This section allows viewing and controlling the fans speed. Two modes are available to control the fans
"Switch to Manual Speed Control" or "Switch to Auto Temp Control". Click the corresponding button to
switch them. Only the manual mode can be used to modify the memory fan controls. The KTC5520/EATX has
seven fan headers (CPU0 Fan, CPU1 Fan, Mem0 Fan, Mem1 Fan, Sys1 Fan, Sys2 Fan and Sys3 Fan). Their
location can be found in the Quick Reference Sheet and the rating for each fan is: Max 1.5A over 12V (18W).
By default, automatic mode is selected. Targeted temperature, high and low tolerance and maximum and
minimum fan speed need to be set. Fan speed range is from 0 to 63.
The second one is the manual mode and only target speed setting can be adjusted. The lowest value is 0 and
maximum speed is 63.
To activate the new configuration, the button "Set New Speed" must be click.
