MOSFET Heatsink installation

[SamzAthlon]

Im installing heatsinks on my mosfets. However, my heatsinks are coolermaster ones designed for graphic card memory...you know the square ones.

there are 12 mosfets on my board which are so close to each other that when I install a heatsink on one of them it will overlap on the other one. I was hoping if someone knows whether this overlapping can cause a problem?

You can see the mosfets in this example below.

Should be fine. Heck, with that layout you can just slap a single heatsink across the bunch... if you found one that fits.

In some electronic equipment, the case is used as a HS for mosfet's - even several of them.

Can indeed put one long (or several) across the mosfet's, just make sure their pins dont make contact to the HS - for obvious reasons.

I just laid all of them, and yeh I was sure not to let the pins touch the sink otherwise I dont think I would be writting this message atm...

Check it out, what you all think?

Looks like it comes like that out of the box. Nice.

Crispy boy... looks nice.

Obsessed with cooling, aren't we?

Those little mosfets can get incredibly hot.

The mosfet heatsinks are made from a Pentium-class heatsink that I sliced up with a bandsaw. The big heatsink was bought surplus, and was originally for a router. Its corners were sliced off so that it would fit, and it was oriented at a 45 degree angle so it could be mounted with machine screws and nuts through the board. The southbridge heatsink is part of a 486 heatsink.
All small are attached with Arctic Silver III and some epoxy around the outside.
