As a hardware engineer at TinyChipHub, I get asked by miners every day: what exactly is the cooling module for the Bitaxe miner? Simply put, they are cooling accessories specifically designed for the Bitaxe series (like Ultra, Gamma, Hex, and Supra Hex), including a heatsink base, enhanced heatsinks, and high-performance thermal paste.
For example, our Enhanced Heatsink can directly lower the miner's core temperature by over 5°C, preventing thermal throttling. Don't underestimate these small parts; They enable your miner to run at full hashrate and extend its lifespan by at least 10%! Let me break it down for you in detail.
(📢Preview：TinyChipHub will equip new products with more advanced water cooling accessories in the future, keeping up with the new era)
What's Cooling❓
Cooling is essentially the process of helping the miner "reduce its fever" 🤒️ → 🤧 → 😊: it carries away the heat generated by the chip to prevent it from burning out.
When the miner operates, the SHA-256 algorithm causes the ASIC chip to run under continuous high load, and the temperature can skyrocket to over 55°C in seconds. At this point, the cooling module acts like an air conditioner for the chip. The core principle relies on heat conduction and convection to dissipate the heat into the air.
Taking the Bitaxe Ultra as an example, our 2024 tests found that without a cooling module, the chip junction temperature could hit 60°C. But after adding the Enhanced Heatsink, it immediately dropped below 55°C!
-
Authoritative Endorsement: The IEEE 1156-2021 standard requires miner cooling to ensure a chip junction temperature of ≤65°C. Our modules are all certified with CE safety and other certifications.
-
Risk Warning: Don't cheap out and use no-name heatsinks! I've seen people use counterfeit parts with a thermal resistance as high as 0.5°C/W, resulting in chip desoldering within six months; the repair cost was higher than the machine itself.
| Cooling Method | Applicable Miner | Max Cooling Power | Noise Level |
|---|---|---|---|
| Passive Heatsink | Bitaxe Ultra (500 GH/s) | 11W | 38 dB |
| Active Fan Cooling | Bitaxe Hex (3 TH/s) | 57W | 42 dB |
Regarding installation, pay attention to this detail: apply thermal paste between the heatsink and the chip to fill gaps.
Now! 🔥➡️❄️Stop Overheating
To identify and prevent overheating, you need to watch for several key signals.
-
Hashrate Fluctuation：The temperature sensor built into the chip automatically triggers the "Thermal Throttling" mechanism to protect itself by reducing frequency once it detects a temperature spike.
-
Listen for sound: The fan speed screams, and the noise increases significantly. This is an alarm that the cooling system is "struggling."
-
Display screen warning: When the temperature exceeds 70 degrees Celsius, the screen will issue a high temperature warning and stop working, while the fan will continue to dissipate heat;
-
Check the logs: High-temperature alarm logs appear in the management backend, which must be addressed immediately.
The most direct risk is solder joint fatigue. repeated thermal expansion and contraction can cause the solder joints between the chip and the PCB to crack, causing permanent damage. Therefore, providing the miner with a well-ventilated environment and regularly dusting it are the most cost-effective maintenance practices.
Cooling Module Types ⭐
Bitaxe's cooling solutions are mainly divided into three categories: passive cooling, active air cooling, and hybrid cooling. Choosing which one 🤔 depends on your miner model and usage scenario.
The most basic is passive cooling, which relies entirely on natural convection between the heatsink and the air. Its effectiveness core is the "surface area fin ratio" of the heatsink.
For performance beasts like the Bitaxe Supra Hex, active air cooling is standard. Its principle uses fans to forcibly blow heat away from the heatsink. The core metrics are "air pressure (Pa)" and "airflow (CFM)".
Our Enhanced Bitaxe Stand Cooling Kit is an integrated solution that includes a high-performance turbo fan, providing 2.5 CFM of airflow and lowering the core temperature by another 5-6℃. It has IP5X dust resistance certification, effectively extending the fan's life in harsh environments.
| Cooling Type | Core Principle | Applicable Models | Cooling Capacity (ΔT vs ambient) |
|---|---|---|---|
| Passive Cooling | Natural Convection | Bitaxe Ultra, Bitaxe Gamma (low load) | 0℃ |
| Active Air Cooling | Forced Convection | Bitaxe Hex, Bitaxe Supra Hex | 5-6℃ |
| Hybrid Cooling(Passive + Active) | Natural + Fan Assist | All models, for extreme overclocking | 5-10℃ |
According to assessments by the Electronic Industries Association (EIA), active cooling significantly improves equipment reliability in high-temperature environments.It is recommended to check the fan status every 10,000 hours of operation to avoid a single point of failure causing the entire machine to overheat.
Max Power💪, Min Stress!🏃
Want to squeeze out every bit of hashrate from your solo miner but worry about overworking it? Optimizing cooling is key. The most crucial first step is improving the performance of the Thermal Interface Material (TIM).
TinyChipHub's independent lab tests showed that using High-Performance Thermal Paste for Miners compared to ordinary paste can lower the chip temperature by another 3-5℃. When applying it, remember to use a silicone scraper for smooth scraping.(Buy Thermal Paste for Miner and get a free scraper)
-
Optimize Airflow: Keeping it at least 20 centimeters away from walls to avoid hot air recirculation.
-
Environment Cooling: For every 1℃ drop in ambient temperature, the chip temperature roughly decreases accordingly.
At the 2024 International Microelectronics Assembly and Packaging Society (IMAPS) conference, research indicated that optimizing TIM and heatsink contact pressure could reduce interfacial thermal resistance by over 15%.
