Noise and Thermal Testing, Overclocked

While the Corsair Carbide 400R wasn't particularly exciting at our stock settings, there's always the chance it could acquit itself better under a substantially increased thermal load. Bumping the Intel Core i7-875K in our testbed up to 3.8GHz introduces a huge increase in heat for the enclosure to dissipate; let's see if this produces better results or at least a bigger difference as far as the side intake fan performance is concerned.

Once again, thermal performance is decidedly middle of the road, neither terrible nor stellar, and once again the side intake fans seem to benefit the GeForce GTX 580 more than anything. There's definitely room for improvement here, and once again our unlikely hero at $50 more, the Rosewill Thor v2, continues to offer stellar bang for the buck. It's worth noting that the 400R consistently outperforms its predecessor thermally, though.

In the process, one of the major differences between the 650D's design philosophy and the 400R's surfaces: while the Obsidian series was designed for acoustics first, the 400R is geared toward thermal performance. The result is one of the louder cases we've tested. It's not egregiously loud, but other cases have definitely performed better and more efficiently here.

    Hello!
    I don't understand that passage. I haven't used USB 3.0, yet. Is there some problem with booting from USB3.0 ports? Shouldn't they be backward compatible? :-)
    Thanks for the review! Could you add metric measurements? :-)

    I've had much better luck with side fans being used as exhaust rather than intake. This was true when I tested with my an Antec Three Hundred with a 4890 non reference that exhausts from the back and front, there was a slight advantage with the side fans as exhaust under load. With aftermarket cpu coolers like the Scythe Setsugen 2, the cooling advantage was even greater. CPU and board temps were also lower than with the side fans as intake. Only during idle or cpu only loads did side fans as intake performed a little bit better. Same results even with a pair of 6870's in the Cooler Master 690 II. Another interesting thing I've noticed is that all the fans I've tried are less noisey when pushing through a grill vent rather than trying to suck air through them.

    I guess you have to admire what corsair is doing, even If I don't find the exterior to be particularly sexified. For an attractive, unusual, and generally backassward affair, see the Lian Li PC A05NB. I've been a hopeless shill for it for some time now, but a little Corsair magic on the inside wouldn't hurt (much).

    Hey, another case review so soon? Awesome.

    Can you start reviewing cases like this that actually look nice and not like cheap tacky crap like they were designed by a 12 year old? I know they're very rare but these mythical beasts do exist!

    Well shoot, I was just going to try and review as many bug ugly cases as I possibly could, but since you made the request I'll get right on it!

    I checked out the Lian Li PC A05NB (mentioned by ckryan above). For $90 on Newegg, I'm pretty curious to see how it would compare. The Corsair is not awful, but I still wouldn't put it in my living room. The Lian Li case, however, is undersstated enough to go anywhere.

    Maybe Dustin can request one of the Lian Li's for a showdown - if he isn't already buried in cases to review.

    i just put together one of these for my dad, and it was great to work with. I didn't cut my hand even once!

    also, the usb 3.0 on the front is a huge plus if your popping external drives on/off all the time.

    one thing I did differently was I mounted the PSU upside-down becasue the holes on my seasonic didn't line-up properly otherwise.

    If your PSU fan is on the bottom, like many, you'd want to mount it upside down anyway.

    I have a 650TXV2. The holes on the PS aren't symmetrical, but the holes on the case are symmetrical so it lines up the same way whether it's rightside up or upside down, i.e. I didn't encounter softdrinkviking's problem. I'm not that happy about how it lines up, since the head of one of the screws is sort of holding against the edge of sheet metal instead of going through a hole, but I haven't installed a power supply in years so maybe that's normal.

    Is the power supply in the review picture rightside up or upside down? In the picture I don't see the fan, which suggests rightside up, but the picture may just be too dark. There are other clues that it could be upside down; the position of the cables, and there's no visible label on top.

    The PS would probably run cooler rightside up, but my floor tends to be dusty and I don't like the idea of blowing dust into the PS.

    I currently use a CM 690 with 4 Yate Loon 120mm fans (1 front intake, 1 rear exhaust, 2 on Hyper 212+ push/pull out the back), and 3 Cheap NZXT White 140mm fans (1 bottom intake, 2 top exhaust, NZXT cheap white ones). The case has been banged up during moves and 3 different builds in it. I also redrywalled a room it was in so it's not clean either. I just ordered this 400R and will be ordering a few new fans for it as well. I curently load 54C on my 2500k at 4.5ghz after about an hour of Prime, so I'll test that against the 400R. I am also curious if my 6970 will run cooler if I install side fans on the 400R. The way my side panels work on my 690, I don't have room for side fans. The most important thing to me will probably be noise, I wish I had a way to accurately measure it. My case is very loud, and my fans seem to rattle sometimes.
