This heatsink is specifically designed for the LSI 9201-8i 9211-8i 9200-8e 9220-8i 9240-8i 9212-4i4e and is an essential component for optimal performance. Made of aluminum with plastic pins to attach to the LSI 9201-8i 9211-8i 9200-8e 9220-8i 9240-8i 9212-4i4e.
These are salvaged from defective LSI 9201-8i 9211-8i 9200-8e 9220-8i 9240-8i 9212-4i4ecards and may have residual thermal paste or epoxy on them. Sorry, I don't have the time or resources to clean these, but want to let you know what to expect.
If you've damaged your heatsink, or perhaps just want a spare for experimenting, these are it!
