I am currently in the process of building a liquid cooling system. I already have most of the parts. I am buying a gtx 480 and I am running a loop exclusively for it. I am planning on going with either a evga hydro copper gtx 480, or a standard one and buying an after market cooler from danger den.

My parts I already have are:

1 x Koolance Radiator, 4x120mm, Copper Hort. [no nozzles]
- Nozzles: Add Nozzle Pair, G1/4 Barb [13mm, 1/2"] NZL-V13KGB

1 x Swiftech MCP655™ Series 12 VDC Water Pumps
- Water Pump: With a speed controller (part # MCP655)

1 x *** NEW *** Danger Den RAD-Reservoir
- Nozzles: Add a Pair of Danger Den 1/2" Barbs

1 x Feser Tube Active UV Hose 2.5 Meter (8 feet) - Retail Packed - 1/2" ID (3/4"OD) - Clear / UV Blue


Parts I am gonna order are

12 x Koolance Resuable Hose Clamp [19mm, 3/4" OD]

3 x PrimoChill Anti-Kink Coils - UV Blue
- Anti-Kink Coil Size 3/4" will fit 3/4in O.D. Tubing

As this is my first water cooling setup, I have a few questions:


1. I was gonna use worm drive clamps, but I like the clamps above better, and I've heard the worm drive clamps cut into the tubing and cause leaks. I've heard the clamps above are better because as the hose shrinks the clamps shrink with it to help seal it better. So my question is has anyone had any problems with the clamps above?

2. What is the best coolant to use? Ive read numerous articles, and I can't decide. I want a non conductive coolant, preferably uv blue. I want something that is gonna last a long time, and I am not concerned with overclocking so much as longevity. I have narrowed it down to 3 types of coolant:
a. Fluid XP+ EXT (Extreme Performance) Coolant - UV Blue
b. Feser One F1 Cooling Fluid - UV Blue - 1 Liter
c. Innovatek Protect 1 Liter Non-Conductive Water Cooling Fluid

Fluid XP+ Ive heard turns gunky but it says it lasts 5 years and is non toxic- not many reviews
Feser One I heard stains hoses and can kill your skin if you got it on it- but it has high reviews, but again I read it turns gunky
Innovatek I haven't really read up on it, but it has good reviews

I really don't want to go with distilled water and mixing stuff, because I hate mixing chemicals, and I would much rather go with a premix all in one.
Has anybody had any long term experience with any of these products?
Does anyone have any other suggestions?

3. Another question I have is lighting and algae buildup, I've read numerous forum posts about people getting algae and build up on there blocks, some say use dark hoses, but my reservoir is crystal clear, and i'm mounting it on the outside of the case, so it kind of rules out using dark hoses. Feser has a black coolant that turns clear blue in uv light.
Some posts i've read uv light is bad, and some i've read is good. But i've also read uv light of a certain spectrum is used in water purification just for the purpose of killing microbes.

So my question is, are the uv leds used for modding good for killing microbes in my water loop? If not are there any kind of bulbs I can purchase that will work in my system for that purpose? Preferably 12v low heat UV would be best.

Solution
DO NOT use Pre-mixed "coolant". ALWAYS run Distilled water and some PT Nuke or KillCoil.

This is what can happen with pre mix: http://www.xtremesystems.org/forums/showthread.php?t=226632
You DO NOT want this to happen. Also, note that this has happened to MORE THAN one person, so it is not some isolated case.

. I want a non conductive coolant, preferably uv blue.
That dosen't exist. Over time, ALL coolant will turn conductive.

1. I'v never used those clamps, so can't comment on it.

2. See above.

3. See above. PT Nuke/KillCoil will stop alge,etc build up.

4. Is that Koolance rad full copper? There are a quite a bit of Koolance rads using Aluminium....

5. As for the UV light, you need a VERY STRONG UV light. The...
^ By the looks of it, you don't need to use KillCoils with the HydrX:
Recommended for Swiftech and all other brands of liquid cooled products. HydrX prohibits oxidation, formation of algae, and improves heat transfer. UV sensitivity makes this a great addition to any show piece computer case.

Specifications:

* Mixing Ratio: Mix 1 bottle to 1 liter (33 Oz) of distilled water.
* Anti-Freeze Agent: Ethylene Glycol

Imo, it's still best to use UV tubing. I prefer a pure system :lol:
