Nowadays laptop coolers are big bucks but after trying alot of coolers, not one reduces temperature more than about 1-2 degrees.
I went to work designing my own custom laptop cooler taking the idea from a high end cooler and trying a 12" fan in an aluminium case, this gave me a little over 2 degrees difference....back to the drawing board.
I then though smaller fans at higher revs may do the job better, I took 3x80mm case fans running at 2600rpm and hotwired a 12volt charger to power them. This gave me another 2 degree diference.....again back to the drawing board.
I then thought even smaller fans may direct airflow better so tried 6x40mm fans at 1600rpm this again failed miserably.
my next idea involved creating a vacuum to force the air through a box like design with a silicone seal all the way round forcing air into the case.....this again failed but had better results with a 3 degree difference.
I'm wondering has any one got a drop in temp under load (without undervolting) of more than 5 degrees and if so how?
