who has done h20 and phase change both? questions inside.

its time for me to do my "better cooling shopping" research.

this gives me 6 weeks to find and decide what route to go.

atm im awaiting some parts for rig,but specs in sig for what ill be useing mobo/cpu wise.
for now ill be useing an alpha pal 8942T with a 90mm fan.

being able to oc a precott good is gonna take h20 or phase change cooling.ive done refer h20 several times with amd.
was ok but was a pain in the arse controlling temps and condinsation.
so im wanting not to go that route.plain h20 would be fine tho.

anyhow my questions.
1.was condinsation a big pain going from h20 to phase change?
2.did the extra mhz from phase change make it worth the costs?
3.did you find you was able to service the phase change if something needed worked on?
4.if you could start over which route would you go again?
5.used h20 parts dont scare me but would used phase change cooling scare you?
6.can phase change be run 24/7 for folding?

it seems most my questions are mostly about phase change,but i want peoples help who have done both couse i want to see things from your shoes.
well thats all i can think of atm.
