Warning: Make sure sufficient airflow is always present around the components located below
the cooler. Different coolers are available on the market and some is not generating any airflow
or is blocking the airflow around these components, causing reduced lifetime.
Not all CPU even of same type support all functions ex. i7-4770S & i5-4570S supports VPRO other CPU types
may not. Intel® Turbo Boost Technology 2.0 is supported by i5 and i7, as indicated in above list of
processors, and is enabling overclocking of all cores, when operated within the limits of thermal design
power, temperature and current.
Note: KTH81 do not support VPRO.
Sufficient cooling must be applied to the CPU in order to remove the effect as listed in above table (Thermal
Guideline). The sufficient cooling is also depending on the maximum (worst-case) ambient operating
temperature and the actual load of processor.
It is recommended to use a cooler like the Kontron
PN 1046-6305 “KTQ77 Cooler”.
The design of this cooler makes sure airflow is
always present around the components below the
cooler. Even if Fan is set to be off, it is still running
a minimum RPM (Rotation Per Minute).
Air sucked in to the cooler
Air blown out of the cooler
Components below the cooler
Note: The temperature of the air blown out of the cooler must be less than 60°C maximum, in order not to
overheat components near the CPU. However most CPU’s requires maximum 57,4°C, so in general, not to
violate the CPU specification the temperature of the air should be maximum ~55°C. Some of the 65W CPU’s
running full load and cooled by above cooler, might start throttling at 50°C ambient air temperature.
