External usb metal cooler

Hi would a usb metal cooler work on my blade ,there is on on e*ay for a dreambox for £2.70 inc p+p ,was thinking of the summer months when it gets a bit hot ,am already on my 2nd box after the first died on me ,anybody using one of these on blade? thanks

it would work but i find if you can put your box in the open (not in a cabinet) they tend to keep cool enough not heard of a blade overheating putting a cooler on may give you problems may become to cold but again untested but for that price you can not go wrong
