Tt Commander F5 Multi Fan Controller
 

Overclockers Club has the Tt Commander F5 multi fan controller on the test bench today and, overall, they didn't seem that impressed with the unit. Here's a quote from the full review: Even keeping the low cost in mind I just felt like the Commander F5 missed the mark, if only just slightly. It will provide you with the ability to throttle back your obnoxious fans (assuming they aren't over eight watts) for a measly $20. If you blew your budget buying fast fans and you cannot stand the noise, the Thermaltake Commander F5 might deserve a home at the front of your case. Just don't point it at your bed since the lights will blind you even in your sleep!
