ZM-NC3000U is aimed at laptops ranging from 9’’ to 17’’. This might prove to be quite popular with users, especially those with larger and hotter laptops. The implemented fan speed regulator will allow for manual regulation and finding that perfect balance between noise and cooling.

The fan is very quiet at minimum RPM, almost inaudible. That’s not to say that maximum RPM of 720 is loud, as we found it to be acceptable.

We used two laptops for our testing - a slightly older HP Pavilion DV9000 and the new Sony Vaio VPCEB1M1E. We stressed the laptops using Prime 95 and got the following results:

First test used the 17’’ HP Pavilion DV9000 with Mobile AMD Turion 64 X2 dual-core, notable for bad heatsink design and prone to overheating. As you can see, Zalman’s ZM-NC3000U took care of that in no time.

The second test used a few months old 15,5’’ Sony Vaio VPCEB1M1E running on Intel’s Core i7 330M CPU
