B85-HD3
The motherboard itself has 3 3-pin sockets for fans, however, one of the i cannot control with speedfan for this reason i used splitters to get 6 fans on the remaining 2 3-pin sockets. Since i have done this i noticed that when i start up the pc it shutys down and then restart again. My question is: Is it safe having 2 splitters per socket and having 3 fans on 1 3-pin socket?

It depends on the power draw of the fans... what fans do you have?

Also, does your motherboard manual list the power capacity of the fan headers?

i got 3 of these on 1 socket

Product Size: 120 * 120 * 25mm
Pitch: 10.5cm
Rated voltage: 12V
Current: 0.12A
Input power: 1.44W
Speed: 1200RPM (constant speed)
Air volume: 38CFM
Static pressure: 58Pa
Noise: 19DB
Weight: 130g

how would i check what is the capacity of each fan header?

I hope it's listed in the specifications section of your motherboard manual. It's not shown in the specifications on the Gigabyte web site.

Three of those fans on one header are drawing 360mA or 4.32W, so that's what you're looking for a capacity to handle.

You might try removing one and then two of the fans to see if the shutdown behaviour is altered.

thanks on the manual it just says +12 on the second pin no. ill try by remuving one thanks for the help

Considering Gigabyte aren't helping with decent spec data I'd agree it's safer. Quite a few people have burned out their fan driver by overloading the headers.

You can definitely run two of the fans (or even all three) off a floppy drive molex connector safely. If they're noisy at full speed on 12V an old trick is connect to the 5V wire instead or even between the 5V an 12V wire for 7V. Or if that's a tad to daunting for you just get a fan controller from you favorite computer parts e-tailer.
