Common NerdQaxe++ Errors and What They Mean
Your NerdQaxe++ might give you headaches if it's not working right. You can save hours of debugging time by learning to spot common error patterns in these compact miners.
PSU error #0000015 explained
The PSU error #0000015 shows up as a "Guru Meditation" message on your display screen. This error happens because of a gap between the chip and heatsink. Moving your miner around can make the heatsink slip a bit and break the thermal contact. The power supply unit can't regulate voltage properly and shuts down to protect itself.
Overheating and thermal shutdowns
NerdQaxe++ miners keep track of both ASIC and VREG temperatures. The VREG temperature matters most for BM1370 ASIC processors. Your miner will slow down or shut off completely if these parts get too hot. Users report temperature drops from 60°C+ to 48.4°C just by adding external cooling. These thermal shutdowns happen more often in rooms that run hot.
Wi-Fi and network connection failures
A "No AP Found" message usually means you've got the wrong WiFi credentials. Your miner might connect but show high rejection rates because of unstable network or ISP issues. The NerdQaxe++ works best with 2.4GHz networks. Users found their connection problems went away after setting up a network that only uses 2.4GHz.
Display not showing hashrate
A display showing "0 H/s" while connected to WiFi and a mining pool points to power or thermal problems. Your miner connects but can't start the mining process. This often comes with PSU errors in the logs. You'll need to check your firmware version and power supply.
Fan noise or failure symptoms
Strange fan noises or complete fan failures warn you about upcoming problems. The built-in cooling system doesn't handle heat well in spaces with poor airflow. A good fan should run at steady speeds based on temperature. Fan problems can trigger the automatic control system and cause fuse issues in NerdQaxe+ and NerdQaxe++ models.
Diagnosing the Root Cause
The true cause of your NerdQaxe++ problems needs methodical testing instead of random fixes. A systematic diagnostic approach will help you pinpoint the exact cause of your mining troubles.
Check for loose heatsink or thermal gap
Power off your miner completely before inspection. The heatsink needs careful removal to check the thermal paste condition. PSU error #0000015 happens because shipping vibrations create gaps between the ASIC chip and heatsink. A minor separation can make temperature sensors misread and trigger automatic shutdowns. Dried, cracked, or uneven thermal paste application causes most overheating issues. Many users find that reseating the heatsink fixes their problems completely.
Inspect pin alignment and slot connection
The heatsink inspection should lead to checking all pins and connections. Misaligned pins create a 3.3V short circuit that causes erratic behavior or complete failure. Connection points need inspection for overheating or burning signs. Pins must sit firmly in their slots without wobbling. Slightly bent pins cause intermittent issues that become hard to diagnose. Quality connections directly affect power delivery to critical components.
Monitor temperature and voltage readings
Your miner's operating system shows immediate temperature data through its IP address. The NerdQaxe++ tracks both ASIC and VREG temperatures - VREG readings matter more for BM1370 ASIC processors. Firmware version 1.0.29's new PID feature lets you set target temperatures and adjusts fan speeds automatically. The best operation keeps ASIC temperatures around 60-62°C. Readings above 70°C point to cooling problems or thermal paste issues.
Use the display to identify error codes
The onboard display shows important diagnostic information beyond hashrate. Error codes flash briefly before shutdowns happen. A zero hashrate display (0.0 GH/s) with WiFi connection usually means power delivery problems, not network issues. "Overheat Mode" appears on the display at temperatures above 75°C. The device's AxeOS interface provides detailed logs and temperature graphs through the IP address shown on the display.
How to Fix NerdQaxe++ Errors Step-by-Step
Let's take a closer look at fixing these common NerdQaxe++ problems with practical solutions that will restore your miner's optimal performance.
Fixing PSU error #0000015 with thermal paste reapplication
A gap between the chip and heatsink causes the PSU error #0000015. Here's how to fix it:
-
Power down and disconnect your miner
-
Remove the heatsink screws carefully
-
Clean off old paste with isopropyl alcohol (90%+)
-
Apply a pea-sized amount of high-quality thermal paste (6W+ like Arctic MX-4)
-
Reattach the heatsink with even pressure
Reinserting misaligned pins to avoid 3.3V short
Dangerous shorts can happen from misaligned pins. The solution is straightforward - squeeze the connector pins and check they sit properly. Your mounting brackets should be right-side up after transport to prevent gaps between heatsink and chip.
Resetting network settings for Wi-Fi issues
Double-check your credentials when you see "No AP Found" messages. The AxeOS dashboard needs a complete network settings reset. Network instability shows up as high rejection rates - a dedicated 2.4GHz network could give you better stability.
Cleaning dust and improving airflow
Your miner needs monthly dust removal to prevent overheating:
-
Use compressed air in short bursts
-
Hold fan blades still to prevent overspinning
-
Gently wipe surfaces with lint-free cloth
Updating firmware to resolve software bugs

Preventing Future Issues with Smart Setup
Proper maintenance routines help prevent NerdQaxe++ problems. These preventive steps can help you avoid frustrating PSU errors and performance problems.
Use Arctic MX-4 or similar 6W+ thermal paste
Quality thermal paste substantially affects ASIC temperature. Arctic MX-4 or MX-6 are recommended options for NerdQaxe++ miners. The thermal paste degrades with time, so you should replace it every 6-12 months. A thin layer works best since too much paste actually insulates rather than conducts heat.
Place miner in a cool, ventilated area
The device's placement can affect its lifespan substantially. Your device needs an open space with good airflow. When ambient temperatures rise, cooling systems work harder and components wear out faster. Keep your miner away from cramped, enclosed spaces that trap heat.
Secure heatsink screws after transport
Shipping vibrations often create gaps between chips and heatsinks. You should check and tighten all mounting hardware after receiving or moving your miner. The heatsink needs a gentle back and forth movement to ensure it sits properly.
Avoid overclocking without proper cooling
Overclocking can boost performance to 5.5TH/s (15% increase), but you should be careful. Test your stock settings for 1-2 hours before making any adjustments. Your hardware's lifespan shortens with excessive overclocking.
Regularly monitor hashrate and temperature
Early problem detection requires consistent monitoring. Watch temperature patterns—your miner works best when ASIC temperatures stay around 48-50°C. You should check for maintenance when unusual fluctuations occur.
