A Solution To No EK MOSFET back plates

My watercooling has evolved over time with thanks to many forum members here.

A while back, someone pointed out that my CPU/Storm did not have a back plate. Sure enough, it was bending the mobo like crazy. Then when I fixed that, I noticed the EK MOSFET blocks were also bending the mobo and the center chips did not even make contact.

This has been bugging me for some time and I actually made some aluminum MOSFET back plates as first seen made by AndyM and others. My craftsmanship was pretty bad and then someone mentioned using the copper heat sink back plates from the original mobo heat pipe assembly. I do not remember who, but it was a great idea.

I used a screwdriver and twisted it until each fin broke its glue/solder. This produced a perfect back plate and was actually quite stiff. I bought some longer screws and 1mm thick rubber to electrically isoleat the back plate from the mobo.

Here is the result. The contact is very even across all the MOSFET chips now and I am happy. Just wanted to pass on some pictures.

C'mon Eddy, can't you supply something like these with your blocks?

Neat effective solution.

Nice work, and copper goodness too, that's a great idea:up:

Hopefully, one never has to RMA one's Asus mobo... otherwise the expressions SOL and SOD come to mind.

Wow, very ingenious! I'm planning on using some Lian Li aluminum scraps from case hole cutting.

They bent when I used them on a P5k deluxe because of the mosfets on the back. Thats why we went and manufactured them out of the stainless steel to give more strength

Unfortunately, stainless steel cannot be anodized, only aluminum. IIRC, it can be black oxide coated, painted or run over a belt sander for that "brushed" look, that's about it I believe.

Had someone dimensions of x38 - ek waterblocks ( Asus Maximus Formula ) ? I want make backplates too :)

welshtom,

It is great to see you pick up the ball and produce a needed product for a small segment of people. I read your other thread, but wanted to try this method first.

I did not find bending that bad. I spent as lot of time checking and rechecking the pressure on all the chips, especially the middle ones for even contact. I also think additional resistance to bending may result after bolting it in to the mobo tray.

For this mobo, it seems to work good.

both copper and aluminum are fairly soft and i think it would bend to pressure?

i like the stainless steel solution best...

Love the backplates! Good job. I wish I had 2 right now...

Are you guys putting anything between the mosfets and the block?

Thoes chips are so tiny, just wondering what is best to use on them.

nice work man!!! i defo need one for my ek 680i mofset block...

hmm i guess someone has to do some transparent mobo tray, so we can admire said backplates, especially the colorful ones.

Stainless 1 to 2 mm thick should be suffecient for a backplate.

Search my topic in here for it and all the measurements are there!

You use the stock one as it does work, how ever i will be sending it to man that makes them out of better materials

Looks great! :up:

I send some adhesive neoprene out with all my ones, just to stop shorting of anything on the back really.


hmm colours eh :cool:

Maybe it's just me, but does anybody else see a problem with putting neoprene flush against the backside of the MOSFET chips we are trying to cool.

I mean, wouldn't this inhibit the natural dissipation of heat from the back of the chips? Just curious.

sanhacker,

I hope that is not a problem. My main worry was not shorting something electrically.

Talonman,

I use the EK 8800GTX FC thermal pads from Petra's. They are just the right size for the little MOSFET chips.

Thanks for the tip. ;)

why not put thermal tape between the mosfets and copper backplates? can help dissipate some heat and won't insulate like the neoprene.

:shocked:

It also won't protect against shorting out the MoBo either. ;)
