The EISCA(Enhanced Intelligent System Cooler Architecture)

is a specially designed 12-pin interface which integrates the

Mainboard and the CPU cooling system. This system is a total

solution for PC system heat sink problems.

Due to increasing CPU speed, which causes higher

temperatures, finding ways to effectively deal with CPU

temperatures is becoming a more and more crucial problem.

Effectively and precisely determining CPU temperature was a

very important requirement. The area directly under the CPU

socket is the location on the mainboard. closest to the CPU,

and heat is conducted away from this area through air

circulation. Determining temperature change under

these circumstances is very imprecise, as it only allows us to

detect large changes in temperature. In addition, because the

air under the CPU socket is confined to this area, the sensor

cannot detect temperature in real time. Tests have proven that

under such circumstances, even after 5 minutes the sensor

located under the CPU socket is unable to detect real

temperature change, so it can not meet the requirements for

thermal problems.

In EISCA architecture, the thermal sensor is located at the

heat-sink. In this way, the sensor is able to detect CPU

temperature in real time and more precisely. The EISCA

monitors voltage, fan speed and fan on/off control to meet the

important specifications.
