Solid aluminum construction = way better heat dissipation than traditional plastic coolers.
This was made around 2004 and not many were sold due to the expensive cost!
This uses twin Y.S. Tech .15A 5v fans that move some serious air.
Sadly, one of the fans is noisy and needs replacement.
Or, you could add some holes to the fan mounting plate & just use standard fans... maybe some LED ones :)
Or just don't use the fans! Still cools the laptop quite a bit just being made out of aluminum.
Neat old piece of computing history that you won't find anywhere else!
