It matches part number DC28000E3S0 and fits models including the 3521, 3537, 5521, 5537, M531R, 5535 and 2521 series. Each unit is tested before shipping to confirm operation. The package contains one fan only.

Suitable for owners of listed Inspiron 15R models

Buyers with an exact model match from the compatibility list can use this part to restore standard cooling performance. It is not suitable for other Dell series, different screen sizes or laptops that use a different fan part number. If your model number is not shown, this fan will not fit and another solution is required.

Direct swap into the existing thermal assembly

The fan installs into the laptop’s current heatsink and motherboard connector without modification. No extra brackets, cables or thermal paste are included, so reuse the original mounting hardware and apply fresh compound during fitting. Verifying the part number against the old fan before purchase ensures the surrounding build proceeds without delays.
