I picked up a few sheets (and now that I see it, I got way too much) of neoprene and a tube of conformal coating and some dielectric grease from DD and it arrived today. The neoprene sheets don't have adhesive backings, so how do I attach them to the motherboard? Do I put it in the wet conformal coating? Or does it simply not get attached? And how long does the conformal coating take to cure?

The Conformal will be really dry in about 12-24 hours, just depending on the humidity.

I stick my neoprene to the mobo with di-electric grease or petroleum jelly. It will stick neoprene to neoprene pretty well to.

If I'm really building up layers of neoprene I'll stick them together with "Liquid Tape" sometimes also. Your just trying to make everything as air tight as possible so you wont have condensation.

EDIT: Be sure to try your mobo out for a few days before you proof it to make sure you have a good one, most of them wont take a proofed mobo back.

Bin it all and go buy adhesive soft neoprene.

You dont need the grease or conformal

Mine runs 24/7 25c below ambient with out them ... dielectric grease tends to wreck more motherboard due to beginners installing it than from any water

What's the danger in using Dielectric? How can it be misapplied?

Good question..

..I always proof mine and grease the socket, even then my chip will get condensation in the socket and I'll have to dump it out every few months.

If you don't turn your rig off the condensation isn't as bad since it's not warming it up. If you turn it on and off with-out grease in your socket the condensation will freeze and bend your pins. Or you can just get good old fashioned pin rot.

About the only thing I don't proof well are DICE rigs since they are only run for a short time and then go back to whatever cooling solution you normally use, it's still good to dump the condensation out of your socket.

Everything's done and seems to be working well! I greased all the pins on the socket, and after installing the retention plate and locking it, removing it shows the entire bottom of the CPU is covered. I think that means no air is getting in

. I coated the metallic points on the back of the mobo only, then took a piece of 3/8 neoprene, buttered it up with dielectric grease, and slapped it on. I coated the top of the mosfets with dielectric instead of conformal since the sink goes on top. The front I covered everything about 3 inches radius from the center of the CPU. The entire northbridge/mosfet/southbridge set is cooler since they are all linked via heatpipe, and the TEC's cooling transfers into the board. Currently HWMonitor (with an adjusted Tjmax) shows 14C and 1C, I take it that's a stuck sensor, but EasyTune6 reports that the motherboard sensor is at -11C at the time of this typing

. It seems all is well

So what you're saying is, for a 24/7 setup there pretty much isn't any good way of keeping 100% condensation out of the socket (or atleast enough that it would evaporate on its own)?

HaHa..

..Good deal! Now start jacking that v-core and Mhz..

..I kind of like proofing myself, it's kind of fun.

Heres a good example of a chiller guy with about our temp's who under-proofed;

See I have fried my DS3L mobo because of condensation. I thought I had everything good to go.
Came home and theres a puddle of water on my mobo. everything was still running. shut her down got all the water off I could let her dry for 2 days back at it. the mobo lasted for about 2 hours then it fried.

Ultrasonic2 get everything nice and cold and tell us how it goes for ya.

as ira-k was talking about grease on the pins I had to do this. I started clocking everything was running fine then it started to flake out. even at stock speeds. popped the cpu up and what do u know little bit of water there.

Pretty good read..Source...Whats the best way to put insulation on my apogee GT? - Page 2 - Overclock.net - Overclocking.net

People bend their socket pins while applying it

it's almost impossible to get all those liquids off and therefore .. the board is hard to sell second hand and to return if something does go wrong.

and you simply don't need to do it

Can you tell us about your TEC rig please ?
