Questions about this item

How do I install the cooling fan pair in my GS66 or WS66 Stealth, and which step is most often done incorrectly?

Remove the bottom cover, disconnect the old fan cables, match each new fan to its CPU or GPU heatsink using the 16V1-G-CW and 16V1-G-CCW labels, then reconnect the DC5V 1.0A connectors before reassembling. The step most often missed is swapping the clockwise and counter-clockwise fans.

What maintenance or replacement will the fan pair need later?

Clean dust from the heatsink fins every few months with compressed air. If bearing noise or RPM drop appears, replace the pair with another BS5005HS-U4Q or BS5005HS-U4J set matched to the MS-16V1, MS-16V2 or MS-16V3 board revision.
