So how hot are you?

Ryna

As I've indicated in posts recently, I've built a new I7 system and am experimenting with overclocking for the first time. With my I7 920 (2.6 Ghz standard) and a fancy big Scthye cpu cooler, I'm getting a nice stable 40 C temp. when OC'd to 3.2 Ghz. I was just wondering what temps other people have, whether OC'd or not, and what platform. My laptop, running a Core 2 Duo P8600, scores about 42-43C under no load, which ain't bad I guess when the ambient temp is 30+ C (summer in AU). But anyway, what is safe on a laptop CPU?

So, as I say in the title, how hot are you?

i7 860 here, using the EKL Alpenfoehn Brocken HSF.

Idle is around 40 C, with 8 Threads running Prime95 it can go up to 55 C.

Using the stock cooler I got to 72 C (the threshold) in 5 to 10 minutes running Prime95.

Scrublet

My stock i7-920 is using a 90mm Scythe cooler, and it's sitting idle at 26C. I haven't done extensive testing with it but alt-tabbing during Borderlands showed a temp of 29C. I prime95'd for 30 minutes once and hit 32C. Obviously I plan on OC'ing as soon as I get the time to properly test and validate it as I do it. I should mention that the room temp is pretty low given that this is in a basement.

Is that 1 thread or 8 in Prime95?

Scrublet

8. Again, I didn't leave it running that long and have not done extensive testing. With school fucking my world up for the near future and work still behind from all the east coast snow it may be a couple weeks before I get to the OC.

How are you guys checking temps? I have an i7-860 and I'm using a Gelid Tranquillo.

Posted this picture of it in the general computer thread;

Also. I thought this was a funny comparison.

Gigabyte includes a tool called EZTune with its motherboards (I'm on version 6). The thing is pissing me off though...I can't use warnings because the thing is throwing a shitfit about a fan being at 0RPM (cause it can't monitor it). And it won't let me turn the warning off. I've got some BIOS testing to do later.

busfahrer

I'm using the retarded tool that came with the board (Asus P7P55D). Tools from manufacturers always seem to be retarded eyecandy.

But you can also use HWmonitor from the makers of CPUZ. That shows temperatures for the individual cores, and for the GPU and HDD. At least it does for me. No idea how accurate those are, though.

Ryna

Core Temp is an easy an useful tool to .. well .. check your Core temp.

exis

When I was OC'ing I used RealTemp, which is supposedly more accurate than CoreTemp for the CPU's it's compatible with. I did notice that my temps were consistently lower according to RealTemp, and as far as I could tell, closer to what I was seeing when I'd boot into BIOS (but obviously temps in BIOS are going to be different to regular temps).

I'm looking at about 40C stable running an E8400 clocked from 3.0GHz to 3.6GHz, in a room that I guess is around 20C most of the time. When I was first overclocking the highest I ever saw in Prime95 was mid-60's. My CPU fan was slightly loud, and apparently SpeedFan isn't compatible with my motherboard, so I just run the fan at low-speed and keep an eye on temps when I'm running new games etc. So far I haven't had any issues. I actually went ahead and disconnected two of my case fans because the readings I was getting from my motherboard and GPU indicated that the having 4 90mm intakes, 1 90mm and 1 180mm outtake was pretty excessive for how hot the interior is getting.

I really need to go and clean my case out though. I know for a fact there's a lot of dust sitting on/around my fans at the moment.

Shadowfire

According to CoreTemp, I'm running around 55-59C on all four cores after an hour of Dragon Age. This is an i7 laptop (ASUS G51Jx).

As for what's safe, from what I read that depends heavily on your cooling situation. This laptop supposedly runs pretty stable up to around 80-85C (CPU and GPU, though I'm not sure how to check GPU temps).

Scrublet

I seriously doubt that Shadowfire, considering that the Intel spec for the i7-920 is 67.9C. A CPU running at 80C is probably slowly deteriorating whether or not it's crashing. That is really hot. Though looking here I see the i7-860 is 76.7, which is news to me. Still though, 80s?

Where are you getting those figures from Scrublet?

JustinSane07

I have an overclocked Q6600 and an Artic7 cooler. It idles around 40 and at full load goes up around 57-58.

Last night it was idling around 56 and I couldn't figure out why. Nothing was running. I restarted the computer and it was fine.

Jasconius

My C2D in my Mac Mini has consistently gone over 170F under full load.

Apparently this is normal for the Mini. So I am guessing that's around the upper limit of temperatures.

Every number I quoted is from Intel's processor specs (you can find these at www.intel.com), except the figure on 80 degrees. That's just a given that 80 degrees is a very hot temp for a CPU to be running at. I don't know as much about GPUs, I think they tend to run a little hotter, so I'm not sure what a max safe temp is for them. I would never allow a CPU to run at 80 without doing something about it.

I'm pretty sure laptops are designed with high-heat tolerant CPUs and GPUs, because of how thoroughly crippled cooling solutions are for such a small form factor. There's a considerable difference between the 720QM and the i7-920, I'm sure.

looks like you're right. It's listed in a diff place under a slightly different name, but seems to say your 720qm is specd up to 100. That still seems insanely hot to me to not suffer longterm at all but I didn't build the thing so maybe they've got a way to deal with that.

So ignore my ignorant ass shadowfire looks like your laptop is well within tolerances.

Shadowfire

I wasn't worried. ;-) I've had one crash so far (Win7 related, not caused by the laptop) in the couple weeks I've had the system, and otherwise it has been running solid. Dragon Age at 1920x1080 with max settings and a flawless framerate? Yes please.

elliotw2

The P4 has a strange temp reading, it has three, only one reads anything.

The low temp I have is 57C (132F), the highest is 68C (154F)

I'm new to this, only just downloaded speedfan.
According to it the core temp is at 38c wwith the HD0 at 44c. That seems high.

What setup/CPU are you running Isy? From what I've seen, it makes a difference..

HDDs @ 45c is normal.

Its a stock dell c521. Old.

Windows XP Sp3
AMD athlon 64 X2 dual core 4200+
2.2GHz (I assume this would translate to 4.4 seeing as it's dual core?)
3GB DDR2 Ram 533mhz (or whatever it is )
Radeon X1300Pro 256MB
Stock 280 psu

edit:stigweard. Yeah that's what I thought but every game I tend to play freezes after 10-20 mins with some artifacting first. Reading up on it I found out that it tends to be the cpu overheating that causes the games to freeze like that. (Note, no slow down in fps, just artifacting out of the blue and then instant freeze leading to VPU error).

edit2: Opened it up. Saw a huge amount of dust. Cleaned it out, as best I could anyhow. Seems to work better now. Dark Messiah runs for more than 20 mins which is a good sign.
