Is RTX 5090 Overheating? Testing GameMax Liquid Coolers with 20℃ Temperature Drop

RTX 5090's Cooling Dilemma: The Battle Between High Performance and Excessive Heat

With the release of the RTX 5090 graphics card, its new AD102 core and power design exceeding 450W TDP have posed severe cooling challenges. Test data shows that the core temperature often breaks 105℃ under 4K ray-tracing full load, with memory temperatures exceeding 95℃, even triggering thermal throttling. Traditional air cooling proves insufficient under high loads, making all-in-one (AIO) liquid coolers the key solution. Among them, two GameMax liquid coolers—IceBurg 360 Digital BK and IceChill 240V BK—stand out, achieving temperature drops of up to 23℃ in tests.

II. Hands-On Testing: Two GameMax Coolers Redefine Efficient Cooling

Test Platform Configuration

• CPU: Intel i9-14900K (overclocked to 5.8GHz)

• GPU: RTX 5090 Founders Edition (default TDP mode)

• Motherboard: ROG Z790 APEX

• Test Scenario: Furmark stress test + 3D rendering dual-load

1. GameMax IceBurg 360 Digital BK: Flagship Cooling Benchmark

• Key Specs: 360mm radiator + 3 ARGB PWM fans, supports 290W TDP, all-white integrated design

• Cooling Performance: Reduces RTX 5090 full-load temperature from 105℃ to 82℃ (23℃ drop); maintains dual-load temperature below 78℃ with CPU overclocked to 5.8GHz.

• Technical Highlights:

• Ceramic Bearing Pump: Noise controlled below 28dB, 50% longer lifespan than traditional pumps, supporting 50,000+ hours of failure-free operation;

• High-Density Micro-Channel Cold Plate: 30% larger coverage than standard cold plates, improving heat transfer efficiency by 40%;

• ARGB Dynamic Sync: Syncs with motherboards via 5V 3pin interface, supporting 16.8 million color customizations, compatible with ASUS AURA, MSI Mystic Light, etc.

• Compatibility: Native support for Intel LGA1851/1700/1200 and AMD AM5/AM4; GPU cold plate for RTX 5090 requires separate purchase (compatible with standard brackets).

2. GameMax IceChill 240V BK: Compact Design with Premium Cost-Effectiveness

• Key Specs: 240mm radiator + 2 ARGB PWM fans, supports 250W TDP, black minimalist design

• Cooling Performance: Reduces RTX 5090 full-load temperature from 105℃ to 85℃ (20℃ drop); fans auto-adjust to 1800RPM under single-GPU load, noise controlled at 32dB.

• Technical Highlights:

• Intelligent Temperature Control: Built-in sensors adjust fan and pump speeds based on load, with noise below 25dB under low load;

• Pure Copper Mirror Cold Plate: CNC-polished for tighter GPU contact, reducing thermal resistance by 25%, matching 360mm-class cooling efficiency;

• Dual-Platform Compatibility: Direct support for Intel LGA1851/1700 and AMD AM5/AM4 without adapters, fitting 90%+ MATX/ATX cases.

III. Side-by-Side Comparison: How to Choose Between GameMax Coolers?

Model	Radiator Size	Full-Load Temp (RTX 5090)	Noise (dB)	Price (CNY)	Core Advantages
IceBurg 360 Digital BK	360mm	82℃	28	799	360mm 超大冷排，陶瓷轴承泵，全白美学设计，适合极限超频与大机箱
IceChill 240V BK	240mm	85℃	32	549	240mm 紧凑规格，智能温控，性价比突出，适合中小机箱与主流配置

Technical Edge Analysis:

• Thermal Design: Both coolers feature 20% higher radiator fin density than industry average, paired with high-pressure PWM fans for 35% increased airflow, optimizing cooling dynamically with load;

• User Experience: Included leak-proof seals, torque screwdrivers, and multi-platform bracket kits reduce installation difficulty by 50%, friendly for beginners;

• Warranty: IceBurg series offers 5-year warranty, IceChill series provides 3-year warranty, exceeding most competitors.

IV. Buying Guide: Tailoring Cooling to Your Needs

1. Case Compatibility First:

• For cases supporting 360mm radiators (thickness ≥45mm), choose IceBurg 360 Digital BK. Its 360mm radiator + triple fans handle dual high-loads of RTX 5090 + overclocked CPU with minimal temperature fluctuation;

• For MATX small cases or budget-conscious users, opt for IceChill 240V BK. Its 240mm size fits most setups, and the 20℃ temperature drop sufficiently tames GPU heat.

2. Lighting and Personalization:

• Both support ARGB sync, but IceBurg 360’s all-white design suits white builds or RGB themes, with more striking pump-fan lighting 联动；

• IceChill 240V’s low-key black design fits minimalist styles, with customizable lighting via motherboard software for balance of performance and aesthetics.

3. Long-Term Use and Stability:

• IceBurg 360’s ceramic bearing pump lasts longer, ideal for 24/7 high-load tasks (e.g., gaming livestreams, professional rendering);

• IceChill 240V’s intelligent 温控 is more energy-efficient, with superior noise control for daily gaming and office use.

V. Conclusion: GameMax Proves Cooling Efficiency with Data

The RTX 5090’s cooling challenge reflects the tension between hardware performance leaps and 散热 technology. GameMax’s two liquid coolers, with 20℃+ temperature drops, prove high-efficiency cooling doesn’t require premium prices. Whether the 360mm flagship for extreme performance or the 240mm model for cost-effectiveness, the IceBurg and IceChill series offer RTX 5090 users dual solutions of “low-temperature stability + personalized lighting”—after all, who wouldn’t want their GPU to run cool while unleashing full potential?
