Fan controllers

[Manners14]

I'm running a corsair 450D with 3 fans at the moment, the stock ones. But I have just purchased a pair of the corsair AF140s for the exhaust and I was looking at getting a controller to limit the exhaust fan speed to keep it quiet!

Just wondering if anyone has had any experience with this http://www.overclockers.co.uk/showproduct.php?prodid=BB-010-AK&groupid=701&catid=2331&subcat=189
As I'm looking for a manual controller that is pretty cheap. It has very contrasting reviews so I thought I'd ask on here.
Cheers!

I was just going to have the manual controls so I don't need to run them at full whack all the time

Ah right I didn't even think about that... Although it seems I only have 3 ports for fans :/ and with me wanting to add a couple more I didn't know I could split them unless I had to run them at the same speed...
