i5 4690k 1.03v at 4.2ghz
Hi
Just checking if my CPU is in good shape before trying to overclock to 4.2ghz.
Prime 95 @ 10 minutes
Real Temp
CM Hyper 212x single fan installed
4.2ghz @ 1.25v = 90+ C close to burning it
4.2 @ 1.2v = 90 C not ideal
Lowered voltage to 1.05 but temps stayed between 80-86°C
Then back to 1.03 and got 67-85°C max
I’m worried about overheating and performance limits.
I'm testing a 4690k at 4.2GHz with the original cooler and a Vcore of 1.09V. I don't stress test it with Prime; I use Cinebench and Hyper Pi for testing. The temperature reaches around 78°C on core 2, and the rest stay in the low 70s. My PC runs smoothly under normal conditions, but during video rendering or heavy tasks, the CPU stays just above 70°C, which is acceptable.
You should reposition your cooler, as it isn't fitting correctly. My friend with the 212 EVO has temperatures far below yours, even his stock model is close to that level.
My 4690k reached 4.6ghz at 1.23v, 4.7ghz at 1.27v and 4.8ghz around 1.32-1.35v.
Sergeant_Sneaky shared his experience with the 4690k on the Hyper 212: he achieved about 70c at 4.5Ghz using 1.2v with prime95 for more than an hour. He suspects the thermal paste might not be applied well or the cooler isn't properly seated.
Thank you for your prompt reply—I've adjusted my 212x cooler and noticed a slight variation.
At 4.3ghz at 1.06v, my maximum temperature was around 78°C, fluctuating between 75-77°C.
Prime95 after 20 minutes: I can't reach 1.2v because the CPU overheated at 90C, but I managed to overclock to 4.5ghz at 1.13v with stable temps of 80-85°C.
Most users can push it to 1.25v on a Z97M-D3H with a CM series cooler, but mine struggles.
I'm also confused since I'm seeing high temperatures yet achieving low voltage during stable runs.
I'm using z97m-d3h and a Tecware Reiden case with three front and two rear fans.
Apologies for the poor English.

Arronleeds says you should reposition your cooler, it won't fit well. My friend uses a 212 EVO and its temperatures aren't that high. Even the standard cooler is close to that level if not better.

Thanks for your prompt reply. I changed my 212x cooler and noticed a slight variation.
4.3ghz at 1.06v, max temp was 78°C. It was fluctuating between 75-77°C.
After 20 minutes with prime95.
I can't run at 1.2 because the CPU overheated at 90°C.
But I managed to overclock the CPU to 4.5ghz at 1.13v (stable), temperatures stayed around 80-85°C.
Most users can reach 1.25v with a CM-212, but mine doesn't.
🙁
I'm also puzzled because I'm seeing high temperatures yet it can run low voltage on a stable setup.
I'm using z97m-d3h.
Tecware Reiden case has 3 front and 2 rear fans.
My apologies for the poor English.
Try another benchmark—Prime95 isn't the only way to check CPU stability.
If you experience high temperatures with Hyper Pi or Cinebench CPU Render, it might indicate a faulty cooler or CPU.

Make sure you're using Prime95 v26.6 (the version matters since newer ones can cause extremely high temperatures).
Your English is fine by the way.
Sergeant_Sneaky shared his experience with Erick Jaie. He mentioned that the cooler installation isn't ideal for the 212 EVO model, noting that even the stock cooler performs close to the high temperatures. He reported achieving speeds around 4.6GHz at 1.23v, 4.7GHz at 1.27v, and 4.8GHz at roughly 1.32-1.35v on his 4690k.
He also discussed his own results with a Hyper 212 cooler, achieving about 70c at 4.5GHz with 1.2v using Prime95 for over an hour. He suspects the issue might be related to thermal paste application or cooler seating.
btw i'm running at 26.6v.
i'm out of thermal paste because i've seated it 5 times.
i had a g3258 before it was clocked at 4.3ghz @ 1.24v, getting 75c max on my 212x running prime 95.
then i upgraded to 4690k, but now my temps are higher than before, so i'm using low volts.
my idle temps are 43-45c. do i have a defective cpu or a cpu cooler?

Then I upgraded to 4690k, but now my temps are higher than before, so I'm using low volts. My idle temps are 43-45c. Am I having a defective CPU or is the cooler not working properly? How much paste am I applying? It's possible your chip has bad contact with the IHS, though that's rare. Have I asked if opening the case helps?
