Before you install it

This kit is the plumbing between your parts, not the loop itself. Plan and dry-fit every run before you cut or bend, and whatever the build, the last step does not change: 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.

Questions people ask about this kit

Answers specific to N0000035S00. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

What's in this kit?
Everything listed under What's in the kit at the top of this page, with the fittings in the finish you choose. Each line links to that part on its own, so you can add spares or a second pack.
What else do I need for a loop?
The kit covers the tubing side: the tube, the fittings and the tools to cut and bend it. You still need a pump and reservoir, a radiator, water blocks and coolant. The Build planner works out the rest from the parts you have.
Can I return it if it turns out not to fit?
Yes. Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used. So we would rather check the fit with you first: send us the model and we will check it against this part.
Who handles the warranty?
PrimoChill covers this part for 1 year. Every warranty claim is handled directly by our support team, so you deal with us from start to finish.
Is shipping free?
Shipping is free on orders over $125 to addresses in the lower 48 US states.
Are printed instructions included?
No printed manual is included. Installation references are in the product gallery images, and the install guides on this site cover the process step by step.
Do I need anything else to use it?
Check the parts list above against what you already have. If you are building a loop from scratch, send us the full parts list and we will tell you what is missing before you order.

Ask us before you order

Send your exact hardware model and we'll confirm the right part before you spend $99.99 — or tell you honestly that this isn't the one.

Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used.
