Noise and Thermal Testing, Stock

My frame of reference for the Fractal Design Define R3's internal design may be Corsair's line, but for performance I'm actually more interested in seeing how it compares against Antec's elegantly silent Solo II and NZXT's 90%-of-the-way-there H2. The Solo II may have run hot, but it was also the quietest case we'd tested. Meanwhile, NZXT's enclosure suffered from the design flaw of having no real ventilation for the intake fans to pull air through. That was a concern I had with the R3, but the ventilation is definitely there.

Thermally the R3 isn't as big a winner as we'd really like, but it beats the Solo II and H2, and given its intended purpose a middle-of-the-road thermal performance isn't bad at all. And as I've mentioned before, if you're willing to sacrifice a little silence for more performance, there are plenty of ways to go about doing so.

The R3 winds up ranking among our quietest enclosures tested at both idle and load, beating NZXT's H2 and trading blows with the Antec Solo II while delivering superior thermal performance. If nothing else, Fractal Design has achieved a nice balance here and easily steals the show from the equivalently priced H2.

    Define R3 is an older design, that was what Fractal told answered me when I mentioned the fixed drive cage, which I as well find to be a nuisance.

    For someone who hasn't kept pace with case designs for a long time, could somebody please explain why the PSU now goes at the bottom instead of the top?
  • jrs77 - Friday, November 11, 2011 - link

    The PSU sits in the bottom to make it easier to cool and less noisy. Usually PSUs have a thermal-controlled fan, which then runs faster, if it sucks hot air from within the case. That's why they get mounted on the bottom, where they can suck in fresh air instead, running cooler and more silent. Also, this setup allows for fans being mounted in the top as additional cooling for the CPU, etc.


    The trick with the cable-routing is to rout the cables prior to installing the motherboard, then they'll fit through the grommets easily enough.

    Well, and for cooling and noise... using better and more fans (Scythe S-Flex SFF21D) to drop both, temps and noise-levels does help.
    The biggest plus for the Define R3 is the understatement and the sounddampening at a very low price.

    The allways mentioned CM Silencio doesn't have the top-fan-mounts, which are pretty good for installing a 240mm rad.

    For one thing, it is becoming a heavier and heavier component with increasing power needs, and I don't think 4 screws at the back and just leaving it hanging is a great idea. With it at the top you'd end up with a big shelf splitting up the case to hold it, otherwise.

    Bottom is actually pretty good, and it means you don't have a big mains cable trailing across the back of all your other cables round the back of your machine.

    When will some half way decent Case Mfg eventually realize that when moving the PSU to the bottom, you should really move the Optical bays as well. It doesn't seem that bad in this case because its limited to 2 Optical bays, but every other case with a bottom PSU and 3 / 4 optical bays means that after installing a nice large GPU, you effectively have created a wall between the Fans pushing cool air in at the bottom and the CPU which is now way up at the top of the case.

    The Cooler Master Silencio 550 that someone in the comments mentioned is a PERFECT example of this.
    Look at the side shot with the video card.
    So that tiny slit above the right side of the video card and a whopping 1" gap between the video card and the side panel is where your CPU gets its cool air from?

    Move the damn Optical bays to the bottom so they line up with the PSU (ideally only 2 bays like the R3) and now you have 2 x 120 or 2 x 140 pushing cool air in the front that line up perfectly with the components that need the best cooling. Upper fan cools the RAM and CPU and the lower fan cools the GPU(s).

    and thought it might benefit you, the world.

    Please watch this video on PBS. It is, needless to say - quite interesting, particularly if you are not familiar with fractals.

    Thanks for a great article :)

    I however want to point out that "Methodology" is the study of methods, so unless page 4 is supposed to be teaching us the methods of testing, instead of telling us what methods were used for testing, it should be called "Testing methods", not "Testing Methodology" :)
  • JonnyDough - Saturday, November 12, 2011 - link

    Its no secret that the tech sites I read need better editors. Good catch. :D
  • JarredWalton - Saturday, November 12, 2011 - link

    Nope. Methodology:

    Only 1b suggests methodology as the study of methods. 1a and 3 both support the use of the phrase "Testing Methodology", though "Testing Methods" is equally acceptable.

    I don't really see anything special here.

    Since you mentioned the foam, can you make a an article about foam and how it effects temperatures and noise, if at all? I think the best you can do if you want a quiet PC is choose cool running, quiet hardware. A case does not make or break a silent/cool PC. Of course, that doesn't mean cases are unimportant, they can screw some things up if they are badly designed. But mostly, it's the components inside the case that should be of concern.
