Expanding Minecraft Thermally! A server-friendly and content-rich blend of magic and technology!
For nearly a decade, the Thermal Series mods have been a cornerstone of modded gameplay. They've pioneered gameplay innovations and optimizations used in practically every modern mod in existence. The Forge Energy system was built from Redstone Flux, and many common modded features - side reconfiguration, advanced redstone control, blue/orange input coloring - all started with the Thermal Series.
The Thermal Series is a modular series of mods, allowing players, server owners, and modpack creators to easily choose the aspects which they want and those which they do not, allowing it to fit into a variety of gameplay styles and worlds.
As a set, the mods form a cohesive experience which greatly expands the Minecraft universe in a lore-friendly (but admittedly technological) way.
This module contains "Expansion" - the original mod in the series, going all the way back to Minecraft 1.2.5. It contains the "industrial base" of the Series, providing options for energy generation, storage, and resource processing!
The mods are still being updated regularly and the Series is not complete yet! We're working on it and appreciate your patience. Even so, there's a LOT of stuff for both newcomers and veterans. We hope you enjoy the new Thermal Series.

Whether you are a veteran builder constructing massive cities, or simply a casual player looking to upgrade your survival world, this guide will provide you with all the essential details on how Thermal Expansion alters the game.
What Makes It Special?
Unlike standard mods that simply alter superficial elements, Thermal Expansion introduces a wide array of visual and mechanical features designed to seamlessly blend into the vanilla aesthetic. TeamCoFH has clearly spent significant time refining the project to ensure that every aspect feels polished and responsive for version 1.20.1.
Installation Guide
Getting Thermal Expansion up and running is straightforward. Follow these step-by-step instructions:
- Verify Your Version: Ensure your Minecraft launcher is set to version 1.20.1.
- Install Mod Loader (if required): If this is a mod, download the compatible loader (Forge, Fabric, NeoForge).
- Download the File: Click the secure download button above to retrieve the official file from CurseForge.
- Move the File: Place the downloaded file into your `mods`, `shaderpacks`, or `resourcepacks` folder depending on the mod type.

Compatibility & Performance
Compatibility is robust. Thermal Expansion is designed specifically for version 1.20.1, taking full advantage of the latest engine optimizations. During typical gameplay, this addition maintains a stable frame rate, though lower-end laptops might experience slight stuttering. We recommend pairing this with performance boosters like Sodium or Iris to guarantee a silky-smooth experience.
