Size, Speed, And Noise
Fan Size
The Thermaltake Pure 20 measures 200mm in diameter, making it a large chassis fan designed for high air pressure and airflow. It is built to move significant volumes of air within a case. The GDSTIME fan is much smaller, with a 70mm diameter. This compact size is intended for CPU coolers or tight spaces where larger fans will not fit. You must choose based on your case dimensions and where the fan will be mounted. The 200mm model offers broader coverage, while the 70mm unit targets specific, smaller cooling components.
Airflow
Specific airflow figures are not listed for the Thermaltake Pure 20 in the provided data, though it is described as having high airflow. The GDSTIME fan provides a rated airflow of 18.7 CFM. This metric indicates the volume of air it moves per minute. Without a comparable number for the Thermaltake unit, a direct numerical comparison is not possible. However, the Thermaltake is engineered for high performance in chassis ventilation, while the GDSTIME offers moderate airflow suitable for its smaller size and CPU cooling application.
Noise Level
Noise specifications are not provided for the Thermaltake Pure 20 in the data. The GDSTIME fan has a rated noise level of 25.8 dBA. This decibel rating helps you gauge how loud the fan will be during operation. The Thermaltake is marketed as a quiet fan with enhanced airflow that reduces noise, but exact figures are absent. You will need to rely on the GDSTIME’s 25.8 dBA rating for a concrete noise benchmark, while the Thermaltake’s noise performance remains described only in general terms.
Connector Type
The GDSTIME fan uses a 3-pin connector, which allows for DC speed control via motherboard headers. The Thermaltake Pure 20 data does not specify its connector type. Most modern chassis fans use 3-pin or 4-pin PWM connectors for speed regulation. Since the connector details for the Thermaltake are missing, you should verify compatibility with your motherboard before purchasing. The GDSTIME’s 3-pin interface is clearly defined, ensuring it fits standard DC-controlled fan headers.
Bearing Type
Both fans utilize sleeve bearings, which is a common choice for cost-effective and quiet operation. The Thermaltake Pure 20 features a long-life sleeve bearing designed to extend the lifespan and improve reliability. The GDSTIME fan also uses a sleeve bearing with a rated life of up to 35,000 hours at 25 degrees Celsius. This shared technology suggests both products aim for dependable performance over time. The Thermaltake emphasizes longevity, while the GDSTIME provides a specific hour rating for its bearing durability.
Which case fan fits your build
Standard PC case builder needing high airflow
The Thermaltake Pure 20 measures 200mm, making it a large chassis fan designed for high air pressure and airflow. Its 30mm thickness helps focus airflow while reducing noise. This size is ideal for moving significant volumes of air within a standard computer case to keep components cool during heavy loads.
Upgrading small form factor CPU coolers
The GDSTIME fan is only 70mm wide and 15mm thick, fitting directly onto small CPU coolers. It offers 18.7 CFM of airflow at 2500 RPM. The 3-pin connector and 12V rating ensure compatibility with standard motherboard headers. This compact size is essential for tight spaces where larger fans cannot fit.
Seeking reliable operation with low noise
Both fans use sleeve bearings, but the Thermaltake model emphasizes silence alongside efficiency. Its larger blade surface area allows for lower RPMs while maintaining high airflow. This design creates a torrent of air without excessive noise, providing a quiet computing experience suitable for home offices or media centers where sound matters.
