Replacement CPU fan for Samsung R728 R730 R750

This new DBTLAP cooling fan is built to fit Samsung laptops including the R728 R730 R750 R770 R780 and the NP-R730 NP-R780 NP-R780E NP-R780VE models. It replaces the original DFS651605MCOT and KSB0705HA-9J68 parts. Each unit is tested before shipping to confirm it spins correctly.

Connector and mounting must match the original

The fan uses the proprietary connector and screw layout defined by Samsung for these chassis. No universal standard applies, so the replacement only works when the plug pinout and bracket holes line up with the factory design. Buyers who need a different pin count or bracket spacing cannot use this part.

Straightforward swap if the part number matches

Installation involves removing the bottom cover, unplugging the old fan, and fitting the new one using the existing screws. The most common problem is ordering the wrong variant; the listing advises comparing the original fan to the photos and confirming the exact model number before purchase.
