Am going to buy this fan,but i noticed it came with a molex adapter and that would be good considering i only have 3 fan slots on my mobo.My question is if the fan is hooked up to the PSU directly can i still control the fan speed in the bios?,i'm under the impression that if a fan isn't directly conntected to the mobo you can't control it's speed.

Unfortunately, you can't control a molex connection in the bios. I do know that there are 3-pin splitters allowing you to connect two fans to one mobo slot (2 max).
Here's an out-of-stock one I found http://www.newegg.com/Product/Product.aspx?Item=N82E168...

No problems as long as you don't go beyond two on a connector. There are several cpu heatsinks with dual fans off of one header.
I've used them before with one fan as intake and one as exhaust for balanced airflow.

High. Try them that way first and see how you like it. You can always change it later.

Yes i guess i could...When i enter the bios it lists 3 fan's and i only have 2 that are in the mobo,i'm guessing the 3rd is the PSU fan,maybe i could see how fast they are going in there but i'm sure it will work out.
Thankyou you've been a big help

The third is your CPU fan.

well i have 2 fans and a pump is plugged in to the CPU port becuase i have a H50 liquid cooling...so i think i only have 2 unless the pump has some kind of RPM i dunno about.
