[* black] The Surface Pro 4's heatsink has undergone an impressive makeover, flaunting longer copper heat pipes and a large copper plate for added heat dissipation.
- [* icon_note] Most likely, this was done to address heat related throttling issues by allowing heat to collect and dissipate away from the CPU.

[* black] Designed with a hybrid cooling system, the Pro 4 takes advantage of both passive and active cooling.
- [* black] More powerful models have a fan that activates when temperatures get too high for passive cooling.
+ [* icon_note] Well, ''some of them'' do. Our unit apparently uses a combination of passive cooling and...well, passive cooling. More powerful models include a fan that activates when temperatures get too high for passive cooling.
[* black] Once extracted from its home, this heatsink is a strange sight to behold.
