Hello everyone, I have a query regarding the temperature of my 7700k.
Here are my specifications: MSI Z270 Gaming Pro Carbon, i7 7700k, Corsair H100i v1 cooler.
Right now, I'm experiencing
4.7ghz - 1.225v - 58-60 degree full load temperature with OCCT in 3 hours
4.9ghz - 1.31v - 63-65 degree full load temperature with OCCT in 3 hours
5.0ghz - 1.38v - 75-77 degree full load temperature with OCCT in 3 hours.
I’m really pleased my CPU can hit 5.0ghz even with high voltage.
Which cooler should I choose for daily use? I mainly play games and occasionally render, and I prefer 5.0ghz. The temperatures never exceed 80 unless I run Linpack. The fan is quite loud, and I’m worried about the high voltage during continuous use.

Additionally, I’d like to know the voltage values:
CPU GT Voltage
CPU SA Voltage
CPU PLL OC Voltage
CPU PLL SFR Voltage
PCH Voltage
At 4.7ghz, I just need +0.05 for each, and everything stays stable. For 5.0ghz, I should leave it on Auto for stability.
Should I set them manually or let the system handle it? Would adjusting these voltages make the motherboard temperature drop significantly?
Thanks everyone.
Also, my CPU boots normally to Windows and normal apps at 5.2ghz, but crashes under stress. Any tips to reach 5.0ghz with lower voltage would be appreciated, since I think my CPU is fine overall.

you can simply lower the clock speed to 4.8 and boost the DRAM value to around 1.350, then gradually raise the BCLK. this approach tends to be more stable, though it depends on the specific RAM model you're using.

It seems like only a small improvement exists. The change is minimal, around 6%, and it doesn't significantly affect the outcome whether you're achieving 100fps or 106fps.

SkyNetRising says it doesn't really matter. The change from 4.7 to 5.0 is only a small boost—about 6%. It doesn't affect the experience whether you're at 100fps or 106fps. I guess the fancy number isn't that important.

I don't care about complicated things. But I would care if the CPU fails early.

SkyNetRising says it doesn't mind the usual stuff, but it would worry if the CPU fails early. You don't care, but I do. I understand that performance differences aren't really big, but I think most people don't upgrade their hardware just for speed, especially with a 7700k that's already at 4.5ghz in turbo mode.

They do it just to impress. Then they head over here, tears in their eyes, complaining about their faulty premium gear.
Do whatever brings you joy.

The herd believes the current setup is around 1.35. If the noise bothers you (that’s me), I’d lower the output a bit or switch to a more powerful cooler (unless budget matters). Everyone gets to decide about risk, cost, and sound. For me, an all-core 4.3 offers a big improvement without extra noise. Going higher isn’t worth it personally. As mentioned, 4.9 to 5.0 gives almost no noticeable frame rate change with warmer temps.

Even with a 5.0Ghz frequency, most individuals will likely upgrade sooner than the CPU can handle
