At Stock All-Core Boost, i9-11900KF "Rocket Lake" Hits 98°C with 360mm AIO CLC Under Stress
Intel's 11th Gen Core "Rocket Lake-S" processor is shaping up to be one hot chip. Enthusiasts on Chinese tech forum ChipHell with access to a Core i9-11900KF sample report, that when stressed at [apparently] stock settings, in which the processor hits its all-core boost frequency of 4.80 GHz, even a 360 mm all-in-one liquid CPU cooler struggles to keep the chip from hitting 100 °C, with core temperatures reaching 98 °C. The i9-11900KF comes with a disabled iGPU, which means all of its heat is generated by the core and uncore components of the GPU. AIDA64 was used, to apply multi-threaded stress on the processor (the burn-in test), while CPU-Z reports a core voltage of 1.401 V, it's not known whether this is a manual setting, the chip's VID, or whether the motherboard is trying to stabilize the 4.80 GHz clocks.

Edit: Not that I would bet much against this either!
Said it before this forum needs a Rumors section :-)
Indeed what ever aio was used needs to be rma'ed lol
10900k does all core 5.3 at 80c max so I'd say op is fake news at best.
my entire computer (4 HD's 1SSD, gtx 1070 (4 displays at the same time), ryzen 7 3700x and 10 rgb fans) pulls 350W (total) under full load. Intel bout to ruin the green new deal all by themselves.
Probably the most embarrassing release of Intel ever...
Other than power efficiency, 11900K at 4.8GHz should be plenty competitive with Zen3.
ouch
Also did everyone just forget that modern chips run right up under their thermal limit to achieve a longer more stable boost duration, simply because the title says Intel? If the chip has thermal management to sustain 98C indefinitely so that performance doesn't just fall off a cliff at 120 seconds or so, that's slightly impressive.
