|I am not sure about your question. A laptop cooling pad is a simple device to raise the laptop off a surface and has a fan to help bring in additional cool air to improve the cooling of your laptop. If it is made well, they should last a few years under normal use. Use it whenever you will be using the laptop for extended periods of time at a fixed location (shortens battery life if not plugged in).|
Look into other methods of keeping your laptop cool:
Blow out dust from vents with compressed air can.
Turn off programs running in the background.
Never use laptop on a soft surface.
You have to be a little bit crazy to keep you from going insane.
