140 mm high-speed case fan

The SXDOOL dbpc1438b2h is a 140 mm case fan built for systems that need strong airflow. It runs on 12 V DC and uses a 4-pin PWM connector for automatic speed control. The dual ball bearing supports continuous high-speed operation. This unit suits mining rigs, servers or workstations where thermal headroom is critical.

Upgrade from standard 140 mm fans

Most stock 140 mm fans top out well below 6500 RPM, so this model replaces them when components run hot under sustained load. The jump is worth it when your chassis can feed enough fresh air to match the exhaust rate. Builders who already hit thermal limits with conventional fans will see the benefit immediately.

Suits high-density mining and server builds

This fan fits builders who need maximum airflow from a 140 mm frame and accept the resulting noise level. It is not for quiet home-office PCs, living-room HTPCs or any system where low acoustic output is a priority. Buyers who need PWM speed curves below 6500 RPM should look at lower-speed alternatives.

Questions about this item

Will the 140mm by 38mm frame fit my case's 140mm mounting points?

The fan measures 140mm square and 38mm thick, so it fits standard 140mm mounting holes provided your case allows a 38mm depth.

How do I connect the 4-wire PWM cable for proper speed control?

Plug the 4-pin connector into a motherboard PWM header; the fourth wire carries the PWM signal so the board can vary the 6900 RPM maximum.

When should I expect to replace the dual ball bearing?

Dual ball bearings typically run for years at 6900 RPM; replace the fan if noise increases or speed drops below the 6500 RPM lower range.
