TC_AccelSynchron is a small standalone addon for Minecraft 1.20.1 (Forge) that adds tuneable Overclock Heater blocks for Tinkers' Construct Smelteries and Foundries.
Place the heater directly on top of a Smeltery or Foundry controller to speed up melting. Right-click to cycle through 1x / 2x / 4x / 8x / 16x speed; sneak + right-click cycles backward. 1x turns acceleration off.
