Testing Methodology

For testing Mini-ITX and Micro-ATX cases, we use the following standardized testbed in a stock configuration as well as with add-on graphics cards to get a feel for how well the case handles heat and noise. As we've retired our Micro-ATX board from the testbed, Micro-ATX enclosures will be using the Mini-ITX testbed.

Mini-ITX Test Configuration
CPU Intel Core i3-2120
(65W TDP)
Motherboard Zotac Z68ITX-A-E
Graphics Card Intel HD 2000 IGP

Zotac GeForce GTS 450 Eco (dedicated)

ASUS GeForce GTX 560 Ti DCII TOP
Memory 2x2GB Crucial Ballistix Smart Tracer DDR3-1600
Drives Kingston SSDNow V+ 100 64GB SSD
CPU Cooler SilverStone NT07-1156 with Cooler Master ThermalFusion 400
Power Supply SilverStone Strider Plus 1000W 80 Plus Silver

Each case is tested with just the Core i3's integrated graphics as well as with a discrete graphics card. The system is powered on and left idle for fifteen minutes, the thermal and acoustic results recorded, and then stressed by running four threads in Prime95 (in-place large FFTs) on the CPU, and OC Scanner (maximum load) is run when the dedicated GPU is installed. At the end of fiteen minutes, thermal and acoustic results are recorded. If the enclosure has a fan controller, these tests are repeated for each setting. Ambient temperature is also measured after the fifteen idle minutes but before the stress test and used to calculate the final reported results.

We try to maintain an ambient testing temperature of between 22C and 24C. Non-thermal test results aren't going to be directly comparable to the finest decimal point, but should be roughly comparable and give a broader idea of how the enclosure performs.

Thank You!

Before moving on, we'd like to thank the following vendors for providing us with the hardware used in our testbed.

    My TJ08-E is still quite loud, even on the fan's low setting.

    I've done 6 builds with the TJ08-e. For every one of them I have found the front intake fan to be too loud even on the low setting. Plugging into a motherboard with fan speed control helps, but can also cause the front fan to stop spinning at times.

    At home, it is an extremely audible case.

    At work, I can't hear the thing at all even sitting right next to me.

    That is the extent to which ambient noise is a factor. People that call this case quiet may be dealing with higher ambient noise.

    I think after 6 builds I feel pretty confident that I know the typical acoustic character of the TJ08-e

    Also, the drive cage in the TJ08-e is a serious drawback. None the less, it remains my go-to mATX case.

    I've done 4 builds with the TJ08e. I agree they aren't silent, but none of my builds turned out particularly loud either. While ambient noise can be a factor in the perception of what is quiet, I think this may be a difference in standards of quiet. In my most recent build with the TJ08e, the Zalman 9900CNPS is the loudest component. By my standards, the 9900CNPS while not silent, is quiet. The ambient noise environment shouldn't make a difference as to which component is loudest in the build, so if you find the 9900CNPS comfortable, then the TJ08e has the potential to work for you. Just don't expect it to mute louder internal components given it has no acoustic padding.

    I should mention that I forgo the HDD cage all together and mount a single SSD in the bottom bracket that the HDD cage mounts on top of. It makes a difference to airflow. Might make a difference acoustically as well.

    That is exactly what I did with my build, with my secondary HDD up in the 5.25 bay. No sound/temp issues at all.

    I have a TJ-08E, it's nearly silent in my very quiet home environment. I use the "full speed" setting of the switch (so it has enough voltage to start), and then put it down to 400-500 RPM with FanXpert control of my Maximus V Gene. Still plenty of airflow and totally silent.

    I'm pretty sure Dustin's tolerance for noise is a bit higher. I wouldn't call the low setting quiet at all. As for undervolting, you don't need to weld or use a resistor, all you do is the 5v,7v,12v trick of swapping molex wires cables.

    Yes, I have the fan on the low setting, it is still way more audible than a Fractal Design case.

    Meh. I know they had to do it to fit in the drive racks the way they have them but once again this is a micro ATX case that's a scant few inches smaller in one dimension than mid-tower ATX cases. I just don't see the point. If you really want a compact case there *will* be real compromises, tight fits, and less easy assembly than wide open ATX cases. But any 'micro' ATX case that's got a dimension of around 20" is just missing the point of micro ATX.
