As the heat has its grip on the Northeast, I've had to shut down the crunchers so that they do not come down with heat exhaustion. My apologies to my wingmen/ladies. Today will be the 3rd day in the high 90s, making it offical. When machine temps remain in the high 70s, crunching will cease until ambient temps come down to the mid- 80s. Rain is forecasted for this afternoon, hope it happens. Yesterday the offical was 97, but at my house it hit 102.

I hear that. Here in south joisie we has 100.2 for Wednesday and 99.8 for Thursday.
As the sun beats down on my condo from 3PM until it sets. I gets loads of heat. So much that my ancient central air can't really keep up. Like yesterday when it ran continuously from 11AM until 9:15PM with it set for 78ºF. It actually got up to 82ºF inside my place.

I think I can top Y'all, yesterday it was 106F outside and 78F inside, If I'd closed 2 windows like they are now it would've most likely been somewhere between 74F and 76F...

Oh and the OP is forgiven...

Try to use Tthrottle. See: http://efmer.eu/boinc/
You can set the temp you want.
You crunch less but you crunch.

I have 4.5 tons to keep me cool. I lived in the Texas desert when I was in the USAF at Sheppard AFB the temps run high there but the humidity is low so the heat is not as bad as 100 degrees in the southeast where it is hot but also very humid which is more intense heat due to the humidity. I had some west coast friends and they said the humidity they compared walking in the humidity to swimming.

My temps usually run in the 70's no problem on hardware.

A few summers ago my ac went out for a few weeks and it got 106 inside my home daily until ac was fixed and my cruncher suffered no ill effect it kept on crunching no problem.

Here are my temps on my cruncher now, keeps on crunching going on about 3 years now with these temps. My video cards use to run hotter in the 90's but I moved the 2nd card from the 2nd slot to the 3rd video slot on my mobo and the video temps dropped to what they are now. In the spring the temps were about 5 degrees cooler.

I decrease the % of CPUs to keep the temps under control. At the moment of shutdown today it was set at 50% on both machines (4 cores + 4 GPUs). The GPU fans are at 100%. At 50%, temps were in the mid 70s; which is where it normally is at 90% CPU usage.

Ah, the memories of Sheppard in the summertime, but that was probably before your time on this earth. But it still wasn't as bad as Keesler in Mississippi or England in Louisana.

As a fellow Northeasterner, I can second this ridiculous heat. today is the first day under 90 in a few days here, and it's still in the 80's. I prefer 60-70f and partly cloudy, personally.

The AC has been keeping my ambient temps in good standing, however I did stop running seti on my server for the time being to help keep the air as cool as possible.

I can say that living in a desert has it's pluses, one is low humidity, then that means one can use a swamp cooler to cool the house with, some out here even have one above the garage too, but then coolers are fairly cheap to run, even 24/7. In humid areas one needs different cooling I guess.

It was 1981 and in the fall I remember during the morning fall in while we were forming it up there would be ice in the parking lot very hot in the summer and very cold in the winter very unusual weather. Did you remember the tornado that was 5 miles big and I saw pictures of the destruction.

Waaaaaaaay after my time there, '63. By the time you got there I had already been off the force for 12 years, after spending 2 years 6 months and 27 days (3 tours) of hell in a small country called Nam Viet. You know it as Vietnam.

My family moved there about 6 months after the Tornado wiped out the south side of town. The funny thinng about the Wichita Falls area is that it gets 30-40 inches of rain a year. It doesn't qualify as a desert

I never saw any rain just tall brown grass cracked dirt with ant trails small bushes called trees and lots of cactus and jack rabbits. I would definitely call it not a lush wooded country side resembling a jungle as such a place should be with that much rain. In town people had trees but short and green lawns. Outside of town it was different the trees were squat little shrubs and the grass was tall and dead with jackrabbits and cactus. Maybe not a true desert of sand dunes but definitely a lush green wooded land full of shade trees and lush foliage it’s not.

Remember that you can tell BOINC to only process between certain hours. I do that mostly because of my Time of Use electric rates, but the high rates also coincide with highest daily temperatures.

As another poster mentioned Tthrottle works really well at controlling internal temperatures. When it's hot, Tthrottle throttles more. When it's cooler, it throttles less.

TXU is offering free Electricity overnight. I'd say ramp up the rigs and AC at night then turn it down again during the day.

BTW I'm an avid bicycle rider and always ride the texas heat. call me crazy but it is a nice challenge

Yeah, even though I spent eight years in Peoria and remember summer temps mostly in the 80s as a kid, living in Mississippi, just to the east of the Louisiana swamps, it's always 90+ degrees here for some part of the summer with outrageous humidity.

On the rare occasion we get out of here for the summer, and we're flying, when the plane starts mixing the ambient air on arrival sometimes there is an audible "ugh" from the passengers. When it is at its worst it is like trying to draw a breath from a running garden hose.

I've got 6.0 tons of ac on my house and in the worst of it, you can't keep the temps under 82 inside and the ac condensation drains run like someone left the tap on. The units might cycle on and off from eleven or midnight until six or seven in the morning, but sometimes they just run.

I've wondered if you were to take all the condensation off of all the air conditioners in this area and combined them, how much water you'd be talking about.

Enough to irrigate some land, or at least keep the lawn from dying, I'd bet.
