About this part

Primochill System Reboot was created to address the need to prepare/clean existing cooling loops AND be able to clean out old dyes that may have leached onto components during previous usage. Similar to Sysprep this flush style solution will cleanse out any debris/residue leaving your water cooling loop clean, clear, pristine and ready for any type of coolant. The beauty of ReBoot is it's ability to pull color from stained components.

Good Stuff

Was good quality and on time as always. Would buy again.

Good preventative measure!

I like to run reboot in my systems before adding new coolant. I think it is a good idea to flush your system with at minimum distilled water before changes, but it's a better idea to run a loop cleaner like this to help remove anything that might have built up.

Solid price and shipping is always fair and quick!

I have purchased probably 10 of these and will keep doing so as long as I'm liquid cooling.

It never fails. I love this stuff!

This is my second time using this product and it just doesn’t disappoint. Nothing to it, follow the directions to a perfect T. Again it doesn’t leave everything 100% sparking clean but it definitely cleans and lifts any debris that’s stuck on tubing or reservoirs. I personally use glass reservoirs and tubing and I’m always just so satisfied with the outcome.

Amazing Stuff in that bottle

I have used System Reboot on my rigs for years and it is the only way I service my PCs, save me so much time and effort on keeping my blocks clean

AMAZING!

second time ordering this stuff. did a couple flushes of distilled then filled the system and let let it run for 2 days (used then put a dummy cable on at night so it can run non stop) had a nice white film from opaque fluid. once i was one i flushed it out and my loop was crystal clear! flushed with distilled water, in goes the Primo Prep then back to opaque.

love this stuff. you take care of your loop and you never have the nightmare stories you see on the internet. Great product and even better comany!

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.
