It depends on the CPU. Some people may have some temperature all the time while for other types of CPU that would be overheating. My old Pentium IV was at 70C, with 75C being the limit. Yet I see people with 80C as a normal temperature; that's because it *is* a normal temperature for their CPUs.

My Pentium 4 2.8GHz runs at an unbelievable 43C under load. I triple checked it's using the correct sensor, for when I exit BOINC, the temperature drops to 31C.

What a new motherboard and some dusting can't do. ;-)

I run my 8 computers 24/7 crunching 100%.

The highest temp is 53C on my AthlonXP3000+, as I think the copper ThermalTake HS&F may not be seated quite square atm. All of the others run at sub 50C on standard air. I worry at 50C+ and take action at 55C without delay.

Sekerob and particularly Nicolas must either be getting bad temperature readings or be the luckiest people on earth. 'cause the critical temp for a P4 is 69C and it's all over when that gets passed. I can't imagine them not shutting down at those temps guys. Most accurate temperature readings, for Intel chipsets only, are found in the TAT program available for download from Microsoft. It gives real time temps in 0.1 Deg increments and loads your system even harder than BOINC!

Hottest thing here, no she's not looking, is an old ASUS MoBo, running an OC'd CeleronD. The CPU runs nice and cool but the MoBo will boil the kettle for the nice cuppa tea one needs, to settle the nerves, while awaiting the inevitable disaster...

Cheers.

I actually looked up temperatures for my CPU, and max was 75C.

After more than a half year of continuous crunching, my C2D T7200 notebook's cooler has been more and more dusty, the temperatures tried to rise past 85°C if I did not keep the frequency low, and in spite of pretty loud fan. I think the highest temps I've seen were just under 89ºC, but usually my RMClock did not allow it (I've set frequency throttling at 85°C). It helped a bit to occasionally blow powerfully through the cooler ribs from outside (with closed eyes and nose ;x), but just for a short time (few weeks).

After opening the case, removing few larger dust clumps from the ribs and cleaning the ribs with tiny inter-tooth brush, the temperature under full load now stays under 65ºC, on the second fan speed stage. (I wonder for how long.) (Well, can't compare the tiny fan with huge desktop cooling systems :-)

Hi,

my Q6600 runs at < 45° at default freq 2,4 GHz. I've a cheap but good Thermaltake water cooling system. I use this cpu since a few days. Before I had a E6600. It runs at max 47° overclocked at 3,2 GHz instead 2,4 GHz default. I wanted to increase the frequency but at 3,3 GHz were errors at prime95. I think my power supply its not the very best. The vcore degreases significant when I use the cpu fully loaded.

The temps of the new quadcore are not very good. I dont know why. The cooling system is the same than before. I ve to check it somewhen in the next days.

Buts its nothing: I had a pentium 4 3,4 GHz in a ready build computer from a (super)market. It climbs up to 86° C. I bought a new cooling device. It degreased to 65° C.

Maybe the Q6600 is higher temperated than the E6600. It takes 95 w instead of 65 w at full load.

While the oc-test of the E6600 I saw, that I had under BOINC 1°-2° C more than with prime95. Both run for hours when I'm checking the temps. Did anyone saw something similar?

edit: something about my case: economy classe office case. Only one case fan, and one on the graphics device.
