EKWB EK-CryoFuel Concentrate PC Coolant, 100mL, Clear

I was a little hesitant with a few of the reviews I read online, but I was able to fill my system with this without issue and it looks great. I did a standard flush (5 times w/Distilled) to remove the horrible Mayhems Black Opaque coolant I had in there previously.Sidenote: I likely should have pulled the entire thing apart because I have a few leftover marks from how badly that coolant broke down in my loop. Mayhems immediately broke down several times when I put it in my loop before. I followed all of their instructions to the T, even their own video on YouTube: Blitz Kit 2 for 12 hours, flushed repeatedly and still had issue after issue within an hour it would start breaking down.Back to this, it looks great the colors shine brightly on my RGB and my system runs almost 10c cooler and I scored the highest I’ve seen with this PC. Again, your results may not match this simply because of how badly Mayhems performed in my loop previously, so I likely could have spit in the reservoir with better results.

So far color looks great. No complaints yet. Will it "dye" my blocks? I dunno yet. I dont care though. Generally when this happens its easy to clean. And if your like me you'd probably be cleaning your blocks frequently anyway even if you didn't have colored coolant.I've never had dye issues on my hard line tubes. Soft tubes did stain....but they are soft tubes. That's gonna happen no matter what. What I can say, is even if you run clear fluid soft tubes will lose clarity over time. But again when I did use soft tubes I changed them out frequently enough o didn't care if they stained. Furthermore as long as I kept on with the same color...what do I care of if its stained the same color.

I know there are a lot of mixed opinions about this product, but the three bottles I've used over the past three years have had no issue with performance or appearance. By far my favorite coolant for my custom loop!

This is my 3rd go around with EKs mystic fog coolant. I've tried multiple opaque/solid color coolants over the years and not a single one lasts. Don't care how it's advertised or how clean and preped your system is.. They all brake down and lose their color leaving your waterblocks caked with sentiment. EK mystic fog is the only one that doesn't. To be fair, it's considered "semi-opaque" which is is. But its a solid enough white with proper lighting to look absolutely awesome! But my goodness is it pricy. So I suppose if you want it, fork up the cash!

I was on the fence with this product but decided to try it anyway. I will say that I mixed it just as the directions stated 250ml of concentrate to 750ml of distilled water. basically just dumped the contents into a container then filled the 250ml container 3 times to get it pretty close to right on. As for the RGB aspect I can say it does what it says it will. I tried every color just coming from the fans and it really made the RGB pop. I'll update if I have any issue down the road but so far so good.

It makes my loop looks juicy and tasty (trust me I didn't drink it) , very vivid color. I have some gunk from my previous build so when the pump turns on it looks more like a solid orange color but when the coolant is still it looks like apple juice. I think the color will look better if I clean my whold loop before the build.I just hope I have some more dye because I wasted a lot of colored coolant when I was filling my loop.....I will update if the color changes in the future.

I recently switched over from using just distilled water and PT Nuke to using 900ml distilled water and 1 bottle (100ml) of this clear EK-CryoFuel in my custom loop. Before using this liquid I completely disassembled and cleaned all of my components which consists of an EK Velocity Nickel/Plexi Threadripper block, an EVGA Hydrocopper 1080 Ti FTW3, an EK XRES reservoir/pump combo, a Black Ice Nemesis GTX 420 Radiator, PrimoFlex Advanced LRT tubing, and all EK-ACF compression fittings. I even cleaned my radiator with a half and half solution of white vinegar and distilled water and flushed it with distilled water until no more sediments came out (I've used the radiator for several years now, so it's to be expected).I then rebuilt everything and added in this coolant mixture. Within hours of bleeding the loop and topping off the reservoir, I noticed small blotches appearing on the inside of the reservoir; if you've ever seen the effects of "hard water" on glass, it looked a lot like that. This was a brand new, never before used reservoir tube from EK, I replaced it when I rebuilt everything. I didn't think much of it and decided to let it all rub on and off for a few days and see what would happen. My temperatures were nominal, the Threadripper was overclocking itself with plenty of thermal headroom, the GPU was chilly.So two weeks later I was looking inside the case and specifically the CPU block. One nice thing about the Plexi top for the EK waterblocks is that you can see if you're getting any kind of buildup in the fins or other parts of the block. Guess what? That's exactly what I saw! It was a pale yellowish goop that was forming around the jetplate near the inlet port. I also noticed the blotches in the reservoir had also gotten more numerous and I saw debris sitting on top of the water in the reservoir and blowing around near the pump intake on the bottom.That was enough for me. I drained everything out, flushed it with distilled water several times and disassembled everything to clean the CPU block out and reservoir. I didn't notice the buildup anywhere else. I rebuilt everything and went back to using my PT Nuke and distilled mixture and haven't had any of the issues since.I have always really liked using EK products in the past, I still do, in fact! I've never used their coolants or coolant additives though, and after this experience I think it will probably stay that way. I'm saddened to have to write this negative review, but my hope is it will help EK improve their coolant additives in the future and in the meantime save another person from having the same headaches I had when using EK-CryoFuel Concentrate Coolant, 100mL, Clear.
