Intel's i9-11900KF reportedly runs very hot - 98 degrees on a 360mm CLC

That's a lot of heat for an 8-core CPU

Intel's i9-11900KF reportedly runs very hot - 98 degrees on a 360mm CLC 

According to a post from Chiphell, (thanks @9550pro) we have seen how hot Intel's upcoming i9-11900KF could get under load. In their post, Chiphell users Enthusiastic Citizen reported that Intel's Rocket Lake i9-11900KF could reach temperatures of 98 degrees under load with an "entry 360 AIO".

If this report is legitimate, it looks like Intel's 11th Generation processors will run very hot, even when using expensive all-in-one liquid coolers. The poster also stated that the CPU was running at 1.325V and was using AVX3, also known as AXV-512. The CPU was also reported as consuming 250 watts of power. 

With this CPU using AVX-512 during this test, it is worth noting that this workload is much harsher than almost anything that mainstream users will be doing. On Intel's existing AVX-512 compatible processors, utilising the feature is a quick way to see your temperatures skyrocket. If Intel's Skylake-X and Cascade Lake-X series processors are anything to go by, AXV-512 will generate a lot of heat on Intel's 11th Generation Rocket Lake processors. Non-AVX-512 workloads will be a lot easier to manage thermally.

Even if this leak is legitimate, it is worth remembering that AVX-512 will only be utilised in a minority of today's workloads. Beyond that, we do not know what make or model of liquid cooler was used for this test. For all, we know it was a budget-oriented 360mm cooler, many of which can deliver less coming performance than high quality 240mm liquid coolers. We will need to wait for reviews before we can conclude that Rocket Lake runs hot.

LOL...


No wonder Intel are championing those TEC coolers by EK and Coolermaster.Quote

The slightest mishap with your AIO and it could be reaching boiling point!

imagine your fans stop spinning and you dont notice :OQuote

I wouldn't expect anything less when running an AVX512 workload, That is intense, What about when running cinebench or normal gaming ? That is what matters, Not AVX512, I bet the temps will be much lower.Quote

But if you think about it, if the competitor (5900X for example) in AVX512 hits 80C with a Noctua D15, that means the 5900X's cinebench/gaming numbers will also be significantly lower than the 11900K. AVX512 is not realistic, but if the temperatures are absurdly high there, they'll still be high for realistic loads. While if the 5900X which outperforms hits high numbers (not absurdly high) in AVX512, it'll hit low numbers for realistic use cases. It doesn't scale linearly as you decrease the load, but you get what I'm saying. You take the worst possible scenario and scale it down, which will still mean the 11900K is an inefficient CPU.Quote
