The Thermaltake fans at full speed are louder than the Noctuas', but they perform similarly on the low fan speed setting. Some users may not be bothered by this; there are some that want the system as quiet as they can get it. Thermaltake was considerate and included a fan controller. The controller is great as its selectable mode for either PWM or VR is nice. It lets the user to set the speed they can live with and forget it, or let the system control it, or even switch between them. On low speed the Thermaltake 140mm fans are nice and quiet, but on high they are loud enough that you will notice them.

Thermaltake are clearly going after the enthusiast performance crown with the release of their latest Frio Extreme cooler.

The Thermaltake Frio OCK is well designed and performs exceptionally well. It definitely manages to keep up with some of the best coolers on the market today.
 

Thermaltake has once again shown why they make some of the best coolers around. The Frio Extreme performed pretty well on our test bench and was not as loud as that of the Frio Advance which we test just last week. The dual tower heat sinks has once again top the charts of being the best technology to get the best cooling performance.
