The heat exchanger is located at the bottom of the case.
Since the two cooling elements for the processor and graphics card did not exhibit any abnormalities, nor could its conventional type of construction produce any faults, we searched for the reason for the poor cooling efficiency in the heat exchanger. The heat exchanger is located beneath the base of the case.
Far too small in size: The three miniature fans are not capable of generating a sufficient air flow for the heat exchanger.
Useless: The right-hand fan blows air ineffectively against the metal wall of the heat exchanger. Only the two other fans transport the air flow along the cooling fins of the heat sink.
The problem is clearly visible in this photo: The right-hand fan blows against the wall of the heat sink.
Koolance has, however, performed its work well in one respect: Great care has been taken in assembling the system, and what are in some cases hand-built components have been worked to fit exactly in place.
