Check the header before you plug it in

This part is 5V 3-Pin ARGB. A 5V ARGB header and a 12V RGB header use the same physical connector and are not interchangeable — plugging this into a 12V header destroys the lighting, and that is not a warranty defect. If your motherboard header is not labeled, ask us before connecting it.

What buyers said

Left by people who bought this part here. Compatibility reports are the useful ones — if you fitted it, say which board.

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.
