Who are you asking about?
What kind of CPU cooler are you using?
Your cooler is the Nzxt Kraken X62, right?
It seems like you're not facing any thermal issues.
Check the guide you were linked to for any differences or missed steps.
Maybe the problem lies in your overclock settings—currently at 4.5ghz it's crashing but temps are normal.
The guide suggests adding more voltages, so now you're at 4.6ghz and still testing stability.
Who wants to know what CPU cooler you're using?
My cooler is the Nzxt Kraken X62, so it seems like you're not facing any thermal issues.
Check the guide I shared and see if anything differs from your setup or if you missed a step.
It might be why you're not reaching turbo speeds on all cores.
Will adjusting the fan direction—front toward the radiator instead of back—help improve temperatures?

Will adjusting the fan direction help? Should fans point forward instead of backward?
........... I got a bit confused there.
If the radiator is at the front, the fans need to be set up so their front faces the front of the case and the back faces inward, allowing air to enter from the front and exit through the top or back.
But those temperatures you mentioned—are they under load or just idle?
What CPU cooler should I use?
My current cooler is the Nzxt Kraken X62. It seems like you're not facing any thermal issues. Check the guide I shared to confirm if there are any adjustments needed or if you missed something important. This might explain why you're not reaching turbo speeds on all cores.
Will adjusting the fan direction help?
If the radiator is in front of the case, make sure the fans are set so their front faces the front of the case and the back faces inward. This way, air enters from the front and exits through the top or back.
Are those temperatures you're seeing under stress or at idle?
Your cooler is on top of your case, and the temps are around 30-50°C during full load but 100% idle.
It seems you might want this phrase rephrased. Here is a revised version:
You likely need to restart the BIOS to the default settings and begin fresh.
Consider trying to reach 1.35v and aim for 4.7. Although others manage higher overclocks at lower voltages, this often depends on the specific silicon used. You might end up with a chip that overclocks slightly below what you achieve at a higher voltage, which is just part of the challenge.
It's reassuring to note you're currently at 4.6, giving you a 0.1Mhz boost across all cores. But if you push it to 1.35v without success, consider increasing to 1.4v. If that doesn't work, try 4.8. Should it fail at 4.8, move up to 1.4v again. If it still doesn't stick at 4.8 on 1.4v, revert back to 1.35v and see if you can go further.
If 4.7 doesn't hold at 1.35v, increase to 1.4v. If that also fails, return to 4.6 at 1.3v—the last stable setting you reached. Once you identify your ceiling, proceed to the next stage.
The next step involves gradually reducing the voltage in small steps of 0.01 until it becomes unstable, then incrementally raising it back up to where it was last stable. This helps ensure you're using the lowest possible voltage for your overclock. (Example: dropping from 1.3 to 1.29, then 1.28, etc.)
Once you've found the most stable voltage, thoroughly test its stability with various tools and benchmarks to push the CPU under stress. This process requires patience and time.
Typically, run a short FFT stress test for up to two hours. If you complete it, move on to workload testing—load it heavily for longer periods (4 to 6 hours) using full stress rather than just FFT.
If everything works, you've successfully identified your maximum stable overclock. Then, fine-tune efficiency by adjusting the load line calibration. Use CPU-Z to monitor the voltage during tests. Aim to keep it steady and avoid dropping below the set overclock voltage.
If the voltage falls below the configured level in BIOS, it's called V-Drooping—a sign of instability. Acceptable fluctuations are when the voltage rises briefly, known as overshooting. Higher load line calibration reduces V-Drooping but increases overshooting. Balance is key: stop V-Drooping while managing overshooting.
Once V-Drooping ceases, you've reached your optimal setting.
The system started at version 4.7, but crashing occurred when launching certain applications like adia64. It also showed a boot time of 1.35v.
It means it booted, which can go either way.
As I mentioned in my previous post.
When I say "if it sticks," I'm not referring to whether it boots.
I mean "if the overclock remains stable."
That clearly isn't stable—try going up to 1.4v and run some stress tests to check its stability.
