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.

The cooler used is this one, or am i wrong?
I have one of those
www.hw4all.com/antec-a30-a40-pro-c40-c400-cpu-coolers/
Anyway, it still looks slightly different to the Antec cooler.
And as long as that market exists, no company woiuld be foolish enough to ignore them. Actually, since Sandy Bridge (4.8 GHz), I never had an OC determined by temps ... always hit the voltage wall (1.4 in BIOS / 1.5 observed) before heat was an issue. But I skipped Ivy Bridge ... that was the only series where I thought delidding was warranted.
But then again it's Intel and hence must be capable to working on by holy spirit...:p Maybe that PC crashed before they could actually take and save screen capture?
I mean it's such demanding operation that you can't expect overclocked PC to survive stress of it...
*** but is that really the case, as Gamers Nexus has shown before, using a multi-Meter and actually checking / testing the voltage at the CPU socket on the Pin for supplying all the voltage to the CPU could actually be Lower!!! ....
or much much higher than actually being reported !!!!! Not only in the BIOS, But also almost any system monitoring program or application ?? also depends on the LLC, AKA ( Load-Line Calibration ) settings!!!
the actual voltage in CPU-Z ( as reported @ 1.215 V) could actually be 1.025 V or even 1.425V wich could possibly be way too high for a particular CPU and it may run for a long time, it may only run a few hours, or it may even just fail on immediately
or internal cpu components could fail over time, like the iGPU, or Memory controllers, the CPU NB ( aka Chipset in CPU - also known as the memory controller as well)
im 34 yrs old now ! and have been in PC building for the hardware/gaming PC's scence i was 8 yrs old ( THANKS ADD / ADHD -LOL- ) so iv been building / upgrading and repairing and even overclocking for a couple decades.. 2 decades, a minimum of 20 yrs. , ...
26/27+ yrs total i believe, so 30 would be 3 decades_ but 3-4 more yrs and almost 3 decades of working with computers/ mostly hardware interest
all the way back scence 1992/93 back in the 3x86 - 4x86 and pentium processor days, even the OLD Intel Pentium Overdrive CPUS, any one even remember those lol, damn i miss those old days..
