Here are some good parts for a good custom watercooling setup:
Swiftech MCP655-B 12V Industrial Water Cooling Pump *Without Speed Adjustment* 1/2" Barbs
Swiftech MCP655 12V Industrial Water Cooling Pump 1/2IN Barbs *With Speed Adjustment*
(These following rads are best used with some high CMF fans because they are thick):
HW Labs Black Ice GT Xtreme 240 Dual 120MM Water Cooling Radiator Black 1/2IN Barb
OR if your on a tight budget, this rad:
HW Labs Black Ice Xtreme II Dual 120MM Fan Water Cooling Radiator 1/2IN Barbs
(These following rads are best used with some lower CMF fans because they are thinner and have a less dense cooling fin structure):
Thermochill Pa 120.2 Dual 120MM Fan Water Cooling Radiator 1/2IN Barbs
(the thermochill is thick, but it seems to perform well with both high and low CMF fans, but of course better with high CMF fans)
Swiftech MCR220 Quiet Power Dual 120MM Water Cooling Radiator Black G1/4 Threaded
NOTE: These are the 2x120mm size radiator, they also come in 1x120mm, 2x120mm, 3x120mm and the Hw Labs make 4x120mm radiator sizes.
High CMF fans will always get you better temps with thick rads.
So if you dont mind noise go with these:
NMB-MAT (Panaflo) 120MM Hydro Wave Bearing Fan 1700RPM 68.9CFM 30DBA
If you like your PC silent, go with these:
Yate Loon D12SL-12 120MM Quiet Cooling Fan 1350RPM 47CFM 28DB
D-TEK Customs Fuzion CPU Water Block (a favorite and block of choice on the forums here.)
OR trailing close behind it:
Swiftech APOGEE GT/GTX
GPU nVIDIA 8800 series:
For you GPU, there are 2 options, a full coverage block that covers everything including the RAM, or one that just covers the GPU core and cools the other parts with passive cooling:
(personally i prefer full coverage but results show that just the core one gives you better temps)
Ek Water Blocks Full Coverage NVIDIA GeForce 8800GTX/GTS
Danger Den Full Coverage NVIDIA GeForce 8800GTX/GTS Water Block
Just GPU core coverage for the GTX:
Swiftech MCW60 GPU Water Block for Most NVIDIA & ATI Video Cards
Tygon R-3603 1/2IN ID 3/4IN OD OR 7/16IN ID 5/9IN OD
Masterkleer Pvc Tubing 1/2IN ID 3/4IN OD OR 7/16IN ID 5/9IN OD
Some like the 1/2IN and some the 7/16IN.
As tygon is more flexable, but also much more expensive than Masterkleer, i suggest you use Tygon for the tight curves you will need in you system, and the cheaper Masterkleer for the straight parts.
Save you some cost that way.
Swiftech MCB-120 "RADBOX" Revision 2 Black
You will need one of these to mount your radiator at the back of your case.
A "T" Line or reservoir: (OR both)
Now you can use what they call a "T" line or a reservoir in your watercooling loop.
Swiftech MCRES-MICRO Clear HI-FLOW Water Cooling Reservoir. There are many good reservoirs out there, you just have to pick one that suits you liking, they all share the same purpose, which is just holding some coolant.
For a "T" line you will need 2 parts:
Polypropylene 'T' 1/2IN Barb
Danger Den Delrin Fillport W/ Wrench They come in different colors.Blue,black,brass,etc.
For coolant there are many choices you can go with, look up some idea's on the forums.
Pure distilled water with 0% addatives will give you the best temperatures.
For much more detailed info you can go here:
Personally i like these:
UV Reactive Pentosin G11 Coolant Additive (Blue)
You will also need a biocide to kill some evil algae growth in your system.I use this:
Petra'sTech "PT_Nuke" Concentrated Biocide (10mL)
I really like www.petrastechshop.com
I order from them all the time, they have great stuff and some excellent customer service.
For examples on "T" lines and all that take a look at My Rig in my sig bellow.
