HP Envy 15 ep2 — GPU Fan Always Running Fix
Switch to Balanced Power Plan Most common
Right-click the battery icon → Power and sleep settings → Power mode. Change from Best Performance to Balanced. This stops the CPU from running at full speed at idle, reducing heat and fan noise immediately.
Update Intel Thermal Framework Driver
Download the Intel Dynamic Tuning Technology driver from HP Support for Envy 15 ep2. This driver controls how aggressively the fans respond to temperature changes.
Use HP Command Center
Install HP Command Center from the Microsoft Store. Set the performance mode to Quiet or Balanced. This directly controls the fan curve via HP firmware.
“Switching to Balanced power plan on my HP Envy 15 ep2 stopped the constant fan noise within seconds.” — Devi, Petaling Jaya
Common questions
Why do fans spin at startup?
Normal — fans run briefly while the CPU warms up. Continuous spinning at idle indicates a power plan or driver issue.
Is it safe to use the Quiet mode?
Yes for everyday tasks. Avoid Quiet mode during heavy workloads as it limits cooling and can cause thermal throttling.
Can dust cause constant fan noise?
Yes. Dust blocks the heatsink fins and forces fans to spin harder. Cleaning the vents with compressed air every 6 months prevents this.
Does undervolting help reduce fan noise?
Intel Core i9 12900H undervolting is locked in BIOS on most HP systems. Use the power plan and HP Command Center instead.
