Installation is pretty simple for the ISGC-100 for both AMD and Intel installations. The Intel installation requires a little more work and will be the method we will be using. If you’re replacing the ISGC-100 with an old cooler, make sure to clean off the old thermal grease before applying the new one supplied with the ISGC-100.
The first step, after applying the thermal grease, is to attach the four rubber washers to the LGA775 clip. Then attach the clip with the screw threads facing away from the base; use two screws per clip to attach it to the base.
Since this is an LGA775 installation and the fan is horizontal, not vertical we can pretty much place the ISGC-100 in any position we want. The only problem is that it really only fit one way for me because it would be hitting something on my motherboard. This way was with the heatpipes facing towards the top of the motherboard.
Once you have found out which way works best for your motherboard attach it to your motherboard and flip it over. Then attach the four plastic washers and four nuts to secure it to the motherboard. Then flip it back over and attach the PWM fan cable.
The ISGC-100 takes up nearly no space in the case, so this gives you plenty of room for airflow or a perfect selection for a smaller case.
