Mining any type of crypto-currency is highly intensive in terms of CPU activity and requires ever increasing levels of computing power. This increased power consumption requires more electricity and this leads to much higher levels of heat generation. All this energy consumption equates to the costs of successfully mining crypto currency easily becoming prohibitive.
As the CPU temperatures rise the power consumption of mining machine ASIC drastically increases, therefore real time temperature monitoring systems are necessary to allow for power optimization. In-chip embedded temperature sensors help extend device lifetimes and provide protection through the enablement of shutdown schemes, the latter being as a result of rising temperatures from sudden increases in dynamic CPU load profiles.
These new mining products however are able deal with the increased level of heat by employing such embedded temperature sensors in areas with known hotspots on the die. A miner generally consists of an ASIC chip, power source, fan, and mining software. These machines are typically used in multiples in a rack layout.
Although thermal issues are a big problem for crypto mining ASICs, and embedded temperature sensors can go a long way to address this, we can also look at methods of increasing general device reliability and enhanced performance optimization within the chip itself. With high levels of processors, memory, disk and operating systems high performance computers suffer from issues related to power consumption and temperature which subsequently affects their performance. By employing embedded in-chip monitors for not only temperature but also process and voltage, crypto-currency integrated circuit designers can address these challenges and optimise the performance of the design.
