Noise and Thermal Testing
In a bid to focus on providing only useful information and keeping things clean, simple, and to the point, I've culled idle thermal test results from this review (and will from reviews going forward). Idle thermals are borderline irrelevant, and only important when they're comically high; at idle, the most important statistic is noise.
As I mentioned on the Testing Methodology page, due to retiring the micro-ATX board from the primary testbed, micro-ATX cases will now be tested with the mini-ITX testbed. That means that I can't compare the Fractal Design Define Mini directly against the SilverStone SG09 and the Rosewill Line-M. As it turns out, that may not be as big of an issue as it first appears.
The Fractal Design Define Mini was tested with the included fan controller at its lowest and highest settings. Ambient temperature ranged between 22C and 25C during testing.
Already things aren't looking that great for the Define Mini. Changing the fan setting doesn't do a whole lot fo the CPU, but the system just isn't very good at keeping the CPU cool. In Fractal Design's defense, this case looks better suited to a tower-style cooler, but as you'll see later, the problem may not be simply a cooler not being right for the case.
While the highest fan setting is definitely louder than the lowest, it's not tremendously slow, and it's still below the 30dB floor of our sound meter. If nothing else, in our barebones stock configuration, the Define Mini is very quiet.
Ordinarily adding a dedicated graphics card will bump the CPU temperatures up a couple of degrees (sometimes it actually can reduce them a little since the IGP is no longer in use). Not so, here. The GTS 450, typically a model citizen, just makes a bad situation worse. And despite having direct airflow from the front intake, it still runs hotter than the bulk of the cases tested.
Noise levels continue to be low, but they can't really make up for the consistently poor performance of the stock fans in the Define Mini. Bumping the graphics card up to a bigger monster like the GTX 560 Ti does seem to help at least a little, though.
Comparative performance improves some and the two fan settings start to really separate. While not strictly comparable to results from the main testbed (which has an extra 30W of CPU heat to dissipate alongside the 560 Ti), the graphics card's performance is now at least competitive. CPU thermals continue to underwhelm, though, with the highest fan setting being required to produce decent results.
The Define Mini does a strong job of proving its worth once the noise results come in, though. Things are running pretty warm, but they're reasonably quiet, too. At idle the system remains inaudible, while load noise is fairly low. This is one of those instances where a higher case fan speed can actually produce lower noise, though, as the graphics card's fans don't need to spin as fast to move cool air over the GPU.

My TJ08-E is still quite loud, even on the fan's low setting.flipmode - Monday, April 22, 2013 - link
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.JPForums - Monday, April 22, 2013 - link
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.JPForums - Monday, April 22, 2013 - link
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.cragAT - Tuesday, April 23, 2013 - link
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.madwolfa - Monday, April 22, 2013 - link
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.EnzoFX - Monday, April 22, 2013 - link
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.smellykaka - Tuesday, April 23, 2013 - link
Yes, I have the fan on the low setting, it is still way more audible than a Fractal Design case.MadMan007 - Monday, April 22, 2013 - link
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.
