I have several systems with a Gigabyte Chassis that I'm giving away to my mom and my sister. I have a couple xigmatek dark knight II SD1283 Heatsink Fan solutions lying around. They WILL install in the gigabyte chassis on the motherboard, but they are too tall to get the case lid back on. They stick out of the case about roughly an inch when installed. Does anyone know a heat sink that is good that might be an inch or 2 shorter?
