EKWB EK-CryoFuel Concentrate PC Coolant, 100mL, Clear | Premixed, ready to use PC coolant with corrosion and algae inhibitors, Clear finish, 100mL capacity

Usually use premix but this stuff is working great

👍🏻

Cleaned my Full tower's CPU/GPU water system and then added EK-CryoFuel as a lower cost replacement alternative to my original brand, and at the initial startup priming, it found additional impurities the system cleaning process missed! Tore the entire system down to find out if any corrosion existed due to this "new brand" -none! Then checked all of the tubing- and they were also fine, and all of the connections were fine. (Having lost one system to corrosion, makes a person slightly anal from that point on.) Conclusion: It had found what my yearly cleaning had missed. I recommend this product.

once again watch jaystwocents or ltt linus tech tips before doing a water cool pc.

Use this in my closed loops as I don't like using pastal or opaque dyes in my loops. Does its job for both algea growth and anti corrosion. One thing I noticed is that once mixed your distilled water has a strong chemical smell but obviously its a chemical. This is my go to for watercooling , haven't tried many others since my results have been so good with ekwb.

No build up at all. Very clear, paired with plain distilled water. Everything is chilly and clean. Works perfect. Specs, if you want to know, doubt it though. 3950x, 2 x 5700x’s with EK water blocks, EK SE rads, Thermaltake 16mm OD PTFG tubing, EK fittings, X570 AsRock Aqua 239/1000. Corsair pump and fans,

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.

This is the 4th time I've bought this stuff in various colors and it just works!!

EKの透明感が好きで愛用してます 何時もは、そのまま使えるヤツを使ってますが品切れで 濃縮タイプをチョイスしました 使用は問題無いですね 表示通り1:9、1L作ったので本商品1本に精製水900mL 人にもよりますが配合作業が手間でなければ割安です

Does exactly what you expect, I have a full EK custom loop with metal hardline, I contact EK prior to a lot of the build to make sure I wasn't going to get metal contamination from the metal hardline and adding this just makes life a whole lot better when it comes to maintenance time. You should always have this or something like it in your system.

Benutze das Zeugf seit 3-4 Jahren, bislang keine Probleme - Wasser bleibt kristallklar

Its hard to tell came back to me in a year or two. Then i can tell you

色が付いていない方が水質の変化や異常に気付き易いのでこれしか使っていません。 ただしこれを書いている2025年5月現在、日本では手に入りにくくなっています。EKWB公式でまとめ買いした方が良いかもしれません。
