Noise

The noise of this cooler is all dependant on what your preference is. Due to the provided speed controller you can have the cooler running at whatever speed you prefer. At minimum the VF-900 is genuinly silent and would work perfectly in an silence enthusiasts case. At max the cooling is obviously quite a bit better, but the noise levels do rise enough for the fan to be heard above quiet case fans. If you want slightly more performance you can skip the fan controller and just plug the cooler straight into a 3pin socket on your motherboard; however this raises the noise level further and the performance hike is only a degree or two.

Cost

The Zalman VF-900 comes in at the £20 mark with some retailers which is about average for a GPU cooler of this type.
