HP Thermal Module N18E G0 (L57366-001) is a notebook cooling assembly listed for the HP Omen 17-CB0056TX. HP Support Community identifies this part number as a heatsink assembly for the OMEN 17-cb0011nv configuration with GTX 1660Ti graphics.
The fan and heatsink are supplied as one assembly, so the module serves as a combined cooling part rather than a standalone fan. HP’s guidance notes that the appropriate assembly varies with the notebook graphics configuration. This makes L57366-001 a specific thermal module reference for the listed Omen notebooks, rather than a general-purpose cooling component.
