Thermaltake C1000 1000ml Pure Transparent Pre-mixed Clear Coolant Cooling CL-W114-OS00TR-A

Though the description says this is a concentrate that makes 1000ml of coloring, that would be more clearly written as it makes 1000ml of colored liquid. I would have ordered more if I'd understood that, but I don't have any particular complaints. I added this dye concentrate to a 2 gallon reservoir of distilled water used to supply a water cooled CNC spindle. It added a light blue tint, and I'll probably purchase another bottle of this to try for a more vibrant tone in the water lines.

This is exactly what I was wanted. The color was kinda clear but definitely green.

Great stuff! I've been running it for over a year, just reflushed the system and the system looked good. Didnt notice any impurities anywhere, I recommend it.

Works really well and prevents corrosion, but the downside is that this does leave residue build up in your cooling loop if used for prolong times. Recommend changing this stuff every 6 months.If you ever get a leak or spill it somewhere the fluid will either crystalize or leave a white residue on the surface.I just wish this came with screw on tube to make things easier and create less of a mess. So be prepared to use a funnel or vehicle syringe with a hose attachment.Overall this is a great product and keeps temps cool.

One vial will last forever. I put in only a few drops in the past. Started with a 240 cl radiater, than added a 360 on top of that. Siphoned out about half my coolant (c1000) for 3 times of upgrading. Had a leak on that last bit so had to re-think my tactic. Speaking of which, much easier to see with a little added color lol. No idea why everyone is having issueswith this stuff when it comes flushing.The way I see it, it only takes one time to get it right and prove the FORMULA itself is not what's screwing everyone. In a sense, it's a lot like taking your car into shop. Don't matter what company it is, just the locals and their honesty. I hardly flushed my loop, more like trickle distilled water for a few secs. Been running fine for a couple years and no stains so far.

Super bright Green UV dye. I love the look of it, its easy to flush clean also. I use quite a bit of it in just some distilled water and it works great.I flush my loop about every 4-5 months just for upkeep, but I have never seen any sediment or anything suspect come out when I flush it. I then run a gallon of distilled water until it is clear again, then add the dye again.

I serviced my water loop in my PC and used this to refill the system. it really is crystal clear. it's so clear it showed me that some of the lighting in my system aren't producing white. I'll probably add some UV dye to my loop just for fun.

When I bought this coolant a couple of months ago, it was just what I needed and worked perfectly. Yet, there was no warning that this product was recently discontinued by Thermaltake. When I went to purchase another liter for future topping-off and/or other cooling system builds, I found it no longer available except via third-party sellers at exorbitant prices.Thus, 5 of 5 stars but don't buy.
