Reconfiguring my PCs for summertime.

Yes, it's that time of year again, when temps rise outside due to good old Mr. Sunshine.

Anyways, I run my A/C all the time, from like May until Aug., but I really don't want it to fight with my overclocked (or non-overclocked, in the case of my i3-3240) PCs.

So while I've been crunching on my i3-3240 w/7790 1GB card (on two cores, BOINC NCPUS=2), I feel I should probably power-down my Q9300 rigs, at least until cooler weather hits.

So I have three computer desks, with cubby-holes for full-tower desktops (but not oversized full-tower cases, the Rosewill Blackhawk barely fits, and the front feet have to hang out over the front edge).

I've recently decided to build two 24" All-in-One PCs, using two 24" HDTVs I bought at BestBuy, with a pair of Foxconn NanoPCs I already had. Basically, I bolted them to the back of the monitor using the included VESA mounting hardware with the NanoPC.

But those have C-70 APUs, which really aren't any good for crunching. (Except perhaps, Correlizer?) They lack the GCN shader cores of my Kabini AIO, that was at least able to crunch Einstein@Home.

I probably should have spent more on a "real" 24" computer monitor, with HDMI / DVI / VGA, that way, I could have used the DVI port for a secondary PC. Sadly, my only options are HDMI and VGA, and the HDMI is taken up by the NanoPC, so I will have to use VGA to connect a secondary full-sized desktop.

I plan to put my two Q9300 rigs, into the cubbies, so that I can run them at the same time doing DC, or gaming (although that would mean I would have to run an audio cable into the monitor along with the VGA). Or leave them shut down during the hot months.

Edit: Oh yes, the 24" Westinghouse HDTVs that I picked up, list 25W power usage on BestBuy's site, but 40W on the mfg's specs. The AT-5570 NanoPC uses an average of 15W, according to a Newegg review, supposedly using a Kill-A-Watt. CoreTemp reports the TDP of the CPU in the NanoPC to be 8.2W.

My Q9400 is my main machine, but I don't crunch on it often in the summer, and I underclock/undervolt it to 2GHz@1.0V. It's amazing how much cooler it runs that way.

My Android tablet has been very good at crunching on very low power. It's around the same speed as one Q9400 core, but uses much less power.

My new laptop is crunching in the basement, which stays cool year-round.
 
Well not so hot here, but I shut off GPU crunching as it warms up (did so about a month ago), otherwise I keep CPU crunching until it get's really hot! (for here), about 30C.
As it approaches/exceeds that temp I 1st reduce CPU crunching to 2 cores, & then if need be shut it off at night (no AC here btw).

You can't duct any of the PCs heat outside?
