Went to my local Fry's today to pick up an AM4 heatsink to finish up a build. Was hoping to pick up another 212 Evo, but they didn't sell them there or at least I didn't seem them. Noticed they had the Enermax ETS-N31 for $5 after rebate. I've only ever tried Enermax's fans before and i wasn't too impressed, but after looking up reviews on the ETS-N31, which seem to be mostly positive, I thought I'd give it a try for $5.
There seems to be free shipping but the item is on back order. Best bet is doing local pick up.
Bellow is the Enermax product page.
