the i5 4670k's temperature exceeds 93c following a 4gz overclock.
Hello everybody,
I have a question about overclocking my CPU.
I have an aftermarket cooler and attempted to OC my i5 4670k to 4Ghz using the default voltage.
However, after running Prime95 and starting a stress test, my HWmonitor reported temperatures exceeding 90-100°C.
I tried further overclocking to 4.4Ghz at 1.350V, but it only got hotter and reached 100°C within a minute.
Could you please explain why the CPU runs so hot and suggest a solution?
Every comment is welcome!
I'm not an expert, but keeping the default voltage on seems likely to be the reason it's getting very hot. My setup is at 4.4ghz with 1.225V and it never exceeds 70 degrees. Edit: Sorry, I didn't notice you tried adjusting the voltage to 1.35v - I've read those chips are tough to cool. From what I've seen, it's rare to maintain a stable temperature at that level of voltage.

You're asking about the aftermarket cooler you have. Just because it's not the original one doesn't guarantee better performance.
What were the temperatures during stress testing before OC?

I have this cooler here:
http://www.lc-power.com/en/product/power...lc-cc-120/
During stress tests at default settings, temperatures were around 73-76°C.
What voltage-to-GHz ratio should I consider?
I know CPUs vary a lot, but what's your ideal balance?

If you're getting nearly 80© at stock I'm not surprised you're overheating with a mild oc. That cooler isn't very good but I would expect better than that if it's installed properly and paste done properly
I just applied paste and tight it more with screw driver,but now PC won't boot,so I pulled out battery and now I'm waiting for some time so it may boot properly.Once it boot,I'll check temps.
If you're receiving nearly 80© at stock, it makes sense you're getting warm with a mild overheat. The cooler isn't great, but I'd expect better performance if installed correctly and the paste job was done right.
I was able to boot the PC and checked the CPU temperature using HWmonitor on stock, which was around 60°C.
I downloaded an older version of Prime95 26.2 because it's rumored to work better with Intel processors and provide more accurate readings, so that might be why it ran hot?
Now I overclocked the CPU at 4,3Ghz and increased the voltage to 1.330V, testing it for the past 15 minutes.
The maximum temperature reached was 82°C.
Is that a suitable temperature for the CPU, or is it still a bit too high?
PS
How long should I run Prime95 to confirm full stability?
