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.

    All copper? Nice. Now why can't I find an all copper AIO for the ThreadRipper? I don't want to have to deal with corrosion, but everything seems to have an aluminum radiator.

    All copper and no RGBs, fuck yeah! Asetek needs to sell a version of this for all the AIO form factors.

    Probably because ThreadRipper is not a house heater, but a processor and doesn't need a $400, all copper, cooling device to work at defaults without throttling.

    the statement was: to work at defaults without throttling
  • nathanddrews - Thursday, January 31, 2019 - link

    Throttling is its designed default, so that's a false starting point. The reality is that IF you want your 2990WX to perform closer to the W3175X, then you must OC it and must also therefore accept higher thermal output and power consumption. At "default" values, the 2990WX is significantly slower across nearly every test:

    On the benchmarks you linked there the ones that matter for the use cases for either of these CPUs (multithreaded rendering like blender cinebench etc) the Intel part is minorly faster. When you factor just the CPU price difference (not even counting the rest of the platform) the Intel Xeon makes no sense. If you want to talk gaming performance then the 9900k walks all over it. I just don’t see a case where this CPU is the logical choice.

    A cooler for a 500w or more CPU, does it come with a free egg frying attachment?
  • JlHADJOE - Thursday, January 31, 2019 - link

    Add a reservoir to the loop before the radiator and use it to soft-boil eggs?

    I've often wondered why Coolers and especially AIO's where made so crappy by design.
    If you've played around with making your own baseplate, you know you need a next to perfect copper or silver baseplate and a nice balance between flow and coolant contact surface.
    the BOM between a good baseplate and a crappy one is maybe a dollar or so lets say 10 dollar for a silver baseplate. Same thing with the radiator.
    A radiator may be a kilo if you made one from copper. That's just 5 dollar.
    I understand you need affordable products. But why does nobody jumps in the gap and make a great one for 50 dollar more?
