AXP60 Copperzilla Kupfer Kühler 3.0

The AXP60 Copperzilla 3.0 is the heatsink for everyone whose Gamma board leaves too little room above the temperature limit with its stock cooling. On the ASIC sit 210 g of solid copper, two heatpipes pull the heat out of the contact surface into the fin stack, and a 60 mm fan pushes it out.

Copper takes up heat faster than aluminium and buffers load peaks instead of passing them straight to the temperature readout. The board runs more evenly, and you have room to raise frequency and voltage.

• Mass instead of fan speed: 210 g of copper absorb heat before the fan has to spin up at all.
• Two heatpipes: they pull the heat out of the small contact area and put the whole fin stack to use.
• 60 mm instead of 40 mm: the larger fan moves the same volume of air at a lower speed.
• Headroom for sustained load: if you mine around the clock, you work with distance from the temperature limit instead of right at it.

The AXP60 Copperzilla fits both Gamma boards: the Bitaxe Gamma and the Nerdaxe Gamma. It is not intended for:

• older Bitaxe models with a different layout and mounting pattern
• the larger boards of the NerdQaxe and NerdOctaxe series

Take the old heatsink off, clean the contact surface, seat the Copperzilla, plug in the 60 mm fan. Nothing is soldered or drilled. Customer feedback does show that one spot is fiddly during alignment – take a few quiet minutes for it. How the miner starts up again afterwards is covered in the Bitaxe setup guide and the Nerdaxe Gamma setup guide.

For everyone who does not run their Gamma at factory settings but adjusts frequency and voltage – and for anyone who wants permanent headroom in a warm room.

It is less of a fit if your miner should stay compact and discreet on a desk: the Copperzilla is considerably larger than the stock cooling. If that is too much, an adjusted fan curve is often enough on its own.

Delivered are the heatsink, the 60 mm fan and, depending on the set variant, the mounting hardware. Thermal paste is not listed as a separate item – have some ready if you are out. Beyond that you only need a spot with some airflow.

• Copper heatsinks for the voltage regulators – the Copperzilla cools the ASIC, not the rest of the board.
• ICE Tower Low Profile kit if you would rather fit a complete set with bracket, paste and Y-splitter.

If your Gamma board works at the temperature limit or you need room above it when overclocking, the AXP60 Copperzilla is the most direct answer: more copper, more surface, more airflow.
