Pros & Cons
👍 Pros
- All-aluminum construction doubles as a passive heat sink for better thermal dissipation
- Dual fans operate at only 21 dBA, making the cooler nearly silent during use
- Two USB 2.0 passthrough ports let you connect peripherals without losing port access
- Powered directly from the laptop's USB port — no external adapter needed
- Low-profile 42 mm height adds minimal bulk while providing a comfortable typing angle
👎 Cons
- 70mm fans deliver only 10.5 CFM of airflow, which may be insufficient for high-performance gaming laptops
- Sleeve bearing fans have a shorter lifespan compared to ball bearing alternatives
- USB 2.0 ports limit transfer speeds for connected peripherals to 480 Mbps
- No adjustable fan speed control — fans run at a fixed 1500 RPM
- Maximum compatibility stated at 15 inches, leaving larger 17-inch laptop users without support
Frequently Asked Questions
What size laptops does the Cooler Master NotePal support?
The NotePal is compatible with most 15-inch notebooks, including widescreen models. Its 320 x 300 mm surface accommodates standard and wide-format 15" laptop footprints.
How loud are the fans on this cooler?
The dual 70mm fans operate at just 21 dBA, which is quieter than a whisper and virtually inaudible in a normal room environment.
Does the NotePal require its own power adapter?
No. The NotePal draws power directly from your laptop through its USB connection, so no separate wall adapter or batteries are needed.
Does the cooler have USB passthrough ports?
Yes, it includes two USB 2.0 ports, so you only sacrifice one USB port on your laptop while gaining an additional one.
What material is the cooling surface made of?
The entire cooling surface is constructed from aluminum, which acts as a passive heat sink in addition to the active fan cooling.
