PrimoChillOpaque Computer WaterCooling Fluid - Pre-Mix (32oz) - UV Green

God this product is TERRIBLE. I would put negative stars if I could. I had this in my custom loop for less then a month, and it gunked up ALL my parts with this nasty residue. The gunk caused my water flow to be very minimal. Not to mention I was getting 80c+ temps with this stuff in my pc. It would have fried my CPU if my motherboard didn’t have automatic CPU over heating protection. I had to take everything apart and clean it all out. Then ended up replacing it with distilled water with a premix additive and coolant dye. My temps went down 30 degrees while under load. Sitting at around 50C while playing games now. Instead of the 80 - 90C I was getting and having my pc overheat and shutdown.Do not buy opaque coolant ever, from any company. That stuff sucks and will permanently ruin your pc if you keep it in for a long time. Used distilled water with premix and color dye if you want the great effects of water cooling and still have the cool colored coolant. Transparent Coolant will always be superior.

I ran deionized water for a week before I added this I’m running full nickel plated waterblocks ek cpu bits power ram-GPU two black ice radiators and an ek disto plate running on the lowest flow setting to the point were my flow indicator doesn’t spin because I’ve noticed most people with high rpm pumps are having issues with the fluid breaking apart and messing up the loop I’ve been running it for 3 months and it’s still as purple as the day I put it in.

When I put this in my system the cobalt looked amazing with all of my lights and I almost made a 5 star review just based on that. I’m glad I didn’t. I turned on my computer last night and the fluid was almost clear! All of the particulate that makes it opaque had settled and is now in various parts of my system. I’m going to have to put a lot of work into taking literally everything apart and cleaning it and spend more money on a different coolant. I was thinking about trying Vue but now I’m scared with how this one turned out. Definitely do not buy this.

Great coolant, amazing temperature performance. And it just looks awesome! Very happy with purchase

It broke down within a week. Same metal loop and followed the instructions and it did not last 1 week.

Delivery was very fast but does not have slower, free option. Does react to UV but not impressively reactive imo. Comes with free bottle of sysprep which I didn't initially know I needed so that was definite plus.

The media could not be loaded.  I built my pc using 2x 360mm radiators, while cooling both gpu and cpu, and still had some left over. Colors will lighten just a little when heating, but it’s a cool color.

This is a solid yellow that looks great in the clear solid tubing running threw the case with RGB lighting
