So Ryzen CPUs have been available at retail for a month now, but there are still coolers out in the wild that don't have AM4-compatible mounting hardware. I figured I'd share my experience with three companies, since I own coolers from each and I figured I might as well get all the free AM4 brackets I can get my hands on, "just in case". If you've had to get AM4 mounting hardware, I'd be interested in hearing about your experiences.
I have a PH-TC14PE that lived in the Ivy Bridge system that my Ryzen rig replaced. Since that rig was going back to stock clocks to be given to my dad, I put a CM Hyper 212 Evo back in it and it's fine. At any rate, the cooler is in its box in my closet, but I had the Amazon invoice and Phanteks offers a free bracket if you email their support address. I sent the email on Friday with the invoices for my motherboard, CPU, and cooler. I got a response on Monday that a bracket had been shipped out. It arrived at my door in central Illinois today from California. The bracket arrived in a cardboard envelope about a half hour ago. It had insufficient postage, however, so the mail man knocked on the door and set off my dog while I was on a conference call. My wife happened to be off work and paid the $1.55 in extra postage. This isn't the cooler I wanted to put in the Ryzen rig, but it's the one I have the hardware for, so I can now do that.
I have a Kraken X31 that lives in my wife's i5-4690K PC. I got it in September. There's a page on NZXT's website where you can again send the invoices for your CPU/mobo/cooler and they will mail you a bracket, eventually. The company got back with me right away to tell me that there was an issue with getting brackets from Asetek, which actually builds the Kraken line. I was assured it would ship after 3/15, though. Last week I got an email thanking me for my patience and they were expecting the hardware to ship "early next week" (so this week) and that I would receive tracking information when it shipped. So far, that hasn't happened, but we'll see. This is the reason I've been using the Wraith Spire since I built my system, but I've gotten impatient with Asetek so that's why I got the Phanteks bracket.
My Skylake box has an H75. This is also made by Asetek, so theoretically it has the same production issues as NZXT. However, I haven't been able to even order the bracket. The promo code that Corsair has posted on its website
doesn't work for me, and I'm not going to pay for it. The code was not valid the day I ordered my CPU and motherboard on March 3, and it's still not valid today. Regardless, the hardware is still in "pre-order" status on Corsair's webshop so it's apparently not ready yet.
It's not fair to malign NZXT or Corsair here. So don't think I'm doing that. Instead, the problem lies (apparently) with Asetek getting the mounting hardware stamped and shipped. Although it's fair to say that Corsair should fix their dang shop.
The lesson here, of course, is to not re-use coolers with Ryzen. Buy something compatible along with it. If you want to go closed-loop, there are select models available from Cooler Master and Corsair that should work. If you want to go with a big tower, I was happy with my Phanteks experience, although I haven't actually installed it yet.
