Is it normal for the voltage to oscillate in between around .05 V during normal operation? Why would it do that?
Slightly unrelated, but what are SYSTIN, CPUTIN and AUXTIN on the temperature reporting tool?

The only good reason for a voltage to be jumping around would be if your processor has some sort of power saving operations.
What temperature tool are you using? I'd like to know what the values on those are... it'd help me guess what each represents. Generally, though... anything SYS would be your northbridge, CPU would obviously be your processor, and AUX would be referring to temperature readings on your PCIe sockets. You may have AUX0, AUX1, AUX2, etc labels. At least this is the case on any temperature tool that used these labels.
It's worth noting that if CPUTIN is a temperature, then it would be a reading closer to the temperature of the IHS and not the reading of the cores themselves. Those should be listed seperately as Core0, Core1, etc...
I'm using the CPUID tools (http://www.cpuid.com/hwmonitor.php).
Below is a screenshot. The actual variance is low there. But it usually ends up in .05 V. Haven't seen it any higher than that.
I'm not getting discrete AUX readings, but then and again I only have one slot occupied... The high AUX temperature then makes sense, considering that's where the graphics card is sitting... Good to know these things :)

It's strange to see your core temps lower than that CPUTIN row. The variance between the AUXTIN and the GPU core make me doubt they're related, as well. However, the data I'm questioning is the one on the GPU Core row as those are extremely high if you're just sitting there on your desktop. The AUXTIN looks like a more accurate number even for the passively cooled model.
I mean... when I download the tool, everything looks about right. To the point that I would say the CPUTIN is in fact the temp around the IHS... but I still find it abnormal that your cores have a lower temp than the IHS by a fairly significant amount. I should also mention that my AUXTIN is reading at 127 °C, which is clearly out of whack, so I have no idea what it's reading.
Heh, anyway... I'd like to post a pic of mine but the temps are embarrassing with the heatwave we've been having in New York and the fact that my air conditioner is broke. I'm thinking I will put the processor back at stock clocks until it cools down. Anyway, the variance in the voltage isn't that bad. I couldn't say for sure but I think .05v is acceptable. I'd watch it if it goes more than that, though.
Well, it only hit the high 50's here in Portland today. People have been walking around wearing coats and gloves. Maybe we can try to split the difference somehow :)Quote:

I would say that 50mV (0.05V) variation in the voltage in is perfectly normal. The 3.3V power comes directly from the PSU, and it's known to not be entirely stable. The one you don't want to vary too much is the CPU VCore - at least not unless you have set up the system to do frequency/voltage changing based on load.
There is no telling what the temperature sensors are actually connected to - it's up to the individual motherboard vendor to use those sensors as they see fit - and the one saying CPU may well be a sensor somewhere near the CPU - it is obviously not the CPU core itself, because that's reported separately elsewhere. An AUXTIN of 127'C would indicate that it's a "not connected" input on the temperature sensor chip.

Ah, ok. Excellent.
The CPU VCore is exactly the one I'm looking and reporting a 0.5 V variance (despite being lower on that particular screenshot).
Meanwhile, the GPU is indeed high. This relates to a recent thread here on the Geforce 7300. Basically the card is fanless and NVidia assured me (along with you folks) that's an acceptable temperature, being only 120c a worrisome number as Elysia mentioned.
I'll try and check other reporting tools and compare results, nonetheless.
Over her in Portugal, spring is coming late, it's coming fast and it's coming furious. Temperatures are already on the 29c (84f) mark, having raised from 16c (61f) just last week. Until the week ends we are expected a consistent 35c (95f). An this is not even summer yet. This is going to be a bad year for my heating concerns.
Is it varying more than 50mV from the median value, or is it 50mV from peak to peak. The latter is well within the margins, the former just about OK [at least in AMD's processors, and I would expect that Intel specs are similar if not the same].

Good question. And you just reassured me. It's varying ~0.2 V from the median, being 0.5 the amplitude of the variation. Guess no worries then.Quote:

Idle? No, no that's not even close to true. I think maybe you meant the physically acceptable temps for the cards. However, even at load you shouldn't exceed 80 °C on any graphics card. You really want to try to keep it under 70°C even. I don't know where you got your information, but please let's not try to spread it around and confuse people.Quote:

There is a big difference between what a GPU can withstand and what is safe for it. I think all of these GPUs have a physical threshold of 130 °C, but you really don't want to go anywhere near that. If you keep letting it hover around where it is, you're surely going to be replacing it much sooner than you'd ever imagine. Really, the only reason you should be exceeding that 80 °C temperature on your normal card is if it's being overclocked. Then, I would say keep it below that 100 °C point.
No, I meant celcius, and it's not misinformation. Mario got the answer from nVidia itself. The fanless card is OK at 100 °C.
I didn't quote Mario's statement about nVidia claiming that to be an acceptable temperature for the fanless card (even though, I'm quite sure they didn't intend that to mean an idle temperature). I quoted your statement about being equal to above 100 °C on idle as normal for newer nVidia cards. That is an absurd statement and if you really wanted to email nVidia, they would agree with that.
The fact is, all nVidia cards will start to throttle at 110 °C, so if it's going to hover around 100 °C at anything but peak load, then when you do reach peak load, you're only going to get reduced performance. Anyway, the temperature that the original picture Mario posted is showing a temperature about 15 °C above what a fanned 7 series card would show. For a fanless, I suppose this is acceptable, but those cards are never designed to reach a peak load and I would be careful if you intend to do anything that would put that much stress on it.
Where did I mention it's normal for it to be 100 or above?
I mentioned 100 or below is normal.
Yes, my own card is 65 degrees at idle.
No, no... I phrased that poorly. When you say <= 100 °C, you lead people to believe that you are referring to temperatures at 100° or close to just below it (like high 90°s), not 65°. If you're telling us it will hover around those temps, then any extra load would put it above those temperatures. If you actually look at my sentence, it is missing a word, that you filled in to be "or" (as the <= would be), but in fact it was meant to be "and" meaning hovering at the 100°C point and potentially getting higher under more stressful circumstances.
Anyway... since the release of the 7 series, I've owned or built computers for others using about 10 nVidia cards. All of which I checked temperatures on. These cards would be 7300LE, 7600GT, 7800GTX, 7950GX2, 8500GT, 8600GT, 8800GT, 8800GTX, 8800GTS 512mb, 8800GS, 9600GT. Of these cards, with an ambient temperature of about 25°C, they never would reach an idle temperature above 55°C. So, if you want personal data and experience to count for anything, there is about 10x as much experience as you have just provided. Personally, I think however, that any personal experience is rubbish and would rather get my data from reviewers with controlled testing labs.
Ah, alright.
Apparently, the fanless card can hover around 100 degrees if under load and it's perfectly normal for that kind of card, but for the fan-y cards, 55-65 degrees idle is probably a better bet and well... I don't know about load since I haven't really looked.
I won't doubt that there are fanless models of nVidia cards that reach those temperatures under load, but I could in no way recommend them. At those temperatures, you are easily cutting your processors life expectancy in half.Quote:

Oh, beautifully. The leap was gigantic from the old PIII. I could notice it instantly. My project which took around 3 minutes to build with pre-compiled headers, now takes just around 15 seconds. You can imagine my face when I first built with the new puter ;)Quote:

But I worry too. My wife is not too happy of me making this a secondary machine once the laptop arrives (next week!!). She rightfully argues "it cost money and you'd better use it!". So I'm considering possibly going nuts by December and keep the case which I do like very much and do a major upgrade in order to make this my main machine.
With 3 GB of memory, there will be little paging regardless of how many programs you have active!
I currently have only 54 processes running, including Visual Studio and Firefox, but I used to use far more, plus I use all visual effects (and I can even use WindowBlinds) and services and get no paging.
No, sir, you will get a long way with those 3 GB :)
> I currently have only 54 processes running
Only!? I have 16 on my windows install...
BTW, what card do you have Elysia? You keep talking about how warm it is, yet you haven't said what it is? I've never seen my fanless cards go over 55C (under load for a few hours too [too many games ;)] -- 6600TDH & 8600GT with really fat stock heatsinks), and where I live it can get rather warm (around 42C shade temp). Fanless all the way baby :)
I don't have very good air flow IMO, and my cards have never been that warm at idle (5200FX, 6600TDH, 7600GT & 8600GT) with an ambient temp of 27C and my computer is on most of the time. Which brings me to the question, how accurate are the sensors?Quote:

I would say significantly more accurate than whatever sensors you are using, because if you're at the same ambient temperature I suggested, then to tell us that your fanless graphics card hovers only two degrees Celsius above ambient room temperature on idle is more ridiculous than hearing cards go above 100°C on anything but full load. Given the lack of air a GPU gets, I'd be surprised to hear that the processor is any closer than that to ambient with the computer turned off.Quote:

At 27C ambient, I've never seen them hit above 55C under load (idle around 38-40C).
Oh, I apologize. I misread your ambient temp to be your idle temperature. Idling at 40 is pretty good and expected for an entry-level card. The higher idle temps from the list above came from the high-end models like the 7950GX2 and the 8800GTX. Currently my 8800GTS is running idle at 44 °C with a case temperature of 33 °C. Keeping in mind, however, that it is not using a stock cooler.Quote:

Wow... what manufacturer? From my experience the 9600GT cards run exceptionally cool compared to other models. Just look at the one referenced in the picture of the HWMonitor download page. Considering the processor temps, I'd say the guy isn't water cooling. Though looking at the PSU and HDD temps, it's clear that they're running at an extremely low ambient temperature.Quote:

No, looking at that, I'd definetely say that individual is using good airflow and/or watercooling, because I cannot even attempt to get HD temps that low (they are typically in 50-60 range). My CPU range is 35 - 50, depending on load, I think. It helps to have a side fan blowing cold air directly over the processor.
As of now, my two HDDs are running at 44°C and 46°C. That's again, with the ambient temperature at 33°C. Generally, they run below 40° on a normal day and that's without a front intake fan pulling air through them. With an intake fan in place, they should on a light load run in the high 30°s. Everything on that list is running at about 10°C below what it should be, with the exception of the processor which I imagine is severely overclocked, explaining the high temps. The 9600GT I installed was running mid-30s at idle, but that was with a slightly better cooler. I'd expect from a good manufacturer that the stock cooler should leave you with idle temps around the low 40s on that card.Quote:

Basically the GPU increased two degrees Celsius (35 Fahrenheit). Despite Nvidia tech support reassurance, it just seems almost careless to allow my GPU to sit at that temp in idle mode. Besides its contributing to the overall temp inside the case in unhealthy ways.
EDIT: My HDD instead, is surprisingly low all things considered. It's running at 40c (103f) after a night and a morning of labor with torrents
Have a look at the temps now, I can see they're pretty low. I can only guess they rise in temperature as it gets hotter inside the case and as they are powered on a for a while (I just booted the computer!).
HD temps are 27, 24, 27, 25.
CPU is 29.
GPU is 41.
For now, at least.
