Questions about this item

Does the 140mm frame of the BL129 line up with standard 140mm case mounts?

Yes, the 140mm square frame matches the standard mounting pattern used on most mid-tower and full-tower cases.

Which motherboard headers are required for the PWM and ARGB connections on the BL129?

Connect the 4-pin PWM lead to a CPU or chassis fan header and the 3-pin 5V ARGB lead to a 5V addressable RGB header; do not plug ARGB into a 12V RGB header.

How should I clean the BL129 fan blades without damaging the ARGB diffuser?

Use low-pressure canned air or a soft brush; avoid liquids and do not spin the blades with compressed air to protect the bearing.
