For anybody sick and tired of the generic responses, such as: "check chassis intrusion", when it does not come with a chassis intrusion switch..... etc, etc....
I found that for this product, Intel have set the minimum fan speed in the SDR config quite high. This is expected behaviour. Unless you manually edit the SDR, this will be the minimum fan speed.
I am not sure how they think that the constant volume of noise produced is acceptable.
As mentioned in my previous post, Intel have set the minimum fan speed quite high. My apologies, I did not mention that Intel support called me. According to them, it is something like 7500 RPM in version 15, and 5500 RPM in previous versions. If that is the case, no amount of following copy paste directions will change what they have put in the SDR included with the firmware.
