What this works with

Check these against your build before you order. If anything here does not match what you have, ask us first — it is cheaper than a return.

  • Do not mix ANY additional additives, coolants or silver coils, or different colors of True. This will change the formulation of True causing undesirable results, including sludging and breaking apart.

Color not right

I ordered the violet and when I mixed it in a gallon of water it now looks like a dirty brown. Not happy but i can't sent it back now.

Excellent Coolant!

I purchased the Sky White and followed the recommended procedure for cleaning/filling along with running System Soap in system. I also disassembled by cpu and gpu block for extra cleaning. Loving this fluid!!

Great Coolant!

This stuff looks amazing in my system. It reminds me of the ooze in the 1991 TMNT movie The Secret of the Ooze. I'm only giving it 4 stars as the UV reaction isn't great. I'm going to try using their Brite Green UV intensifier with this and see if that helps. Keep up the good work PrimoChill!

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.
