Questions about this item

How do I install the ADDA AB5605HX-Q0B cooler in a Sony Vaio PCG-31311, and which step is often missed?

Remove the bottom case, disconnect the old fan cable from the motherboard header, swap the heatsink assembly, then reconnect the cable before reassembling; the step most people miss is plugging the fan header back in.

Clean dust from the heatsink fins and fan blades every 6–12 months using compressed air; replace the unit if bearing noise appears or airflow drops noticeably.
