Asetek has introduced one of the industry’s first closed-loop liquid cooling solutions specifically designed for Intel’s 28-core Xeon W-3175X processor for extreme workstations. The 690LX-PN cooler can dissipate up to 500 W of heat and therefore enables owners to overclock the CPU beyond its stock frequency.

Being a leading supplier of liquid cooling solutions for datacenter processors, it was a natural fit for Asetek to develop a cooler for Intel’s Xeon W-3175X processor in LGA-3647 packaging. The 690LX-PN is comprised of Asetek’s proprietary water block featuring its 6th Gen pump that is attached to a 360-mm copper radiator equipped with three strong 120-mm fans. The copper cold plate covers the entire processor package and is only compatible with this platform.

Asetek has not yet listed all the dimensions of the 690LX-PN AIO LCS, but it looks like the cooling solution is compatible with any large PC chassis that has mounting holes for a 360-mm radiator.

The Asetek 690LX-PN cooler is available directly from the company at for $399. The device is covered by a two-year warranty.

At present, Asetek’s 690LX-PN liquid cooling system is the only cooler that Intel has certified for its unlocked 28-core Xeon W-3175X processor for extreme workstations. Meanwhile, since 500 W is a rather regular TDP for AIO LCSes with a 360-mm radiator, it is possible that other makers of cooling systems will offer something for the CPU as well.

    "the BOM between a good baseplate and a crappy one is maybe a dollar"

    Your estimate is way, way off for volume production.

    ASETEK is the bomb.

    Hope they're sending Ian a sample to try out on the sample machine Intel sent.

    Did you not bother reading said article?

    Yes but for some reason I thought it'd come with a 500W air cooler and that he waiting to test with this water cooler. Now I re-read it I see he was waiting to test with a *better* water cooler that had been sent, but not arrived quite in time. I think I got thrown off by this paragraph:
    "Intel sent an EKWB Phoenix cooler which is rated for much higher power consumption, but arrived too late for our testing. We’re planning on doing an overclocking review, so this should help. But what our results show is that when Intel showed that 5.0 GHz demonstration using a water chiller they really did need it." -

    I guess a water *chiller* is different to a water *cooler* (because it doesn't actively chill).

    That very same cooler is in the Xeon box sent to Ian. Check the images and the article text, but for a quick TL;DR, the huge cooler isn't enough for aggressive OC.

    Will this cooler work with LGA3647 Platinum 8176 CPU or just the 28-core Xeon W-3175X?
