EKWB EK-CryoFuel Lime Yellow Premix, 1000ml, PC Liquid Coolant, Water Coolant

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.

love the contrast of the color nice and blood like.

I ran the green color for about 2 years,in a Corsair Hydro X Series XD5 RGB cooling only a 2080ti( 28c-42c) changed to orange. It left a hint if green but cleared out after a good system flush now cooling a 3080ti at 44c.

Very clear and wet

What more to be said add it to your system and forget about it for a year and change it out. ( Or at least that's my plan might try for longer not sure need to check how long it should last.)

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 Amazon. 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..

The product has a 2 year shelf life once bottled and should last 1 year once installed. The bottle I received had less than 1 year remaining since bottled. Otherwise no issues.

used this stuff for the past year. fluid hasnt changed one bit, and has not damaged/discolored any of my acrylic tubes. I have only used the premix, not the concentrate. just built a new rig, and bought this stuff again for my new loop.

Have ran this coolant for the past year. Whole system is clogged up with a white residue and it has added a chalky film to all the tubes. Have had to re-bend new tubing, dismantle and thoroughly clean everything. I noticed one reviewer wondering what could go wrong as it’s only "clear fluid". They have some nasty stuff in here that isn’t brilliant for the loop. Use xspc clear or mayhems. Or, distilled and biocide. Even straight up milk would be better than this tosh.

I've used this a few times since moving over to water cooling on my main PC, I've tried those pre-mixed colour ones but they leave such a nasty residue behind, and there is no way to remove that completely without changing all the water pipes, this one leaves nothing behind.This is one of the best coolants that I've used, always better if you have a lot of RGB connectors to show off as this liquid will bring the wonderful colours to the forefront.This leaves none of that nasty residue behind like some others can, and it certainly won't colour your pipes that nasty colour that is added to lots of others also.It is quite pricey, but I think you get what you pay for and will last for quite a while before you have to change it, they do recommend every 6-12 months.I hope you like my review, Angie x

This stuff is junk. This was a new system. Flushe dour many times with distilled water and then ran the pump with distilled for a few hours.Drained it and added the EK clear. Instantly I noticed it was a bit milky. It was too late by then to do anything about it.Noticed the date was Dec 2020 and it was also out of date. Come on Amazon this shouldn’t be happening.

I bought 2 of these (2L total) incase I needed more than 1 to fill my loop. I did not, but it is good to have a spare, I suppose (?) Incidentally I have 240/360 radiators (30 and 45mm depth), GPU/CPU blocks and 120 reservoir.The clear mix is nice because it means you don't have the risk associated with pastel/coloured mixes to do with clogging/gunking up your loop. And with RGB you can have any effect you want, without the coolant colour predetermining your colour set-up.

After 9 months the white colour fades away and it starts to look like transparent, the product gets stucked inside the hardware components like hard water moldong on shower, I have been using the clear coolant from same brand and its still holding well, coolant still clear and the temperature stays similar, but the cooling quality starts to degrade after 1 and half year, which is not a problem at all. If we our body requires shower 3-5x a week then your water cooled Pc definitely does too, so once a year is a good idea :) then you don’t t have to go through the struggle of cleaning junk deeply. Hope it helps ‘_-
