Quote: "Noctua makes great coolers, but as time goes on the older ones just won’t work with the new sockets that keep coming out. The coolers Noctua makes are excellent quality and perform well and they do come at a price, a higher price than most other out there, but they’re well worth it as you know if you’ve ever owned any. I have several of them and I recently decided to upgrade one of my kids computers with my old Core i5 setup and wanted to use a good cooler with it, and that meant I grabbed one of the unused Noctua ones that I had sitting around but I found it wouldn’t work with the socket 1156. Noctua has a solution for this though, the NM-I3 Mounting Kit that works with any of the new and old Noctua coolers so you can use them with newer sockets. The kit essentially makes them never become obsolete so that Noctua cooler you bought three years ago can still be used with the latest CPUs of today. The kit can be obtained free of charge actually from Noctua if you provide proof of purchase or it can be bought for only $10, which is well worth it I think to be able to use the older cooler with the newer platforms. So read on for a quick review of the NM-I3 kit…."
