Review of Phones With the Best Thermal Cooling Systems

In the fast-evolving world of smartphones, performance is key, but so is managing heat. Phones with the best thermal cooling systems ensure sustained performance, prevent overheating, and enhance user experience during gaming, multitasking, or heavy app usage. In this review, we dive into the top smartphones of 2025 renowned for their advanced cooling technologies, exploring their features, benefits, and why they stand out.

Why Thermal Cooling Matters in Smartphones

Modern smartphones pack powerful processors that generate significant heat during intensive tasks like gaming, video editing, or 5G connectivity. Without efficient cooling, devices can throttle performance, reduce battery life, or even shut down to prevent damage. Advanced cooling systems, such as vapor chambers, graphite layers, and liquid cooling, dissipate heat effectively, ensuring consistent performance and comfort during prolonged use.

In this article, we’ll review the best phones with cutting-edge thermal management, ideal for power users, gamers, and anyone seeking a reliable device.

Top Phones With the Best Thermal Cooling Systems in 2025

1. ASUS ROG Phone 9 Pro

The ASUS ROG Phone 9 Pro is a gaming beast, and its cooling system is a major reason why. It features the AeroActive Cooler X, an external cooling accessory that enhances airflow, paired with an internal vapor chamber and graphite sheets. This dual approach ensures the Snapdragon 8 Gen 4 processor stays cool even during marathon gaming sessions.

• Cooling Features: Large vapor chamber, AeroActive Cooler X with thermoelectric cooling, and multi-layer graphite.
• Performance Benefits: Sustained high frame rates in games like Genshin Impact and Call of Duty Mobile without thermal throttling.
• Why It Stands Out: The external cooler adds versatility, making it ideal for hardcore gamers.
• Price Range: Approx. $999–$1,200.

2. Samsung Galaxy S25 Ultra

Samsung’s flagship Galaxy S25 Ultra incorporates an advanced liquid cooling system combined with a vapor chamber that’s 20% larger than its predecessor. This setup efficiently manages heat from the Exynos 2500 (or Snapdragon 8 Gen 4 in some regions), making it perfect for multitasking and 8K video recording.

• Cooling Features: Enlarged vapor chamber, liquid cooling, and thermal interface materials (TIM) for better heat transfer.
• Performance Benefits: Stays cool during prolonged 8K video recording and heavy multitasking.
• Why It Stands Out: Balances premium design with robust cooling for all-day performance.
• Price Range: Approx. $1,299–$1,499.

3. RedMagic 10 Pro

The RedMagic 10 Pro is another gaming-focused phone with an impressive multi-dimensional cooling system. It combines a vapor chamber, turbo fan, and graphene layers to keep temperatures in check. The built-in fan actively dissipates heat, a rare feature in smartphones.

• Cooling Features: 10,000 RPM turbo fan, large vapor chamber, and graphene heat dissipation layers.
• Performance Benefits: Exceptional thermal management during extended gaming, with temperatures rarely exceeding 40°C.
• Why It Stands Out: The active fan cooling sets it apart for gamers who prioritize low temperatures.
• Price Range: Approx. $799–$999.

4. OnePlus 13

The OnePlus 13 introduces a dual cryogenic cooling system, featuring a vapor chamber and liquid cooling pipes. This setup ensures the MediaTek Dimensity 9400 processor remains cool, even under heavy workloads like 4K video editing or AR applications.

• Cooling Features: Dual-layer vapor chamber and liquid cooling pipes with high thermal conductivity.
• Performance Benefits: Minimal performance drop during intensive tasks, with excellent heat dissipation.
• Why It Stands Out: Offers flagship-level cooling at a competitive price point.
• Price Range: Approx. $899–$1,099.

5. iPhone 16 Pro Max

Apple’s iPhone 16 Pro Max uses a graphite thermal module and metal frame dissipation to manage heat from the A18 Pro chip. While not as aggressive as gaming phones, its passive cooling system is highly efficient for everyday tasks and light gaming.

• Cooling Features: Graphite sheets and optimized metal frame for passive heat dissipation.
• Performance Benefits: Maintains consistent performance during video streaming and photo editing.
• Why It Stands Out: Sleek design with reliable cooling for non-gaming users.
• Price Range: Approx. $1,199–$1,399.

What to Look for in a Phone’s Cooling System

When choosing a phone with a top-tier cooling system, consider these factors:

• Cooling Technology: Look for vapor chambers, liquid cooling, or active cooling (fans) for maximum heat dissipation.
• Processor Efficiency: Pairing a cooling system with an efficient chip (e.g., Snapdragon 8 Gen 4 or A18 Pro) enhances performance.
• Use Case: Gamers may prefer active cooling (like the RedMagic’s fan), while casual users can opt for passive systems (like the iPhone’s graphite layers).
• Build Quality: Metal or glass backs can aid heat dissipation but may feel warmer to the touch.

Benefits of Advanced Thermal Cooling

• Improved Performance: Prevents thermal throttling, ensuring smooth operation during demanding tasks.
• Longer Device Lifespan: Reduces wear on components caused by excessive heat.
• Better User Experience: Keeps the phone comfortable to hold during extended use.
• Enhanced Battery Health: Lower temperatures help maintain battery efficiency over time.

Choosing a smartphone with an excellent thermal cooling system is crucial for users who demand high performance without compromise. The ASUS ROG Phone 9 Pro and RedMagic 10 Pro lead for gamers with their active cooling solutions, while the Samsung Galaxy S25 Ultra and OnePlus 13 offer versatile cooling for all-around use. For Apple fans, the iPhone 16 Pro Max delivers reliable passive cooling in a sleek package.
