Zalman Notebook Cooler ZM-NC2000 Review and Benchmark

Zalman is well known for its cooling products; I have been using them for several years, so when I needed something to keep my laptop cool, they were the first company I looked up to.

Notebook Cooler Construction

The Notebook Cooler is large enough to hold my Pavilion DV7 and also acts as a keyboard riser, making typing more comfortable. The construction is made of thick aluminium, which is naturally cold to the touch. It is powered by a spare USB port on the laptop; the Zalman Notebook Cooler fan is loud enough to be heard but much quieter than the laptop fans when they spin up, so the overall noise is reduced considerably. The ZM-NC2000 features an additional USB port, so you do not lose out on the number of ports. The surface is made from aluminium to conduct heat more effectively, while the underside is plastic.

There is an on/off toggle button and a dial to control the fan speed. On maximum settings, it can be quite loud. Still, about 30% is sufficient to keep laptop fans off under moderate usage. I turn it up for gaming to around 75%, which is still quieter than the laptop fans spinning up.

ZM-NC2000 Notebook Cooler Performance Table

The table below shows the difference between no cooler, passive cooling (fans off) and active cooling (fans on 50%). Temperatures measured with SpeedFan 4.49

Test Temp CPU Temp GPU Temp HDD Temp Core
Idle (no cooler) 46°C 46°C 32°C 46°C
Load (3DMark11) (no cooler) 89°C 90°C 36°C 90°C
Idle (passive cooler) 41°C 41°C 33°C 40°C
Load (3DMark11) (passive cooler) 57°C 57°C 34°C 56°C
Idle (active cooler) 38°C 42°C 32°C 38°C
Load (3DMark11) (active cooler) 54°C 53°C 32°C 55°C

These results certainly speak for themselves and show the Zalman Notebook Cooler ZM-NC2000 effectively provides additional cooling for laptops. Highly recommended, although this only works well for laptops which have an intake air vent in the base. If the intake vents are on the back or sides, this will likely do little to aid your temperatures and noise levels.
