Hi all, So I built this custom loop back in November. Cleaned rad, CPU block, then ran distilled water through it for over a day for both leak testing and to rinse out any remaining particles, etc. I purchased EKWB's new Cryofuel which includes: "EK-CryoFuel also contains synergistic corrosion inhibitors to protect metals commonly found in computer liquid cooling systems. It has been tested in accordance with BS5117 (ASTM D1384) and found to meet corrosion standards for copper, brass, aluminum and stainless steel. This coolant also contains scale and biological inhibitors to help prevent fouling – thus promoting long operational life and high thermal efficiency. All EK-CryoFuel mixtures are biodegradable (90% in a period of 10 days) and will not remain in the environment or cause any bioaccumulation. EK-CryoFuel offers a 2-year shelf life from date of bottling. Designed specifically for computer liquid cooling systems, we found our inspiration for CryoFuel in cryogenic fuels that are used at extremely low temperatures to operate in space machinery. Characteristics:- Low electrical conductivity - Biological growth inhibition- Corrosion protection according to BS5117 (ASTM D1384) standards" Per their website, this is all you're supposed to have to add to your loop as it contains everything necessary without the need for extra biocide, kill coils, etc. Well, I started to notice what looked like bluish particles in my CPU block and it's been getting worse. I just built this 3 months ago and would really hate to have to disassemble it AGAIN. What are your recommendations going forward? Buy some UV lights to try and kill it, buy a kill coil? (note: I do have the EK-XRES 140 Revo D5 PWM pump so not sure whether it would try to suck up the kill coil and/or damage the pump if I placed it in the res portion). EK-XRES 140 Revo D5 PWM (Pic 1) http://tinypic.com/r/2u4j0py/9 (link if you can't see the pic below) (Pic 2) http://tinypic.com/r/301dilx/9 Besides this, the coolant has been great so far. Color and clearness has been maintained, no visual "gunking up", etc. Parts (I included amounts too but obviously for some things there are extra): EK-CoolStream XE 360 (Triple) EK-XRES 140 Revo D5 PWM (incl. sleeved pump) EK-Supremacy EVO - Gold EK-CryoFuel Navy Blue Concentrate 100 mL EK-CryoFuel Navy Blue Premix 900 mL (used this one) EK-Cable Y-Splitter 3-Fan PWM (10cm) EK-AF Y-Splitter Rotary 2F-1M G1/4 - Nickel EK-AF Y-Splitter Rotary 2F-1M G1/4 - Nickel (2) EK-DuraClear 11,1/15,9mm 3M RETAIL (12) EK-ACF Fitting 12/16mm - Blue EK-AF Extender Rotary M-M G1/4 - Black Nickel EK-AF Ball Valve (10mm) G1/4 - Black Nickel (3) EK-AF Extender 6mm M-M G1/4 - Black Nickel (4) EK-AF Angled 45° G1/4 Nickel (3) EK-AF Angled 90° G1/4 Nickel EK-CSQ Plug G1/4 - Black Nickel

DO NOT use a kill coil. Silver and Nickel are not friends and you will undoubtedly ruin everything in your loop, and after that, ekwb will not warranty your system: https://www.ekwb.com/blog...bial-algae-protection/I suggest contacting EKWB and find out what they suggest. Also, what parts do you have?

did you happen to run any dyes or additives in this loop prior to rebuilding it? it looks like left over dye maybe. either way the only way to get rid of it will be to tear it down and clean your whole loop again. otherwise it will only get worse. the rad is the most likely culprit for leftover crud. the best way ive found to be certain that a rad is completely clean is to empty it into a clear glass or plastic bowl after flushing it with vinegar and water. if you cant get the rad clean with vinegar ive used CLR to good effect. ive used a baby bottle brush in the past to clean fittings and small pieces of tubing but its usually easier to just replace the tubing. ive heard that primochill makes a post cleanup mix that is supposed to help get rid of the last little nasties too. the only additive i use is petras pt nuke mixed with distilled. it has worked great for me for years. that may be worth a try. good luck :(

+1 talk to EK - could be a bad batch Could the "blue color be from bare copper in your loop ? ---> you mention these: EK-CryoFuel Navy Blue Concentrate 100 mL & EK-CryoFuel Navy Blue Premix 900 mL (used this one) You must be careful not to introduce any contamination when filling the loop; wash hands, clean any area your working in especially around the fill point. This might be a good idea - after you talk with EK ---> SysPrep PrimoChill makes a SysPrep for cleaning as a final step, run then flush and fill with your coolant. I also use the PrimoChill Liquid Utopia™ with distilled water

I used hot water in the rad numerous times, shaking it etc., had to clean CPU block after I took it apart, maybe it was my fault because I didn't use vinegar? But I then ran distilled water through all parts for over a day in a test loop THEN assembled my loop and used the coolant above. (the premix and concentrate are the same thing. I ordered one of each so I could make more if needed using the concentrate.) There's been no temp changes either so at least that's good. Do you think using that light would help at least for a bit and clear the CPU block? Not sure if there's any buildup in my rad but there'd be no way to check really until I took everything apart.

Using Hot Water may have caused it. I use only Distilled Water Heated up on the Stove. I also rinse all the Block Parts and Even the Tubing before I install any parts. "Not sure if there's any buildup in my rad but there'd be no way to check really until I took everything apart." I would not think so because Algae Needs Light to Grow.

Well, it was still distilled water, just heated up in a Pyrex measuring cup (which was rinsed with distilled water prior) and then heated in a microwave. And true, well this room is mostly dark as we have blackout curtains. So the only time it's really "light" in here is when the PC is on and I have the lamp next to me on. Maybe it's just something in the fluid then? As you can see though, the specs are where the coolant isn't even really "touching".

This is what I use to Filter the Coolant. I filter it twice changing the Coffee Filters, I double the Filters that is. Say This Three Times Real Fast Still Distilled Still Distilled Still Distilled Faster to say Steel to Steel

I just read that some people are saying that it may be from the o-ring. The mention was that the light oil that is used to keep the o-ring from getting brittle may cause something like this. It shouldn’t hurt anything but it could just need to be cleaned out.
Again, I would just ask ekwb directly and see what they think.

Ahh, could be. It just looks aesthetically displeasing lol. I'm awaiting a response from EK.

EK responded and said that it appears to be oil from the O-ring and offered a replacement O-ring. Are there any long-term effects to NOT disassembling my entire loop to change it besides aesthetic?

It is highly unlikely it would cause any issues, but there is a small chance of course. The oil is there for a reason and I would assume it won’t hurt anything.

it wont really hurt anything but just look like crap floating around in the loop, you could flush it out since the excess oil will be gone.

I have seen this before, but I think this is simply O-Ring grease, Bitspower and EK are know for this and you will literally see green and yellow slime on the O-Ring this is harmless. You want nice greased O-Rings so they stay in place, its common practice. This is from my system and as you can see its got green slime on the O-Ring, its completely harmless, I have contacted both Bitspower and EK before on this because I was pretty concerned and thought I had algae, and they said they same thing, its harmless, sure it doesn't look that great. Also I just flush my parts when I get them with distilled water and dry them, no need for special chemicals, who knows if you will able to get it all out and how it would react to the coolant? Hope this helps and that you can get this figured out.

No, the grease is harmless, your replacement O-Ring will do the same thing after some time, never hurts to have spare O-Rings, always a plus if you ask me. I have seen people freak out before and I was in the exact situation as you and thought it was algae, but I would not worry.

I read that the 705 liquid doesn't use Ethylene Glycol but instead Polypropylene Glycol which has "worse" heat transfer properties, though that's just on paper, in practice its probably different. If you are going to use Koolance coolant just get the 702 with Ethylene Glycol, though Polypropylene Glycol is not toxic and Ethylene Gylcol is toxic. And to OP an alternative to Koolance 702 is DP Ultra Clear, which is cheaper for 5L $27.99, 1L $8 vs $89.99, I highly recommend it, but its down to you in the end. Saying 705 is the best in the end is misleading. You can clearly see on the PPC website description below.

Yeah though it does look like particles. Could be the dye/color of the coolant mixing with the grease. Quite honestly I'm not even going to bother replacing it or cleaning it until I have to do maintenance. For minor aesthetics, it's not worth tearing down the entire thing.

i hear ya, i hate doing regular maintenance much less an immediate reconstruction!. i think your right on, the dye is just sticking to the greasies.

Again great info, clear coolant if you ask me is the best, just my opinion.
i would stay away from dp ultra, the red anyways, it lost color in two different systems on me and ended up looking like light tea, not sure why. replaced with ek cryrofuel red and color has been perfect since.

Problem is because manufacturers say Use our Coolant or you will avoid warranty. I will put 100ml of Concentrate in 700ml of re-destiled water not in 800-900ml. I think that will help at least little. I think EKWB say their Clear Premix Concentrate or prepared coolant are enough to avoid alge and similar things. I mean everyone say that. I will use only Clear 100ml Concentrate but little less re-destiled water. But nothing help if you leave 10 months without cleaning. But if you change on 2-3 months whole coolant-water and once in 6 months you open block clean with hot water I think everything is fine.

It's crucial to remove coolant on 3 months and clean loop on 6-7. Cleaning I mean uninstall waterblock completely and with softest teeth brush and hot water you clean them and carefull screw to avoid damage screews, that mean perfect allen key and not tight as animal. Small force and undameged o-ring is enought to avoid leaking. I'm not sure about chemicals for nickel plated cooper fittings and blocks. EKWB say only water, that mean only water and softest teeth brush. Some people use same coolant 2-3 years, they back him inside after cleaning, that's not smart. It would be nice to someone launch completely harmless coolant for electronic component and biorganisms. If some brand get confirmation for that they could profit a lot of money on some coolant with nice smell as Arctic Cleaner for thermal paste.

bcavnaugh Did you Flush all the New Parts before using them? Petra's Tech PT Nuke Cu Concentrated Biocide (10mL) Petra's Tech Nuke PHN Concentrated Biocide (10mL) But no longer use I use this now: $14.99 Koolance 702 Liquid Coolant, High-Performance, UV Blue, 700ml (24 fl oz) Part No. LIQ-702BU-B $14.99 Koolance 702 Liquid Coolant, High-Performance, Colorless, 700ml (24 fl oz) Part No. LIQ-702CL-B
The Best but only comes in Clear. $19.99 Koolance 705 Liquid Coolant, Electrically Insulative, Colorless, 700ml (24 fl oz) Part No. LIQ-705CL-B A Good Killer, I this once a month for about 30 Minutes on all my New Rigs and once Every 3 or 4 Months for about 15 Minutes. AquaTop In-Line UV Sterilizer 10W - IL10UV (DO NOT LOOK AT THIS LIGHT WITH YOUR EYES)
Great advice though I read that the 705 liquid doesn't use Ethylene Glycol but instead Polypropylene Glycol which has "worse" heat transfer properties, though that's just on paper, in practice its probably different. If you are going to use Koolance coolant just get the 702 with Ethylene Glycol, though Polypropylene Glycol is not toxic and Ethylene Gylcol is very toxic. And to OP an alternative to Koolance 702 is DP Ultra Clear, which is around 56% cheaper for 5L $49.99 vs $89.99, I highly recommend it, but its down to you in the end. Saying 705 is the best in the end is well... misleading, but that's just my opinion. You can clearly see on the PPC website description below. Again great info, clear coolant if you ask me is the best, just my opinion.
i would stay away from dp ultra, the red anyways, it lost color in two different systems on me and ended up looking like light tea, not sure why. replaced with ek cryrofuel red and color has been perfect since.
I use DP Ultra Clear myself, never had issues, always crystal clear, heck changed my coolant the other day and it was as clear as when I poured it in, that was after a year too.

Vlada011 Problem is because manufacturers say Use our Coolant or you will avoid warranty. I will put 100ml of Concentrate in 700ml of re-destiled water not in 800-900ml. I think that will help at least little. I think EKWB say their Clear Premix Concentrate or prepared coolant are enough to avoid alge and similar things. I mean everyone say that. I will use only Clear 100ml Concentrate but little less re-destiled water. But nothing help if you leave 10 months without cleaning. But if you change on 2-3 months whole coolant-water and once in 6 months you open block clean with hot water I think everything is fine.
No not the case, really only Koolance is the one that will void your warranty if you don't buy their coolant in conjunction to their parts. I use EK, Bitspower, Barrow, TT parts, etc, not one of them had a problem with me using DP Ultra. DP Ultra you will never have an Algae problem because it has Ethylene Glycol and Algae cannot live in that at all, I believe the same is for Koolance 702. Again drained my loop after one year, the only "dirty thing was the oil from the O-Rings. That 6 month mark is for if your using those goofy coolants that will gunk up your system lol, seriously not sure why people use those coolants and then complain how there system got stained and full of gunk. The some of the best coolants on the market are DP Ultra and Koolance hands down, though the Koolance stuff is overpriced by a long shot, granted they where designed for long term use and come with every thing you need mixed in.
