  Answer: The fan is controlled via a switch: 1. Press the switch after connecting to start the fan. 2. Press it again to turn off the fan.
• Question 3: Why is my SSD's write speed much slower than its read speed on Windows?
  Answer: Enable write caching for improved performance:

1. Go to **Device Manager > Disk Drives > Select SSD > Properties > Policies** and enable write caching.

2. Under **Disk Management**, select the SSD, open **Properties > Strategy**, and enable "Better Performance" with write caching.

3. Ensure AHCI mode is enabled and the Intel RST driver is installed.
