  • Genuine Dell OEM part ensures exact fit for Inspiron 1420 and Vostro 1400
  • Replaces the CPU processor bay door cover to protect the heatsink bay

Genuine Dell OEM Replacement Cover

This genuine Dell OEM part replaces the CPU processor bay door on Inspiron 1420 and Vostro 1400 laptops. It provides direct access to the heatsink bay for maintenance or upgrades. The cover matches the original factory specification for these models. Buyers needing a different chassis size or a non-Dell laptop cannot use this item.

Sustained Protection During Thermal Cycles

The cover remains secure while the system runs under continuous load and the heatsink temperature rises and falls. Its latch design resists vibration from the cooling fan during extended sessions. No warping or loosening occurs across repeated heat cycles. Users who require active cooling ducts or additional venting will not find those features here.

Durable Plastic Construction With Original Mounting

Moulded plastic construction shows only minor cosmetic blemishes such as a small scratch or scuff from storage. The original Dell mounting tabs snap into the chassis without tools or adhesives. Part number DT139 ensures correct alignment with the heatsink bay opening. Anyone expecting a metal reinforced panel or a locking screw mechanism will need a different solution.

Questions about this item

Does the DT139 cover add any fan noise or heat when the laptop runs all day?

No, the DT139 is a passive plastic cover that simply closes the CPU heatsink bay. It has no moving parts and does not affect thermals or acoustics.

What must I already own for the DT139 cover to fit and work?

You need a Dell Inspiron 1420 or Vostro 1400 laptop with the original CPU bay opening intact. The cover snaps into that existing chassis slot.

Will the DT139 cover align with the older heatsink and screws already in my 1420 or 1400?

Yes, the DT139 is the OEM part number for those models, so it matches the original heatsink bay dimensions and screw points exactly.
