thermal interfaces pads on the mosfets

[MadHacker]

I made a home made water block for my mosfets but was wondering if i need to use thermal pads or can I just use Thermal compound?
I have Arctic cooling MX-2 thermal compound. it is supposed to be Non-Electrical Conductive. Link

Has any one done this before?

Anybody?

i think thermal pad will be the best. as thermal paste for best for "bonding" metals together.

Either way, post some pics when your done.

also did some searching and came up with this thread

recommending thermal pads because the board may warp causing it it loose connection.

First I'll try MX-2 since i have it available...
if i get a good connection... I'll leave it as is..
otherwise I'll go order a thermal pad..

I have been using Abit Motherboards almost exclusively for the past two years and am also heavily involved in TEC and watercooling. Because of this I usually ran into problems when I wanted to watercool the mosfets around the cpu as there weren't any waterblocks in the market that would be usable on all of them. Eventually, I started making my own waterblocks and I just recycled the thermal pads that Abit used on the air cooling heatsinks and they worked fine. However, I don't see a problem on using the thermal compounds either. Just be mindful that some thermal compounds have elctrically conductive properties (i.e. Arctic Silver).

yes I have tried something similar and my advice is don't, the coils turned black and in one year the motherboard needed to be replaced.
this is one of the reasons i made this system wiff the fans air is the way to go wiff the coils.

I think I was one of the first peps that mentioned about the coils getten really hot when ocing. A old forum poster wuzzy explained this as electrical migration. Very smart dude
