ASUS X556U Fan Stuck at 100% After Drop… The Real Hidden Cause!

ASUS X556U full fan speed fix after drop damage! In today’s repair video, I’m working on an ASUS X556U that was dropped on the floor, causing two major issues: 1️⃣ The bottom screen assembly cover was cracked and partially detached 2️⃣ The laptop was powering on with the fan running at 100% full speed, even at idle After opening the laptop for a quick inspection, I discovered the real cause: 👉 One of the 4 PWM fan wires (PWM / feedback line) was cut by the internal frame during the fall. Because this ASUS uses a PWM-controlled fan, the fan was receiving full power but no control signal from the SIO chip, so it defaulted to full RPM. In this step-by-step repair I show you: 🔧 How to diagnose a fan stuck at maximum RPM 🔧 How to safely open and inspect the ASUS X556U internal frame 🔧 How I repaired the broken fan wire and restored proper fan control 💡 The laptop was fully repaired quickly — stable temperatures, silent fan operation, and the cover restored. Nice and fast repair! If you work on ASUS laptops or want to learn how to fix full-speed fan issues, you'll find this repair extremely helpful. #ASUSRepair #LaptopRepair #ASUSX556U #TechRepair #MotherboardRepair #ElectronicsRepair #PWMFanFix #FanFullSpeed
