Chieftec DX-01BLD in the test: Insulation for the CS-601 ex works

Test results

The usual test system was also used for this test, only the graphics card made room for a GeForce 4Ti4200. Of course, we were very curious to see how the volume and temperature would change in contrast to the Koolance or normal uninsulated CS-601 . Unfortunately, there is no sound level meter available at the test location, so the purely subjective impression is given here. The CS-601 is of course the loudest, with three case fans, which makes a decent background noise. The Koolance, on the other hand, can almost be described as quiet, provided with a case fan and the three fans above the radiator. Both of them are not only annoyed by the noise of the fans, but above all by the high-frequency running noise of the three installed hard drives with 7200 rpm each. With the insulated CS-601, this sound is practically no longer audible. The access noises can only be heard very quietly and not annoyingly when the hard disk heads move a lot. Even the DVD drive, which is certainly not exactly quiet, is tamed and no longer interferes with watching quiet movie scenes. Only the fan in the side door and the two fans of the Leadman 400 watt power supply are noticeable.

Now we come to the temperature development: The existing sensors of the A7V333, the processor and the hard drives are used and via the motherboard monitor (MBM ) read out.

Of course, the CPU temperature of the Koolance cannot be reached with the purely air-cooled systems. However, the difference between the CS-601 and the insulated CS-601 is more interesting here. Despite the significantly reduced volume, the temperature of the processor in the insulated model is only about 2 ° C higher under otherwise identical conditions. The measured temperature of the board itself is even lower, but the different arrangement of the case fans must be taken into account. In contrast to the uninsulated, old CS-601, the insulated CS-601 model already has the housing fan integrated into the side door, through which the fresh outside air is blown directly onto the board. The dreaded heat death due to the insulation is with the 'be quiet' insulation mats usedso not to be expected. Despite the lack of active ventilation, the HDD temperature is also in a comfortable range and even about the same level as the uninsulated CS-601, although there was an 80mm fan directing fresh air into the inside of the case via the HDDs.
