I use a static cooler without fans, it just raises the LT up to provide good air flow. It's not the best at being comfortable as it's like a square aluminum block but it doesn't require a usb port for the fans or need to be plugged in. My LT is older and only has three usb's so with a mouse dongle and a external hd that takes the other two my other option would be this Logitech unit. At the moment all my cash is going towards my desktop and the lappy isn't a focus.
