LIQ-702BU-B Koolance 702 Liquid Coolant, High-Performance, UV Blue, 700ml (24 fl oz)

Been using this brand for years. Kept my water pump in my pc running since 2008. Just recently replaced the pump due to concern it's gonna give out sometime, but to have a pump run 16 years, pretty good stuff. Also does a great job cooling my pc.

Updated review: I am going on 4 years now with this coolant in my custom loop. It looks and works amazing still!!!! There is nothing in the lines visibly, no gunk, and ive only had to top it off once or twice with very little fluid.

This is a great alternative to buying the bulk jug. It's enough to fill resevoir and lines on EX2-1055 custom loop system.

So far, so good. I bought two Thermaltake Pacific RL-240 kits for my build. They both came with Thermaltake coolant, but I wanted a coolant that was UV reactive. This stuff looks super cool at night lit by a string of UV lights in the case. I bought red and blue and they both look good. The red is a little more opaque than the blue, but clearer than the Thermaltake red. They are 700ml, so I needed 1.5 bottles of each for my build. I'm guessing builds with smaller rads and or less pipe one bottle would do the trick. All of my runs required the longer 1 meter tubes because my case is so big.

Excellent coolant! I have been using this coolant for a few months now in the build in the pictures. I recently drained my system to swap out the GPUs and there was absolutely no residue or anything in the blocks. This stuff didn't even stain the tubing. Everything cleaned off perfectly, I was actually amazed. If you would like to add some color to your coolant, it can be risky, but I feel that you will be safe with this outstanding option!
