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.
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?
- 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.
