Q6600 safe temperatures for 24/7 operation

[Chicken76]

I wasn't paying attention to this aspect during it's days of glory, but now I need to keep one on 24/7 and with summer almost upon us I was wondering what is the limit temperature wise. Does anyone remember?

If I recall right tjmax is 95C.

What are you going to be using the CPU for?? If you are going to be keeping your pc on and hammer the CPU 24/7 then you may want to try to keep it a bit cooler. I say try to keep it under 70c for 24/7 use and you'll be fine. Specially if you are overclocking the CPU which I am pretty sure your doing?? Dont know what your using for cooling but maybe check into grabbing a Hyper 212 Evo for $25-30 will do what you are needing.

IME especially with hungry CPUs, the motherboards and PSUs crap out long before the processor...

at 1.5v and >72.4C I had issues on 65nm core 2's.

 

[Chicken76]

Yes, I am overclocking it to 2880 MHz (320 x 9) and it's "hammered" but not on all cores. I do have an aftermarket heat-sink on it.

Would you say a constant temperature in the low 50s Celsius is safe for long term operation?

That is under load? Heck, my OC'd Q9450 idles at temperatures around that, and that's been entirely stable for years. The only concern I would have is silicon deterioration due to OC'ing and high voltages over time, but even that shouldn't be too much of an issue.

I dont see an issue running it 24/7 at stock clock at 90C year after year.

Yes, that is under load, but not 100%. On average, 2 of the cores are at 100%.
As I said earlier, it is overclocked to 2.88GHz. The VID used is 1.325v. The voltage reported under load is 1.25v. Would you say in my case silicon deterioration due to OCing is going to be an issue?

Definitely not. 1.25v is lower than quite a few G0 stepping Q6600's VID, which is the voltage specified by Intel that the CPU needs to run at stock clocks.

edit: Is low 50s your socket temp, or core temps? Socket temp is the one that SpeedFan calls 'CPU', directly above the core temps.

It's the temperature of the hottest core. The motherboard does not report correct temperature values. (they are negative)

Voltage is the primary problem maker for chips, not temperature (as long as you stay below tjmax)

VID Voltage Range 0.8500V-1.500V

When i do mining I hammer all my chips 24/7 at 90C. have over a dozen CPUs and 3 dozen GPUs, none have died yet. CPUs are generally at lot more hardy than GPUs also. Most miners will tell you its rare to have the actual chip fail, its usually VRM on gpu or mobo.

Good temp for idle can be 40's C to 60ish C,,
