What is the maximum safe temp for an E6600? I just got one with the Asus P5W DH Deluxe board. If it makes a difference, I have 2GB Corsair XMS at 4-4-4-12. I'm using the stock HSF and it seems to do very well. Here's what I've noticed so far (all temps in F):<br />
<br />
No OC (2.4Ghz): Idle in the lower 70s, in the mid to high 80s under load.<br />
10% OC (2.63Ghz): Idle mid to high 80s, upper 90s under load.<br />
15% OC (2.75Ghz): Idle upper 90s, between 110 and 115 under load.<br />
<br />
I haven't had any lockups, reboots, or anything strange yet. How much further am I likely to get without problems? This CPU seems to OC quite easily...

As long as the CPU is under 55C it should be fine. The E6600 can get up to 3.2 on air very easily. You can go up to 3.6 or higher with high quality air/water or phase.

</div>Uh, 55C is more than fine for a C2D.<br />
<br />
Under 85C using TAT. It measures temps differently than other programs, is the only one ATM that shows the right temp. The temp sensor is in a different place, closer to the die.

</div>Ohh yeah lol for the C2D the TAT is fine if its around 85C because its the temp of the actual core, not the sensor next to it <img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" />

Ok maybe this is a ******ed question but are you sure 85C is safe? That seems terribly hot. I'm shocked that they release this at the lower speeds if they could have pushed them much harder. I could probably go over by 1G before getting that hot.

yep the smaller the die is the more heat they can take i belive but mine runs at load 74c and nothign bad i think 85 is the max

85 C does seem really hot.

can somebody link to somewhere that says 85C is the max safe??<br><br>
i've looked on the intel but couldnt find anything

What motherboard and video card you have? Is the case a mid-tower?<br><br>
Also, if possible, see if you can buy a Thermaltake Big Typhoon and some Artic Silver 5 paste, that is the best way to go with an E6600, stock HSFs are horrible.

i run about 66C load, is that ok on e6300?

Asus P5W DH Deluxe mobo in an aluminum mid tower case...I plan to buy the Big Typhoon VX when it's more widely available (namely off of newegg.com). I read somewhere that the regular Big Typhoon is not for C2D, but works on other 775 CPUs. Not sure if it would work or not, just don't want to take the chance. Anybody have first hand knowledge that they work ok on the C2D?<br />
<br />
And just my 2 cents, but the stock HSF is leaps and bounds better than previous stock coolers (like my old Athlon 1800 stock cooler). They've come a long way.

Users of Intel Core 2 Duo processors please be aware that temperature's of 85C are not acceptable on the processor core, neither on the CPU installation socket.<br />
<br />
With Core 2 Duo the sensor that is detected is the on board socket sensor. This temperature (depending on system configuration) will usually be about 10C lower than the actual on die temperature.<br />
<br />
To determine your CPU operating temperature (Core) please use the Intel Thermal Analysis Tool. This application has the ability to receive data from the CPU core sensors for both cores, this is very accurate (unlike most sensors). This is because the algorithm is more sophisticated <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" /> <br />
<br />
Intel Pentium 4 processor default sensors are on die, Core 2 Duo are not. Due to this fact people are getting confused between temperatures.<br />
<br />
Rated Operating Thermal Level of Intel Core 2 Duo processors is 60.1C, this can be acceptably breached if voltage is within a certain range of default.<br />
<br />
A temperature of 85C will be causing very slow damage to parts of the chip. However the shut down temperature is measured using the onboard sensor and therefore will not shut the system down unless the socket temperature breaches about 66C.<br />
A custom BIOS may allow the system to switch to the "on die sensor", then your system would not boot/operate if it's processor temperature is at 85C <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
These processors are not the equivalent of Core Duo/Dothan which are designed to operate at up to 100C <img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" />

yeah mine is at 52-58C idle using TAT<br />
<br />
that surely is too high?

If your processor is a Core 2 Duo Desktop (Allendale/Conroe) then yes a temperature range of 52-58C is not "very good". <br />
However the chip itself will not be receiving damage at that point, that happens about 80C+ (circuitry and transistor failure's).<br />
<br />
If possible I would recommend taking action to keep your CPU temperature within acceptable levels <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
Thermal Control 1 and 2 should be enabled for safety at those temperature's <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
The 65nm process has a decent ability to deal with high temperature, however it is still not suited to that temperature range (i.e. 70C+)

Yeah, I'd look into cooling that sucker down, bicolor.

I may need to get a New CPU cooler. But I dont want to splash out too much extra money on this rig. So I mite leave it. The ammount of money I could spend to get my PC to run that little bit better.. Im going to stop myself now.<br />
<br />
52 C Load. Maybe thats not the on die temp.

If you find yourself with some free time, you could try reseating the hsf with less thermal compound, if this doesn't help it could be something else, like air temperature<br />
<br />
But its worth a shot..

While I am certianly not going to state the "safe" temp of these CPUs is 85c, the stated 60.1c temperature threshold is stated by Intel to be measured at the center of the IHS. Given that, the must be some variance as there is little chance that the center IHS can be 60c if the Core is 60c as well.<br />
<br />
I have seen the 85c number thrown out a lot but never been able to get concrete proof of it.<br />
<br />
<br />
Regardless, the threadstart is quoting triple digit temperatures, are we assuming these are in F? As no one has acted shocked at 90 degree idle temps yet <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" />

Uhh guys he said 80 F not 80C...
