Questions about this item

Which CPU sockets must my motherboard have for the Pro 240 ARGB block to mount?

The cold plate fits AMD Socket AM4, AMD Socket AM5, Intel LGA 1700 and Intel LGA 1851 without extra brackets.

Will the 277 mm radiator and 120 mm fans fit in a case built for 240 mm AIOs?

Yes — the 277 mm length matches standard 240 mm mounting holes and the two 120 x 120 x 25.4 mm fans use the same screw pattern.

How can I confirm the pump is running at its rated speed after installation?

Connect the pump header to a PWM fan port, then check BIOS or monitoring software for a reading between 1200 and 3200 RPM.
