The package contains only the fan assembly without heatsink, mounting screws or thermal compound. Anyone needing a complete cooling module should look elsewhere.

Four Pin Connector Specification

Questions about this item

How do I confirm the 4 PIN fan is working after installing it in my HP Probook 4430s?

Power on the laptop and listen for the fan spinning; the BIOS should report normal RPM and temperatures should stay within typical operating ranges for the 4430s series.

What comes in the package and is any extra hardware needed for the KSB0505HB-BG38 replacement?

The box contains 1 x Fan only; no additional screws, thermal paste or cables are included, so reuse the original mounting hardware from your Probook 4330s or 4436s.

Which part number matches my HP Probook 4331s — 6033B0024901 or 646358-001?

Both numbers reference the same 4 PIN cooler for the 4331s, 4435s and 4436s models; verify the label on your existing fan matches either code before ordering.
