High-speed 140 mm case fan
The BGears b-BlasterPWM 140x38 is a single 140 mm case fan built for systems that need a wide speed range. Its 1200 to 6500 RPM span lets the PWM curve match cooling demand precisely. Japanese dual-ball bearings support the high rotational speeds. The unit suits builders who want strong airflow without LED lighting.
Sustained-load airflow and pressure
At the top of its range the fan moves up to 398 CFM and develops 37.03 mmH2O static pressure. The 38 mm thickness helps maintain that pressure through restrictive radiators or dense mesh. Noise reaches 67.8 dBA at maximum speed, so the curve should be tuned for the workload. MTBF is rated at 70000 hours for continuous operation.
38 mm thickness constraint
The 38 mm frame depth decides whether the fan fits your chassis or radiator stack. Standard 25 mm mounts will not accept it. Buyers with slim cases or tight clearance above the motherboard should verify spacing before ordering. The four-pin mini connector provides standard PWM control.

Soalan tentang produk ini
How loud is the BGears b-BlasterPWM 140x38 when running continuously at its 6500 RPM maximum?
The fan reaches a maximum noise level of 67.8 dBA at 6500 RPM, while PWM control lets it drop to 1200 RPM for much quieter operation during lighter loads.
Does this 140 mm PWM fan need a separate controller or can it plug straight into a motherboard header?
It connects via a standard 4-pin PWM header and includes its own PWM speed control function, so no external fan controller is required.
Will the 38 mm thickness fit alongside standard 25 mm fans in a push-pull radiator setup?
At 38 mm thick the fan is significantly deeper than typical 25 mm models, so you must verify case and radiator clearance before mixing thicknesses.
