70 degrees - Safe?

Hi All,

I've had a system that I built now for about a year, and I've been experimenting with overclocking since I built it.

I have a Core i5 750 with a Noctua NH D14 cooler. I've finally decided that I would like to run a 4.0 GHz overclock as my primary setup.

I am able to keep all the C states enabled, but I have kept Turbo Boost off. Under full load in Prime 95 my temps are around 70 degrees centigrade.

Obviously this would only be hit in normal use from time to time, and the C states will keep it cool (around 25-30) while idle.

Is this a safe enough temperature to use everyday?

Good news....

I can't see why it wouldnt be ok... I game a bit on PC, but not extensively - and I can't imagine that gaming even touches 100% CPU load very often. Next time I play I guess I'll log the temps and see where that leaves me.

yeach hot temperature not good for hardware.
if u want more cool : disabled Smart fan in bios & Cpu temp wwarning shut down in 75*C (protect your hardware from damage ) or use dual Fan for Noctua , replace New thermal Pste AS5

I have switched my thermal paste already from the stock noctua paste - which is probably quite good - to Arctic Silver.

The best thermal balance I have been able to find so far is around 3.8Ghz, where the chip only really hits low 50's for temperature. I think this is an excellent trade off for the 200mhz difference.

Its not 4 GHz but in all honesty I don't think the CPU is my bottleneck for much.

50s is a good temperature. my i5 760 hits that at 58c at 4.1ghz i cant see why people need 4ghz+.......

Are 760's "binned" at all? Just wondering since you can grab 4.1 with such a lower temperature than I'm getting at 4 with the 750.

As a final report,

Playing around with the vCore voltages a bit and the load line calibration, I have been able to stabilize the temperatures around 60-63 degrees.

I feel that for a 4Ghz clock, this temperature should be quite safe, according to recommendations, as well as compared to standard temps that I see others getting.

Many thanks for the advice.
