super high temps oc i7 7700k
So yeah, I'm overclocking my brand new i7 7700k today. I used Artic Silver 5 thermal paste, which takes a while to take effect. But honestly, these temperatures are crazy—completely different from my H100i v2, which isn't even close. Before this, my i7 6700k was running around 70 degrees at 1.32 volts. I'm confused about why things are so much hotter now.
High temperatures are typical for a 7700k, yet I’m managing 4.8ghz at just 1.21v while keeping temps in the high 70s to low 80s with my 240mm cryorig a40 ultimate AIO. I believe the only solution is to vent, but that sounds risky and I’m unsure if I should try it. These units usually reach a stable clock just over 5ghz anyway, so it probably isn’t worth it.
The chip tends to overheat. Anticipate that behavior.
My h115i maintains a stable 4.8 GHz OC at 1.34 volts during 80°C under prime95 26.6 load.
You should clean and re-seat the pump. Check the grease distribution when removing it to ensure proper placement.
I use a Thermaltake TG-7, probably.
Idle speed is around 26 RPM.
What's your OC? 49x multiplier?
Install prime95 v26.6 and perform small FFTs. What temperature readings do you observe?
it was a 4.9ghz clock at around 1.35 volts, but performance exceeded 100. that’s not ideal, I wasn’t sure if it was due to artic silver 5 or something else. Maybe wait a week or two and check if it improves; if not, consider reseating the liquid cooling.
i have a link to my hw monitor while it was running prime

the chip runs hot—expect it to.

you should clean and re-seat the pump. Check how the grease spreads when you remove it and ensure you did it correctly.
i use thermaltake tg-7, I think that’s it.
i idle at about 26.

get prime95 v26.6 and run some FFTs. what’s your temperature?
Refresh it immediately to ensure proper paste positioning. Any version older than 26.6 causes excessively high temperatures.
Execute Google prime95 version 26.6 and perform minor FFTs.
Observe the temperatures.
Values above 26.6 require AVX instructions and lead to exaggerated temperatures.
Realbench might also be viable, but for optimal results, use version 26.6.
I display your Vcore at a maximum of 1.392 volts in that image. This is the setup I'm using for 5.0Ghz with a custom water cooling system. A temperature of 100°C isn't unexpected.
Arctic Silver 5 isn't regarded as a leading thermal compound, particularly given the price point. It also requires a curing period.

I'm testing a real bench now at 4.9 GHz, 1.376 volts, and it's reaching 100°C in just 4 minutes. That doesn't surprise me much. Will these numbers drop significantly after the Arctic Silver 5 stabilizes or should I consider something better?
Eximo shared that in the picture he posted, his Vcore reaches a maximum of 1.392 volts at 5.0Ghz with custom water cooling. 100°C is expected.
Arctic Silver 5 isn't seen as a high-performance thermal paste, especially for its price, and it requires curing time.
By maybe 5c. Lower your oc. You're going to melt your chip. That voltage is pretty high. Still within the recommended limit but your chip runs too hot.
If you want results you're gonna need to troubleshoot. I recommend reseating instead of waiting the curing time to find out it's wrong. If it wasn't wrong then that rules that out. It's a process of elimination.
