Cooling System And Heat Levels
It is hard to say anything about the CPU fan, because it is not included in the package. However, the boxed cooler from Intel fits easily into the QBic EQ350I. There is lots of leeway between the power supply and the drive chassis, so that most socket-775 fans can be used. The negative aspect about the boxed cooler is the fan, which reaches up to 4,440 rpm when the CPU is at full capacity. That's not just loud - it makes the PC noticeably vibrate. With one further test cooler-the Coolermaster CI5-9HDPA-02*- the vibrations at least disappeared, but the noise remained at a very high level.
