"It is nice to see that a heatsink manufacturer sticks behind their product. Performance heatsinks are usually a sizable expense and to have to purchase another heatsink just because you upgraded your system can be frustrating.

As I mentioned earlier in the review, Noctua does have an LGA1366 Mounting Kit and it is still available online or via Noctua, although it has been discontinued since the launch of the NM-I3.

If you do happen to own one of the listed Noctua heatsinks (listed in specifications) you would be doing yourself a great injustice if you didn't take advantage of Noctua's free offer. Performance cooling comes at a price. If you can extend the life of your heatsink and continue to benefit from that cooling performance without having to upgrade each time you build a new system, the price suddenly doesn't seem bad at all."
