Enthusiasts who wanted to improve their system performance through cooler temperature and quieter operation found aftermarket GPU coolers to be the most effective solution during the late 2000s. The Thermaltake DuOrb displayed distinctive design elements through its one-of-a-kind appearance and its original method of thermal management which distinguished it from other products that emerged during that time. Thermaltake created the DuOrb product through its development of two circular heatsink elements which formed the basis for its design according to the product name DuOrb.
The cooler belonged to Thermaltake’s Orb series which had established itself in the market through its Golden Orb and Blue Orb CPU cooler products. The DuOrb continued this tradition while targeting graphics cards that required stronger cooling.
Design and Construction
The most noticeable feature of the DuOrb is its dual circular heatsink layout. The cooler has a symmetrical appearance because each “orb” features copper fins with a fan installed above them.
Key hardware features include:
The heatsink design uses all-copper materials
The system contains two 6 mm heatpipes
The device includes dual 80 mm fans
The system uses a mirror-polished copper base
The fans display blue LED lights
The cooler system uses heatpipes to move heat from the GPU core to two fins which the fans use to send heat into the surrounding environment.
The two-part heatsink design allows airflow to cover a wider portion of the graphics card which results in better cooling performance for memory chips and power circuits.
Cooling Performance
DuOrb delivered decent cooling results at its release point because it outperformed multiple standard GPU cooling solutions.
Testing on GeForce 8800 GTS GPUs demonstrated substantial performance improvements. The DuOrb achieved temperature reductions of approximately 20 °C during idle periods and 12 °C during load periods while using identical thermal paste to the stock cooler.
The following elements contributed to these augmented improvements:
The heatsink size now has more surface area.
The heatpipe system now uses direct thermal contact with the GPU base.
The dual-fan system provides complete airflow distribution throughout the graphics card.
The cooler maintained temperature stability throughout demanding operations even when its fans operated at reduced speed settings.
Noise Characteristics
DuOrb received multiple complaints about its noise levels although it demonstrated effective thermal management capabilities.
The two 80 mm fans run at relatively high speeds—around 2500 RPM—to provide sufficient airflow through the copper fins.
The cooler produces significant noise levels when it functions at maximum operational capacity. Some reviewers even described it as one of the louder GPU coolers in its category unless the fan speed is reduced.
Many users solved this issue by connecting the fans to a fan controller or undervolting them to reduce RPM.
Compatibility
The DuOrb was designed for several high-end graphics cards from the mid-2000s era. The following GPU models received official support:
The NVIDIA GeForce 8800 series
The GeForce 7900 and 7800 series
The GeForce 6800 series
The ATI Radeon X1900 and X1950 series
The Radeon HD 3800 series
This made it a practical upgrade for many performance GPUs of that generation.
Its slim design permitted installation of the product in one extra expansion slot which made it more compact than various other aftermarket coolers.
The installation process required the removal of the original GPU cooler to install the DuOrb system. The process generally included: The stock heatsink from the graphics card system was removed The system required new thermal paste to be applied The DuOrb system was installed through its mounting bracket The system required small heatsinks to be installed on memory chips The system required fans to be connected to a power source The installation process allowed experienced PC builders to complete their work but users found the mounting system difficult to operate when compared to mounting systems found in other cooling solutions.
Advantages and Drawbacks The cooler has two main benefits which exist as its main design element. The dual-orb structure and blue LED fans gave the cooler a very recognizable appearance. The system provides excellent cooling because it maintains GPU temperatures at lower levels than many stock cooling solutions. The DuOrb system required only one additional slot because it did not need multiple slots like other large aftermarket coolers.
Drawbacks The dual fans operate at high speeds which creates discernible sound output. The system has reduced cooling power because it only uses two heatpipes which limits its performance compared to larger cooling systems. The system included basic memory heatsinks which had limited cooling capabilities.
Overall Impression
The Thermaltake DuOrb stands as an important historical artifact which demonstrates the development of GPU cooling technologies. The dual-orb design together with its copper body and LED lights created a visually distinctive aftermarket GPU cooler design which stood out from other products of its era. The product delivered good performance which exceeded many reference coolers but its fan operation created a noise problem which needed fan management to solve.
The DuOrb serves as a historical representation of a time when PC users tested various cooling methods to achieve higher performance because modern GPUs now utilize advanced thermal management systems. The product gave users during that time period an enjoyable experience which delivered better performance than their existing GPU cooling solutions.
