answer:That looks like a pretty good gadget, the fan is a good idea, active rather than passive cooling, especially if it happens to draw the heat from your machine’s left side where the CPU probably is. Having a USB hub can be pretty handy too. I can’t tell how that’s powered – does it get its juice from your laptop’s USB port? The laptop coolers probably all do that but note that runs additional power through the laptop to get to the USB port adding a little bit of heat. You might try some passive solutions as an experiment. We have an old MacBook propped up with a couple **** corks at the back and that makes enough space to allow convection cooling to make a big difference.
