Conformal coating on a A8N32 SLi mobo
 
Hi 2 all! Superb and very helpful forums and after a long reading only period, I decided to join.

This is my 1st post so be people show mercy...

I own an ASUS A8N32 SLi Deluxe mobo and I'm about to jump from watercooling to a Qmax 437W peltier. After a lot of studying I figured out what measures I must take against condensation, and the final decision is as follows...

1) The back of the mobo is to be totally covered by conformal coating (I've already remove the cpu backplate).

2) The cpu socket, pci slots, memory slots etc will be filled with diellectric grease so as no air remains.

3) Silicone will be placed around the cpu socket so that air cannot flow under.

Now the questions:

1) How can I secure a neoprene sheet on the whole of the back of the mobo in a non-permanent manner?

2) I know that the area around the cpu socket must be covered but what about the 8 power distributors?

3) What parts of the mobo should NOT be covered with conformal coating?

Thanks in advance and remember is my 1st pelt attempt... :rolleyes:

Cover the back of pcb with neoprene, armacell, or closed cell foam on top half of mobo or 2 inchs around the cpu to be sure. Attach it with some adhesive. You can also look for rolls of armacell or closed cell 1/8" with adhesive backing at homedepot or ACE hardware.

Same with top of PCB, needs 1 inch around socket to be condensation proof. I prefer a corona X or red insulation tape paint or at least clearcoat nailpolish over the conformal coating on top of pcb. Just easier to remove and apply. The mosfets and caps will be harder to cover but all you need is to insure water doesn't drip on it.

My friend ricecrispi thank you for your reply.

Using an adhesive to secure the neoprene is a rather permanent solution which I'm trying to avoid. What if I do not use spacers for the mobo and secure the neoprene between the mobo and the case?

As for the front of the mobo I wanted to know if any components should NOT be covered with conformal coating or nail varnish for any specific reason. My mobo has 8 power distributors around the cpu for each I'm not sure what I should do.

To be more specific I'm referring to parts R47.
