this is a perfect water loop... just buy these parts.
OD = Outside Diameter
ID = Inside Diameter
1)-9 metal hose clamps from hardware store (these work the best, under a buck each)
2)-Swiftech Opogee GTZ Waterblock OR D-TEK Customs Fuzion V2 - 5/9”OD barbs (the difference between the top end cpu blocks is about 1 degree.. I choose the one I thought looked best)
3)-Swiftech MCP655 12v Industrial pump (this is an awesome pump, a bitch to get the tubing over it, but it will go…patients)
4)-1*Smartcoils 625blue (wrap around tubes to keep from kinking)
5)-10 foot Masterclear pvc tubing 7/16”ID , 5/9”OD (flexible and inexpensive)
6)-3* Scythe S-Flex SFF21F fans (for the Radiator) (fans…whichever you like the most are fine)
7)-2*Swiftech ½” OD Chrome plated barbs (for radiator)
8)-Copper T connection (for the T line) (Hardware store, get a 5/9 or 1” OD copper or brass)
9)-Feser One Fluid UV Purple NON-CONDUCTIVE Water Replacement (used about 20 OZ. for this system, 1 bottle is crazy overkill….this is not in my Picture, I changed the water, looks 100% better….
10)-Danger Den Fillport (goes top of T line to get water into the system from outside, makes system look far more professional/clean)
11)-Swiftech MCB-120 Radbox (used to attach the radiator to the back of machine, or wherever you would like…makes install a breeze.)
12)- Thermochill Pa 120.3 Triple 120MM Fan Water Cooling Radiator
This is what it looks like:
***If you want to cool the GPU(s) I would build a second loop to do it proper, however this loop can easily handle a single GPU added.
