We Cooled a Computer with FIRE - Hacksmith Collab

This collaboration pulls off one of Hacksmith’s most audacious cooling experiments by attempting to subzero cool a high end PC using propane flames. The setup starts with a simple, apparent two-part system: a liquid propane feed that cools the electronics in an inline expander, and then a flame expander that creates visible heat while the propane gas helps pull heat away from the CPU. The team demonstrates a baseline test with a standard cooling configuration, then progressively ramps up to more aggressive cooling arrangements, including external voltage control and multi-radiator mounting. They also introduce safety measures such as a fire extinguisher and deliberate checks to avoid direct liquid propane contact with critical components. The narration and on-screen teamwork emphasize practical engineering tradeoffs, like condensation management, dielectric protection, and bracket design to fit heavy cooling hardware onto a consumer motherboard. Overall, the episode blends high entertainment value with genuine engineering experimentation as the crew pushes beyond conventional cooling methods while tracking performance with Cinebench scores and thermal behavior. The video underscores that while flames can boost heat transfer, there are significant safety and reliability concerns that limit practical usage in everyday PCs, even as spectators enjoy the spectacle and the learning opportunity from the process.
