Tech giant Intel experimenting with on-chip liquid cooling, a move that brings both apprehension and relief, knowing the delicacy of integrating liquids near costly electronic components.
In the realm of tech advancements that still doesn't make me roll my eyes or induce an unsettling feeling of impending doom, there's the exciting buzz surrounding the potential incorporation of in-package liquid cooling into the PC gaming market. This trendy computing enhancement seems to be currently captivating the industry, and here's hoping it'll eventually find its way into our gaming rigs.
Just a few days ago, a popular YouTuber whipped up a DIY version of something similar, and now Intel has stepped up their game, presenting a water cooler that sits atop the CPU package instead of an IHS, pumping fluid through to, you guessed it, cool the blasted chip. The super-slim cooling solution features minute copper microchannels that guide the coolant and offer targeted thermal relief where it's needed most.
Intel showcased these experimental in-package cooling solutions at their ongoing Foundry Direct Connect event. These prototypes cater to both LGA (land grid array) and BGA (ball grid array) surface mount chips, with Intel presenting such coolers for Core Ultra as well asXeon CPUs.
The cooling power on offer here can handle up to 1,000W of heat, which is a bit more Xeon-level than Core Ultra-level, but it's that positive outlook towards AI expenditures that makes me cautiously optimistic. The server industry is getting a hefty cash injection, and you can bet your bottom pennies that developments like this will spin off from that. With a dash of luck, a small fraction of that will eventually end up in our gaming-focused wallets.
Now, it's important to note that Intel's been tinkering with this tech for quite some time. Reports suggest that some of the research dates back to 2005. It's fascinating that this technology is finally coming to light at the same time other third-party solutions are surfacing.
A week ago I was chattering about a cooler from EmCool that's meant to attach to a delidded CPU, with liquid flowing through micro-pin fins to maintain a steady temperature. Not to be outdone, a DIY version was also buzzing about, featuring machined channels for liquid cooling to flow directly into the IHS.
One key advantage of Intel's cooling tech here seems to be the ability to direct liquid flow to hot spots. Given recent thermal imaging scans revealing hot spots in certain RTX 50-series graphics cards, it's safe to say we could all benefit from such a targeted cooling system.
Intel claims a reported 20% improvement in cooling efficiency, which is music to my ears. Anything that spares me the hassle of delidding my CPU and doing the mod myself is a winner in my book.
