## Description

This product is a professional design tool that provides simple and practical use to perform the right task.

Review: Works great - Added to brand new loop with all EK parts. The radiators were precleaned with distilled white vinegar and distilled water. Everything else was rinsed with distilled water prior to installation. I have been running the coolant for a month and I have had no problems in my loop. I made sure to look in the bottom of the bottles before I put it in my system and I saw no evidence of sediment in the bottles I received from desertcart. It is a nice transparent red color. It is not UV reactive but when I change LED fan colors the color of the coolant changes so it provides for some cool effects while not looking over the top. Nice to have a hassle free solution which contains all of the additives your loop needs to resist corrosion and buildup. You can definitely count on EK quality which is why I went with this over some of the other junk out there. I had considered the particle fluids like Vue and mayhem aurora but they basically seem to be a giant hassle and only a temporary show solution not for long-term use. Update : I have been running his fluid in my system for six months I probably run the computer an average of two hours a day. I’ve had zero issues. No buildup or other residue in the loop. Everything is working great. I’m gonna let it go another six months before I clean it. Update 2/26/21 still on the original fluid haven’t had to clean the loop. Loop looks pristine with over 1 yr run time on the original fluid. Very pleased. Update 9/6/21 , Still on the original fluid Without a single cleaning since originally putting the fluid in. The loop looks perfectly clean. The copper water blocks look good, no discoloration or other problems . So far it seems that the fluid has maintained its original red color without significant degradation..
Review: No buildup, rich colors, cool temps - I decided to take a chance on some colored fluid for my custom loop a couple of years ago, and have been using this EKWB CryoFuel exclusively. I've had no build-up and great performance. I am changing my fluid every 6-9 months, and have had no problems at all. Based on forum recommendations, I've stayed away from the opaque/milky colors and stuck to clear colors like blood red. This looks great and worked out very well for me.

## Questions & Answers

**Q: Does this need to be mixed with anything like distilled water or is running just the coolant good enough?**
A: It's a premixed coolant, not a concentrate, so you don't have to mix anything. Just pour it into your loop and you'll be set

**Q: Is this coolant safe to use with bitspower petg tubing?**
A: I am currently running it in my wife build, using PETG tubing.   The coolant has been in there for over 6 months now.  I havent noticed any issues at all with it.

**Q: is it ok to keep this coolant in the loop for 2 years before change?**
A: To keep your system clean from any minerals building up in your blocks and loop you should flush and clean and inspect every 6 months and check your system radiators and components like reservoirs and pump o-rings to be sure they are not getting too much build-up aka white cloudy slime. If you do this your system will last and last and last without having to replace you're Loop components. as to the two years, that's the unused product shelf/storage life remember to keep your unused coolant in a cool dry dark location until you're ready to use more.

I hope this fully answers your question.

**Q: Is this compatible with pvc soft tubing?**
A: I don't see why it wouldn't be. Just remember that ALL soft tubing eventually gets a 'haze' in it from these coolants with a 'solid' in them. I personally haven't seen any residue or deposits after almost 3 months in use, but they do recommend that this fluid is drained every 6 to 12 months depending on your usage or probably if you notice residual deposits forming. Seeing that this is more of an on the clear side coolant I'd image that that haze wouldn't form as quickly as using other 'hard' solid filled coolants. The only way you'll know for sure it to run it and see how the tubing holds up to it.

### ⭐⭐⭐⭐⭐ No loss of color and does as intended
*by L***N on November 10, 2021*

Been using it for almost a year now and the color has remained the same the whole time in a computer that is used on a daily basis. It's great to have coolant that looks just the same as the day I poured it. Was one of my chief concerns and hasn't been an issue. Kept my computer running nice and cool so no complaints here!
