I was asked to report temperature with my air cooling mod. I finally got my thermocouple temperature unit, installed hddtemp and got the following results:

hddtemp /dev/sda 25 degC, ambient 18 degC, 7 vdc on the cooling fan and idle B3 load.

su_root - I agree with your approach, getting the power out of the case is a great way to avoid cooling concerns. When I first looked at the B3, what I wanted was a 240GB SSD but that is not an option. I considered buying one anyway and using the HDD somewhere else. The SSD I was considering (and st...

Because of some forum comments, I am left with the impression that information I did not take time to present would be useful in understanding why cooling is important and the effects of air flow. Semiconductor life is directly related to temperature. A doping material (like Boron) is diffused into ...

Puma - Nice work and nice pictures. I have a suggestion: remove the cool plates and just let the fan blow on the B3 units. The B3 case IS the heat spreader and the heatsink. The cool plates introduce additional thermal resistance between the source (B3) and the sink (air flow). Removing the plates w...

Johan - Yes there is a lot of text. It was my effort to be helpful. I did not do any measurements on noise or temperature, nor will I. With an 80mm fan at 6v it is inaudible. The temperature will depend on how hard you are running the system and the fan speed. Any airflow will have a significant coo...

Here are the other 3 pictures:

In discussing another matter with Johannes at Excito, I included some pictures of the fan modification I did on the B3 and he asked me to post them here. Semiconductor life is dramatically improved with cooling and I am always concerned about this and willing to spend some time and effort if needed....
