Of note, there is an "optimal" orientation for the coldplate: You'd want the microfins long-ways across the widest part of the CPU IHS, as that'd ensure that the most thermal mass sits directly over the dies. We also run into concerns where the coldplate's most effective cooling area sits atop nothing of import -- the center of Threadripper isn't a die, it's spacing between dies. Typically, that center area would also be the center of thermal activity on a traditional single-die desktop CPU. That's why the cooling mass is focused over the center like it is, but that design doesn't apply well to Threadripper. Instead, we have two peripheral hotspots toward the outer perimeter of the coldplate. Although these Asetek CLCs may be adequate for cooling Threadripper, if only because of brute force, we also believe they are less efficient than they could be. There's a lot of room for other manufacturers to improve on this, given the unique parameters of Threadripper. And to be clear, this isn't a fault of AMD or of the cooler makers -- Threadripper and the coolers can exist independently as well-designed products, but that doesn't mean they can exist optimally together. But then again, we'll review it eventually. Can't carry this too far.
Those observations do provide a foundation, though: Here's a look at the die location for Threadripper:

*grumpy noises* i'll go make myself another cup of coffee. I so forgot about the NDA thing lol.
I know the thermal paste was pre-applied. Not sure what you're addressing exactly?
Sorry I didn't understand your question.
Ok that is what I thought for enterprise, but wasn't sure. Thanks.Originally Posted by Olivon

Cooling on servers is based on heavy air flow from front and go through the heatsinks.
Even Itanium CPU are cooled like that and it's not a problem.
Of course, you need heavy clim to cool the room. Or, like we have at my job is an InRow system who tramsform the servers heat in cold outside the racks. It's called hot aisle / cold aisle sytem.
