Thermal Expansion Mod

Yes. Thermal Expansion is distributed free of charge by Team CoFH. If a site asks you to pay for it or to install a special downloader, close the page.

Minecraft Java Edition, Forge for your chosen Minecraft version, and the Thermal Expansion, Thermal Foundation and CoFH Core jars built for that same version. The install guide walks through each step.

We are not aware of an official Fabric release; the Thermal series is published for Forge. Tools that load Forge mods inside Fabric exist, but they are unsupported and often struggle with large tech mods.

No. Bedrock Edition cannot load Java mods. Add-ons with similar names are separate projects by other creators, not ports of Team CoFH's mod.

We could not confirm an official 1.17 build, so we do not list one. Check the mod's official file list filtered by game version, and be wary of unofficial sites offering one.

Classic versions such as 1.7.10 exist and appear in older modpacks. They need an old Forge build and Java 8, and they no longer receive updates, so a ready-made modpack is the easiest route.

The download button links to a GitHub archive of the 1.20.x branch of the CoFH/ThermalExpansion repository. That is source code for developers. To play straight away, use a compiled release jar instead.

In the mods folder inside your Minecraft directory, for example %appdata%\.minecraft\mods on Windows. Leave the jar zipped and place it directly in that folder, not in a subfolder.

Yes. Thermal Expansion adds blocks and items, so the server and every player must run the same Thermal files and versions, or players will be disconnected with a mod mismatch.

Usually yes, but back up the world first. New ores from the Thermal series generally appear only in chunks generated after installation, so you may need to explore new areas.

Thermal Foundation is the base mod of the Thermal series. It provides shared materials such as extra metals and alloys that Thermal Expansion's machines are built from and process.

Thermal Dynamics is an optional add-on that adds ducts for moving energy, items and fluids between blocks. Thermal Expansion works without it.

Redstone Flux, shown as RF, is the energy unit used by Thermal machines. Dynamos produce it and machines consume it. On modern Forge versions it works with many mods that use Forge's shared energy system.

Most players start with a Stirling Dynamo, which burns solid fuels such as coal or charcoal. Later dynamos use other fuels, such as lava in the Magmatic Dynamo.

Many players start with a Pulverizer for ore processing and a Redstone Furnace for powered smelting. Use a recipe viewer to see the exact recipes for your version.

The Pulverizer grinds ore into dust. Smelting that dust can yield more ingots than smelting the ore directly, and some recipes have a chance at a secondary byproduct.

It lets you set what each face of a machine does: accept input, give output, both, or nothing. That decides where ducts, hoppers and neighbouring machines connect.

Augments are upgrade items placed in a machine's augment slots to change its behaviour, such as speed or energy use. Available augments differ by version, so check tooltips in game.

Fan-made wiki pages exist, but many describe older versions. For accurate recipes, use a recipe viewer in your own game and check the mod's project page for current documentation links.

Often, because modern versions use Forge's shared energy system, so generators and cables from other mods can connect. How well a specific combination works depends on those mods.
