Who Should Buy This

Buyers needing a cooler for a different laptop brand, a different LG chassis, or a passive cooling pad should look elsewhere. Compatibility is limited to the specific models and part numbers shown in the listing.

Critical Specification

The decisive specification is the exact part number FM7Y DFS531005PL0T with 5V .5A rating. Verify this number against your current fan before ordering, as LG uses different coolers across similar-looking 17-inch chassis. No other specification determines fit.

Questions about this item

How noisy and hot does the 5V .5A fan get when it runs all day?

The fan is rated at 5 volts and 0.5 amps, so it draws very little power and stays cool during continuous use.

What must I already own for this fan to fit and work?

You need an LG laptop matching one of the listed models such as 17U790 or 17UD790 with the FM7Y or DFS531005PL0T part number.

Will this replacement fan work alongside the original heatsink and motherboard in my older LG 17UD790-PX56K?

Yes, it is a direct replacement for the CPU cooling fan in those specific LG 17UD790 series models.
