7. Insert into the AGP slot the graphics card with the VGA Heatpipes installed and move the VGA Heatpipes
around until they properly fit the grooves of the VGA Case Block Base. If the VGA Case Block and VGA
Heatpipe do not fit well, either disassemble the VGA Block Base and move it, or modify the VGA
Heatpipe’s shape slightly and determine where the VGA Block Base will be located in regards to the Right
Heatsink Plate.
Note)
1) The graphics card will be reinstalled once more, so the card should not yet be fixed to the Card Fix Bar
using the Card Fix Bolts.
2) There are many types of graphics cards. Thus, the VGA heatpipes may not fit well in the grooves on
the Case Block Base. In this case, the user needs to reshape the heatpipes to better fit the grooves.
3) If the VGA Heatpipes for the VGA Cooler bend below the Datum Line, the heatpipes will not function
properly and the GPU (VPU) may become damaged. Check if this is the case before proceeding.
