![](../img/kasli_fan.jpg)
1. ⚠️ Verify the fan has the **correct polarity (powering on with wrong polarity will burn the MOSFET in series💥)**
2. Place the fan on a heatsink
3. Tap 3 threads on the heatsink using M2.5 pointy tapping screws (e.g. front panel screws)
4. Replace the tapping screws with M2.5x14mm screws
5. Verify the fan is secure
