Can you layer thermal pads?

post #1 of 4
Thread Starter 
Hi


On the EK MOSFET blocks for the ASUS P6X58D motherboards I need to apply some thermal pads on the backside of the MB. The backplates that hold the pads comes without pads. This means I need to reuse the existing thermal pads from the motherboard.

On the P6X58D-E motherboard there is only one backplate and hence only one existing pad that I can reuse. However, it is possible to add a backplate to the second set of fets. I have measured the pad to be 2.5mm. I have some spare pads 1.5mm and 1 mm pads.

Can I layer/stack these to create the correct thickness?

Yes you can but the performance will be decreased as there will be air trapped between the thermal pads no matter what you do. Plus you are adding another surface for the heat to be transferred (thermal pad to thermal pad). We are not talking about something very critical like GPU or CPU itself so this won't matter much for you just understand that there will be less heat conducted.

You can, i would put some TIM in between them however.

Thanks for the responses. These mosfets did not have any cooling previously but I though it to be cool to add the backplates (prevents potential warping of the motherboard) so layered tape + backplate is better than no cooling at all I guess. Do not think I will bother with TIM but thanks for the suggestion.

+ rep + Have a nice weekend.
