Dell 15 5580 Compatibility

This replacement cooler fits the Dell 15 5580 laptop series. It is intended for owners who need to replace a worn or noisy original fan. The part arrives new and ready for installation.

Part Number Verification

The critical specification is the part number AT1SE0020SL with alternates 378CK, 0378CK and cn-0378CK. Buyers must confirm this exact code against the original heatsink to guarantee fit. Without a match the cooler will not align.

Straightforward Swap

Installation follows the standard Dell 15 5580 disassembly routine; the package includes one fan unit only. Common issues arise when the part number is not verified beforehand or when thermal paste is not reapplied during reassembly.

Questions about this item

How does this cooler fit the Dell 15 5580 once installed?

It is built as a direct replacement fan and heatsink assembly for the Dell 15 5580, matching the original mounting points and thermal layout so it seats without modification.

What connector does the fan use and what does that limit?

The unit uses the Dell 15 5580 proprietary fan header, so it only works with that motherboard pin-out and cannot be adapted to other laptop models.

What clearance and screw pattern does the heatsink need inside the chassis?

The heatsink follows the Dell 15 5580 internal bracket spacing and screw-hole pattern exactly, requiring the standard chassis cut-outs for the copper pipes and fan housing.
