In the ZMAX-AP, Iwill relies on fanless CPU cooling. The oversize copper block has three heatpipes. They are there to divert heat as quickly as possible to the copper fins. Two system fans directly behind the copper block take care of cooling the fins. In idle mode, the two fans purr away quietly. But when the CPU runs at capacity, the decibel level rises to 47 dB(a). During the boot process our indicator even reaches 55 decibels. But during our stress test we were not able to reach this peak. The heat levels in and on the device are in an acceptable range.
