(how do you spell mabey??)
Anyway.....My question,their are alot of reviews and stuff out there but I need opinions from actual use or some kind of positive knowledge on performance and quality.
What is the BEST cpu wc block for socket A 462? Realizing they have an adaptor bracket avail. for screw through mobo ones. I need 1/2" lines and MUST be able to take subfreezing temps. (I'm going to insulate it of coarse)
second thing I'm lookin for is a GOOD high flow 1/2" pump. I would rather have 120v so I don't tax the psu.
And also I'm planning on precooling and post cooling controls (before and after system is running)
As I've mentioned a few times I want to make an EXTREEM wc chiller.
I ran some heat load calculations through my local refrig. supply house's computer ($400 program)
I found out a dorm fridge compressor can cool a chiller system and get temps in the 30's F.
If I wish to chill REALY cold I need a bigger compressor. Which I have, I'm trying to design a chiller system that can be constructed from an old window A/C ( they can be found relatively cheap) and have the capacity to reach sub freezing temps.
I'd like to come up with a chiller system that ANY modder can make from a window A/C .
Then write a "how to" guide.
I want the best cpu block and pump so that I can show the top end performance.
this will be a valvable "add on" to a standard wc system. Meaning... unless you wish to depend on an old A/C to cool your system only, I'm going to have a normal wc setup with a radiator that you can "switchover"
to a chiller for oc'ing and gaming and such.
I'll try to find means of easy disconnect due to the fact that most people wont want a window A/C dumping all that heat in thier room and would probably have it outside and run wc lines in to the pc.
The point is a system that gets temps comparable to a phase change system but ALOT less expensive and you won't need to play with any refrigeration stuff.
Basically "mod" an A/C into a chiller.
That most modders can undertake and have cooling performace of phase change WITHOUT spending a grand or more! I want to stay under $200.
Any opinions on the pumps and cpu blocks?
or suggestions on the overall idea is welcomed aswell.

can't really help you with your WCing questions but its spelled "maybe" in answer to your very first question

Thanks. I was having a brain fart.
As an update: I experimented with an ice machine water pump and some 1/2" tubing.
I'm getting alot of cavitation from the pump, but I'm running F@H and online also paying music with WMP which normaly has me at 105-110F now I'm holding at 80F with the system at idle I have to startup something to keep the cpu block from sweating (35-40F) I didn't do any insulating yet

Again,Use the danger den blocks with the brass top option.

This should keep you busy for awhile.
when you finish these i've got more.
almost forgot the holy grail of Phase change Helix Technology Corporation
Enjoy.

At those temps / glycol mixtures the viscosity may become a significant factor in water block performance. Would suggest a non-accelerator plate and more free-flowing design ala Apogee, MCW6002, Maze4, etc...
