I was finally able to get my q6600 (after testing) to where my 680i couldn't...

just use distilled water with a biocide, can't beat it in a non chilled loop

microcenter special + distilled water here...and it's still up and running...

this coolant claims to be Non Conductive, That interests me :P

this one is MUUUUCHHH better



FAR MORE interesting

Hey, i had another quick question, i've talked to a few people, Gary from Sidewinder was one of them.
they are a bit worried about a single mcp655 pump to run through my gpu/chipset/cpu and 3 rads in a mountain mods case.
i know nate said that its a beast and he has ZERO problems going far distances of tubing with his, but what do you guys think? would i be better off with getting a double pump custom top type thing? or should i just stick with a single mcp655?'
also i'm worried if theres too much pressure with 2 pumps, i'm worried ill run into leaks from the extra pressure traveling.

oh... I was thinking about that last night.  my ONE mcp 655 goes through this entire loop (not necessarily in this order:
Triple Rad
Triple Rad
Double Rad
Plexi Res
Plexi Res
Chipset cooler(my custom made one)
Mosfet cooler
Chiller Res
20+feet of 1/2" tubing...
AND THE OTHER CHILLER PUMP off!!

(the other chiller pump is normally used, but on occasion I have forgotten to turn it on, and you still see water cascading down the chiller over the evaporator when I forget to turn on the primary pump.  When the primary pump is on, the flow increases)

If that isn't a testimonial, I don't know what is.  But, if you can afford 2, then by all means.  If you have 2, you can also personally try separate loops

if you were going to go with a 2 pump system I would suggest a top like OC333 suggested and two MCP 355s

but as nate has proven the MCP-655 is a monster pump, check out this thread if you want further proof:

that monster res/rad has a 2gallon reservoir ;)

mines got slightly over 2 gallons of prestone.  I think he said his Honda radiator held around a gallon.  I don't think the quantity of liquid matters.  I have always wanted to put a car radiator outside my window during the winter for free chiller cooling.  I am helping a friend do that now.
