Noise and Thermal Testing, Overclocked

Going into overclocked testing after seeing the results from the stock tests didn't leave me with much confidence in the Corsair Vengeance C70. Performance is basically on par with the much quieter Obsidian 550D, while Antec's Eleven Hundred is running away with the crown at as much as $40 cheaper. As you'll see, overclocking didn't treat the C70 much better.

At this point Corsair's own Obsidian 550D is basically running away from the C70 at virtually every metric. I expected at least GPU temperatures to do well with an intake fan sitting right behind the video card, but as a whole the C70 just isn't competitive.

CPU Fan Speed, Overclocked

GPU Fan Speed, Overclocked

There does seem to be one place where the C70 holds an advantage over the 550D, though: fan speed on the CPU. The 550D has virtually no thermal headroom left on the CPU, while the C70 can probably handle just a little bit more. On the GPU side the situation is flipped, though that could also be chalked up to slightly higher ambient temperatures during testing of the C70.

Noise Levels, Overclocked

Under load the C70 winds up being the loudest case we've tested, with even Fractal Design's $40 Core 1000 besting it and generally providing a better performance profile overall. Meanwhile the 550D is able to provide comparable (or better) performance at substantially less noise.

    Me too; appearance wise, I think it looks pretty cool. Otherwise, not so much, but it gets a "+1) from me for appearance.

    What I really want though is a case that will handle a 10-slot mainboard. Your case can't, it's not in the running for my dollar.

    ;)

    I think its awesome. I painted a case ammo can green for lanparties 15 years ago, I loved that hunk of case and 17" CRT :)

    All they need to do is team up with LG or Lite-on to make a matching faceplate.

    I'd love to know how easy it is to set watercooling up in this case. If that's what they were aiming for it might explain the bad thermals for an air cooled set up.
    Not that they shouldn't be trying to do both well.

    I really feel like Corsair's cases, similar to most of Antec's higher-end cases, are designed with the idea and suggestion that the end user will install more fans. Most of Corsair's cases are also designed with a fairly obvious radiator mount, too.

    Would be interesting to see you go back to a few cases (for example, the 500R, this case, and the Antec 1100), add 2 fans per case and a 240mm rad, and see how they do. I can't imagine anyone would spend $100+ on a case just to use the stock fans.

    "I can't imagine anyone would spend $100+ on a case just to use the stock fans."

    I can't imagine paying $100+ on a case and NOT using stock fans. That is a good bit of money to be spending for bleh cooling. One should not be asked to pay that amount, then turn around and spend more. Either sell it for less and I'll buy my own fans, or perform reasonably in a stock configuration. Just my 2 cents.

    Pretty much every case I've ever used, I've added fans to the stock configuration. Mostly extra intakes.

    What kind of 1d10t spends a crapton of money on a rig and DOESN'T buy some bada$$ fans to go with it? Thats like buying a McClaren F1 and NOT buying z-grade tires to hug the road... or buying a Cadillac Escalade without the spinners then b1tching that you're caddy doesn't have enough chrome on it. Or buying an 84" tv without the sports package. Think about it...

    I know this is an old comment, but I had to reply: A McClaren F1 *does* come with extremely high performance tires from the factory. Absolutely no need to upgrade those until they wear out. :)

    This case comes in three colours from the get go, yet I still can't get a White 550D?

    Rather.....annoying!

    This actually seems to be a decent case, and since aesthetics were obviously in mind here, I can't stand the fact that they cut side-vent fan mounts/perforations- I personally have stopped running my systems wide side fans as I don't run a dual-GPU setup and with logical fan placement and case design, side fans are unnecessary (and can often times hurt airflow if you're not smart).

    Just my personal preference- for cases with large windows (see: aesthetics), fan perforations are ugly and can let out noise and let in dust if you're not using them (and if you are, you need dust filters, obviously).
