Intel Core i7-9700K All-core Overclocked to 5.30 GHz On Air
Intel's upcoming 8-core/8-thread Core i7-9700K is in the news yet again, this time with a noteworthy overclocking feat of 5.30 GHz with all cores enabled, under air cooling. An enthusiast with access to an i7-9700K chip and an unknown motherboard posted blurrycam pictures of their setup and a CPU-Z screenshot showing 8-core/8-thread config, and 12 MB L3 cache, confirming this is an i7-9700K. The multiplier of this chip is dialed up to 53.0x, which multiplying the untouched base-clock works out to ~5.30 GHz. The core voltage made it to the screenshot - 1.215V.
The most impressive part about this feat is the cooling. A mainstream-looking tower-type cooler is used. Crossing 5.20 GHz with all cores enabled takes current-generation i7-8700K at least AIO liquid coolers. This is probably a testament to the soldered IHS the i7-9700K is equipped with, which improves heat transfer between the die and the IHS. Then again, it could also be the effect of a lack of HyperThreading. At higher overclocked speeds, disabling HTT on current-generation Core i7 processors contributes to stability.

2) the picture is not clear and cant see what cooler it actually is
3) what is the ambient temp?
4) 5.28 is not 5.3
This is as bad as using a chiller to claim top prize. :shadedshu:
CFL is CFL - expect the same voltage to frequency ratios.
This is nothing but a post in a frequency, can be done in a much much lower voltage than needed for any kind of stability test

If you look up the install instruction and look at this pic
Something is odd
Why is the cooling missing from the VRM section, if they used an ordinary tower cooler?
Something is amiss.
There is just no way these chips will do 1.215 at full load with 8 cores at > 5 Ghz. Just. Not. Happening.

It looks to me like the heatsink might only be held down by two screws with an S bracket running between the top left and bottom right screws. It's a lazy way to do it, but probably good enough to keep the heatsink held down on a horizontal board.
