I was running the cache on my at 1:1, and the heat should actually be fine, as you should never use P95 with overclocked Haswell and Broadwell CPU, and my 4790K is just kept from throttling by my Seidon 120V (and that should be solved by deliding, replacing the current and from what I can tell poorly applied TIM with CLU, and using MX-4 on the IHS). I have no intentions of running it any faster than 4.7 CPU / 4.6 cache because it's just a backup rig. It was so stable at 4.8 that I wouldn't doubt that it would run a sketchy 4.9 to 5.0 with adequate cooling. ![]() It was also perfectly stable at 4.8 CPU / 4.6 cache, but heat was just too much for the small 240mm rad. To my surprise it runs all day long at 4.7 GHz with 1.297v with only two cores peaking in the mid 70's Celsius. ![]() I didn't expect much out of the 4790k because I've never had any interest in one. ![]() I just recently installed a 4790k into an backup computer along with a small water loop (240mm rad) to keep it cool. Most of them seem to hit at least 4.6GHz, with others being capable of 4.8 at a safe voltage (like mine), however there are always the shitty exceptions that overclock badly, and I've found that at 4.8GHz a 4790K throws out a fair bit of heat (though mine needs a delid as it runs a lot hotter at stock with my AIO than it should be, and far hotter than my i5 4440 which idles at ambient, not at a delta of 20 oC).
