Some people have been able to open their notebooks and flush out the heatsink to make it cooler again.
Even using a non-powered device to lift the bottom of the notebook for more airflow to the vents (like the Targus Podium Coolpad) helps. See www.Targus.com
The 2nd solution works similar to the Targus but it is using power to generate even more airflow. Note that Targus has a coolpad with fans also that runs off of USB.
I don't know the pricing of what you are looking at but the Targus solutions (and Target and Office Depot, etc sale many of them retail) are in the 19.99-29.99 range.
My Gateway laptop gets ridiculously hot, so I am going to invest in a laptop cooler. I came across two different types of coolers.
The Vantec LapCool 2
and the Bytecc Heat-pipe Cooler
Now noise if a big factor, which is why I thought the Bytecc one was great...requires no electricity and is noiseless. My only concern is if it works or not...I've read a couple reviews on the Vantec one, which all seem to be good, but can't find anything on the Bytecc one. Has anyone had experience with a heat-pipe cooler, and does it actually work?
