Noise and Thermal Testing, Dedicated GPU

Cooler Master advertises the Elite 120 Advanced as being able to support the biggest, most powerful video cards on the market, and on one point that's true: there's certainly space inside the enclosure for them. The problem lies in keeping them cool; given how small a Mini-ITX case is, a large video card will essentially create its own thermal zone by virtue of its sheer size in relation to the rest of the chassis, so video cards are going to depend almost entirely on the side ventilation of the Elite 120 to feed their fans.

To test Cooler Master's claims, though, I ran the Elite 120 with both our usual Mini-ITX card, the Zotac GeForce GTS 450 Eco, and with our bigger ASUS GeForce GTX 560 Ti from our ATX/Micro-ATX testbed.

In the most technical sense, the Elite 120 certainly supports higher performance graphics cards, but I'd really hesitate to put anything faster than the GTX 560 Ti in this case. The sheer length of it seems to trap heat inside the drive cage, ramping up the temperature of our SSD. Our CPU also has a harder time staying cool due to the heat radiating off of the back of the video card.

This is the first time I've seen the Mini-ITX testbed's cooler pushed to its limit. You can fit a GTX 560 Ti in the case, but it will overwhelm the cooling system. If you want a card like that in a Mini-ITX build you're going to have to move up to a BitFenix Prodigy.

Noise Levels with dGPU

With all the fans cranking away as hard as they can the Elite 120's noise profile doesn't improve, either. At the risk of sounding like a broken record, anything more than a PCIe-slot powered video card is probably going to push this case too hard.

    The case looks decent in a htpc rack.

    problem is it is noisy.

    I use a sapphire hd 6670 ultimate video card. it is passive. = silent

    I use a seasonic 400 watt fanless psu = silent

    i use an asrock itx board = not cheap

    i use an intel i5 2500t cpu = low power runs cool

    i use an ssd = silent

    i use a 500gb 2.5 inch 5400 rpm hitachi = very quiet

    i use a samsung blu ray drive.

    this would have been a nice htpc machine in a rack ,but the stock fans are noisy.

    I need to play with it some more.

    the small 80 mm fan on one side is the problem very noisy.

    also using a low cpu cooler heatsink is a must.

    the cpu cooler blows right into the psu.

    I think if i had a psu with a fan and let it pull hot air out of the machine

    i could keep the machine cooler. maybe then i can lower the fan speed on the small fan.

    as for ugly the cooler master label is flat out not needed and is truly the worst part of its looks.

    Why an i-5 and an external graphics card for an HTPC? A Celeron or I3 T would be more than good enough for for an HTPC with a GPU. Or you could use an Ivy-Bridge i5 with the onboard GPU for lower cost and thermals. The only good reason to have an i5 and a GPU would be gaming. Also you might want to consider dumping the HD and using a NAS for media storage. That can be in another room and you can put as many big cheap drives as you want on one. Even something like PoGo plug will work for serving media.

    I've built 2 mini-itx systems. I used one of the older Lian cases. The case uses a full sized ATX power supply; but I only have used modular cable-ling. The last build used a all-in-one water cooler. Is there enough room to put a water cooler, e.g. Corsar H60 or Antec 620. Water coolers also fix a problem that low-profile fans run into with all of the cables (usual power supplies have too long of cables) a fan can hit the cable and stop cooling. No such problem with the water cooler.

    Water cooling in this case would require some cutting and would almost certainly require you to mount both the fan and the radiator on top of the case.
    It would be possible to snake the coolant lines between the PSU and the GPU, but the length of the coolant lines might be an issue.

    All in all, you'd be better served with a different case.

    Whilst I agree a different case would be better I think this case is capable of supporting water cooling, just a little imagination is needed. Remove the drive cage and use a slim line optical drive with room for one or 2 2.5 drives beneath it (or drop the optical drive). Take a 120mm radiator (140 may fit) and turn it 90 degrees so barbs are on the side. Use the new swiftech apogee drive and you have a watercooling system that can cope with the CPU and (probably) a low heat GPU. You can also use the water cooling hole at the back as a fill port so not entirely wasted.

    Personally I think it is all a bit too cramped for that but it is certainly plausible

    on itxgamer.com forums someone posted one of these: http://www.amazon.co.uk/accommodate-supply-Optical...

    is there any chance of you testing it in near future?
    it's roughly the same size, same price... only with different (better?) layout

    I have owned two mini ITX cases that had SFX power supplies. Both I found too noisy, while an entry level 300 ATX one can be almost completely quiet. I now have a Lian Li one and very happy with performance and noise level.

    Yes it's a problem of trying to cram too much power dissipation into too small a space. There's only so much you can do with forced airflow before the fans get too noisy. Using standard modular components makes things worse as they aren't going to be tailored to match the case's layout and airflow (the author touched on this a bit talking about the chore of trying to cram ridiculously long PSU cables designed for a tower case into a mini-ITX case.)

    Well, when you try to remove all the heat dissipated in a computer using 300-400 watts with a single 92mm fan (what the Shuttle SZ77R5 uses, because that's as big as they could possibly fit on the rear), you're going to have to spin that fan pretty fast to exhaust all that heat. And when you spin a fan at 3000+ RPM, it's going to get loud no matter how fancy your fan gets.

    I think they could have designed the SZ77R5 (and other similar SFF cases) a bit differently, though. For clarification, in the SZ77R5, the CPU's cooler is just a plate attached to heatpipes that connect to a heatsink that mounts to the rear of the case, and a single 92mm fan blows air through that, acting as both a CPU and case fan. If, instead, a 92mm fan was placed on the top of the case, a 120mm or even larger fan could be used, which would allow the same amount of air to be moved while spinning at a much lower speed.

    Get rid of the massive logo on the front. I'm not in the market to advertise for the companies I buy from.

    If people want the Cooler Master logo, give them a sticker.
