Powerex MH-C980 Disassembly

Introduction

Hello, this is a partial teardown of the PowerEX MH-C980. The OEM fan was too loud for me so I took it apart to investigate.

    • Take the bottom plastic cover off. It just comes off, no tabs or any glue. Remove the fan cable from the main board.

    • Remove fan by removing the adhesive tape from the fan cable. Then remove the 4-rubber feet stickers holding the fan into the bottom case. Then pull the fan out. Fan PN is FD-4007HH12C. Made by Titan.

    • Fan measures 40x40x7mm. Takes 12V at 0.18A. 2.16 Watts. RPM of 6500. 7.68 CFM. 0.11 INCH-H2O. <28.7 NOISE (DBA).

    • There is not room for a 10mm tall fan due to the electrical contacts that come out of the bottom of the board. The only other fan that might work is a 6mm tall fan from Orion Fans (PN OD4006-12HSS)

    • Charger seems to work just fine without the fan installed, but then the components and your batteries may get hotter than the OEM intended. (fan was too loud for me).
