TYAN TRINITY I845 User Manual page 20

There are two beveled corners on the CPU, which will match the two angled corners on the
socket. Careful install the CPU by lining both Pin 1 on the CPU and Pin 1 on the socket, making
sure the pins actually fit into the socket. Do not force the CPU into the socket: check the pin
alignment of the CPU pins to socket holes.
Push down lightly on the CPU while lowering the arm on the socket to secure the CPU (see right).
A squeaking noise may be heard while lowering the arm or the socket may make a 'click' noise
when the arm is locked into position: these noises are normal.
Installing the Cooling Fans
After a CPU has been installed, you will need to install the proper cooling device for the CPU. This
device, a heatsink/fan combination can be purchased at many computer retail stores. Installation
of the cooling device may vary depending on the fan manufacturer's design. You should also take
space into consideration when installing a cooling device: make sure the cooling device is not too
big, or else you may end up damaging components around the CPU socket.
The Trinity i845 ships with a special Heatsink retention bracket with four prongs that plug
directly into the four holes around the CPU socket. Once the bracket fully inserted, press
down the white into the bracket to fully secure the bracket onto the board. Then you may
proceed to installing the heatsink/fan.
Tyan highly recommends that you use a thin
layer of some type of thermal compound
(available from many computer retail stores),
between the CPU and the heatsink, to
maximize distribution of heat away from the
CPU. Please use extra caution when installing
any type of clamp-style fan, or else damage
may occur to the CPU socket and or the CPU
itself.
The FAN connector has a 12V, 0.3A limitation. Tyan takes no responsibility and will
