Lower temps after overclocking Kaby Lake?

Bmachang · April 18, 2017

Hello! I was dialing in my overclock on my i7 7700K and I noticed that my temps are actually about 7-8ºC lower than when it was running at stock frequencies and voltages. I got it to 4.7 GHz @ 1.3 V so far but before everything was set to auto and it was 4.2 GHz @ 1.2 V supposedly. My question was if anyone else experienced this when they where overclocking their Kaby Lake too (or any CPU for that matter) and if anyone had could tell me why.

Room temperature before 35°C, now 20°C?

Either that ^, or if you have an air cooler... the fan speed is ramping up to a point where it's more effectively removing heat from the heatsink.

Could be a combination of faster fan speed + ambient temps though.

I thought that at first so I tried again another night to see test it and still got the same results. I live in a tropical climate so the temps are pretty consistent and I don't live in AC so not sure if room temps could be a huge factor like that. I was using an AIO for both but I kept the fan curves the same. The only thing I can really think of is that my mobo was over-volting my CPU under the auto/stock setting until i set it to sit around 1.3 maybe? do they do that out of the box sometimes?
