Hi all,

I'm after a good fluid to use in my loop; ideally an all in one solution that has biocide and anti-corrosion, I don't want to be mixing up additives etc. I just want to buy the stuff and pour it in, and dont mind if its a few pounds extra to save me the hassle.

Can anyone recommend a quality fluid? If it was UV blue, that would also be an improvement :whistle:

Welllllll.........Not recommended actually.

You run a standard pieced together loop of quality parts that the real WC folks use, you have no need for such arcane expensive fluids.

If you need bling, color, and UV color, please look at UV or colored tubing. It is quality and works great. The main WC forums really like the stuff.

For liquid all you need is water and a biocide. A bottle of very effective biocide is about $5 and will last 20-30 loop refills, and distilled water is $1 a gallon, you'll use less than 1/2 gallon in most 120x3 rad CPU/NB/GPU loops.

Once you read about clogged blocks, UV and colored water lasting 2 months before losing color, odd growths, and $30 to refill your loop you'll see the wisdom AND BETTER HEAT REMOVAL of good ol' distilled water with a biocide.

My standard noob cut n paste.....................

I'll steer you to some more technical links, please spend a few days (DAYS) reading posts, searching, learning.

Great place, not wayyy over the top with uber WC guys.

+1 for Conundrum.

Although I am partial to Petras blue stuff, been running it for almost 2 years now, with distilled water, and no gunky blocks yet.

Change your fluids every six months or so, no matter what you use. I also take all the blocks apart, and replace any tubing that needs it.

Thanks for the comments and links conumdrum, I was just looking at making a loop for my new vid card and it's been over 5 years since I WC anything. Last time it was my athlon64 3400+ to give you an idea. . . and that was a pretty trashy job honestly.

So, back to reading up on it.

P.S. Have you heard the stock fan that comes on the 4870x2? Sounds like a vacuum cleaner.

I'm thinking urine. I'm pretty sure that the acidic level of human urine would prevent any algae growth although I'm not sure about the corrosive qualities of it. A few drops of food coloring would likely get it the right color.

The high sodium content would make it highly conductive and corrosive.

Filling and priming the system would mean you shouldn't plug tubing with your fingers, either.

If you spring a leak (LOL) I bet (old) pee on warm electrical components smells like fried cats.

Kinda late, but here's my recommendation:

Distilled water and:

1. a couple of drops of PT Nuke.
2. Pentosin and PT Nuke.
3. Swiftech HyDrx
4. Primochill Liquid Utopia

It's a matter of opinion, but the premixed stuff running $20+ is not worth the money to me. Non-conductivity is over rated.

Distilled Water with a biocide (PT Nuke from Petras) is good. I personally like a little more flare.

Pentosin is nothing more than a VW antifreeze. It's cheap. Comes in UV blue (11) or red (12). Anti-corrosive properties can't hurt. need to add PT Nuke for Biocide.

HydrX is really anti-freeze with a biocide added - anti-corrosive. Come in any color - as long as it's green.

Liquid Utopia is an anti-corrosive and biocide. Comes in many UV colors.

I've used pentosin and HydrX. I haven't had any color fading issues with either, but I flush and refill every 4-5 months (probably not necessary, but I like to tinker).

The first two are a few bucks. The primochill is around $10.

Conumdrum and company are right about the performance of distilled water with biocide, and it is the cheapest, but.........

If you're set on an easy premix, I think the Feser1 is the best available. I can attest to it (at least the bottle of green that I had) not wrecking my parts; we had a little incident with a cracked acrylic top. I cleaned everything up with rubbing alchohol, let it all dry, changed the CPU block, and everything fired back up no problem.

Fluid XP has always worked OK for me, but it stains clear Tygon. My 5 month old loop of Feser1 hasn't yet.

In my opinion, Feser makes good stuff.

Agreed, Feser is becoming popular in the bling catagory. And I haven't heard anything bad about it yet.


Alcohol on acrylic? Hope not. Thats two things you don't wanna get close to each other.
It will crack if you clean it with alcohol, usually not right away, stress cracks will appear down the road.

Thats good to know. I have never heard that. The top was already wrecked before any rubbing alcohol got close. I don't think that was the source of our crack, but I will make a mental note for the future. :wahoo:

Danger Den was awesome, and replaced the top free of charge, (good guys there.)
