One of the most important things when assembling a new PC is knowing the temperature of the various components and their power consumption, in order to choose the best possible case, power supply and cooling system.
The high temperature reached by the Intel Core i9-11900KF
Thanks to an image posted on the Chinese Chiphell forum, we were able to know that the Intel Core i9-11900KF heats up to 98 ° C. KF models are those in which the integrated Intel Xe GPU is inactive but have the same specifications that models with it are active.
Regarding consumption, despite the fact that Intel quotes the processor with a TDP of 125 W, the reality is that it can reach up to 250.83 W thanks to the Intel PL2. Which is similar to the previous generation Intel Core Comet Lake-S, but at the moment it is not known when the processor reaches this level of consumption and heat, but the previous generation reached 250W in periods increase to 56 seconds.
The surprising thing is that said consumption and temperature are obtained using an AiO 360 radiator, therefore the temperature levels obtained do not correspond to a traditional configuration.
In the picture you can see how CPU-Z already correctly detects the new Intel processor after its last update, but it incorrectly gives the voltage as it puts it at 1.401 when running the test, but that filtered out the information says that AIDA64 gives the correct data, i.e. 1325 V.
Either way, the fact that this CPU hits 98 ° C using liquid cooling isn’t good news, especially considering that its prices and those of the Z590 cards won’t be particularly cheap. If to this we have to add a case with a complex cooling system, it seems that mounting a gaming PC with an Intel Core based on the Rocket Lake-S architecture will not be cheap.
Intel Rocket Lake-S, a bad decision from Intel?
In view of the evolution of the new generation of Intel Core, one wonders what are the reasons that led Intel to launch Rocket Lake-S and not to bet on a desktop version of Tiger Lake, which has a better report power / power consumption thanks to its Willow Cove cores, which are between 10-20% faster and under the Super Fin process of 10nm.
Alder Lake’s launch date announcement a few days ago, along with news like this at hand, makes us wonder if it was a good decision for Intel to launch these processors on the market. Of course, they represent a performance leap over Rocket Lake-S, but in terms of temperature and consumption, they fall short of expectations.
The temperature and consumption specifications of the Rocket Lake-S like the i9-11900KF may come from sharing the same chipset as its predecessor, but mostly the same socket as the LGA1200. This influences the power consumption specifications and the way power is distributed to transformers.
