65 degrees celsius... completely fine?

I noticed my e6550 was running at full load while doing some video encoding and I decided to check the temperatures. According to CoreTemp, it was getting up to 61 after ten minutes of encoding. I'm assuming it may creep a bit higher, but I doubt it will get above 65. So, is this too hot, or is it fine to do for a few hours every few days?

It is slightly old, though still more than I need, so I don't care much about it. However, I would be interested in pushing it further. It's currently at 3.35 with a small increase in voltage. I can't remember, but I think its at 1.38, up from the stock 1.35. I'm thinking once I get a laptop for college I will stick it up to 1.42 and see what that does.
 
CoreTemp should show you what you're CPU's Tj. Max is, which should tell you how far you are from possibly causing harm to your CPU through temperature rise. If you're E6550 is the G0 or M0 revision, then the Tj. Max is 80°C. If it's not one of those revisions, then it's going to be one of the following; B2, B3 or L2, in which case the Tj. Max is 70°C.

I would say 65°C is fine, especially as its already overclocked. But if your going to be overclocking more I would suggest getting a better heatsink, especially if your Tj. Max is 70°C, in fact if it is 70°C you should get a better heatsink regardless of whether your going to OC more or not.
 
I already have a pretty good heatsink, so I doubt getting a better one would lower it more than a degree or two. As for the Tj. Max, CoreTemp says it is 95 degrees celsius. Is this right?
 
CoreTemp doesn't always show the correct Tj. Max and one should always do some research on the matter, I found that I had to adjust the Tj. Max in CoreTemp for the temperature to show correctly. In the folder where you have CoreTemp there should be a CoreTemp.ini if you've run the program once. The string TjMaxOffset=-0; is what needs to be changed, for me it needed to be set to TjMaxOffset=-5;. I think CoreTemp works on the assumption that the Tj. Max is 100°C, which is not always correct. According to Intel's specifications the E6550's (revision G0) thermal spec. is 72°C, which means that the Tj. Max is a few degrees above that due to the difference in temperatures caused by the difference in placement of temperature sensors. Also what revision is your E6550?

I have a Q6600 and my Tj. Max is 100C. That seems really ****ing hot to be the max I can push it. I thought 60C was ideal for max at full load and 65C was the most you ever want to push.
 
eh as long as i stay under 68C im happy. hell, four inches away, there is a video card nearly breaking 80C lol.
 
Usually Intel CPU's throttle (lowering the clock speed and core voltage) when the temperature rises to 5°C from the maximum and will shutdown at the maximum temperature.
 
CPU cores can go up to 100C and not take any damage but I would say keep it under 60C under a load if you can.

My Q9550 idles about 38C and goes up to about 50C under a heavy load and I just have a nice case with good air flow and a cheaper after market heat sink/fan combo that has heat pipes in it.
 
Okay, well I think it's fine then. My temps would be good, but I have my computer in a cabinet so it is boxed in by wooden paneling so its like a little oven with very little airflow.

I checked in CoreTemp and it said I have G0. How do I sent the Tjmax to 80C? I tried entering -20 in place of zero in the coretemp.ini file, but that doesn't seem to do it.

I'm not sure what Tjmax is - but if you're wanting to set the max temp for alarm to sound - I think I saw that in my PC bios when I was getting my PC up and running. You could pobably set the max temp in the bios.

You can also go to the Settings part in CoreTemp's Tools section and set it there, should be called Tjunction Max offset.

Tj. Max is basically the maximum temperature die itself can withstand. Unlike Tcase, which reports the temperature at the IHS, Tjunction shows the die's temperature, which is more crucial and is usually a few degrees more than the temperature reported by the Tcase sensor.
