What installing it actually involves

Three steps, in the order that matters. The one people get wrong is the first.

01
Confirm the hardware

Match your exact model against the compatibility notes, not just the product family.

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.

Water cooling parts are designed for self-installation by qualified users. Damage caused by installation error isn't covered — if you're unsure at any step, ask before you power the loop.

Questions people ask about this part

Answers specific to B-RAM-D4-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?
Compatibility for this part is listed in the compatibility notes on this page. Bykski machine to a specific hardware layout, so send us your exact model and we will confirm it against part number B-RAM-D4-X-V2 before you order.
Is it in stock, and when will it ship?
Yes — only 5 left in Boise, Idaho. Orders placed before 2:00 PM MST on a business day ship the same day — we do not ship weekends or US holidays. Overnight delivery is available at checkout.
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.
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?
BYKSKI.US, the exclusive US distributor, from Boise, Idaho. Claims are handled domestically rather than returned to an overseas factory. Damage caused by installation error is not covered.
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 $47.99 — 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.
