A one-of-a-kind mod for the iPhone 17 Pro Max has caught the tech community's attention after showing surprisingly strong results in performance tests. A Reddit user named T-K-Tronix decided to stick several SSD heatsinks onto the back of the phone, and the benchmark results show a clear difference compared with a stock unit.
SSD heatsinks turn the iPhone into a "performance machine"
Plenty of cooling solutions already exist for mobile devices, but covering the back of an iPhone with SSD heatsinks is something few people would have thought of. The result looks rather odd, yet the 3DMark numbers surprised a lot of people. According to the post, the setup helps the iPhone 17 Pro Max hold steadier temperatures, which in turn improves performance during heavy tasks such as gaming or recording ProRes video.
In the 3DMark Steel Nomad Light Unlimited test, the iPhone with heatsinks recorded stability of up to 90.5%, with scores ranging from 2,455 to 2,712. By comparison, YouTuber Max Tech's results on a stock iPhone 17 Pro Max typically landed between 1,608 and 2,318, with stability of around 69.4%. Even though the standard model is already a big improvement over the iPhone 16 Pro Max, the difference the SSD heatsinks make is still very clear.
Temperature control and real-world use
Thermal images shared by T-K-Tronix show that the back of the iPhone where the heatsinks are attached stays below 25 degrees C, while uncovered areas such as the camera module climb past 35 degrees. This demonstrates how effective the cooling approach is, and it is especially useful for people who use their phones for demanding, sustained workloads.
Many commenters say Apple or accessory makers should consider building dedicated cooling kits for the iPhone, rather than leaving the modding community to come up with "Frankenstein" solutions like this one.
Not just about performance, but a new trend?
This is not the first time the iPhone 17 Pro Max has been heavily customized by users. Earlier, YouTuber DirectorFeng showed that storage could be upgraded from 256GB to 1TB by hand, saving a considerable amount of money. A mod that upgrades the phone to 2TB is also being tested, promising to kick off a new wave for those who want to get the most out of the iPhone's hardware.
Overall, the SSD heatsink mod for the iPhone 17 Pro Max shows the limitless creativity of the user community. Although it is not for everyone because of its awkward looks, the results it delivers are sure to get Apple thinking about offering professional cooling solutions for mobile devices in the future.
