SKU CH-KFX5-EPPK5

Set of 10 heat sinks for A4988 and A4983 stepper drivers

  • Cools A4988 drivers with dedicated heat sinks
  • Cools A4983 drivers with dedicated heat sinks
  • Ten-piece pack covers multiple stepper drivers
  • New condition ensures clean thermal contact

Compatible stepper-driver heatsinks

This pack contains ten low-profile heatsinks sized for A4988 and A4983 stepper-driver ICs. They press directly onto the driver package to draw heat away during extended print or CNC sessions. The set is intended for hobbyists and makers who run multiple boards and want spares on hand. No adhesive or mounting hardware is included.

Driver-model match decides fit

The only specification that matters is the driver model number printed on the chip. These heatsinks are cut for the A4988 and A4983 packages; other driver footprints will not align or make full contact. Verify the part number on your board before ordering.

Questions about this item

How much does the heatsink lower the temperature of an A4988 driver in a 3D printer?

The heatsink increases surface area on the A4988 chip so heat moves into the surrounding air faster, keeping the driver cooler during long prints.

Does the heatsink fit the A4983 driver the same way as the A4988?

Yes, the heatsink is sized for both the A4988 and A4983 stepper driver packages so it mounts on either one.
