Replacement CPU Cooler Fan

This new DBTLAP cooling fan replaces the original heatsink fan in compatible HP Compaq laptops. It matches part numbers 575283-001, 487355-001, AD5005HX-RC1, JBL20 and KSB0505HA-7M54. The package includes one fan unit ready for installation.

AMD Discrete Graphics Models Only

This cooler fits HP Compaq CQ40, CQ41, CQ45 and DV4-1000 series laptops equipped with AMD discrete graphics. It will not fit Intel-based versions of the same chassis or models that use a different heatsink layout. Buyers needing a cooler for integrated-graphics boards should look elsewhere.

Correct Part Number Is Essential

The single specification that decides fit is the exact part number printed on your existing fan. You must verify that your current cooler carries one of the listed codes before ordering. A mismatched part number means the mounting holes and connector will not align.

Questions about this item

Does the fan maintain stable RPM during continuous heavy loads on the AMD discrete graphics model?

The replacement fan is designed to match the original HP specifications for the AMD DSC models listed, so it sustains the same airflow under load.

How loud is the cooler and how hot does the heatsink get after hours of use?

The fan operates at the factory acoustics and thermal profile for the CQ40, CQ41, CQ45 and DV4-1000 series, producing the same noise level and heatsink temperature as the original part.

Which existing laptop components must be present for this cooler to install and function?

The cooler fits the existing AMD discrete-graphics heatsink assembly in the listed HP Compaq models and connects to the motherboard fan header without any additional parts.
