Default How can I keep my mosfets cool (4850)
I have sawed-off the end of the stock cooler and screwed it on to my mosfets and when I touch it it's boiling hot.

What can I do to keep it cool @ load?

It's normal that they are hot. But if you really want to cool them, you will have to find a way to point a fan directly to them.

Wait, I'm not exactly sure what you've done here. Do you have a pic, or could you describe it a little more? Sorry, I'm just curious.
