Safe max C2D temps?

[VirtualLarry]

E4400 on a Conroe865PE, running at 2.8Ghz at stock volts (list is 1.325, mobo reports as low as 1.25-1.3), temps are 61C running large FFTs, and 69C running small FFTs. Stock heatsink and paste. Are these temps bad?

I'm running 71C with my E6600 with stock everything and I haven't had any problems. It's hot, but it's stable.

Every CPU is different when it comes to heat resistance, so it's ultimately up to your chip and your comfort. 69C is way over Intel's guideline, though. (I think they recommend 60C max for C2Ds)

69c is rather hot, usually people try to keep it at 60, a few bold ones try to stay below 65c. But the temperature sensors aren't all that reliable. You should consider throwing on a arctic freeer 7 pro or whatever for 15-20 bucks. It will take temps down quite a bit.

man I must be crazy then, I dont like even like seeing 50c that much. I would definatly consider investing in a better cooler if you plan on keeping your computer for long

Intel C2D stepping list

Look at that, there is only one E4400 stepping entry. Click on that, and it shows:
Thermal Design Power: 65W
Thermal Specification: 61.4°C
Core Voltage: 1.162V-1.312V

So the question is, is that thermal spec measured on the outside of the case in the center, or do they mean the temps as measured by the DTS inside the core? Because if it's the former, then I'm probably ok, otherwise, not.

Another interesting thing is that the core voltage spec seems wrong. CoreTemp reports my default vcore to be 1.325v, which is above the range that Intel lists, although not an unusual vcore in general for C2D chips.

61.4C is at Tcase, which is the top-center of the IHS so your temps are likely safe.

Is the chip throttling? I think you want throttlewatch or cpu-z for that.

See my remark in the current post with someone wanting help with his E6420.

As I said there, while the reports about OC'ing potential with the stock coolers of the C2D line are "good," I wouldn't bother even casual over-clocking without investing maybe half a Franklin-note in a good heatpipe cooler.

You're saving a lot more than that (until Intel prices come down this summer) by avoiding the top-of-the-line CPUs. Use some fraction of the money to get good cooling. Read the Anandtech review [published within the last few months] comparing some 15 or more coolers with the ThermalRight U-120 and U-120-Extreme.

Download RMClock and repost IDLE and load speed. Should be around 30C idle, and 65C load.
