This would have been a poor passive cooler, low-loads or otherwise. The fins are too densely packed, the fans overlap much of the entry and exit surface, and airflow can only go in one direction. These are all good things for an active cooler, but passive cooling is a different challenge.
Was thinking this too. Individual chiplets/dies will dump their heat most effectively straight up through the IHS, though it does "spread" the heat somewhat it shouldn't be a huge issue, I just wonder why no one used a Vapor chamber on TR for air-cooling. Would be the best way of getting that heat off the MCM.
AMD has already launched 64 Core Epyc CPUs and so its not a surprise to find it on marketing material of a CPU cooler. Whats surprising is the sentence directly implies 64 core sTR CPU coming in weeks time.

I'm sure the LEDs do all the magic :).airdrifting - Friday, October 18, 2019 - link
Directly heatpipe contact on a giant chip like Threadripper? Wow just wow...AshlayW - Friday, October 18, 2019 - link

Would be the best way of getting that heat off the MCM.Or, just use a liquid cooler.

You can always mod the vapor chamber on if you really want.https://www.aliexpress.com/item/32590545969.html?s...

$70 is a fantastic price for this class of cooler.nandnandnand - Saturday, October 19, 2019 - link
Is AnandTech not allowed to quote the text on the back of the box?You know, the part that says "64-core CPUs".

My understanding is that **push-pull** coolers typically add little, if any, efficiencies.
That is, however, a good-looking unit at a reasonable price.
Look forward to reviews ...

I wonder how much crossover there is between the TR market and the gamer RGB market.
