i7 4790k with 4.6ghz overclock voltage
Hi Toms!
I pushed my i7 4790k to 4.6ghz using a 212 evo and it's currently stable at 1.26v. Do you think the voltage is too high for that speed? I used 1.25v for stability, so what are your thoughts?
Temps are around 80°C with spikes up to 85. Is that the maximum capacity of the 212 evo? I'm using the stock CM paste.
Thanks for any advice!

Hello Toms!
I pushed my i7 4790k to 4.6ghz using a 212-evo cooler and am currently stable at 1.26v. Do you think the voltage is too high for that speed? I used 1.25v for backup, so what are your thoughts?

Personally, I’d consider going up to 1.3V on an air cooler if temperatures stay moderate before they get too high. If temps don’t spike much, 1.35V on a solid water cooler would work well. It looks like this chip is capable—most other DC chips I’ve seen can’t reach 4.5Ghz at 1.3V, except one that hit 4.9Ghz at 1.28V on a cryo H5.
If you want to confirm whether you haven’t increased enough core voltage on your CPU, one sure method is to check for a BSOD, crashes, or freezing during a 95 test or under heavy workloads. The maximum temperature you can expect from your CPU is around 100°C. The Evo 212 cooler works well for most I5 configurations, but with an I7 it drops to about 80°C. Since you’re using an I7, you might need a better CPU air cooler—such as the one recommended—which can reduce temperatures by around 20°C. However, this cooler is larger, so ensure there’s enough space. Consider the Quiet CPU Cooler with two NH-A15 fans (HS-026 NC) for quieter operation. Alternatively, opt for an Aio water cooling loop setup with a minimum 240mm radiator size to maintain stability. Temperature plays a significant role in overclocking performance, and keeping your CPU as cool as possible is just as important as adjusting the core voltage, Johnny.
So? I got stuck in the dark? Lol
I ended it at 4.4 with all cores on and 1.2v, cache at 4.1 and auto voltage. That kept the EVO running smoothly.
