Question about ambient temp with 15 x S9s

[cryptopeon]

I'm very new to the mining scene, ran 1 S9 in my 100sq/ft "server" room at my office for about a week got excited and bought 14 more.  My "server" room has the circuitry for the 220v connections as well as the bandwidth, what I underestimated is the heat.  1 S9 made no difference to the ambient temp, but I plugged in 5 today and wow the temp skyrocketed.  After 4 hours my chips had operating temps averaging 77 degrees but I'd say room ambient temp was around 30 degrees.  Tomorrow I plan to start up the other 10 units for the total of 15 running simultaneously.  I imagine the room temp will skyrocket to over 40 degrees.  The room has a medium sized A/C unit but other than that there is no ventilation whatsoever.  I'm getting the feeling that I've bitten off more than i can chew, will this be a problem or can these units survive in these temps?  Luckily I can easily make modification to the room and one of the walls goes directly to the outside so adding an exhaust fan is possible, I'd just rather not cut a hole in my building...

Unfortunately AC is not the way to go.  Miners are designed to use ambient air, and I've had my miners running when it was a bit hot out at 90+ degrees F and they were still running fine.  To run all your miners you'll need to figure out where you can put them and get outside air circulating through the mine.

exhausting the hot air is critical to having a successful mining setup. A/C will kill your profits, its all about removing the heat as fast as you can.

Save yourself the possibly burnt out boards, as they can be finicky as is.

I'm not sure what your overall building set up is. but you're going to have to put a hole in the wall no matter what to run all of them. Here's the kicker maybe 2 so that you can dusct intake air as well (don't forget the filter) for the miners and the existing equipment for the server room.

The plus side to making these modifications is that you probably won't need the AC at all, with the increased constant airflow through the room. Seeing as you like to jump in I would oversize the air exhaust and intake, just in case you want to go bigger.
