Figure I will toss in my 2 cents. I am currently running a FX-6300 with 8 gigs of ram on my unraid machine. It currently runs2 VMs. A Debian instance for all of my usenet stuff. (CP,SABnzb,sickrage,headphones etc..) and a Win server 2008R2 instance as a DC for my home. It also runs 2 dockers 1 plex and 1 OpenVPN and there is plenty of horse power to spare. I am also running a total of 10 disks. 7 storage spinners and 3 ssds in a cache pool for VMs and Dockers. I haven't noticed any heat issues but I upgraded my case fans to noctua NF-F12 fans to keep the case quiet. Checking my CPU temp now and its running at 25 C
