View Full Version : How hot are you...
How hot is ur cpu on idle and load
19c idle and 25c load here :)
IF i left my non overclocked, then 19 idle and 21 load.
Gaming pc idles around 35ish full load around 60ish. This is a quad 6600 @ my every day speed of 3.6ghz with 1.5ish v on the cores. Stock dunno as it was only at stock for long enough for it to boot into the bios ;)
IF i left my non overclocked, then 19 idle and 21 load.
The temp only rises by 2c under full load?? You sure?
Waht temps do you get with the overclock.
On my Watercooling, a E4500 with 1.2v stock will be ambient temperatures if not a few degrees more under load.
he has the advantage of watercooling :(
Free Watercooling i might add :P
Next question what are you monitoring the temps with, NOI but those temps just seem a little "too" good.
I measure with Coretemp. Honestly, the only real heat in the case is from the CPU, as the Northbridge is actively cooled. Need a screenie?
Nope if thats from coretemp then i believe you. But you must live in a fridge then mate :lol: cos i was under the impression the 4000 series ran quite warm. My 4300 seems to anyway in my media pc but that is under a rather small watercooling setup (dual 80mm rad) also running 1.3v for the 2.7ghz overclock. Again no idea what it would be like @ stock.
Do you have the thing enabled (sorry can't remember what its called atm) that lowers the multi and core voltage enabled?
I'd be weary of those idle and load temps Mike. Unless your ambient temperature is well below 10c (baring in mind your case can't be colder than ambient) those temperatures seem quite off the mark. Reasons why those temps might be wrong are
- You're reading temperatures from the socket rather than the DTS under the CPU's heatspreader
- The application you're using (assuming Intel setup) has picked up the wrong Tjunction and your temperatures are 10-15c lower than they should be as a result
- In some instances, with lower readouts from the DTS sensor, it may diverge from an otherwise linear temperature line resulting in the temperature being read a lot lower than expected.
So yeah, as above what's your CPU and what are you using to detect the temperatures? Not having a go at all, I'm just trying to explain why everyone thinks it's a bit off :)
-----
At present at 32/35*c idle
load with two instances of folding@home is 42/45*c on each core respectively.
Delta T of about 10. Not too shabby :)
My E4500 runs cool at stock, but needs a lot of voltage to reach 3.3ghz, and that gives it the high 40's temperatures that i get when im not at stock, yes i do use Speedstep :)
I used to run speedstep, though it doesn't really do too much for me when I have a 7x Multi CPU. 7x Multi Constant + Undervolt here.
To be honest voltage from 1.36down to 1.1-2 is a lot when overclocked, same with going from 3.3ghz down to errrm whatever it is. Of course I dont think speedstep really matters at stock due to low power consumption.
if i run mine on stock speeds but low power im as cool as a big long green vegtable

but when im at 3.2ghz and slightly overclocked and my cpu has no active fan http://img179.imageshack.us/img179/3105/orthospassiveub5.png
i can get a bit warm :)
Using everset to read from the cores, my hottest core in the Q6600 is 38 idle and 49 load.
That's with passive H2O cooling - so I sacrifice low idle temperatures for silence.
The Q6600 also runs at 3.0GHz at stock voltages...

What's you're VID and stepping ?
Problem with peedstep and overclocked systems is it only knocks the multi down not the fsb so can cause all sorts of problems. Hence i never use it.

Load

Idle i do not know, as im always running FAH...
but when im just pottering about on deskytop (30% cpu usage solid) then these are my coretemps:
Core #0 = 40 Deg C
Core #1 = 42 Deg C
Core #2 = 34 Deg C
Core #3 = 32 Deg C
Under load i get roughly..
Core #0 = 52 Deg C
Core #1 = 50 Deg C
Core #2 = 45 Deg C
Core #3 = 45 Deg C
but i havent really stressed it that much, nor see any reason to OC this pooter. Spec:
Intel C2Q 6600 with Thermalright tower cooler and HyperX 12cm fan.
DFI Lanparty 680i LT Mobo
4gb DDR2 RAM
1x 250gb Seagate hdd, 1x 160gb Seagate hdd
1KW Antec PSU
ATi x1950 512mb grahics card, dual monitor setup
Antec nine hundred case (the main reason it now sits so cool).
The temperature readout you're looking at is the socket temperature, not the Core. Scroll down to the bottom of HWMonitor and maximise the CPU bit.
yea, even with my fans off (im on air btw) my "cpu" only hits 22c but my cores are a steady 56c.

Yeah - my "CPU temperature" is below room temperature...
CPU Temps around 30 under normal use with the case fans off
slaxor its the hr-10 it takes all the heat away from the back of the socket and it alone knocked 5c off my idle temps, add the fact the ifx-14 is almost as big as a house and alone is a very good cooler. i think i have only ever seen that read above 30c after hours of gaming as the gpu heats up my case alot more than anything else but that is due to the way i have my airflow.

green line at the bottom of the chart is my cpu temp, look how high it gets
Coretemp had my cores idling at 33ºC last night in a 23ºC room.

9oc?
Yep.
http://i27.tinypic.com/2rc5ov8.jpg
Nope. Here are the temps after a couple of minutes running Orthos. I get the same temps with this CPU on 2 different motherboards by different manufacturers each using different harware monitoring chips. The CPU is air cooled using a Gigabyte G-Power Lite and sits in a wind tunnel with a 120mm fan at each end.

I dont get how it can be 9 degrees, you dont live in the north pole do you? It is impossible for temps to be below ambient without phase change or liquid nitrogen.... It is a core temperature error.
It's a know issue with the DTS on the Brisbane core. The margin for error is +/-5*c. Oh, and air flow past the CPU cooler can reduce temps to below ambient under the same principal as wind chill factor.
Yes, but isnt wint chill how it feels rather than the actual temperature?
I dont profess to hold a degree in thermodynamics, but my understaning is that the process of airflow over the hsf has a similar effect to that of the skin by removing the insulating layer of heat surrounding the hsf unit and makes the cooling process more efficient. Guess I'll have to get the micrometer and thermal probe out to see whether I'm just full of it.:lol: But no, it doesnt just feel colder, it actualy is colder.
There's quite a long argument for this but for all intents and purposes in the context of a computer, ambient temperatures inside a case will always be higher than outside, where the components cannot be any lower than that. I'd say the margin of error for your CPU is probably quite a lot more than +/-5c unless your room ambients are actually below 10c.
But surely with skin, the skin is hotter than surroundings so it will feel colder as the extrematies lose heat, while not actually being colder?
Quite right. The skin is also cooled by sweat that's being evaporated as well.
Also temperature differences make cooling more effective, a small gradient like is 'seen' here is nigh impossible compared to a Q6600 running at 30 degrees with a big overclock and good cooling.
how many of u guys leave case open
iv heard open case is cooler
and iv heard a closed case cooler becouse it keeps cool air trapped in so that it doesnt adjust to room tempriture
so which one is it?
Closed for me as I have a side fan in my window.
Antec 900 is a bit like a wind tunnel, doesn't work as it should with the side off as the air intended to be blown over components gets vented out of the side if the panel is off.
Just on the "wind chill" thing.
No, the core can't be colder than the room it's in.
More air coming into contact with something means heat can be transferred faster, so if the CPU is hotter than the air, it will cool off faster.
But the air coming into contact with the CPU is always the ambient temperature, it can't cool the CPU down lower than it's own temperature. Wind chill just means your skin gets cold faster, taking more heat from your body to try to warm your skin up again and lowing your internal temperature.
So if you blow room temperature air over a CPU at 9 degrees, you'll warm the CPU up, not cool it down (in theory). Heat follows a temperature gradient, always going from hot to cold.
Essentially, your CPU will never be cooler than the room it is in. If your temperature monitor says so, it's wrong. Unless you have a super-fan which defies the laws of physics :)

Fiiinally... someone who can explain it better than me! :lol: :lol: :D

I remember physics class. I asked my teacher "if a super nova explodes a 2563 light years away from us, how many days is it till we can hear it?" and he was stuck on that for 2 whole days.... until he realised it was a trick question. I love myself.
And I also remember that heat transfers away from things, until it is balanced out. You cannot gain or lose energy, it is converted. If talking about a pc, it cannot get colder than its surroundings, or anything within its surroundings, unless it has no surroundings...Therefore it cant get colder than....-336 or something.. ? lolz I dont remember the magic cold number.
But this isn't why I'm posting (i just thought it might be fun to post :P ), how do i find out my temperature ?
-273.15 degrees celsius is the magic number. That's the same as 0 degrees kelvin, or absolute zero. Essentially, energy is movement, for the most part. Heat is particles moving, vibrating etc. Absolute zero is the temperature at which the particles stop moving, and is the coldest anything can possiby get.
I believe the record for the lowest temperature is still held by Lancaster University physics department, at something obtuse like 3 microns above absolute zero.
Anyway, back to topic, cpu-z is one way to get temperatures. It's the one I use anyway :)
Cpu-z for temps? Have i missed something?
Think he might mean core temp ;) it looks very similar.

perhaps he means cpuid hardware monitor by the cpu-z people?

So if im in a really stupid hit room (my office upstairs), then my pc will only get as low as the temperature it is in my room?
Check out your avavtar!
whats wrong with it
my fans, case and heatsink must be alien then, or posably from a planet that was orbating the star we heard go supernova lol
so, hyperthetically speaking; its 15c out side but the wind chill factor makes it feel like its -5c, what does a thermonitor read thats out side?

Yes, but it won't actually go that low, because the cooling won't be 100% efficient. Liquid nitrogen will do it, though. Liquid helium would be better ;)

15c.
"Feels like" is something people think, a thermometer wouldn't get confused. Wind chill is more about how fast you cool down, than how cold you end up. That's how it can "feel" colder without actually "being" colder
