I saw a really interesting post over on SFF and it game me some inspiration for a build that's been hanging around for a while. I dropped this on as a reply but thought I would post here if anyone was interested. The base I used: NF-A92X14 @1400 RPM plus a 12mm thick heatsinkoff ebay With a bit of trimming and a couple added holes, this gives a 1.5 slot (~30mm) thick, extra short card (15cm) that's almost silent. At the moment I am getting 65c stable after an hour of Furmark, 25c while browsing. Ambient is 20c.
