Is there a Quark 125B thermal problem?

You should really use the Arctic Alumina from Arctic Silver to bond the aluminum slab to the FETs. "Arctic Alumina Adhesive is a pure electrical
insulator, neither electrically conductive nor capacitive." here is a link http://www.arcticsilver.com/arctic_a...l_adhesive.htm . When I did mine I could not find it locally anywhere so I had to order it online. PC shops online are the best place to get this stuff. It is good stuff, but it's a perment bond!

I only bonded the outside FETs to the slab and case and did nothing on the aluminum slab that is sandwiched between the boards.

Your pretty brave doing this on a brand new controller! :027: but it does make a difference especially for bigger vehicles. It seems to cool quicker and overall more efficiently.
