Too Hot to Handle is a secret achievement/trophy in the System Rift expansion for Deus Ex: Mankind Divided. It is awarded for successfully navigating the Palisade Blade's server chambers without being fully detected by any heat sensing drone, camera or turret.
After riding the funicular up to the server chamber's level, the player will have to navigate past two large rooms full of security devices to reach the NSN interface chamber. There are no human enemies in this area, though the security bots, cameras and turrets are upgraded with HeatEye sensors which enables them to detect the heat signatures of any would-be intruder.
In short, these devices can see right through one's Glass-Shield Cloaking System, rendering it moot for the entire duration of the segment, forcing the player to make extensive use of covers as they maneuver around their sight lines.
The Remote Hack augmentation can be of great use here if the player is precise with their timing as it'll allow them to temporarily disable any device they see, or raising obstructions to limit said devices' field of view. Otherwise, an adequately-upgraded Hacking: Capture augmentation with Bot and Turret Domination can be used to breach the two security terminals in thek second area and permanently disabling most of the patrol bots and turrets in the vicinity.
If they haven't caught the full attention of any security device on their way, the achievement will pop once the player reaches the room with the NSN chair.
