I overclocked my i7-4790K today. I went with a fairly modest 4.5Ghz, using a voltage of 1.20V. So far, things seem good (I use the PC to run X-Plane 11, almost exclusively).
As expected, the CPU temperatures reported at idle are now higher than before. At the moment it is pretty warm in London and the room with my PC in it is even warmer (2 PCs running in a small space). I am wondering though how many degrees C above ambient would be about average for a i7-4790K before and after overclocking. My idle at the moment is low to mid 40s, but the PC has been on all afternoon (and I am not sure of the temperature of my room as I write this, probably around 30 degs C).
With some tweaking of X-Plane settings, the increase in the smoothness of performance in the sim after the overclocking is very noticeable indeed, better than I could ever have hoped for, so I would not want to go back to 4GHz. I can't help but be aware of the temperature increase though. When X-Plane 11 is running, the temperatures I see in Core Temp are again about 10 degs higher on average than before I overclocked - now about 65-70C. Seems fairly safe though (no?). At 100% CPU usage, when X-Plane loads, there are short peaks of up to high 80s C, but they only last a few seconds and the temperatures go back down again. Before overclocking, those peaks were some 10-15 degrees lower however.
So does this all sound within the bounds of what would be expected (bearing in mind the higher than normal room temperature)?
Oh, the PC cooler is a Noctua NH-L12, by the way. Seems to work pretty well.. It's also (another important factor) a mini-form PC, with a ThermalTake mini ITX case and an Asus H97I-PLUS M/B.. Not so much room for air to move around of course. No HDDs however, only SSDs.
Thanks for any input.
