Case Fans on CPU Fan connector?!

[somerandomguy12]

Hey guys,

 

I have a slight dilemma. My generic Acer Motherboard has no case fan connectors and a CPU fan connector. I would like to get some fans and I was wondering what my options are. One option in particular is using a fan splitter and connecting 2 case fans and one CPU one to the fan connector. Is that safe? All other suggestions are appreciated but I prefer a method that supports changing the fan speed.

What type of PC do you have? I'm assuming a generic Acer mobo means it's not a custom build.

 

If you've got a 3.5" or 5.25" bay available, you might consider a fan controller.

Normal micro ATX but the board was from an old PC. Will the fan controller auto adjust the fan speeds?

There are automatic controllers and manual controllers. You choose.

Do internal 3.5" work?

I guess but there's a display and buttons and knobs and all. If internal is your only option maybe you should look into Aquaero 5. You really don't have a 5.25" bay so you could use something less elaborate like NZXT Sentry?

How about the using a fan splitter in the Cpu fan slot?

every motherboard has different specs for fan current and its very hard to find the specs. I have 3 low power fans on my cpu header

Right okay, I don't trust my generic Acer MB so that would be a no no.

you could take the rating from your current fan and then buy two fans at half that rating. Noctuas are very low mA in comparison to others

There are splitters that use power directly from the PSU. All the fans will run at the same RPM as the CPU fan.

If you do that, the motherboard will adjust both fans according to CPU temps/utilization. So if the intent of this new fan is to cool something other than the CPU, it might not be the optimal choice. But lacking other option, it's definitely better than nothing. I'd still go with a molex adapter instead.

You connect it to the motherboards PWM connector and one of your sata connections (power). You can connect up to 3 4pin fans to it and all will have the same rpm's thanks to PWM. In short..
