Extreme cooling questions and help needed?!

[ciscokid454]

Ok, i'm using an old slot A kryotech connected to a custom home made water block to chill my water.
I've got a swiftech mcw-5000A, mcw-50 and danger den zblock chipset cooler.
also BIX, not going to power the fan on the BIX, unless I decide to control temps that way.
Ok, testing system today.
NO LOAD on it at all, meaning, I haven't powered on the pc..
just testing the watercooling for leaks, and I wanted to see how low the water temps would get with the kryotech.
Temps got to 55F when I powered it off, as I noticed condensation forming.
My questions here, looking at various sites on the web and threads in the forumns here..
I need to use silicone to seal up the cpu socket?
use dielectric grease in the cpu socket pin holes?
Do I need to use dielectric grease on the top of the cpu as well?

also, do I need to use silicone or D.G. on the 9700pro? and if so, where and how?
I apologize for asking these questions, i've never done anything this extreme, and I don't want to fry anything.
obviously when the cooling systems under load, the temps might not get that low...but I just don't want to take any chances..
the dew point was really low today, hence the 55F when condesation started.
Also, any other thoughts or ideas on this?
thanks in advance
