Computex 2017: Lian-Li To Offer a Raw Copper Liquid Cooling Kit

Yes that looks indeed awesome hope it sells good and they release a 360 rad version to!

 

With fans added in you won't even see the copper color. Will just look like everything else.

 

Looks nice.

I wonder when someone will release pure-silver LCS! Just to show off!
(though silver has even slightly better thermal conductivity than copper...)

 

Enjoy Galvanic corrosion with this kit. Nice move from Lian Li. It's not like a lot people know what galvanic corrosion is. Especially those who care for leds and looks and lights...

 

Another smart way of Lian Li to offer less for more.. lol

I do agree that it looks nice but they look quite similar to Airplex series by Aquacomputer.

 

No, it's not about heat dissipation. It's been propven numerous times that the metal plating used in other radiators has negligible effect on heat dissipation. That's why they continue doing it.

 

Why would galvanic corrosion be an issue? It's a AIO cooling solution with a copper heat sink and copper radiator. So long as the fittings, pump and coolant are designed to be compatible it should have no issues.

 

Now that looks interesting, hope we can see some reviews soon?

 

I think he's talking about plating the copper fins of the radiator to prevent oxidation. I didn't think that was metal plating though, just matte paint? At least that's what it looks like on my XS-PC rads.

 

@gx-x
Yeah thats gonna be a big issue, since its always
the uninformed noobs that buy Lianli stuff in the tripple digit price range...
(sarcasm mode: off)
;-)

 

Look more carefully at the images

@fry:

well, I wouldn't call that sarcasm since lian li is overpriced as hell. But, to each his own I guess.

 

If you're referring to the aluminium shroud, one would hope there is some insulation between the soft copper and the aluminium, like rubber or foam to help dampen impacts.
And so long as it stays dry there should be little to no corrosion.

Or am I missing something else entirely?

 

well, shroud, fittings etc. I am NOT claiming though that it WILL have a problem, but I would be careful with mixing metals in water cooling. I used brass radiators since brass is mostly neutral, and brass fittings (all good things that you can get at your local hardware store for dirt cheap ) and cooper for WB, rubber and plexi for closing the WB's top side.

I haven't really seen much of performance difference with using copper radiators compared to any other metal (aluminum, brass), it more about the fin construction and amount + airflow. That being said, if you buy this one for copper looks, be prepared to have it look greenish after few months, perhaps even on the store shelf. It's cleanable but it's a hassle, at least for me it would be.

With all that said, I just reverted to air cooling in the end. Megahalems does pretty much the same job, and no hassle Of course, it doesn't look as nice as water cooling systems, but imho, neither do the AIO systems compared to custom loops.

 

I'd say we're on the same page here. I'd have used a smaller brass shroud and fittings if I was making it but brass is expensive, aluminium is cheap.

Theoretically, the advantage of a copper radiator is it's much higher thermal conductivity (double that of Al). That effectively means that there is less of a temp differential across each fin. (The further away from the heatpipe, the lower the temp in the fin). So with copper, the heat load you are trying to expel is more evenly dispersed across the entire radiator and that equals more surface area being effectively used (or not if you're just going to block off a large chunk of it)
But as you said, radiator design is a bit more complicated than that. Fin count, thickness, operating temp, ambient temp, airflow, etc., etc...
It would be interesting to see the data from a review.

 

@gx-x
but even a "cheap" AIO has a big advantage over any (even the best) air cooler.

if setup as exhaust (i always do it like that, as intake will only marginally lower cpu temp) it dumps the heat outside the case, lowering temps for everything else (gpu/chipset/vrms etc)..

 

I have a 120mm fan behind the another 120mm fan on the back side of megahalems (because I use intel, not AMD) so all the heat is pushed out of the case almost instantly. If that is not enough, I have another 120mm fan on top (above) of the megahalems on the top exhaust hole of the case pulling the remaining hot air up, out of the case. Of course, there is a 120mm fan mounted in front of the megahalems (for push-pull), and 140mm fan in front of the case.
I think you get the picture
Oh yea, they are quiet, you could compare to the pump noise from AIO and the fans from the radiator + the other case vents you would naturally use if you care for keeping things cool.

So yea, pretty much the same thing, well, very similar... Except perhaps my VRM section and RAM a tad more hotter than they would be with AIO but everything is cooled nicely. Except the darned 280x for which there is no cure relly, except water cooling (which would cost as much as the card itself) or just replacing it with newer card.

On top of that, Megahalems cost me ~40$, has mounting for everything, save for maybe Ryzen boards, havent checked that, but I don't really care much for that atm. since I am content with my rig atm. I mentioned the price because decent AIO doesn't cost under 90$ish soo...

I am not bashing on the things, I am just saying that personaly I don't see some special value in them, at least not for me.
