Dual CPU Cooler Mod Pushes Snapdragon 8 Elite to Near-Perfect Benchmark Stability
A wild smartphone cooling experiment has shown just how much performance can be unlocked when thermal limits are pushed far beyond normal mobile design. A ZTE Nubia Z70 Ultra equipped with the previous-generation Snapdragon 8 Elite chipset and 24GB of RAM was modified with not one, but two desktop-class CPU coolers attached to the phone.
The result was extreme, impractical, and surprisingly effective.
The unusual setup was created to reduce thermal throttling during demanding GPU benchmark tests. Modern flagship smartphone chips are incredibly powerful, but sustained performance often drops when heat builds up. This is especially noticeable in stress tests such as 3DMark Wild Life Extreme and Solar Bay Extreme, which are designed to push mobile hardware for long periods.
With the dual-cooler setup installed on both the front and back of the device, the Snapdragon 8 Elite delivered almost perfect performance stability. In the 3DMark Wild Life Extreme Stress Test, the chip achieved 99 percent stability. In the Solar Bay Extreme Stress Test, it reached an even higher 99.2 percent stability.
Those numbers are impressive because even the best flagship phones usually struggle to maintain peak performance under prolonged load. Smartphone cooling systems are limited by slim designs, sealed bodies, and battery safety requirements. By using oversized external coolers normally intended for desktop processors, this experiment removed much of that thermal restriction.
The benchmark results were strong enough for the older Snapdragon 8 Elite to match or outperform newer flagship mobile chipsets in certain tests, including the Snapdragon 8 Elite Gen 5, Apple A19 Pro, and MediaTek Dimensity 9500. That does not mean the older chip is generally faster in everyday use, but it does show how much thermal headroom can affect benchmark performance.
In 3DMark Solar Bay Extreme, the modified ZTE Nubia Z70 Ultra recorded a best loop score of 1,083 and a lowest loop score of 1,074. That small gap between the highest and lowest scores highlights how stable the device remained throughout the stress test.
The Wild Life Extreme Stress Test showed similar consistency. The Snapdragon 8 Elite reached a best loop score of 6,641, while the lowest loop score was 6,575. Again, the tiny drop proves that the aggressive cooling solution nearly eliminated performance throttling.
This kind of modification is clearly not practical for daily smartphone use. Attaching two large CPU coolers to a phone makes it bulky, awkward, and far from portable. However, for enthusiasts chasing benchmark records, it offers an interesting alternative to even more extreme methods such as liquid nitrogen cooling.
A similar cooling-focused experiment was previously performed on the iPhone 17 Pro Max, where several large SSD heatsink-style coolers were attached to the back of the phone. That device reportedly reached 90 percent stability in 3DMark Steel Nomad Light, showing once again that external cooling can dramatically improve sustained mobile performance.
The biggest takeaway is simple: flagship smartphone chips are often limited less by raw silicon performance and more by heat. When cooling is improved dramatically, even a previous-generation Snapdragon processor can perform at a level that challenges the latest mobile chipsets.
For mobile gaming, emulation, and benchmark enthusiasts, this experiment is a reminder that thermal management remains one of the most important factors in real-world performance. The Snapdragon 8 Elite may no longer be the newest flagship chip, but under extreme cooling, it still has enough power to surprise newer rivals.
