Intel Core i9-10900K Stressed, Package Power Reads 235W, Temperatures 93°C

It runs hot, because of the high clock rate and power consumption. Not because the heat spreader is some micro meters thicker.
The thinner chip even enhances the heat conduction.

 

[Vya Domus]

It runs hot and consumes a lot of power because it's on a node that originates from 2014. Let's stop beating around the bush, TSMC went through two full nodes since then. Keep in mind this chip actually benefits from more surface area for dissipation and has lower power density per mm^2 than 7nm chips.

Unfortunately, that would result in all the major coolers needing to be redesigned due to the force that they exert onto the chip. That same force would more than likely break those chips and then Intel would be in an even worse situation.

Oh I didn't realize the force would be an issue... I was thinking just as long as the height from the PCB of the motherboard to the top of the IHS was the same, then it no other issues but I didn't realize the force may need to be adjusted.

Yes. A thinner IHS could be bent if the same amount of force is applied. Coolers would need to be redesigned.

It would, but only in certain situations.

Direct die changes everything as it changes the height. Coolers need to be designed for this, or, as we saw some mfg do, offer a shim kit for delid/bare die cooling.

A thinner IHS with the same package dimensions (height) likely wouldn't be a worry all around. But all other things remaining the same, any cooler with hard stops it won't make a bit if difference.

I don't recall many convex cold plates, though they do exist. Those without hard stops and a convex cold plate could have an issue with a thinner ihs.

I still find it odd that such tests are in any way relevant ...... its the equivalent of testing an SUV's ability to toe tour new Sku-Doo 35 miles to the beach .... by trying to pull a 12,000m pond lous up and over the rockies in the wrong gear .... "I wonder how much heat I can generate by running a CPU under loading it will never be exposed to ?" I'm not really interested in which CPU can draw the most power or to determines if "mines bigger", only how it does the job I'm asking it to do.

No it is not odd. Only because you are not running computationally demanding programs, does not mean that is true for everyone.
I have several applications, that run under full load on all threads of the cpu.

Hi guys,
I am a new member of your forum. I built a new pc, with
Main board maximus hero xii
Cpu 10900k,
Graphic 3090 msi suprim x oc,
Ram 32 g 3600 mhz,
Ssd samsung 980p, and
Power 1200w cooler master platinum. The AIO is 240 deep cool castle. At unload my cpu temp is 32, 40, When I started to do 3D max rendering, all of a sudden the CPU temp goes 99, and usage jumped from 2% to 100%. I am very worry about the CPU temp, does it mean I cannot do rendering with my CPU not at all? Is it a normal temp for such activity. I scared then I stopped the rendering after 3 seconds. Mother board also indicate a red light.
What should I do. Please help me.

99 is too hot... yes. You're probably throttling.

I assume this could is stock? Confirm your aio is working...

How can I be sure AIO is working properly.I think it is working, becasue when cpu temo want go up, the speed fan increases. But for that very small rendering it was very strange.

A 240mm AIO (ca. 230W TDP) could be too weak for the i9-10900K on full load.
I have a 120mm AIO (200W TDP) for my i9-9900K and I have to lower the power limits, to prevent heating it up to 100°C.
I have set PL2 to 165W and 56 seconds and PL1 to 125W. With this settings I have around 90°C under full load.
For the i9-9900K and the i9-10900K I recommend a 360mm AIO water cooler (300W TDP).
And check, that the cpu block is fastened correctly and that the plastic foil is removed.
