Valve advised the owners of the Steam Deck portable game apps not to play in the open air at elevated air temperatures, and Europe and Britain in particular have been exposed to an abnormal heat this week, and the use of the device under such conditions may have an unpleasant effect.
The manufacturer specified that Steam Deck works most efficiently at an ambient temperature of 0 to 35 degrees Celsius. If the ambient temperature is higher than the specified maximum, the drive processor heats faster and the protective mechanism is activated to prevent overheating. The UK air temperature set a new historical record this week, passing 40 degrees Celsius, and in such conditions it is better not to use it.
Valve explains that the AMD Aerit processor of the four nuclear castes in Steam Deck is designed to operate at temperatures of up to 100 degrees Celsius. As soon as this figure exceeds the declared maximum, it drops the clock frequency of the chip, which has a negative impact on its productivity. In the worst case, if the temperature of the processor reaches 105 degrees Celsius, it is automatically switched off to avoid further overheating and damage to the integrity of its components.
It was not only Valve who warned about the risks of using electronics under inappropriate conditions. Previously, with similar recommendations, the Switch company, Nintendo, recommended the use of a cooler device. The Japanese manufacturer also noted that the maximum ambient temperature allowed for comfortable use was 35 degrees Celsius. The company also recommended that the Switch owners clean the console vents of dust and leave at least 10 cm of free space around them when using the drive.
