Replacement CPU and GPU cooling fan with heatsink for MSI GS66 Stealth models

  • Accessory TypeFan
  • Cools CPU and GPU with integrated heatsink
  • 4-pin connector enables precise PWM speed control
  • 5 V operation draws minimal system power
  • Designed for MSI GS66 Stealth MS-16V1 models
  • New condition ensures reliable out-of-box performance

Direct replacement part

This is a new CPU cooling fan with integrated heatsink built for the MSI GS66 Stealth series. It matches the MS-16V1 chassis used in the 10SD, 10SE, 10SF and 10SGS models. The assembly is intended for owners or technicians servicing those specific laptops.

Four-pin 5 V power interface

The fan connects through a 4-pin header that supplies 5 V for speed control and monitoring. That connector layout is fixed by the motherboard design, so the part cannot be adapted to 3-pin or higher-voltage headers. Buyers must verify their board uses this exact pin-out before ordering.

Factory-specification build

The unit carries the manufacturer's 6-month warranty and uses the original MPN references E322500600A87 and E32-2500600-A87. Mounting points align with the existing screw pattern on the MS-16V1 thermal module, allowing a straight swap without modification.

Questions about this item

Which GS66 Stealth model matches this MS-16V1 heatsink?

It fits the GS66 Stealth 10SD, 10SE, 10SF and 10SGS variants that share the MS-16V1 chassis.

What does the 5 V rating mean once the fan is installed?

The fan draws 5 V from the motherboard header, so it runs at the speed curve the laptop firmware provides.

How does the 4-pin connector control the cooler?

The fourth wire carries the PWM signal that lets the system vary fan speed based on CPU and GPU temperature.
