What Is The Maximum Temperature Stock Fan Core i7 920???

The faster you OC it and the more volts you supply, the hotter it will get, so there's not really a "maximum" of how hot it can get (until it physically starts failing, of course). The Intel datasheet for the specific CPU you're interested in will list the maximum "safe" temp.

I think the question is, what is the temperature of an i7 920 at stock speed and voltage under full load with a stock HSF? Intel defined some criteria for the minimum performance for a heatsink. What do they consider a maximum healthy temperature?

It's a rhetorical question. Unless someone has an answer of course.

Depends on ambient(room) temp, but mine is at stock around high 30's, low 40's. Loads are 50's-mid 60's, topped out at 71.

How about you explain your reason for asking this question. We can better answer you then. There is no SET max. Actually I believe it is 115C but you will NEVER want to even come close to that.

That's high. You see at 97.7% load there is 6 degrees left to TJMax for two of the cores? TJMax is where the CPU will shut down from overheating.

I think you should have had more margin than that, even with the stock cooler and 26 degrees room temperature. (I'm getting ~20 degrees to TJMax at 22 C room with an aftermarket cooler. I think core temps scale approximately linearly with ambient temperature, so you would have had maybe 10-15 C left.)

But I also think you are still safe, at least as long as you didn't turn off thermal management in BIOS. It's not too hot as long as you have a little margin to TJMax left, and as long as the "thermal status" i Real Temp is OK. (It will show a notice if the CPU is or has been too hot, check out the Real Temp documentation.)

Here are a couple of links for you:

"unclewebb" in this link is the guy that makes the Real Temp software. He thinks
the i7 stock cooler is "barely adequate" and recommends buying an aftermarket cooler.
The person posting his temps on the i7 runs even hotter than you. If that's a comfort

A Legit review here says that most aftermarket coolers shave 10 C or more off the Intel stock cooler temps under load. (Although I have heard others say they got very little difference.)

Not sure if the Real Temp sensor test is long enough to warm the heatsink. But if you run Prime95 for 10-15 minutes and have coretemps 80+ degrees, the heatsink should be uncomfortably hot to the touch. If it isn't, it suggests the processor doesn't transfer heat to the heatsink as it should, and you should try reseating it. (You will need new thermal paste.)

Good luck

The CPU lowers the clock multiplier from 21 to 20 when the case hits 70 degrees, so that's the temperature I think it's worth aiming for.

Hi,

I'm running stock cooler and prime 95 max temps hit 75C for me (on max cpu fan speed). I have the P6TDeluxe and have a GTX 260.

To keep my system quiet I run the stock cooler at 63% (when not running prime 95) speed and idle temps are 40C for CPU and 41C for MB.

I do find that with the GTX 260 being so close to the north bridge I think it's poluting the temps, because in Prime 95 CPU hits 75C and MB hits 43C.

when I'm in a 3d game max CPU hits 55C and MB also gets to about 55-56C.

Any thoughts? I considered moving the video card to the bottom PCI express slot to keep it away from the north bridge, but I foundit difficult to connect the wires for the power, was getting in the way of the indake fan of the video card. I may try that again and compare temps.

Guys,

This thread is a thermal train wreck, and a FUD-Festival! Newcomers have been dredging this up almost on a monthly basis since it was originally posted on January 9th! I'm too busy to watch the Forums like a hawk for a few days, and this damned thing pops up ... again?

Enough! Let's get this mess cleaned up and into perspective. I'm once again posting the following for everyone's benefit, so here's what you need to know. Please, read and heed:

You say there is a 5 degree spread? Then why do I get a 18 degree like spread? My cpu temp is like 20 degrees while my cores are bewteen 32-38 degrees...

Thanks.

I'm sorry I must have been speed reading. I have the Evga Classified and must be a nuance associated with the kind of board or the cooling system used? Its water cooled. The gap I think gets closer after it warms up a bit, but its always like a 12 degree difference where the cpu temp is like 20 degrees and the core is about 32.

On my Abit 680i board the two temps are almost identical with the core temp being a few degrees colder than the cpu temp. That one has a TRUE installed on it...

Anyhow, thank you. I will try to read more carefully from now on,

Dave.
