vapochill/phase insulation questions

post #1 of 7
Thread Starter 
well, after reading all the post, and checking other site and everything, i still cant find an answer to a few questions.
im really considering moving my rig to phase change, but had questions about the insulation part of the mobo

some posts talk about sealing the entire mobo, some dont, which method is needed?

looking at pix and such, it looks like you just seal the chip with "foam" and mount the phase head and thats it. is there other insulation here that im not seeing? some people talk about grease in the socket, is this needed?

if i bought a vapochill or mach II, what specific insulation needs are there.


im on the edge about buying a setup, i just need these few ?s answered.
Thanks,

frank

no you dont need to seal the entire mobo, jsut the area around the cpu that is going to get really cool, i know that the mach series comes with (usually you gotta buy it) a kit that comes with seal string and stuff to make a nice seal and it also has a heater for the back of the mobo to aid in preventing condensation, the only thin extra that i do with the mach II setup is put dielectric greese on teh cpu socket area to seal up the pin area jsut in case

i am not as familier with the vapochill butits the same concept, you should be able to get a kit for sealing it up on most mobos and jsut ad the dielectric greese to the cpu area and your golden

in all my setups i also put some dielectric greese to the area directly behind the cpu on the back of the mobo jsut to protect the little resister things back there

but you must be carefull since sealstring whcih does a really good job wont work if you get stuff like dilectric greese between it and the mobo

once you do it once or twice its really easy

You do not need to insulate the whole motherboard. Only the areas that may get cold. Insulation is to prevent condesation that may occur if temps drop below ambient. This means the area around your CPU socket, front AND back. There must not be ANY air that gets cold. This includes any air in the CPU socket. Therefore, dielectric grease is needed in the socket to be safe. PC phase change units come with a heating unit. These fit on the back of the motherboard to help warm up and reduce condensation.

Here's an installation guide:

might as add on to this thread since i have questions too.. when using the heater strips on the back side of the motherboard.. can you still use the grease with it too.. like slap the patch on then grease up the patch and the areas around it.. ?? and as for the grease is it possible to lay down to much inside the socket.. i know with the s478 its pretty easy to grease it down.. but do you use the same tatics for the the 775.. do ya just squish a bunch of it into the pins put the cpu inplace and lick it down .. till like the stuff squirts out the sides.. or what ??

Well I documented how I did it in my ICE thread linked in my sig.

After a few mishaps I got it down--no heater with my Chilly1

I used regular old Vaseline instead of dielectric I prepped the area around the socket with liquid electrical tape and I packed the soceket with the white petroleum

I used foam on the backing plate.

Because the caps are so close to the socket on my mobo I layed down even more white petrolatum where the phase head will seal.

Now my unit came with no kit--no sealing stirng nothing

I used closed cell foam and made my own "hood" for the evap head and it works great.

nice.. the setup i have includes the kit.. all i really need to do is install the foam the backplate and heater stuff.. but i dont have any grease or liquid tape.. i thought about the tape stuff.. what do ya do just coat the board around the socket with it.. .. personally i dont really care about looks on the build im working now im not going for to much of a cosmetic look.. just some very very basic wire maintence and a couple of blacklights thats about it.. other then that i could care less if the board looked like it was painted or thrown up on as long as it stays dry and cold
