I chose the F (no onboard graphics - I have a graphics card) and non-K (can’t overclock) version to save a few quid.
I’m using it in a quiet PC build (not fully silent) and I hope the 65W rating will keep it cooler/quieter than higher rated processors...
The processor is rated 3GHz but actually runs at 4.5GHz with turbo boost left on. I’m at about 35 degrees idle and up to 65 during peak load.
