CPU GPU Graphics Cooling Fan Replacement for MSI GS63VR GS73VR - Quiet

In this review of the CPU GPU Graphics Cooling Fan Replacement for MSI GS63VR and GS73VR Stealth Pro laptops, the bottom line is simple: this OEM-style pair is for owners who need a direct, functional replacement for a noisy or failed fan assembly. The pack includes one CPU fan, one GPU fan and two tubes of thermal grease, and it matches the documented part numbers used in many GS63VR and GS73VR MS-16K2 and MS-17B3 configurations. If a loud fan or thermal throttling is the primary problem, this replacement is a practical repair option that fits the original heatsink and uses the same 4-pin wire-to-board connector.

Key Features

• Direct compatibility: Designed to match the factory layouts used on GS63VR and GS73VR Stealth Pro MS-16K2 and MS-17B3 series so installation attaches to the existing heatsink without modification.
• OEM part numbers: Comes with the CPU and GPU fan part numbers listed (BS5005HS-U2F1 and BS5005HS-U2L1) so buyers can confirm a correct match before ordering.
• Complete pack: Includes one CPU fan, one GPU fan and two thermal greases so users can replace both fans and refresh thermal interface material at once.
• Standard power spec: Fans run on DC 5V at 0.5A (4.5W) with a 4-pin connection, maintaining the original power and control behavior of the laptop cooling system.
• New condition: Sold open box but brand new and unused from the OEM factory, which means replacement parts are not pulled or refurbished.

Who It's For

This replacement is aimed at MSI GS63VR and GS73VR owners who are experiencing loud fan noise, failing fan bearings, or thermal issues and who are comfortable opening the laptop and completing a hardware swap. Technically minded users and repair shops will appreciate the included thermal grease and the matching part numbers for an exact fit.

Users who are unsure of their laptop's internal configuration should check the existing fan part numbers and connector type before buying, because the GS63 and GS73 models were offered with different internal fan configurations and this pack only fits the specified MS-16K2 and MS-17B3 series variants.
