Replacement Cooling Fan for SUNON MG45090V1

This new DBTLAP cooling fan matches the SUNON MG45090V1-Q000-T99 4H1RR specification. It operates at 5V and draws 0.29A. The package includes one fan unit. Buyers should verify the part number against the original component before ordering to ensure 100% compatibility.

Direct-fit design simplifies installation

The fan is built as a like-for-like replacement for the specified SUNON model. Its connector and mounting points align with the original laptop chassis, so no adapters or modifications are required. Photographs supplied by the supplier show the exact item; comparing these with the existing fan confirms fitment before purchase.

Low-power operation keeps noise and heat in check

Running at 5V and 0.29A, the fan draws minimal power from the laptop's supply. In normal use it maintains component temperatures without adding noticeable acoustic load. The low current rating also means less strain on the motherboard fan header during extended sessions.
