Design and Functionality

At first Thermaltake DuOrb reminds us of Zalman VF900 LED cooler times 2:

The skeleton of Thermaltake DuOrb is made of two copper heatpipes 6mm in diameter that originate from a copper base. They carry a lot of copper plates cooled with a pair of fans:

We can say that this cooler is shaped as an “8”, which we have already mentioned in our news stories about it.

Thermaltake DuOrb measures 180.5 x 98.5 x 30mm and weighs 324g.

The cooler base is very even (we checked it using our thermal paste imprint method on the glass surface and then on the GPU), however it lacks Thermaltake’s traditional shining finish, which we often see on other cooling solutions from this manufacturer:

Two TT-8015L fans are 80x15mm big and feature blue lighting:

The fans rotate with constant speed of ~2500RPM and create 23.8CFM airflow. The manufacturer doesn’t report the level of generated noise for some reason, but against the competitors’ background it seemed subjectively louder. We don’t know why the new cooler has no fan rotation speed controller or a 5/7V converter. The fan bearing mean time before failure is claimed to be 50,000 hours.

Thermaltake DuOrb is designed for Nvidia 6800/7800/7900/8800 and AMD X1800/X1900X/X1950 graphics cards. It also fits perfectly fine onto Radeon HD 2900/3850/3870 graphics cards that are not in this list.
