Like all laptops and mobile PCs, there is some degree of power throttling (which is different from CPU thermal throttling) to keep the magnesium chassis of the Surface from getting too hot. Nonetheless, for a passively cooled system, Microsoft's Surface Pro with Core i5 does quite well. When running the fan at full speed with LED light turn on and set at full brightness we recommend running it from USB-C.

Those concerned that the fanless Surface Pro is underperforming to stay below thermal limits can be assured that not only is that not the case, but in fact the Pro is faster than the Surface Laptop with a Core i5 configuration.
