80 mm PWM case fan

The 1ST PC CORP. EFC0812DB-PWM is an 80 mm case fan built around a dual ball bearing and a 4-pin PWM connector. It spins up to 3800 RPM while delivering 48.8 CFM of airflow at 41 dBA. Rated voltage is 12 VDC with an operating range of 7 to 12.6 VDC. The low-profile frame measures 80 x 80 x 15 mm.

Who it suits and who should look elsewhere

This fan suits builders who need a thin 80 mm cooler with PWM speed control for tight chassis spaces. It is not for buyers who require a larger frame size, higher static pressure for dense radiators, or a quieter acoustic profile below 41 dBA at full speed.

Deciding specification: 80 x 80 x 15 mm frame

The 15 mm thickness determines whether the fan fits in slim enclosures or between closely spaced components. Verify the available clearance in your case before purchasing.

The Delta EFC0812DB PWM is a medium high speed, low profile cooling fan at 80 x 80 x 15mm. Its PWM output can give you the best balance between quietness and cooling when you need it. Its low profile means that itt can be placed into tighter spaces where air cooling is needed. Air flow is a very healthy 48.8 CFM at a relatively quiet 41 dBA at maximum, or 1.382 cubic meter per minute. However, when CPU is

Soalan tentang produk ini

Does the 80mm fan include mounting screws or do I need to buy them separately?

The 80 x 80 x 15mm unit is supplied as the fan only; standard M3 case-fan screws are not included and must be purchased separately.

Should I choose the 3800 RPM version or a lower-speed model for a noise-sensitive build?

At 3800 RPM the fan delivers 48.8 CFM and 41 dBA; PWM control lets it drop well below those figures when the CPU is lightly loaded, so the same model covers both performance and quiet operation.

What does the 48.8 CFM rating mean once the fan is installed in a real case?

It moves 1.382 cubic metres of air per minute at 4.35 mmH2O static pressure, giving strong airflow through meshed panels or heatsink fins while running at 12 VDC and 0.33 A typical.
