The Bitaxe V-Rex heatsink is a tiny rear-mounted VREG heatsink with a very important job: taming the notorious VREG (voltage regulator) hotspot on the Bitaxe Gamma 602. CNC-machined from custom-extruded aluminium, it bolts to the back of the board and pulls heat straight out of the regulator so your Bitaxe can run harder and stay happier. V-Rex is designed to work alongside your front heatsink and fan. The rear, through-hole design gives you a solid mechanical connection and reliable contact where it matters most, without relying on sketchy stick-on heatsinks that fall off as soon as things get warm. Pair it with other Bitaxe upgrades The V-Rex really comes into its own when you’re pushing your Bitaxe Gamma harder with bigger front heatsinks, higher fan speeds or more aggressive overclocking. For a complete setup, pair the V-Rex heatsink with other accessories from the Bitaxe accessories range – such as upgraded stands, fans and power supplies – to build a stable, tidy home mining rig that can take the heat. Features * Purpose-built VREG cooler for the Bitaxe Gamma voltage regulator * CNC-machined aluminium from custom-extruded stock for a precise fit * Rear-mounted, through-hole design – works with front heatsinks and fan setups * Includes 1 mm thermal pad – sized for the VREG (peel both sides before install) * OSMU & GekkoScience compatible – tested on both board variants * Designed by I Am GPIO specifically for home Bitaxe builds Community Review As PlebBase put it in their independent, no-BS review: "The small miracle cooler is an absolute MUST HAVE for everyone, really! No more hassle with coolers falling off, perfect connection and workmanship.” Resources Installation Fitting the V-Rex is straightforward, and once fitted, becomes part of a solid front-and-rear cooling stack, helping stabilise the regulator when overclocking or running higher ambient temperatures: * Power down and unplug your Bitaxe Gamma * Apply the supplied 1 mm thermal pad to the VREG on the rear of the board (peel the plastic from both sides) * Align the V-Rex heatsink over the VREG and board holes * Bolt it through using your chosen front heatsink / mounting hardware * Power up the Bitaxe and monitor VREG temperature in AxeOS or your preferred stats view Package Contents * 1x V-Rex VREG Rear Heatsink for Bitaxe Gamma * 2x Thermal pads Bitaxe Gamma not included
