Heat Sink Size Calculator

The heat sink size calculator is based on a well-established equation for estimating heat sink volume during the early stages of heat sink design. A reference link has been placed below the calculator for further reading. In our experience, it generally estimates the overall heat sink volume within +/- 15% of a final design.

For assistance optimizing heat sink dimensions, materials, and fin attributes please contact us using the Request a Quote button at the top of this page. We welcome all inquiries involving heat sinks incorporating either heat pipes or vapor chambers. See “how to use” this calculator.

The next step is to determine heat sink performance and decide if a solid metal or vapor chamber base should be used to meet thermal targets. Please use our online Heat Sink Calculator for this step.
