Black Shark Phone Cooler FunCooler 3 Pro - Fast, Quiet Phone Cooling

In this review the Black Shark Phone Cooler FunCooler 3 Pro is evaluated as a targeted accessory for mobile gamers and heavy phone users who need sustained performance. The bottom line: it excels at rapid, sustained temperature control with a semiconductor heatsink and 20W cooling power, making it useful for long sessions that tax battery and CPU. It is not a universal cure for every device heat issue, but for phones that fit its 2.63-3.46 in clamp range it delivers noticeable cooling and helps prevent throttling in extended play.

Key Features

• 20W cooling power: The strong cooling output reduces surface temperature quickly so phones can maintain peak performance during long gaming sessions.
• Rapid 3-second start: The unit begins active cooling within seconds, offering immediate reduction in device temperature at the start of demanding use.
• Large cooling chip: A 1404mm2 semiconductor heatsink provides three times the cooling effect of ordinary phone coolers, improving sustained heat dissipation.
• Vertical air outlet: Heat is discharged up and down to avoid hot air recirculating onto the phone, which helps keep the device cooler over time.
• App and Bluetooth control: The companion app allows intelligent temperature control, RGB settings and a sleep timer for customized operation and automated shutdown.
• Quiet fan: The silent fan design provides active, fan-assisted cooling without noticeable distraction during gameplay or video playback.

Who It's For

This cooler is aimed at mobile gamers, streamers and power users who run prolonged, CPU- and GPU-intensive apps and need to limit thermal throttling. The FunCooler 3 Pro best suits phones with widths from 2.63 in to 3.46 in and owners who want app-based controls and customizable timers.

Those who rarely push their phone or who use devices outside the stated width range should look elsewhere; some users report mixed results on absolute temperature drop depending on phone model, and prolonged non-gaming use is discouraged to avoid condensation risk.

Pros & Cons

Pros

• Powerful 20W semiconductor cooling that often reduces throttling during extended gaming.
• Very fast start: noticeable cooling effect in about 3 seconds.
• App control and timer let you automate temperature and RGB behavior.
• Quiet operation that does not distract from gameplay.

Cons

• Fit is mixed across some phones; a few users found the clamp short or incompatible with larger cases.
• Some reports show phones feeling hotter on certain models, so results can vary by device and usage scenario.

Frequently Asked Questions

Will this cooler fit my phone?
The clamp fits phones between 2.63 in and 3.46 in wide (67mm-88mm); measure your phone and case to confirm compatibility.

Does it work silently during gaming?
The unit uses a silent fan design to minimize noise while providing active cooling, so it should not distract during gameplay.

Can I leave it running all the time?
It is recommended to avoid prolonged non-gaming operation to reduce the risk of condensation inside the phone; use the app timer for safer automated shutdown.
