TESTING

System Configuration:

Measurement and Analysis Tools

System temperatures and noise levels were recorded with SpeedFan and GPU-Z at idle and on load using CPUBurn (K7 setting) and FurMark, an OpenGL benchmarking and stability testing utility.

Measuring mic positioned 1m at diagonal angle left/front of case.

The Temjin TJ04-E ships with three identical 120 mm fans with the model number "HA1225L 12SA-Z," which we've seen before most recently in the Fortress FT03 and Raven RV03. It's a 3-pin, 0.33A model with a nominal speed of 1200 RPM. It's not particularly quiet and emits a tiny amount of bearing chatter, but overall, it has a very nice, smooth sound.

Though the front fan is on the opposite side of the case from our mic, it measured the loudest at 25 dBA@1m at 12V. The rear fan was moderately quieter, and the top panel fan was quieter still. The quality of the noise didn't noticeably vary between the three positions. The combined noise level was a reasonably quiet 19 dBA@1m at 7V, 24 dBA@1m at 9V, and 29 dBA@1m at 12V.


At 7V, the stock fans produced a noise level of 19 dBA@1m and had a fairly smooth, broadband character.

Hard Drive Vibration

More often than not we run into cases with a hard drive vibration problem. Typically this happens when the hard drive cage is not sufficiently secured to the rest of the chassis or if the side panels are loose; in the case of the TJ04-E, it's a combination of both. Upon turning on our test system, we could feel and hear the left side panel vibrating, but it disappeared when the panel were braced with our hands.


A small modification to reduce vibration.

The vibration issue wasn't a complete surprise given how the HDD cage has complete support on one side, and we've definitely encountered a lot worse in the past (the TJ08-E was terrible in this regard). Applying some styrofoam to the hard drive cage to brace the side panel helped dissipate much of the vibration.


There was a slight reduction with the side panel braced.

Acoustic analysis showed a small improvement in acoustics; the ~120 Hz tone produced by the rotation of the drive decreased by 5 dB, resulting in an overall noise reduction of ~0.5 dBA.
