I had a request to put these up for auction since I have a parts bin full of them.
These are used between de-lidded proceesors and their heat sync conterparts as protective spacers so the positioning of the heat sync is calabrated to the exact hieght required.
NOT to be used for standard lidded XEON processors found in 2009 Mac Pro Single procssor machines and 2010, 2012 Mac Pro Singal AND Dual processor machines which use hinge style processor mounts.
Sold in pairs.
