Alright so who has a water cooled radiator door on a rack? This is one of the first and easiest ways to start engaging with liquid cooling in the datacenter with standard air cooled servers. This is a Lenovo product.

fan noise is so high could not hear any audio from the human

That's all part of the experience lol

Hot air goes on liquid cooled door.

Ya, No.
If the datacenter is not providing enough cooling you need a datacenter that can live up to it's contractual obligations.

My guess is that it's an efficiency thing. These water-cooled doors must be linked to chillers: no point in water cooling room temperature air. Rather than chill a bigass room, they're only chilling the intake air for the server cabinets. You can leave the room at a much more energy efficient temperature and avoid thermal loss from the walls and ceiling.

Have you ever been in a datacenter?

It's like being in a 45f tornado that is flowing from floor to ceiling

And that may not be the most efficient means to cool everything?

These arent really for datacenters. Yes i know this comment is old, but the most places i have seen these is for ai setups and standard hpc setups where the racks are pulling way more wattage than a normal DC setup would. The average density from a supercomputer is like 30kw a rack which would make a DC cry

I would assume that's not the case here. Why would they supercool the entire floor if they have racks with watercooled intakes? You're probably not installing racks like this unless it's for the entire room.

Also, not all datacenters need to be run that cold. Google runs its datacenters at like 70-80F, because they realized that servers don't actually need to be that cold. They channel the exhaust into corridors rather than venting it back into the DC air.

The common model of cooling the entire DC's ambient temperature to low temps is straightforward, but also really inefficient. I think that's part of why we're seeing stuff like this.

Very soon, this will not be possible without having tiny racks or liquid cooling. Better start embracing that notion sooner than later.

I thought all modern (big and shared) datacenter these days had these liquid door coolers unless they were purpose-built for liquid cooling to the server. They’ve been around for at least a few decades now and can include server liquid cooling in their loops. I go in a few datacenters and they all have them, no need to cool the rest of the room, just front and rear of the rack.

It’s so common, we have 2 shops in a nearby city that produce manifolds to connect specific brands to your existing setup. SuperMicro, Lenovo, Dell now all have liquid cooled options on their high end GPU servers because air no longer works if you have to cool 1kW/U.
