Hey Petra, I have a 302 (RAD) that I can hook up to my RD-30, I have been using it lately as I am minus my 120.3.
With a Storm G5 and Maze 4.
I am debating getting another 302 as they are only 20$ Run dual 302s on a RD30 using 4X 120X 38mm San Aces :-) W/ Masterclear tubing.
Also, if you remember our last IM discussin, you could have an RD-30 for testing your fluid in a more structured testing environment. :D
Why not call it "Hound53" since it IS his mix? That way it could be sold on both sides of the Pond under the same name. :toast:
Ya, that or let him pick the name, think of it, immortalized in WCing for an additive! ;)Quote:

Correct my math but this is about an 12% mixture..so we could fraction it into small volumes with same concentration correct....
My loop holds less than a liter of volume and I would like to mix in smaller amount of distilled water
I received the concentrate yesterday. I have used the current solution of 3% Zerox Super Racing coolant / 97% distilled water solution for several months with good results.
I drained the loop without removing either of the water blocks. I refilled the system with the Petra Tech solution, mixing the solution as the label suggested 1 bottle solution to 1 liter of distilled water. The fluid bled completely within two hours with my 3/4 inch t-line. The pump might be slightly quieter than the zerox solution I had before, but it is hard to tell for sure. It definitely is not any louder. I love the clear solution.
It gives me the exact same idle and max load temps as the original zerox solution, which is awesome!! I have a 23c delta between idle and load with both solutions at the same (+-1c) ambient temp. I am very impressed with the solution so far. To sum it up:
Positives
+same temps as the current best solution
+clear color, no more pink!
+possibly slightly lower pump noise
+bleeds easily
+minimal foaming
Minus
-NONE!!!!!!
I will continue to use the solution and monitor for any growth or evaporation. I will not be able to comment on whitening of tubes, as mine are already slightly milky.
The following screen shots reflect my testing with both solutions.
All the temperatures and equipment used are listed on the screenshots. If anyone has any questions please feel free to ask. Thank You Petra for allowing me to test this solution.

Yeah, that should be fine. As for an estimated expiration date, I'd think that it would be fine for quite a long while (easily over a year).Quote:

I offered to test the conductivity and resistivity (inversely related) of Petra's coolant. Petra sent me a bottle of the coolant concentrate which I mixed with the appropriate amount of distilled water to create 1L of coolant. It should be noted that the distilled water used was never opened until this test.
The testing procedure was handled as follows. I first took the graduated cylinder and cleaned it thoroughly with a bottle brush from our lab, it was rinsed with the deionized water, which I make continuously in our water plant. The properties of the deionized water make it much cleaner than the distilled water or coolant used in the test. A glass mixer from our lab was also cleaned in this fashion. The meter used, a (Myron L 6P Ultrameter), was then rinsed and calibrated with a conductivity standard solution from Omega Engineering. The coolant was then used to rinse the meter, and tested for conductivity, and then resistivity. The figures shown below show the coolant's conductivity at 23.23microsSiemen/CM, or 43.06KOhms/CM. The distilled water was also tested, as a point of reference, and measured at 2.65microSiemen/CM, or 378.6KOhms/CM. Finally, the meter was re-checked with the standard solution, to ensure that the meter did not change.

I 'll be willing to try. I even just finished my loop, it's been cleaned out well and currently running your pentosin and Deionized water with a silver rod in the resevoir. Put me on your list if you want me to try it out w/deionized water. I also have a ntc thermistor attached to the side of my naked core (industry grade, not those $5 pieces of junk).
I am about to set up a fairly high end loop for my CPU/GPU's/chipset (see sig) that most of which is on it's way from your shop. I'd love to compare this stuff to pentosin/deionized water. I'll even develope a Excel SS for the worklog/results. Let me know if you can include me.
Petra - any news on the ETA of this coolant? Problems? Success?
after a months use, no issues whatsoever. Very good product.
So you only used that biocide stuff along with destilled water, no pentosin or other additives added?
How's the tubing holding? No milky, cloudy tubes?
Well, it's a lot more than just biocide... but, that aside, Hound and I are still testing and working the quirks outta this stuff. Right now, the only issue that we're having some sort of corrosion reaction between zinc and aluminum--the copper and aluminum don't seem to be doing anything to each other, though.
Really, this shouldn't be an issue for water cooling loops, but it just bothers us that it's happening at all... because it shouldn't.
I've got cloudy tubing. Masterclear. Sitting in my room, with a window right above it, so it gets sunlight for a couple hours each day. This is with only Distilled water and PT Protect. No Pentosin.
Thx Alex.
I'm gonna place my order tonight and might buy a botlle or 2 of this stuff and see what it gives.
Been running a 5 micron filter for ~1 week. No cloudy tubing, yet.Quote:

I had to put this project on the back burner for a while due to other things that I've had to shift focus to. That said, the mix needs a few little tweaks (need to come up with an appropriate pH buffer agent to bump the pH to around 8.0) and more conclusive stability testing.Quote:

i'm about to re-do my loop and I live in the Bay Area.
Let me know if you still need anyone.

LoL. I forgot this was in my loop.
Out of curiosity, how's it holding up?Quote:
