Questions about this item

How loud is the KSB0505HB fan when it runs continuously inside an ASUS K42JR?

The fan is tested individually before dispatch to confirm 100 % operation; its 4-pin connector allows the laptop to regulate speed, so noise stays at the level the original cooling system was designed for.

Which connector must the motherboard provide for this KSB0505HB unit to function?

A 4-pin CPU fan header is required; the replacement plugs directly into the same socket used by the factory fan on models such as the K42J, X42J or A42JV.

Will the KSB0505HB fit the mounting points on an older ASUS A40J chassis?

Yes — the fan is listed as compatible with the A40J, A42J, P42J and the full K42 series, so the screw holes and cable routing match the original layout.
