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 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.

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 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!

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.

The only reason im here now is to warn future users to CHECK YOUR BOTTLES EXPIRY DATE MINE WAS SO BAD IT HAD GROWTHS FORMING!Like another user on here i saw leave a review the top of my EK Cryofuel Clear concentrate also implies that i got it after it had expired or just as it was.I can imagine a company selling this stuff 2nd hand could probably make a good amount of money selling a product on here that they can no longer move elsewhere so long as the users dont notice or care that the product is already out of date or soon to be.So for the dates heres the details:I purchased my concentrate in june 2022 and the date on the top said january 2021. It is now april 2024 and i only opened this container of coolant to mix my total amount of coolant something like 6 months ago max. I put it in my system and then put what was left over into a PET plastic bottle perfectly sealed and left in a cool cabinet away from any sunlight.However, considering this stuff is supposed to function as a biocide and corrosion inhibitor im beyond shocked to find opaque blobs of growth in whats left over.Normally EK Cryofuel concentrate, especially the clear stuff is usually pretty amazing. Ive gone through the full gambit of using pastels and various other cool looking coolants, only to time after time get fed up with the level of maintenance, gunk/clog build up, and staining those products are known for.Anyways to TLDR my recommendations for better coolant options, go get yourself some koolance 702 high performance liquid coolant.Reason being that there are far too many hurdles and problems with other products when combining different water cooling parts/metals. You will likely run into products that are labeled as one metal but are actually just coated in that and can quickly corrode and become problematic.Koolance also provides ample information for everything, like the fact that its meant to last for multiple years in a water cooling environment without the need to completely replace the liquid. Just keep the coolant topped up essentially.Id still recommend swapping out all the coolant though at least once a year to be safe.Just remember no silver if you have any nickel parts. No aluminum, just no never, never let that stuff near your loop.
