insulating area just around the core

Cablepro · 02-25-2001, 02:52 AM

seeing as the cold plate comes in contact with the core only, there seems that there would be a volume of air between the cold plate and the ceramic part of the processor...any ideas on how to insulate this?
with the assembly mounted to the motherboard, it would be difficult to get any silicone in there...
could I use an overflow of thermal grease(silicone based) to fill the gap?

It doesnt matter...there are no electronic components in there...you insulate to keep water from shorting out connections...thats all.

Joe · 02-25-2001, 10:44 AM

Ummmm No.. you want to keep air and water away from that area. Some people will use thin neoprene strips, but I like the way I did it on the Mini, and just create a fully sealed cavity there, so theres no way any humidity or anything can get in there and freeze.

One thing Alives doesnt get is, ANY air exposure to the cold parts is a VERY bad thing. Yes when you seal the area around hte core a lil air will be trapped but thats much better then many other solutions.

Electronic parts or not, you never want air to come in contact with you cold parts. And a good insulation job will get you lower temps.

Yeah. Joe went with the Plumber's goop. I used similar stuff when I peltiered my Duron a while ago. This time I'm gonna use a THIN piece of neoprene. This makes the setup less permanent.

Joe · 02-25-2001, 12:51 PM

I am really afraid of using anythnig that may have a spring effect on the cold plate. I mean how do you know that it doesnt raise the cold plate just a hair off the core, thats death for a Tbird instantly.

I prefered to use something to insure that the block would be clamped on the core hard.

so when I apply my thermal grease, and then clamp down the assembly to the processor, the excess grease should run out a bit around the core, creating a "doughnut" of grease around the core...

then that will eliminate condensation from the trapped air from penetrating the core...only the leads and cache are subject to any condensation if this is the case...and a few sprayed on layers of conformal silicone might help protect them...

does this sound about right? or am I missing something again?...I appreciate all of your advice...

Kevin · 02-25-2001, 04:07 PM

No... Joe was talking about Plumber's goop. He actually sealed the cold plate onto the CPU to make sure the core wouldn't short.

Cablepro · 02-25-2001, 06:14 PM

i'm a bit confused...what I read in the article is that Joe sealed the cold plate to the cpu around the edges, and left a cavity of air between the surface of the cold plate and the surface of the ceramic part of the processor...

please let me know if i'm wrong here...

Alives · 02-26-2001, 02:39 AM

yeah youre right and thats why i said it wouldnt matter. even if you get a block of ice or a puddle of water in there its not gonna do anything.

Joe · 02-26-2001, 07:16 AM

There are 2 facts to know when you see that:

1. The small small amount of air in there cant produce as much as a frost or even get the plate damp.

2. When I did it, it was done in a real low humidity enviroment.

But as I said, with that small of an air space theres no worry of ice, or water. That really happens when you give a cold surface access to a much more open air space.

And also... because it is air tight no air can condense... right?

Chill · 04-11-2001, 06:39 PM

Ok...I have asked this question several times now and I need to know some things. I have Plumbers Goop and want to know if I can use it the same way as the silicon around the edges and inside the socket. Also the multicolored foam you find in craft shops, can it be used the same way as neoprhine. The lady at the craft shop said it would get moldy after awhile. If so can you treat the foamies with something to prevent molding.One more question.....the conformal silcon sray.....what brand name/description and where can I find some......sorry for all the stupid questions but I need to be sure.

Doug,
Read the Chemicals article, it has links to all the sealing goodies you could ever want -- plus the links are to the cheapest prices I've seen on the web!
