Ok, Ijust got my Vantec Lapcool2 from www.svc.com
and here are the results:
At cpu load of 100% before my cpu temp was 70C now with the Vantec at max fan speed it dropped to 65C. HD temps used to be 40-43C now HD reads 30C. At full fan speed the noise is just slightly audible - definitely NOT a problem - and isn't much louder than the fan in the Asus at 100% cpu load. At lower fan settings, used with more normal cpu loads, the Vantec will be completely silent.
This cooler is very light, part of the face part IS made of aluminum to facilitate heat flow from lappy to cooler and the fans are just great - barely audible at full speed and completely silent at lower fan speeds.
The size is just right for my 15.4 Asus but I am not if sure a 17 inch lappy would feel solid over the lapcool2.My guess is there isn't gonna be a problem but can't say this for sure.
I would deninitely recommend it to everyone especially those who will game or crunch numbers on their laptops.
