EKWB EK-CryoFuel Premix PC Coolant, 1000mL, Blood Red

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!

It's everything I wanted. The viscosity is a bit less than what water would be which was actually quite nice. The red color was perfect and I love it. My only and I mean ONLY issue is this coolant maintains bubbles FOREVER. I've filled, bled, turned, shook, etc etc etc my loop trying to get all the bubbles out and only recently the bubbles have 98% disappeared. I've had this coolant in loop for about 2 months.

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)

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 personally My 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

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!

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.

Tout d'abord, sur la photo le liquide ressort un peu pale mais visuellement ce n'est pas du tout le cas. Ensuite sur la tenu du liquide, je l'utilise depuis pas mal d'année (5/6 ans) avec une maintenance légère tous les 2 ans (changement de liquide, nettoyage du réservoir, passage d'eau distillé) et si je vois trop de dépot ou toutes les deux maintenance (donc tous les 3/4 ans) je démonte tout les blocs et je nettoie ne profondeur. Aucun dépôt jusqu'ici que ce soit avec du tube souple, du rigide PETG ou rigide acrylique. Lors de mon dernier nettoyage, le liquide avait 3 ans donc j'ai fait un nettoyage complet en profondeur. Pas de dépôt mais le liquide était devenu plus foncé (chargé de particule non visible) mais les blocs était en super état et après un petit coup de brosse a dent sur mon acrylique, tout redevient comme neuf.

GENIAL PERO POR 14.E EN CASA Y ENVIO 24H POR PRIME QUE ES CUANDO YO LO COMPRE. PAGAR MAS ES UNA TONTERIA FUNCIONA MUY BIEN, EN MI CASO EL LITRO ROJO LO MEZCLO CON 2 L DE AGUA DESTILADA. ME DURA MAS ESTA CON EL TRATAMIENTO ANTIBACTERIANO Y DE COLOR. Y FUNCIONA YGUAL QUE ECHANDOLO DIRECTAMENTE. TAMBIEN CAMBIO EL LIQUIDO CADA 6 MESES . Y LO GUARDO EN UN LUGAR OSCURO.

Ok Performance, but had to pay double the price due to customs. Why would they sell to Canada if they aren't taking care of the customs cost.

Jusqu'à présent, j'utilisais de l'eau distillée pour mes circuits, pour son excellente conductivité thermique. Puis, par curiosité, je me suis demandé ce que les fluides spéciaux, si chers, avaient de plus, à part la couleur. J'ai essayé, et ô surprise, le débit est incomparable. Avec l'eau distillée, je n'ai jamais compris pourquoi le débit était si faible. Avec du liquide de refroidissement, j'ai tout de suite compris : la viscosité. Le fluide coule incomparablement plus facilement, et le refroidissement s'en trouve nettement amélioré. En plus, couleur rouge sang, ça en jette, même si c'est salissant :)
