Black Shark FunCooler 5 Pro and RedMagic VC Cooler 5 Pro both reduce gaming temperatures, but cooling strength, mounting design, and long-session comfort create noticeable differences during competitive play.
A gaming session can begin at 120 FPS and still become frustrating 20 minutes later when rising temperatures trigger thermal throttling. Frame pacing becomes inconsistent, touch response feels slower, and smartphone surfaces become uncomfortable to hold.
Unlike many comparisons that repeat manufacturer specifications, this guide focuses on cooling efficiency, FPS stability, noise output, attachment systems, and real-world gaming performance. Additionally, practical observations from extended testing sessions reveal strengths and weaknesses that specification sheets rarely explain.
As a tech and gadget tester, I spent time researching cooling systems alongside a small group of mobile gamers. During PUBG Mobile, Call of Duty Mobile, Warzone Mobile, and Genshin Impact sessions, both cooling accessories lowered temperatures noticeably; however, mounting stability, fan acoustics, and sustained cooling performance separated the experience.
Before choosing between Black Shark and RedMagic, understanding why gaming phones overheat helps explain why external cooling can improve performance. Furthermore, gamers unfamiliar with semiconductor cooling may benefit from learning whether phone coolers actually work before investing in a cooling accessory.

How We Evaluated These Coolers
Testing focused on temperature reduction, frame-rate consistency, comfort, noise output, and ease of installation during real gaming sessions.
Rather than relying on marketing material, we used both coolers across several gaming smartphones in a room maintained between 24°C and 27°C. Additionally, testing included flagship Android devices and iPhones to evaluate compatibility.
Gaming sessions lasted between 45 and 90 minutes using PUBG Mobile, Call of Duty Mobile, Warzone Mobile, and Genshin Impact. Meanwhile, FPS monitoring tools tracked performance stability while infrared temperature measurements recorded external heat changes.
- Testing Environment: Indoor gaming setup
- Ambient Temperature: 24°C to 27°C
- Games Tested: PUBG Mobile, COD Mobile, Warzone Mobile, Genshin Impact
- Session Length: 45 to 90 minutes
- FPS Monitoring: Performance overlay tools
- Temperature Measurement: Infrared thermometer
Cooling Performance Comparison
Cooling performance remained strong on both devices, although Black Shark maintained lower temperatures during longer gaming sessions.
Several gaming benchmarks revealed measurable reductions in heat buildup compared with gaming without external cooling. Furthermore, stable temperatures helped minimize thermal throttling during demanding workloads.
PUBG Mobile Testing Results
Black Shark produced the lowest temperatures during PUBG Mobile testing while RedMagic delivered more convenient daily usability.
During Ultra HDR gameplay, Black Shark reduced rear surface temperatures faster after landing and combat-heavy sequences. Consequently, frame pacing remained more consistent during extended ranked matches.
RedMagic still performed well and kept devices comfortable to hold. However, prolonged gaming sessions revealed slightly warmer readings compared with Black Shark.
- Temperature Stability: Advantage Black Shark
- Comfort: Advantage RedMagic
- FPS Consistency: Slight Advantage Black Shark
COD Mobile Testing Results
Call of Duty Mobile benefited from both cooling systems because multiplayer matches generate sustained processor loads.
Fast-paced respawn modes exposed thermal weaknesses quickly. Nevertheless, both cooling solutions prevented the aggressive performance drops commonly associated with overheating.
Warzone Mobile Testing Results
Warzone Mobile created the greatest thermal challenge and highlighted the cooling advantage of Black Shark.
Heavy GPU workloads increased temperatures rapidly. As a result, Black Shark maintained lower peak readings while RedMagic remained competitive but slightly warmer.
Genshin Impact Testing Results
Genshin Impact demonstrated the importance of sustained cooling because open-world exploration places continuous demand on smartphone hardware.
Long exploration sessions showed fewer temperature spikes when either cooler was attached. Additionally, touch comfort improved significantly compared with gaming without active cooling.
Long-Term Durability and Ease of Maintenance
Both gaming coolers are built for daily gaming, but maintenance habits and attachment design affect long-term reliability.
After months of testing different gaming accessories, cooling performance rarely becomes the first failure point. Instead, fan wear, dust buildup, and cable stress usually determine how long a phone cooler remains effective.
Fan Reliability
Black Shark and RedMagic both use high-speed cooling fans designed for extended gaming sessions.
During repeated PUBG Mobile and Warzone Mobile sessions, neither cooler showed noticeable performance degradation. However, Black Shark’s fan housing felt slightly more robust during frequent attachment and removal.
Dust Accumulation
Dust accumulation affects cooling efficiency over time and requires occasional cleaning.
Gaming in bedrooms, offices, or living rooms gradually pulls dust into cooling vents. Consequently, cleaning fan openings every few weeks helps maintain airflow and cooling performance.
Cable Wear
USB-C cables experience the most physical stress during daily gaming sessions.
Several gamers in our testing group noticed cable strain near connectors long before cooler performance declined. Therefore, using a braided USB-C cable can help reduce long-term wear.
Cleaning Requirements
Regular cleaning takes less than five minutes and helps preserve cooling performance.
Compressed air removes most dust from cooling vents. Additionally, a microfiber cloth prevents debris from accumulating on the semiconductor cooling plate.
- Weekly: Wipe cooling plate surface
- Monthly: Clean fan vents
- Every 3 Months: Inspect cable connectors
- As Needed: Remove trapped dust particles
Condensation Risk and Safety
Quality semiconductor coolers are generally safe for smartphones when used correctly.
