Conclusion

Overall, then, how did the Armor LCS do?

Well, I think it's fair to say could have been better, could have been worse. The problem doesn’t come from the chassis or the case, but a combination of the two. They just struggle to work well together, showing up each others flaws in difference ways, and the water-cooling does well, at the expense of the case, and vice-versa.

There’s a number of reasons why the chassis should be very good at what it does, and indeed, if tested on its own it might well do better (we will put the case into a group review in the near future). Fact is though, with this water-cooling kit fitted, the inside airflow of the Armor LCS shows signs of weakness.

As for the water-cooling kit, it performed well but there are still a couple of issues we had with it.

We did find the floor of the chassis vibrated slightly, mainly due to the pump being directly connected with no noise absorption material inbetween.

Secondly, the mountings for the CPU, whilst very easy, are very much a one-use solution. We would like to see extra sticky pads included in the kit to cover hardware changes during the life of the kit.

Overall, then, the package could be better, on the other hand there are some good points in there when looked at separately, none more-so than the excellent performance from the water-cooling (with respect to the PSU) and the ability of the chassis to devour 9 terabytes of storage.

Let’s just hope Thermaltake takes on board our comments and we see improvements in its all-in-one chassis solutions in the future.

NOt surprised about MB temps, seems like there is a basic design flaw. Radiator at front, means fans are sucking in cold air from the front of the case and blowing it out over the MB! Bound to increase MB temps. Better design would be to have the fans blowing through the radiator and out the front but the downside is that the air the fans blow out is from the inside of the case and therefore pre-heated which will reduce the effectiveness of the radiator.

Only sensible solution is to ducting, fans suck air from the outside of the case through the radiator and then the expelled air is ducted to a suitable exit hole at the back. Downside is that you lose airflow over the MB which can be sorted by including a fan on the side panel.

I also have issues with the back of the case - it looks like the fan at the back and any fan on the PSU (if facing into the case) will be very close creating air turbulence - means more noise and possibly (someone more experienced can confirm) that the fans will be less efficient.

Nice try Thermaltake but flawed.
MB temperature:

I suspect the MB temperature sensor is near the CPU. A typical location would be near the CPU power supply circuit built around the CPU socket itself. This area is a real pain for water cooled systems as it is designed to be cooled by the air flow generated by the CPU cooler. No CPU fan = no active cooling near the CPU.

Take my WC system as an example. The CPU psu circuit on my DFI MB will reach 70 DegC or more during load if I remove my custom temperature controled fan. This is more an example of inconsiderate, with respect to water cooling, MB design than anything else. It certainly destroyed my dreams of a fanless system :mad:

Front fans:

When combined with the right radiator these slow RPM fans are very quiet and excellent at cooling the water loop, they impressed this old cynic. But when it comes to moving lagre volumes of air they are not in the same league your typical 120mm case fan, think of under volting a standard fan to 5 or 6 volts, so the standard rear fan + caddy fan + PSU are probably doing most of the system cooling.

Air off the radiator:

Contrary to popular belief the air coming off the radiator is not all that warm, if it is there is something wrong with the cooling loop. Air off may be up by a typical +3 to +5 DegC, see http://www.xtremesystems.org/forums/showthread.php?t=77260, and probably not of major significance ?
Am I right in thinking that the CPU was a Pentium Extreme Edition 840 in a D955XBK motherboard? Not bad CPU temperatures if I'm right :)
I have the none LCS version of this, got it for £80 on dabs ages ago, 3mm steel all round, weighs a ton, but lives up to the name. They fixed the motherboard temp problems with a huge 250mm fan in the side panel http://www.thermaltake.com/product/Chassis/misc/A2356A2400/a2356.asp. Which you cant buy in Britain for love or money :(

Just wish they sold the liquid cooling kit as an upgrade for the armour too. Despite it's size there isn't much metal left to mount a rad in yourself.
Yep - the LCS did very well, I am trying to get some of their stand alone stuff in to put that through the mill - hopefully it will go just as well :)

As for the side panel, Ill check with Thermaltake on that for you, I figure it would make the world of difference in all honesty.

As for the LCS kit, I think you can buy it separately, in bits, but again, supplier dependent.
