The iPhone 17 Pro and iPhone 17 Pro Max mark Apple’s initial foray into devices featuring vapor chambers, a technology that Android smartphone manufacturers have utilized long before Apple, aimed at cooling more powerful processors. Paired with the unibody aluminum design that flows towards the rear, covering the camera plateau and smoothly transitioning along the side and bottom edges, the vapor chamber is anticipated to transfer heat away from the robust A19 Pro chip more effectively than the previous cooling systems utilized in earlier iPhone versions. Reviews of the iPhone 17 have indicated that the cooling mechanism is effective, preventing overheating and enabling the iPhone 17 Pro models to sustain optimal performance longer than iPhone models lacking vapor chambers and an aluminum structure.
However, one Reddit user sought to determine if they could enhance the cooling of the iPhone 17 Pro Max beyond what the device provides out of the box. T-K-Tronix affixed multiple M.2 SSD heatsinks on the rear of the iPhone, as shown in one of the following images. The resulting setup managed to achieve even better performance in demanding benchmarks, without experiencing a drop in performance as swiftly as the standard iPhone 17 Pro Max. The phone maintained over 90% stability over 20 runs of the 3D Mark Stress Test:
The iPhone 17 Pro Max modification that the Reddit user constructed demonstrated that the device can become an even more dependable tool for resource-heavy tasks, provided that the cooling is sufficient.
Attaching heatsinks to the back of the iPhone 17 Pro and iPhone 17 Pro Max to mitigate throttling is not a feasible solution. Reviews have indicated that Apple’s vapor chamber does indeed keep the new Pro variants cooler than the iPhone 17, iPhone Air, and earlier-generation models. Whether you’re employing the iPhone 17 Pro models for professional purposes or as an everyday consumer, heat dissipation should not be a concern. The i
