Bitaxe Basic Heatsink — No-Nonsense Cooling for Your Solo Miner
Not every Bitaxe needs a competition-grade cooling solution. The Bitaxe Basic Heatsink is a straightforward aluminum heatsink that keeps your miner running at safe temperatures at stock speeds and handles light overclocking without drama. It is affordable, functional, and gets the job done — exactly what you need if you are running your Bitaxe at stock settings or just pushing it a little past factory defaults.
Built for the 40 x 40 mm standard Bitaxe footprint and also compatible with the NerdAxe, this is the entry-level heatsink that every open-source miner should have.
Specifications
| Spec | Detail |
|---|---|
| Material | Aluminum alloy |
| Footprint | 40 x 40 mm (standard Bitaxe mount) |
| Cooling Type | Passive (pair with fan for active cooling) |
| Best For | Stock speeds and light overclocking |
| Installation | Direct mount with included hardware |
| Thermal Paste | Apply your own (thin layer recommended) |
What It Does
The Basic Heatsink pulls heat away from your ASIC chip through direct aluminum-to-die contact (with thermal paste) and dissipates it through its fin structure. It is designed for miners who want reliable cooling without overthinking it:
- Stock speed stability — keeps your Bitaxe within safe thermal limits during 24/7 operation
- Light overclock support — enough thermal headroom for modest frequency bumps
- Universal fit — standard 40mm mount works with all single-chip Bitaxe variants and NerdAxe
- Quiet potential — at stock speeds, a basic heatsink with a gentle fan keeps noise minimal
- Affordable — spend less on cooling, more on sats
Who Is This For
The Basic Heatsink is the right choice if you are:
- Running your Bitaxe at stock or near-stock settings
- Building a first-time solo mining setup and keeping costs down
- Setting up multiple Bitaxes and need affordable cooling across the fleet
- Using your miner as a desk ornament that hashes — low power, low noise, always running
If you plan to push past 900 MHz or want maximum overclocking headroom, check out the Premium Bitaxe Heatsink or the Bitaxe Modern Heatsink instead.

Frequently Asked Questions
Do I need a fan with the Basic Heatsink?
For stock speeds in a room-temperature environment, the heatsink alone may be sufficient with decent ambient airflow. However, we strongly recommend pairing it with at least a small 40mm fan for reliable 24/7 operation. ASICs generate serious heat, and passive cooling alone can be marginal in warm rooms or enclosed spaces.
What is the difference between the Basic, Premium, and Modern heatsinks?
The Basic is our entry-level option — solid aluminum, good for stock speeds and light overclocking. The Premium has a larger fin surface, includes a voltage regulator heatsink, and supports moderate overclocking. The Modern is engineered for extreme overclocking with advanced fin geometry and maximum thermal dissipation. Pick based on how hard you plan to push your miner.
Is thermal paste included?
Apply your own thermal paste for best results. A thin, even layer of any quality thermal compound (Arctic MX-4, Noctua NT-H1, etc.) will work. Do not over-apply — a rice-grain-sized amount spread evenly across the ASIC die is all you need.
Can I use this on a NerdAxe?
Yes. The Basic Heatsink uses the standard 40mm footprint that fits both Bitaxe single-chip boards and the NerdAxe. Note that the NerdAxe uses USB-C for power, not the 5V barrel jack used by Bitaxe models.
Why D-Central
D-Central is a pioneer in the Bitaxe ecosystem — we created the original Bitaxe Mesh Stand, developed the first dedicated Bitaxe heatsinks, and have been shipping open-source mining accessories since the beginning. The Basic Heatsink is our most affordable cooling option, but it is still built and tested by people who mine Bitcoin every day. No markup, no fluff — just functional hardware for solo miners. Every hash counts.
