Asetek LCLC Takes Liquid Cooling Mainstream

bigwophh writes "Liquid cooling a PC has traditionally been considered an extreme solution, pursued by enthusiasts trying to squeeze every last bit of performance from their systems. In recent years, however, liquid cooling has moved toward the mainstream, as evidenced by the number of manufacturers producing entry-level, all-in-one kits. These kits are usually easy to install and operate, but at the expense of performance. Asetek's aptly named LCLC (Low Cost Liquid Cooling) may resemble other liquid cooling setups, but it offers a number of features that set it apart. For one, the LCLC is a totally sealed system that comes pre-assembled. Secondly, plastic tubing and a non-toxic, non-flammable liquid are used to overcome evaporation issues, eliminating the need to refill the system. And to further simplify the LCLC, its pump and water block are integrated into a single unit. Considering its relative simplicity, silence, and low cost, the Asetek LCLC performs quite well, besting traditional air coolers by a large margin in some tests."

Re:Liquid cooling for datacentres?

[ZeroExistenZ]

i would have thought liquid cooling would make sense for datacentres - instead of huge electricity bills for A/C you could just plumb each rack into the building's water system

There are a few things that come to mind:

• - A datacenter might have different clients renting a cage, owning their own servers you can't enforce the use of watercooling. AC will have to be present and running in any case.
• - Water + electricity is a risk. With tight SLA's, you don't want to fry your server with your extra investments in its redundant failover hardware altogether.
• - Available server hardware isn't typically watercooled. Who's going to convince the client hacking a watercooled system on your most critical hardware is a good decision? For defects, a support contract with the hardware vendor is typical. If you mod it, soak it, you're out of warranty and can't fall back on your external SLA.
• - electricity "bills" aren't an issue, you have so much amps you can run on each cage if you rent you keep under it or you'll have to rent another cage (notice an advantage for the datacenter here?) It's always part of the calculated cost, it's a non-issue really for datacenters or for you when you want to rent a part of the datacenter.

Because air has some undeniable advantages over water:

-Free (both source and disposal)
-Non-conductive
-Non-corrosive
-Lightweight
-Will not undergo phase change under typical or emergency server conditions (think water>steam)
-Cooling air does not need to be kept separate from breathing air, unlike water, which must be kept completely separate from potable water

Imagine the worst-case scenario concerning a coolant failure WRT water vs air:
-Water: flood server room/short-circuit moboard or power backplane/cooling block must be replaced (labor)
-Air: Cause processor to scale down clock speed

I don't think water/oil cooling is ready for mainstream data farm applications quite yet. I also think that future processors will use technology that isn't nearly as hot and wasteful as what we use now, making water cooling a moot point.
