What this works with

Check these against your build before you order. If anything here does not match what you have, ask us first — it is cheaper than a return.

  • Standard 120mm mounting — 120mm case fan positions and 120mm series radiators
  • 26mm thick, not the usual 25mm. Check clearance in slim builds and in sandwich-mount radiator positions
  • Requires a 4-pin PWM fan header for speed control and RPM reporting
  • Requires a 5V 3-pin addressable RGB (ARGB) header for lighting
  • This fan does not connect to a 12V 4-pin RGB header. The connectors look similar and the voltage is not. The LED plug is keyed with a blanked position to prevent it, but forcing it will destroy the LEDs
  • The fan will run normally on PWM alone if no ARGB header is available; only the lighting is lost
  • No ARGB pass-through — each fan needs its own header position or a separate splitter or hub

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.

About this part

The Bykski 9-Blade High Volume 120mm Fan is a PWM case and radiator fan with 5V addressable RGB lighting, built around a dual ball bearing and a high-precision bearing shaft core.

Nine blades and a 2000 RPM top speed give 70.33 CFM at 37.7 dBA. PWM control means the motherboard scales the fan to actual load, so it spends most of its time well below both of those figures and only reaches full speed when the system is working. The blade geometry is shaped to move air through resistance — radiator fin stacks, dense heat sinks, filtered intakes — rather than only across open space inside a case.

Dual ball bearings are the reason this fan is rated for sustained running. Sleeve bearings wear faster when they run continuously or mount horizontally; ball bearings trade a small amount of noise for a longer service life, which is the right trade in a system that stays on.

Lighting is 5V addressable RGB (RBW) on a standard 3-pin ARGB header, so each LED is controlled individually by your motherboard’s own lighting software. No proprietary controller is used, and none is included.

Questions people ask about this part

Answers specific to CF-RBW2000EX-X. 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?
This part is specified by what it connects to, not by a card model:
  • Standard 120mm mounting — 120mm case fan positions and 120mm series radiators
  • 26mm thick, not the usual 25mm. Check clearance in slim builds and in sandwich-mount radiator positions
  • Requires a 4-pin PWM fan header for speed control and RPM reporting
  • Requires a 5V 3-pin addressable RGB (ARGB) header for lighting
  • This fan does not connect to a 12V 4-pin RGB header. The connectors look similar and the voltage is not. The LED plug is keyed with a blanked position to prevent it, but forcing it will destroy the LEDs
  • The fan will run normally on PWM alone if no ARGB header is available; only the lighting is lost
  • No ARGB pass-through — each fan needs its own header position or a separate splitter or hub

Check those against your build before you order. If anything does not match, ask us first — it is cheaper than a return. Part number CF-RBW2000EX-X.

Is it in stock, and when will it ship?
Yes — in stock 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. 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?
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 $18.99 — 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.
