I bought 4 led fans from corsair , 2 of them connect to the psu and run at full speed so the color is bright and smooth , but i cant find an other cable that can connect the other 2 to my psu , so i wonder if i connect them to the mobo if theres any way i can acheive same performance

You connect PWM fans to motherboard fan headers and control them from the BIOS.

 

I have no fans powered straight off the PSU. That's kinda dumb.

Probably gaming or helping technophobes with tech...

There are two ways you can achieve this, from a fan hub or a pwm cable splitter.

 

Fan Hub

1. Plug all your fans inside it.

2. Take the fan hub's 4 pin cable and plug it into your motherboard

3. From there you can easily change the speed of your fans from the bios or your motherboard's software.

 

Cable Splitter

1. Pretty much the same process as the Fan Hub with the exception that you'll be daisy chaining each fans.

Yeah but if you have an older mobo which doesn't have enough fan headers and you dont wanna buy a fan controller, this isn't a bad idea. It's just that they will run 100% the whole time and be loud.

Yes obviously they will . That's why you buy a £3 PWM splitter hub off eBay. Powering off the PSU is dumb.

Yeah I know. I would never do that.

 

I have a fan in my PC that has a really short cable. So I just used cables from my arduino kit and extended them so they reach the fan header.

Yeah I have a hub and extenders and stuff too. Sometimes you just gotta make do :)

The title and question are bit disconnected. You can connect more fans to PSU with splitters. Controlling old style LED fans which have same connector for fan and LED will dim when you lower speeds. But if they are 3pin. If they are PWM, LEDs will remain at full brightness. You can control both PWM and 3pin fans with most modern (2012 and newer) mobos. Whether its done with Speedfan or mobos own software/BIOS, depends on mobo. On newest mobos, Speedfan isn't always option.
