PALIT GTX 1660 SUPER 6GB – After driver update, the fans stopped working even under load

Troubleshooting a GPU Fan Malfunction After Driver Update: A Case Study of the Palit GTX 1660 SUPER 6GB

Introduction

Graphics card performance and stability are critical for a seamless gaming and computing experience. However, users sometimes encounter issues following driver updates, which can hinder GPU functionality and lead to overheating or hardware failure. This article examines a real-world scenario involving the Palit GTX 1660 SUPER 6GB and explores potential causes and solutions for a persistent problem where GPU fans cease to operate after updating drivers.

System Configuration Overview

The affected system comprises the following components:

Graphics Card: Palit GTX 1660 SUPER 6GB
Processor: AMD Ryzen 5 4500 (no overclock)
Motherboard: MSI A520M-A PRO
Memory: 2x XPG Gammix D35, 8GB DDR4 at 3200MHz
Power Supply: Corsair CX550 (550W ATX PSU)
Operating System: Windows 10
Current GPU Driver Version: 560.70

Issue Description

The core problem emerged after updating the GPU driver. Post-update, the graphics card’s fans ceased functioning—even under load—resulting in temperature escalation up to 95°C. The GPU only operates correctly with driver version 560.70; recent driver versions fail to maintain proper fan operation. The user also relies on the Palit ThunderMaster utility, which appears necessary for the GPU’s functionality. Without this utility, the GPU fails to operate correctly.

Troubleshooting Steps Undertaken

The user attempted several remedial actions, including:

Uninstalling the ThunderMaster utility
Using Display Driver Uninstaller (DDU) to thoroughly remove existing GPU drivers
Installing an older, stable driver version (560.70)

Despite these measures, the problem persisted, indicating that the issue is not straightforwardly resolved through conventional driver management.

Potential Causes and Analysis

Software Conflict or Driver Compatibility

The reliance on the ThunderMaster utility suggests that some proprietary software is integral to the GPU’s operation. Newer drivers may not be compatible with this utility or may disable hardware features it manages.
