Hot weather - the enemy of distributed computing

It was 80F here today, and my CPU temps were like 83C, and GPU temps 77C (not overclocked). Too hot. Too bad it's only spring.

So until further notice, I have to shut down F@H. Sorry Team.

(Can't really afford to run the AC yet, but if I can get the money, I'm going to upgrade my cases to Antec 100 cases, and put in quite a few fans. Part of the problem with my temps are my CoolerMaster Elite 330 cases, which only have a rear exhaust fan, which doesn't do much.)
 
I hear ya on that one. With summer rapidly approaching, I'll have to temporarily stop my efforts with Rosetta@home. While I kinda get "free" electricity by living at home, the electrical bill will too expensive for me to continue.

Which is why I've also been racing to get to 1 million credits, before I shut down, so I can look forward to a new project in the fall.
 
Still cool enough to run my gpu rig here but as soon as the weather gets warm, I too will have to shut down. Will have to rely on CPU folding as it's not nearly as hot.
 
Well, you could all move ... for example to northern Sweden: clear sky, -2.6ºC = 27.3ºF. All comps going strong. No need for AC yet - the heat from the computers is needed for warming the house and providing hot water ...

yeah... i don't think my (virtual) gf would like that too much..

I've had to stop DC on any computer that isn't WC for the cpu... I've had cpu temps get up to 97C while doing aqua (i7-860)...
 
same here...temps are around low 80s here in central FL.
My production will drop during the summer...I will set crunching on a schedule and only crunch at night... 🙁

still better than nothing - 🙂
 
I am down to 3 1/2 boxes... Electric bill. I am buying a second house as a rental, and I can;t afford the $300 bills anymore.

The 1/2 is because my Sandybridge won;t finish a bigadv unit, so its only running gpu;s

i'm in Sarasota, FL. however, i live in an igloo...well not really, but i just can't stand it when my condo gets much above ~70°F, so i always have the A/C on. on that note, i suspect my productivity should be approx. the same year 'round.
 
London's just had a heat wave with peak daytime temperatures of almost 70°F! The parks were full of people and everyone ate their lunch outside in celebration of the sky-rocketing temperature.

I've generously decided to keep running F@H throughout 😉

well hello Sarasotan...I live there too.
I dislike A/C, or the heater, so I try to avoid these when possible.

Now that is a tempting idea. I've contemplated moving farther North to get away from the incoming summer months.

Too bad such a move would be expensive.
 
Minnesotas nice! temps are still pretty cool. And I am in the process of moving a bit to the north, closer to the cities. Still, moving just plain sucks!

When I had a house in Georgia I kept a farm of computers in the attic (as witnessed by other DC guys in here) so I don't understand all these posts that heat causing fleets to be shut down.
 
When you had a house in Georgia, CPUs didn't put out enough heat to need heat sinks like this!

More importantly, DC couldn't use four of these along with the CPU!

Basically, power requirements for a dedicated DCer have gone up, so heat output has as well.
 
Well, the weather was a little bit cooler, so I started the GPU F@H again for the moment. But if I run GPU+CPU together, the CPU gets way too hot. So no CPU F@H.
 
Have you tried underclocking and undervolting your CPU? Lower voltage especially can work wonders on heat.

Four of those in one rig?

You would need a 3000w power supply and dedicated 30 amp breaker

Is there such a thing as a 3000w PS now?

90 C is still 90 C

If they shut down due to heat it would be more of a air flow issue because of the cramped quarters rather than just heat itself. Being so close causing thermal runaway.

actually under load (but not overclocked) the GTX 590 consumes a bit over 500W, so unless the rest of the system consumes an additional 1000W, you really wouldn't need a 3000W PS. secondly, there are still several GPUs out there that aren't dual core CPU's, and as such, they consume far less power and produce far less heat. nevertheless, the fact that there exist mobo's w/ 4 to 5 PCIe x16 slots (even if they don't all run at full x16 bandwidth when all are being used) does in fact mean that 4 GPUs can be used concurrently in a single rig.

i see your point, but it doesn't change any of what Ken G6 said. the bottom line is that DC rigs consume far more power nowadays than they did when you had a crunching farm in a southern attic. and as such, they produce much more heat. if that heat isn't dissipated well enough, machines start to overheat. if you DO dissipate that heat sufficiently enough, you'll sure as hell notice it in the form of increased ambient temps around the house/attic/whatever. the higher the initial ambient temp is (that is, the ambient temp caused by the heat of springtime or summertime), the less efficient your CPU and GPU cooling devices will work. at some point, some folks are going to see that, b/c of seasonal temperature changes, their CPU and/or GPU temps are no longer staying below a certain limit. when that happens, they decide to shut down their crunching rigs for fear of damaging parts by running them at dangerously high temps.

It consumes far less than 500W, actually close to 300W under normal load according to the reviews I've read, but with 4 in a system you would probably want 2 PSUs since 1500W wouldn't cut it.
 
I didn't really want to, because it costs $$$, but I turned on my AC, set to energy saver and 70F. It dropped my GPU temps from 79-80 down to 70-72C. Still too warm to run my CPU folding at the same time, I do need a pair of new cases.

Now I'm paying double for Folding, the power for the computer, and the power for the AC.
 
Its nearly 90 here today.

Half of my machines are in the coldest darkest room in the house and they are all reporting acceptable temps and the ambient in there is quite pleasant.

The other half of my machines are in my room. With 2 box fans sucking hot air out of the room and sucking cold air from the rest of the house into the room, the hardware is maintaining good temps. The ambient is borderline too warm.

Good news is, today is a bit of a fluke. Summers here are usually not too bad, low 80s, high 70s, with cold nights. I should be able to maintain all my DC work, except for on the hottest days of the summer.
