Zalman Optimized Vent Hole Ultra Quiet Notebook Cooler
Zalman may not be a name that you recognize quite as readily as Targus, Cooler Master, Logitech or Belkin, but they are, very definitely, a force to be reckoned with in the world of computer cooling. You’ll find plenty of very positive independent reviews if you search around the web.
They make some very effective notebook cooling pads, and the Optimized Vent Hole Ultra Quiet cooler (the ZM-NC3 for short) is a great example. In fact, low noise coolers are something of a Zalman speciality – and many users choose this brand specifically for its low noise emissions.
This particular unit has a large, 200 mm fan which spins at 550 rpm and is, to all intents and purposes, virtually silent in operation. It has a guaranteed noise level of 20 dB(A), which is about the level of noise that you might expect to experience in a library – when it’s closed.
It’s way below the normal background level in any office, or even in your living room. You won’t hear this cooling fan in operation.
Here’s a good demo video. You will hear the operation of the switch which turns the fan on and off, and you’ll know that the fan is on when the tissue paper starts to float – but you won’t hear any additional noise from the fan.
I’m sure you’ll agree, it’s very quiet.
Dimensions are 14.2 x 16.8 x 3 inches, and it weighs 2 pounds. This cooler pad could be used for laptops with up to 17″ displays.
It’s powered from a spare usb port on your laptop.
If you’re looking for high performance laptop cooling, combined with extremely low noise, then the Zalman range of notebook coolers is well worth a look. Here are just a few examples of what’s available:
