TESTING

As the case interior is almost identical to the RV02, and there are no changes to the exterior/frame to affect thermal performance, we opted not to run the FT02 through our usual, rigorous testing procedures. For thermal results, see our Raven Two review; there should be no appreciable difference between the two.

Though the fans included are the same as the RV02, we tested the baseline noise of the case, as the padded side panels, lack of a side window and case feet could create changes in acoustics.

BASELINE NOISE

Noise measurements were made of the case with the stock fans mounted normally and spinning inside at various speeds. The air cavity resonances inside a case amplify fan noise, as do any vibrations transferred from the fans into the case, so these measurements can be regarded as the baseline SPL levels for the case. Adding components can only increase the noise.

Like the Raven Two, the perceived noise was moderate even with all fans at full speed. The overall character was smooth and benign. The only consistent difference between the baseline noise of the RV02 and FT02 seems to occur when two or more of the intake fans are set to high speed. The FT02 measured about a decibel higher, possibly as its 180mm fans face an aluminum floor while the RV02's fans faced the carpet of our anechoic chamber. In any event the difference is probably not possible to hear without a very close A/B comparison. A single dB is within our margin of error due to the many variables of acoustic testing.
