A bit bigger (XL) midi-tower… Endorfy Arx 700 Air test

Test methodology

The all-new Arx case range has just made its debut. The first model, the 700 Air, is also the largest case from Endorfy. This case is equipped with up to five 140mm fans, which in combination with the ventilated front panel create a great potential for really powerful or very efficient (i.e. at lower rpm per unit of airflow also super quiet) system cooling. This then naturally has a positive effect on the results.

Test methodology

A total of five Stratus 140 PWM fans take care of cooling the components in the case. Three are mounted at the front for intake and two at the rear for exhausting excess heat from the case. Ideally, this amount of fans should easily handle cooling even the more demanding, higher power hardware.

Testing is done in a home environment where I strive for the most accurate results possible. In the room during testing, the air temperature in front of the case is 23 degrees Celsius and the minimum noise level I can measure with the Voltcraft SL-100 noise meter is 32.4 dBA. The sensor of the noise meter is aligned to the center of the top of the case at a distance of 10 cm, for the best measurement of the speed difference of the fans, which I change using the motherboard. For easy comparison to other cases, they are always regulated to fixed noise levels.

Individual components are heated for 10 minutes in FurMark synthetic stress tests and with Prime95 (custom settings) at the same time. This time is long enough to allow all components to warm up sufficiently. There are then 15-minute cooling breaks between tests, during which the component temperatures (and the case air temperature as well) are brought back to default.

Noise mode levels:

• 36 dBA
• 38 dBA
• 39 dBA
