I want to compare my temp with other macs to see if it is Normal.

Can you please download this Temperature Monitor Widget 2.1 - MacUpdate

and tell me what your CPU A Heatsink and CPU B Heatsink monitors as ?

For me

A: 70 C
B: 30 C

(celsius)

mkerr64 · Feb 15, 2007, 06:01 PM

WOW that high?
mines only

A Heatsink: 27 C
B Heatsink: 28 C

You can't compare temperatures if you don't state what activity you've been putting your processors through, both before and while you're probing the sensors for a reading.

Otherwise, what's there to compare?

i get that temp in idle state.

Mac Pros don't have die temperature sensors?

macgeek2005 · Feb 15, 2007, 09:30 PM

Cpu 1: 36
Cpu 2: 37

I use the program Temperature Monitor to check temperature. It's much better than any Widget.

Right now, for the 4 cores, it says:

1: 36
2: 37
3: 36
4: 35

I don't let my CPU's rest for months on end, and when the computers been sitting still for a while, they're at about 36/37C.

I think that any numbers lower than that are recorded shortly after the computer has been turned on, when the parts are still cold.

My MacPro has been on for at least 45 min surfing the web, I just took another reading:

CPU A: 21
CPU B: 22

Ambient Temp: 17

My bad for sleeping my Mac Pro when I'm not actually using it.....

kronos[pka] · Feb 16, 2007, 09:52 AM

i did a stress test today, Started up terminal, runned the "yes" command (apple's stress test prog)

and fired up World Of Warcraft, i played for about 30 min.

Cpu A heatsink: 122 C (not F)
Cpu B Heatsink: 25 C

my action? Called tech support again, they couldnt help me, called Customer Service, returned the mac, shipping it back now.

Im going to wait on the Octo-Mac before i buy a Mac again. (my 30" display is waiting on my desk for the octo mac till then)

I use the program Temperature Monitor to check temperature. It's much better than any Widget.

the widget is made by the same guys btw.

I seriously doubt that would make any difference. It should only matter what you were doing immediately prior to recording the temps.

kat81 · Feb 16, 2007, 11:58 AM

So, I have a 20" iMac G5 2.1GHz 1.5GB RAM
Running the program Temperature Monitor, since I don't have Dashboard enabled and don't use widgets, I get:

That all seems high to me, and esp shocking to see the incoming air temp so high. According to the thermostat I have next to me, my room is about 62ºF right now...and my comp is not in some corner/hutch where the air doesn't get in. So why am I running so hot?

My computer is always downloaded torrents, non-stop. When I leave it, I just turn off the monitor. If I have no downloads going, i'll put it to sleep when I leave for the day. The thing about sleep is the computer is always a tiny bit slower right after waking up, cause it's like turning the computer on. All the parts have settled down, and cooled.

The next time my computer has been off or in sleep for a while, i'll record the temperatures upon waking it up. Probably sometime tonight.

that is kinda hot, but then again, its an Imac, my friend got one of those, i will ask him what temp his is at.

I'm running a dual 1.8 G5 and the processors get up to about 135 degrees when the whole thing goes into thermal relief mode. I've had to put an external fan blowing into it to use the machine. I've run hardware checks aplenty and there's no answer I can find. The machine is clean.

MaxPower2k3 · Feb 17, 2007, 01:52 AM

Mostly idle, with only Safari/Adium/iTunes/Azureus/Mail/NewsFire open:
CPU Bay 1: 30º C
CPU Bay 2: 28º C
Ambient: 21º C
HD Bay 3: 25º C
Power Supply: 41º C

This, to appease Macgeek, is with an 18-day uptime (without sleeping the machine). Not that anything after the first hour or so (at most) of uptime really matters.

After exporting a 1080i EyeTV recording to a 1920x1080 H.264 file (about 80% of all 4 cores used) for 5 minutes:
CPU Bay 1: 37º C
CPU Bay 2: 39º C
Ambient: 21º C
HD Bay 3: 25º C
Power Supply: 43º C

Rolling Musubi · Feb 17, 2007, 06:19 AM

Following is at idle (2.66GHz with 5GB memory)

Following is running MPEG Streamclip (50GB HD transport stream to 1920x1080 H.264) for around 2.5 hours straight.

I do have the fans set to a higher speed though since with the default SMC settings, my core temperatures would be around 75C/165F and memory module temperatures near 82C/180F when doing things like encodes (fans never did increase under those heavy use scenarios).

booboo · Feb 17, 2007, 08:38 AM

Mac Pro 2.66

A: 26 C

P · Feb 17, 2007, 11:15 AM

For CPUs, it's usually best to keep the temperature at 60 C or below. You'd get less wear if you have it lower, but not significantly. Intel CPUs throttle when they get too hot, but the formula is a bit complex and takes into accoutnt the current load - I don't rememebr the details. Their own cooling setups blow at 100% at 60C however, so it's a good rule of thumb.

The Intel chipset and CPU isn't going to allow the CPU to get up to 122C; they'll underclock the CPU as necessary to keep the temperature below the safe operating temp (95ish C). I'd guess that whatever program you were using was just misunderstanding the signal from the temperature probe.

So anyway - what's the problem here? Does anyone have suggetions. I'm thinking I'm going to have to set up two additional fans inside the unit that just run full time.

dsteinman · Feb 22, 2007, 12:40 AM

Right now, only reading these posts, both cores 11 C, much higher munching on a DVD..

My temp is higher than yours, I get to stay home from school!

paulc · Feb 22, 2007, 08:48 AM

Hmmm, lots of differences here. Mine averages about 145/63 for each of 2 2.7G G5s CPUs. Fans run pretty quiet, bouncing between 300 (lower end) and about 700. Average is for "normal" kind of use, web browsing, e-mail, etc. Plus I have RC 64 challenge running.

tkmd · Feb 22, 2007, 10:14 AM

Ive got 91F (32C) and 95F (33C) for the heat sinks. I'm encoding a movie in the back round- I think that's pretty good!

Tenacious Dyl · Feb 24, 2007, 03:15 PM

For fun, my G5 Dual 2.0

Running with little load almost 24/7 for a few months, I have:

if you have that much of a difference, it might be A)one of your heatsinks isn't properly seated onto the processor, or B) the stress test is only stressing one processor, but it still shouldn't go up 100 deg if the heatsink is properly seated. or it's an erroneous reading by the program since the bios will automatically throttle the processor at whatever limit it's set to.

cmillerdesign · Apr 25, 2007, 03:56 PM

Dual 1.8 running all CS2 apps for 6 hrs (fans on, but quietly):

167ºF CPUA die temp
162ºF CPUB die temp

87ºF main logic board air inlet (yes, its stuffy in here today)

putting a room fan on the front of the air inlet:

135ºF CPUA Die temp
123ºF CPUB Die temp

77ºF main logic board air inlet (close to the room temp)

its no wonder this room gets so hot!

paulc · Apr 25, 2007, 04:11 PM

Wow, I did wonder if we had some air blowing into the machine from the front, would we get cooler running. As for "air inlet" it seems almost the entire front serves as air inlet for each of the zones...

"Main logic board air inlet" doesn't seem to be a reading Hardware Monitor reports, is this your own probe place right behind the cheese grater front?

122 C??? Sounds like a CPU that only exists as a molten puddle! Celsius thermal limit is about 83 C.

30ºF is quite a difference... but i don't care to sit next to a box fan on high either!

"Main logic board air inlet" is just a figure from the Temp Monitor app. I guess I could get out a meat thermometer to check the cheese grates. Temp outside is 76º, the window is wide open, and ceiling fan on.

This is pretty much doing nothing but browsing, listening to music, have had Photoshop CS3 running for about 72 hours with several documents open.

hempcamp · Apr 25, 2007, 07:57 PM

Temperature Monitor tells me that over the past 7 days:

CPU A was between 60.2 and 63.3º C
CPU B was between 59.7 and 62.6º C

Ambient Processor A between 50.5 and 50.5ºC
Ambient Processor B between 38.0 and 38.0ºC

(PowerMac Dual 1.8 Ghz)

G5 2.5 dual - betw.
176-178 f for cpu a

Probably high, probably will explode (again).

Nothing can fix that, those G5s run hot, hot hot!

bearcatrp · Apr 26, 2007, 03:59 PM

For intel macs, get smcFanControl 2.1.1 - MacUpdate . Its a fan utility to control your fan. I used it on a mini and worked great while running world community grid. Haven't tried it on my 2ghz mac pro yet thought. Here are my temps while running community grid:
All 4 cores: 185 F
Heat sink A: 98 F
Heat sink B: 102 F

Rolling Musubi, which program are you using to see such detailed results? Is that temperature monitor 4.1? I couldn't get that to run for some reason, it moved on the dock but never would open.
