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.

Baseline Noise


Front fan model: LI121425QE-4-A, 0.14A, 1000 RPM.


Rear fan model: LI121225SL-4, 0.27A, 1500 RPM. Note how they messed up the second set of holes preventing the fan from being uninstalled without using a screwdriver. They should be pointing in the same direction.

The LanCool PC-K59 ships with one 120 mm 1500 RPM fan and two 140 mm 1000 RPM fans, all wired with long 39 cm 3-pin cables. Molex adapters are provided for all three fans (and one extra) adding an additional 7 cm to their reach. The two fan models have similar acoustics, exhibiting very little tonality at one meter's distance. Collectively they sound quite smooth and benign, though it should be noted the rear fan is somewhat louder due to its higher speed.

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

If you have fan control at your disposal, the stock fans are reasonably quiet up to about 7V where it measures 21~22 dBA@1m. As the PC-K59 seems to be designed as a value case for a gamer/enthusiast build, 7V is probably a good starting point unless your system has exceptional cooling.


The stock fans at 7V are fairly quiet, together measuring 21~22 dBA@1m.

Hard Drive Vibration


Steadying the hard drive cages.

As there is no frame or structure on the case to give extra support to the hard drive cages, they are loose and bend from side to side with little effort. With two fingers we were able to pull the drive cages 2~3 cm to the left from their normal position. The cages rattle, particularly with a 7200 RPM drive installed, so it would be wise to steady them if noise is a concern. We did this by placing a few pieces of styrofoam around the cages to push against them to keep everything in place.
