Chipzilla shows off CPU watercooling slab

by on27 May 2025


Prototype microchannel cooler targets 1,000W heat 

Troubled Chipzilla is playing with water again, this time showing off an in-package liquid cooler at its Foundry Direct Connect shindig. Rather than slapping a chunky block on top of an IHS, this design squirts coolant directly over the silicon, using copper microchannels to hit only the bits that get seriously toasty.

It’s a slick-looking solution that currently exists as a prototype for both LGA and BGA packages, and it's being shown cooling Core Ultra and Xeon CPUs. It's the kind of cooling that seems absurd until you realise it’s built to deal with thermal loads up to 1,000W. That’s not just overkill for gamers, it’s proper server-level madness, which makes sense given this sort of tech is riding the AI wave currently flooding the data centre scene with cash and research grants.

German site HardwareLuxx reckons Intel’s been poking at this since 2005. But now, with AI hype machines running hot and YouTubers hacking up their own delid-and-liquid Frankenchips, Chipzilla finally seems ready to let the public see its homework.

It’s not even the only game in town. Just last week, EmCool showed off a commercial liquid cooler that mates directly with a delidded CPU. Another DIY modder took things further, machining fluid channels straight into the IHS itself. So this space is heating up. 

What Intel is offering though is precision. By routing coolant directly to the chip’s hot spots, it can avoid wasting effort chilling bits that don’t matter. That’s handy, especially given recent thermals from RTX 50-series cards show modern silicon tends to cook in patches rather than evenly across the die.

Chipzilla is claiming a 20 per cent cooling performance boost with this setup. That’s enough to tempt anyone who’s ever pondered cracking open their CPU just to shut it up. Assuming, of course, the tech eventually trickles down from Xeons to something vaguely consumer-shaped.
