LEPA 70D (LP70D12R)

LEPA is represented in this review with four new fans. First goes the 70D (LP70D12R) model. Its compact cardboard box has a large plastic window through which you can view the impeller. The product’s key features are also mentioned there.

Detailed specs are listed on the back. The fan is shipped together with mounting screws and a PATA power adapter for a 12V, 7V or 5V source.

The fan is manufactured in China and costs about $10. The warranty period is 1 year.

The LEPA 70D is very light at only 107 grams. It has the classic design of a 120mm fan: a black plastic frame and a dark-gray 7-blade 111mm impeller.

 

LEPA engineers must have taken it easy with the 70D, developing an absolutely unremarkable product.

The rated speed is 1600 RPM but you can lower it with the adapter to 1200 or 900 RPM by connecting to 7V and 5V sources, respectively. The peak air flow is specified to be 64.5 CFM at 24 dBA of noise and a static pressure of 1.9 mm of water. These parameters change when the fan is connected via the adapter as listed in the table above.

The plain-looking LEPA 70D can boast one special feature. It is the original self-lubricating Barometric Oil-less bearing with low rolling resistance and a long service life of 100,000 hours. One more feature of the fan is that it is capable of functioning at ambient temperatures up to 70°C. It’s up to you to decide whether that’s useful for a PC or not.

The motor is 40 mm in diameter. You can learn its manufacturer name, model number, electrical specs and country of origin from its sticker.

The peak power consumption of the LEPA 70D is 3 watts at 0.25 amperes. It is average in terms of power requirements.

The impeller can be taken off for cleaning and lubricating as necessary.

The electric motor is nothing special but it’s good to see two capacitors here.

 

The flat 3-wire cable is 500 mm long.
