A bit confusing when you first open the box, there are so many different bits and no instructions at all but a quick look on you tube at the different brackets and it can soon be worked out, took me about 15 minutes to fit (that was looking on youtube as well), with the hyper 212 evo up and running it has cooled my Ryzen 5 3600 down from 87C and rising (using cinebench 23 and the amd cooler) to 64.6C max running the same program, I'm well impressed. I bought 2 of these brackets as I have 2 hyper 212 evo's, both machines are now running much cooler (20 degees C +)
I bought this kit to to replace the old mounting bracket for my 212 evo as I bought a ryzen 3600, and it is possibly the worst designed mounting mechanism I've seen so far. I couldn't even get it screwed on. Came with no instructions either.
If you have a 212 evo and are considering getting this kit, seriously don't waste your money and just get a different cooler.
