The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by running Furmark and Cinebench together. We included results from a diode which we placed beside the motherboard and the exhaust fan. Room ambient temperatures were 23c.
The Fusion products run very cool, and even in such a tiny, confined space, there are no problems even under extended load.
