PrimoChill PrimoPrep - Cooling Loop Pre-Treatment
About this part
Since making our first coolant in 2002, PrimoChill has always strived to make the coolant usage as simple and reliable as possible. A lot has changed in the water cooling industry since than, but one thing has stayed the same and it is our drive to make products better and easier to use as well to maintain.
Primochill PrimoPrep was developed to address some of the most common issues that plague the computer water cooling industry. The mixes of metals in water cooling, from nickel plating to raw copper and everything in between has always made some coolants not as reliable and simple to use.
PrimoPrep's unique formulation pre-treats your cooling loop to ensure compatibility with today's high performance coolants as well as those incredible "Showcase Coolants". The pre-treatment helps control the fluctuation of the PH levels in your system caused by high levels of copper mostly from large capacity radiators. With this treatment it also prepares the system for use of coolants in a mix metal closed loop environment leaving the guesswork a thing of the past.
What buyers said
Left by people who bought this part here. Compatibility reports are the useful ones — if you installed it, say which board.
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.
