heat

Here in Canada, my Mac Pro acts as a furnace. I love it.

Either re-arrange your RAM so that the air flow is better (depending on how many full slots you have) or bump the fans.

Does your RAM have the huge heat-spreaders on it like official Apple RAM? I've seen RAM that works in a Mac Pro (3rd party obviously) that has crappy heat-spreaders on it that can lead to high temps. If you were folding on that machine, would it crash? How hot does the memory get in that use mode?

well all my ram slots are full. and yes, the all have the huge heat-spreaders.

it never crashed when folding, but i've now stopped folding on it anyway

This might be kind of off-topic, but how does your AC work when it's 48 outside? I'm just wondering because if you have it on for an extended period of time at that low of an outside temp, it's going to freeze. I'd probably open a window instead.

i might end up doing that if there's no other option. but you are right, i can't keep the air running all winter

Yes, computers (especially those under a heavy CPU load) can generate a ton of heat. There is a reason server rooms have their own climate control. If the room is too hot you have two choices:
1) Remove/vent the hot air to the outside (or to a larger interior space).
2) Add additional cooling to that room. If you need to add cold air while it is below 60 outside, consider adding an 'in room' unit.

A few other things to try:
Just run the fan on your climate control system. I do that during the winter to help circulate the hot air upstairs. One disadvantage of an 'open' floor plan is that in the winter once it get it 'just right' downstairs it can be unbearably warm upstairs.

Stop running unnecessary programs like 'folding at home' when heat is an issue. Running your CPU/GPU at full tilt like this increases the heat output.

Use a floor fan or two to circulate the air

thanks for the reply. i guess i might try some of these ideas. i think air flow is my main problem. i will just have to work on it.

Err, no it won't. The AC unit gets HOT when it's cooling the inside of the apartment.

Are you thinking of a heat-pump, which is essentially AC in reverse? Those will freeze in the winter (which is when you use them, of course) so they occasionally switch to AC mode to defrost themselves, and then heat the cold air it dumps into your house with resistive heating elements so the air is still hot.

Man I hate heat pumps. 😡

It is more likely to freeze as the input temp is colder. If the outside temp is 48F there is no need for AC, just fresh air. I'd get a cabinet for all that stuff and blow outside air into it. Put a thermostat to control the fan.

Agreed, that's by far the best solution. You know, I wonder why they don't sell refrigerators with that option...mine is against an outside wall and it gets pretty damn cold here (Illinois).

I know what you mean.my PowerMac G4 produces so much heat,I don't think the fans can keep up sometimes.😱

I had an MDD G4 powermac, that thing sounds like a damn jet. When I sold it for my Mac Pro, it was such a nice welcome. Especially with passive cooling on the video card.

Yep, according to Apple an MDD G4 produces more heat that an 2008 MP.

2008 Mac Pro: 1085 BTU/h with processors maxed
MDD G4: 1,228 BTU/h with processors maxed

why do ppl fold. i dont get it? you earn money on it?

it's a giant electronic pissing contest

The same reason people send their kids to school to learn proper English spelling and grammar, the betterment of mankind.

well my ram temps are still over 80 degrees celsius, and all the computer is doing is being a web server. what could i possibly do to try and reduce the heat?

 

[IronFixXxeR]

If its that cold outside having the A/C on really is ridiculous. Open a window! It can't be raining ALL the time, right? I love this time of year when I can open the window and have a computer or two acting as a personal heater.

On that note, I used to run seti@home on my mac pro and it would heat up my small room in no time. I find the energy it uses and extra heat it makes not worth it.

How much is your electric bill? XD

 

[twoodcc]

Without the computer doing anything but being a web server, the temps are still high.

On a side note, my last electic bill was $149

 

[twoodcc]

surely someone can help me out? 80 degrees Celsius can't be right while the computer is doing nothing (but being a web server)

 

[twoodcc]

ok, today i shut down the mac pro, took out all the ram and hard drives, and went to town with some compressed air. tried to get all the dust out and i even took each ram module off the ram banks.

now, after putting all back together, here are my temps and rising:

I just keep my windows open. Keeps the heat down from 2 dedicated folders running in addition to the Mac Pro.
