Conclusion: Iterative, But Still Needs Work

With the Define R4, Fractal Design has again produced a solid case that has a lot to offer end users. I'm very fond of case designs like this one and the AZZA Genesis 9000 that give the user a great deal of flexibility in how they want to assemble their system, and I like that Fractal Design lets you optimize for acoustics or for thermal performance. The included three-channel, three-setting fan controller is also greatly appreciated and a marked improvement over the R3.

As a general rule it's good to continually reward improvement and innovation from vendors, and the Define R4 is absolutely a better case than the R3. The problem is that enclosures are one of the places where a lot of innovation is occurring on a regular basis as companies continually revise existing designs and introduce radical new ones in a bid to further optimize system cooling. System cooling is a science that is still miles away from being perfected and probably never will be if for no other reason than that there are simply too many variables to take into account. Engineers have to find the right balance for their product and plant the flag there.

I don't think Fractal Design's engineers were daring enough with the Define R4. This is by no means a bad case, but there are places where technology has improved that Fractal Design could definitely have adopted. For example, SilverStone's Temjin TJ04-E aligns the top fan mounts to the left side of the case in order to improve clearance for increasingly popular 240mm radiators. This is an easy enough change to institute that notably improves the usability of the case. Likewise, switching to hinged side panels allows for clearance for routing the AUX 12V line. Fractal Design could also save some width by introducing cabling channels in the motherboard tray similar to what Corsair did with the Vengeance C70. These aren't changes that are going to dramatically improve the R4, but they're easy ones to implement that make the case more usable without driving up the cost.

Speaking of cost, that's one place where I do think Fractal Design nailed the Define R4. While I wasn't supremely impressed by its thermal performance, I do think it's worth the $10 premium over the NZXT H2, and does a better job acoustically than the $10 pricier Antec P280. $109 is a great price for a case this feature rich and well built, and while the Corsair 550D is a generally better performer, it also has more trouble spots that give me some pause in regards to its longevity. Couple that with an extra $30 on the price tag, and the Define R4 looks a lot better.

Ultimately, I think if I were building a quiet system on a budget for someone, I'd have an awfully hard time finding a better choice than the Define R4. The case absolutely has room for improvement and I wonder if potentially more efficient case fans like SilverStone's AP121 or Corsair's new line wouldn't give us better thermal results, but the $109 price tag is very hard to argue with when you take into account what you get. The R4 isn't a slam dunk, but it's definitely worth your consideration.

    Completely disgree on the door - I have a Fractal Design Define R3, and closing the (foam padded) door makes a HUGE difference to the noise you perceive from the front of the case. Using my phone and a ghetto app, we're talking a few decibels different.

    Just in case I wasn't clear, I mean I absolutely DO want the door. Cleans up the look, massively reduces noise.

    My current case has a door and it too reduces noise a lot. There isn't anything magically about putting a hinge on a solid panel that stops noise, it's the fact that it's a solid panel and no noise doesn't leak through the small openings around the bay ports.

    After reading I may have missed this, but is there any mention of dust filters under the PSU and on the fan mount just in front of it? I can't remember if the R3 had these either. :P

    Regarding the top fan mounts, I must be one of the 5%ers as I love 'em - I currently have the CM Centurion 590, and use both top 140mm mounts at the top, theoretically, with good fans it should help with overclocking on air - heat will always rise more easily than go sideways.

    Apologies, I just went back through the pics and saw that a filter covers both.

    Another question though, would anyone be able to please tell me what the total wattage the fan controller can handle?

    no reviews emphasize that the bottom hard drive cage can be moved back to accommodate a 240mm rad in the front and that bottom cage can be moved anywhere in the case because it has the same bolt pattern as a 120mm fan. that is a substantial difference between the r3 and r4.

    I actually sent fractal a long email about how they can improve apon the r3 and they used 90% of the ideas I gave them, its nice to sea that a company that listens to its customers. one of the many ideas I sent was an option between windowed and non windows versions and a window upgrade kit for the r3

    Great article, Dustin. Really helpful as I've been waiting for the R4 for quite some time now.

    Quick question, in your closing statement, you say:

    "...while the Corsair 550D is a generally better performer, it also has more trouble spots that give me some pause in regards to its longevity"

    Could you elaborate on this point? 550D seems like a great, albeit more expensive, alternative to the R4, but it would be horrible if it wasn't as nicely built.

    Does it have a HDD led?

    going forward, it would help to keep the cpu and gpu fan constant. that way, we can compare the temps and decibal ratings with apples to apples.

    some cases give great cooling to cpu, but are poor for gpu cooling. and a few percentage points for the gpu fan can really throw the db ratings much higher.

    The lack of a hard drive activity indicator makes this case a non-starter for me, which is really unfortunate. Other than that, it looks like a great design.

    Does anyone else feel that this is a critical omission?
