EK Water Blocks 3831109813263 PC Fan (Processor, Cooling Set, Red, Transparent, 5-60 °C)

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..

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.

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!

Fast shipping and no hassle.Pre mix is easy to use and keeps its color even after 1.5 years.A warning for first time water coolers, It will stain fabric if you are messy (as all dyes tend to do)

Looks great in my PC

I’ve used this for 6 month because jayztwocents said try to change every 6moths because of the color it can get stuck especially the darker colors but to my surprise once 6 months has passed there was like almost no gunk and was still clean I still changed just to change it cause I wanted to do a deep clean I had already taken almost everything apart and as for effectiveness for cooling for me personally it might cool better than the distill water I have now because I used to get temperature 38-48 and with distilled it’s like 42 45 or 52 and this is idle not hot for me personallyMy cpu and gpu are in the same loop I have 3 rads all of them 360 and my CPU is a ryzen 9 3900x and a 2080ti

This came two days before the factory wire on my DDC pump sheered off due to an aggressive crimp. That required me to drain the loop and disassemble the glass tubing to fix. Total serendipity.It looks like my temps are nearly a degree celsius cooler, but lots of things could affect that. It stains any paper towel and fingers that cross its path.Microbubbles - They're still working out of the system, but there is hope they will not remain.

Got this to refill my closed loop water-cooling system in my computer after loop servicing\upcoming new graphics card install. Since I built it using EKWB parts (except the 2 radiators) I used the EKWB concentrate the 2 times prior (initial build & the 1st annual service flush\refill afterwards) which works well (had no growth or buildup in system or blocks) so this time I wanted to go w\ the pre mix version. Good price for an excellent product!
