Went from the 11.6 down to the 8.9 and fits like a glove. Distro plate here on Thursday so can try not to ruin everything on the weekend. Tho I imagine i will have to do all runs runs or most of them next month when EK finally releases 3090FE blocks.
Also from that Linus video some time ago
EK-QuantumDelta TEC is a new high-tech water block with a built-in Peltier/Thermoelectric cooler plate. It is powered by Intel® Cryo Cooling Technology, a unique combination of hardware, software, and firmware designed to help unleash elite performance for gamers.

I wonder if we will see an AMD equivalent since EK's is joint w/ Intel and likely EKWB isnt allowed to make one supporting AMD
