Custom Heatsinks. Short circuit?

post #1 of 7
Thread Starter 
Hi.

I have decided to put on some custom made heatsinks on my MOSFETs on my motherboard because my motherboard lacks MOSFETcooling.


Here's my question:

Can you get a short circuit for having a heatsink over several MOSFETs? Pardon me if it is a stupid question but I'm no good at electronics :3



This is how it looks originall:


Im thinking about putting some custom made heatsinks (taking a big old one and cutting in in pieces).

The heatsinks I'm going to put shall be 5 square Heatsinks and every Heatsink shall cover 4 MOSFET (the tiny black chips in the previous picture).


And this is how I want it to look afterwards:



Can it be some kind of short circuit because I'm putting one heatsink on 4 MOSFETs? The Heatsink is obviosly made out of some metal.

Or will the cooling paste and glue make it impossible to short circuit?

Or short circuit maybe won't happen because the Heatsink is on the top of the MOSFET, not on it's metal parts?



hope I made myself clear ;p

best regards

No, you won't get short circuit - cause most of the sinks come with thermal pad which don't conduct electricity.

Nope you won't get any kind of short ^_^
The thermal pad on the bottom protects the device from the aluminum.

As others have said, no it won't short circuit. Just make sure the thermal pads you use are larger than or the same size as the actual MOSFET

Thank you guys, but as I mentioned I'm customizing a heatsink which means I don't have a thermal pad on it.

Will this have the same effect as a thermal pad? I guess so but would like it to be confirmed for safety ^_^:

It won't, I have Ram sinks on my GPU's VRMs, there are 2 VRMs under each ramsink.
No shorts yet.
