Thermaltake CT140 PC Cooling Fan (2-Pack) - Quiet High Airflow

In this review of the Thermaltake CT140 PC Cooling Fan (2-Fan Pack) the bottom line is simple: these 140 mm PWM fans are best for builders who want a quiet, high-airflow upgrade without complex wiring. The reviewer found the daisy-chain cable design and seven-blade geometry deliver measured airflow and improved case ventilation while keeping noise subdued, making them a practical choice for most mid-tower and older cases. Installation was straightforward and the overall fit, finish, and value make these fans a solid add-on for system cooling improvements.

Key Features

• Redefined 7-blade design: Tuned blades push air further to improve case ventilation and contribute to a measurable temperature drop under load.
• Daisy-Chain cable integration: Fewer cables and ports are required, which simplifies cable management and reduces clutter in tight builds.
• PWM control up to 1500 RPM: Variable speeds let the system balance cooling performance with quieter operation during light use.
• Optimized hydraulic bearing: The bearing design keeps long-term reliability high while maintaining near-silent operation during typical workloads.
• Anti-vibration mounting: A solid frame and anti-vibration pads reduce transmitted noise and improve perceived build quality.

Who It's For

The CT140 pair is aimed at PC builders and upgraders who want reliable airflow improvements without spending on premium RGB or specialty fans; it is especially useful in older cases where airflow was limited and cable routing is a problem. Its balance of airflow and noise makes it a good choice for quiet gaming rigs, workstations, and home servers where steady cooling is needed.

Users who need extreme static pressure for dense radiators or want full-color RGB lighting should look elsewhere, since these fans focus on practical airflow, silent bearings, and cable simplicity rather than RGB effects or maximum radiative pressure ratings.

Pros & Cons

Pros

• Quiet operation backed by an optimized hydraulic bearing and modest 1500 RPM top speed.
• Noticeable airflow improvement in real builds thanks to the tuned seven-blade geometry.
• Daisy-chain wiring reduces cable clutter and frees up motherboard fan headers.
• Solid build quality and anti-vibration mounting make them feel durable and snug in most cases.

Cons

• Not targeted at users who need maximum radiator static pressure or built-in RGB effects.
• Rated airflow and pressure figures are balanced but not extreme for specialist cooling demands.

Frequently Asked Questions

Are these fans compatible with standard 140 mm mounts?
Yes, the CT140 uses standard 140 x 25 mm dimensions and fits typical 140 mm case mounts and brackets.

Can I control fan speed from the motherboard?
Yes, the fans use PWM control so speed can be managed from a compatible motherboard header for a balance of noise and cooling.

Will the daisy-chain cable reduce available fan headers?
The integrated daisy-chain design reduces the number of separate cables you need, so it helps preserve motherboard fan headers rather than consume more.
