Yeah, swapping the stock fan for a Noctua definitely helps. But if noise is a real problem, you can go further. You’ve got an NH-D15 lying around — perfect! Print a mount, slap it on the chip, and you’ll drop temps a lot with almost zero noise.

Also, underclocking helps more than people think. Try 550MHz at 1100mV — runs cooler, quieter, and still mines fine.

If you wanna go full DIY, build a wooden box lined with foam or old towels. Add a couple of big slow-spinning fans (like 140mm Noctuas or Arctic) for airflow. Super quiet and cheap.

I’ve seen people even use old PC water cooling — works like magic if you’ve got parts lying around.

Bottom line: Big fans, underclock, and some DIY airflow tricks = silent Bitaxe.
