With AMD platform substantially keeps increasing the speed of its CPU, it inevitably led to the
annoying problem of high CPU operation temperature at the same time. In order to prevent
accidental failure of CPU fan, which could cause the burning down of the AthlonXP CPU, we, AOpen, have meticulously
developed a new technology, named, O.H.P. (Overheat Protection) Technology to protect them. Thanks to the intelligent
monitoring design of AOpen O.H.P. technology, user can now finally set their mind at ease even when fan failed to work without
fearing the possible damage of CPU.
Under the circumstances that CPU fan is running properly, AthlonXP temperature should be way below the highest temperature
limit of 97℃. However, if CPU fan accidentally becomes malfunction or improperly installed, the CPU temperature would rocket

abruptly, and you may find your system hang up or crying over the
smoking CPU if you haven't installed AOpen O.H.P. previously. With
AOpen O.H.P. technology applied, the specific thermal detection pins on
AthlonXP CPU would sense voltage difference when processor is
overheated with fan failed, and the overheat protection system would
immediately send out a signal to abort your system by cutting CPU
electricity before any damage is done. Unlike other manufacturers who use
BIOS or software to control the power supply of CPU, AOpen O.H.P.
Technology is purely hardware-controlled the minute after system boot-up,
and occupies no system resource. We are pleasant to phase in this
practical function on all AOpen AMD series motherboards to protect
customer's valuable hardware and personal data.
Note: AOpen Overhear Protection Technology only support processors
base on 0.13-micron technology in this motherboard.
