What buyers said
Left by people who bought this part here. Compatibility reports are the useful ones — if you installed it, say which board.
Three steps, in the order that matters. The one people get wrong is the first.
01
Confirm the hardware
>Custom liquid cooling loops using standard G1/4 fittings — the exact model, not the family. Partner boards differ.
02
Mount it dry
Thermal interface material as supplied. Even mounting pressure, correct bracket orientation, no over-torquing.
03
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 part
Answers specific to B-L2-4BM-X-V2. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.
What does this part fit?
It is machined for >Custom liquid cooling loops using standard G1/4 fittings. These are machined to a specific hardware layout, so confirm the exact model rather than the family before ordering. Part number B-L2-4BM-X-V2.
Is it in stock, and when will it ship?
It is a normally stocked item currently on pre-order — we are between shipments. Orders dispatch from Boise, Idaho within 20 business days, and pre-orders are filled before any stock goes back on the website.
Can I cancel my pre-order?
Yes. A pre-order can be canceled any time before it ships, for a full refund. Nothing is committed until it leaves Boise.
Will I pay import duties or customs charges on delivery?
Not on a US order. US import duties and tariffs are already included in the price, so nothing is collected at the door and there is no brokerage fee. Orders shipped outside the US may owe that country's customs fees and duties.
Who handles the warranty?
PrimoChill, from Boise, Idaho. Every claim is handled directly by our support team rather than returned to an overseas factory. Installation is at your own risk: we are not responsible for leaks or damage to other hardware.
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?
A water block is one component of a loop: you also need a pump, a radiator, fittings, tubing and coolant. If you are starting from nothing, an AIO or a distro-plate kit is the shorter route — ask and we will spec it.
Ask us before you order
Send your exact hardware model and we'll confirm the right part before you spend $34.99 — 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.
