Introducing the Corsair Vengeance C70

Corsair has had an excellent run as a case designer, showing growth with each new enclosure by adding some features, subtracting other ones, moving things around, and generally continuing to experiment. The Obsidian and Carbide lines in particular have shown healthy progress, but today Corsair launches a fourth line under their popular Vengeance gaming brand: the Vengeance C70.

While the exteriors of the Obsidian and to a lesser extent Carbide cases have all been fairly austere, the Vengeance C70's target is pretty clear: they're going after gamers. Thus far, products in the Vengeance market have generally been of high quality and haven't been particularly ostentatious, but the C70's external design is an unusual step for Corsair. Is the C70 as a whole part of Corsair's continued evolution as a case designer, or is this their first major misstep along the way?

For the first time since I've started reviewing Corsair's cases, I'll admit I experienced trepidation when I saw the press materials for the C70. Military green? Handles on the top? Industrial-style power and reset buttons? This wasn't the Corsair I knew, the company whose most ostentatious design so far was the Carbide 500R (or, arguably, the well-received Graphite 600T). Sure, the C70 is available in white and gunmetal gray (a personal favorite) as well, and the interior is vintage Corsair, but it still feels to me like an odd bird in their lineup. Before we get to the detailed analysis, we'll start with the regular specs table:

On paper and without seeing the case, there's not a whole lot that stands out with the C70. The one area that looks unusual is the sheer number of fan mounts available. While testing the Vengeance C70, the enclosure that remained fresh in my mind was the Corsair Obsidian 550D, their case engineered for silence. In terms of expansion and cooling potential, the 550D isn't actually all that different from the C70; with the C70 you lose a 5.25" external bay but gain three fan mounts, which would be more impressive if the flexible 550D wasn't already capable of supporting eight. That owes to Corsair's positioning the C70 as a potential go-to for watercooling, with two different places to mount 240mm radiators. Indeed, all of their review materials present the C70 with Corsair's own H100 closed loop liquid cooler installed. We didn't have a watercooling kit for review, unfortunately, so we're looking at the C70 primarily as a typical desktop chassis.

    So those nitwits of you complaining about the arrangement of the front fans, did you actually look at the review and perhaps see where he removed the front case cover and there were *gasp* holes to screw in a fan, and space inside the cover to accomodate such fans? Yes I know it blows your minds but sometimes you can actually put fans in places where there isn't a fan that comes with the case. Every case I've ever owned has had at least 1 slot that didn't come with a fan in it. if there is a spot for a fan, and it doesn't come with one for there, i put one there, and guess what, i always have great airflow. I also tend to replace the cheapie fans that come stock, with much more powerful fans. So reviews like this don't mean much to me because i will always get better numbers when i use the same case. I look at how the case is actually designed and this thing looks amazing as far as number of fans supported and positioning.

    Hi, I got the C70 just 2 weeks ago, the design (outlook) is so cool, would like to have advise how to install my fans, details as follows:

    VGA card--------MSI 6850 OC
    CPU Cooler ---cossair H60
    Fans-------------2 pcs SERVO Gentle Typhoon ( for H60)
    2 pcs GELID Silent 12
    4 pcs cossair stock fans
  • panopset - Sunday, October 5, 2014 - link

    Looks like the H60 has a similar radiator size as the Zalman LQ315. The built in top fan was compatible with my radiator, so I have the radiator sandwiched between the Zalman and Corsair fans. I had to move the whole thing to the top front fan mount because otherwise it would bump in to my memory cards. That maxed out the radiator tube length, but it still fit.

    your missing the x2 120mm fans for the "Front", look behind the front chassis access panel

    I really love the styling of this case, and as someone suggested the best way to ensure the smoothest air flow would be to take out both bottom cages and put the twin fans on the front and to have a solid perspex side made to replace the fan mounted one. Personally for me this will be my second build of a computer and this is defo the case I will be going for, love the unique design (I find most of the cases, black and boring. At least this one wants to be noticed.)
    For my new build I am going with -

    5 x Noctura F12 fans
    Only the H100 (not the i) water cooling
    Gigabyte FXA990 UD3 Mobo
    8320 Cpu
    R9 270 Gpu
    8 Gb of Ram
    Be Quiet 630 Psu
    Keeping my SSD (OCZ Vertex and 1Tb backup HDD)

    And at the moment I am so excited, might not be the world's most amazing computer but for me it will be awesome.

    You state that, "...the thermal and acoustic results recorded..." and "Ambient temperature is also measured...".

    The differences between your recorded temperature results and those done by Corsair are almost certainly because of the temperature instruments (and probes) used to perform the recorded results. What is your temperature instrument used to record these readings? Is it calibrated by an accredited laboratory? Or, are you even using an external instrument to record the temperatures or are you relying upon different motherboard readings? It doesn't take much to alter temperature readings especially when you are only looking at 1 or 2 degrees C differences.

    Your test setup should include how you determined the actual temperature readings.

    The temperature references in this article mean nothing until the temperature method can be explained.

    Additionally, is your "acoustic" instrument calibrated? I'll go out on a limb here and say it isn't!

    Prove me wrong!

    I know this is an old review, but I wanted to ask: Has anyone tested this C70 case with both drive cages removed and the two drive cage fans moved to the front of the case instead? Seems like that would increase positive airflow from outside, which should improve cooling considerably. In this day and age, I just don't understand why gaming cases still have all these drive cages, especially at the expense of cooling. I have a pair of SSDs, and honestly the second one is only in there because I have no other use for it. I could easily run with just one if needed.

    Anyway, this normally isn't the kind of case I'd go for (I'm a quiet case sort of person), but I do like the tough design and especially the handles, since I often have to carry my computer from my office downstairs to my home theater upstairs.

    Bought this case for its ammo can look, easy to build features. Was noticing poor reviews of thermal tests. Much of the poor thermal results is loss of pressure from all the extra vents where there are no fans. The intake fans behind the disk drives moves in cool air and mimics high end rack servers where the fans are actually in the middle of chassis. The exhaust fan helps remove heated air from the cabinet. I'm using an air cooled CPU fan cooler to avoid fan noise directed right at me. What I'm planning to do is seal all unused fan openings top, side and anywhere else I can find leaks. Then the supplied fans will actually do the work they were meant to do.

    I agree about the amount of un-needed ventilation. I've seen people take the clear acrylic side and replace with a solid (non fan mount) window. Also, if you're not running water cooling, i would maybe seal up one (half) the top and bottom vents, or just the bottom while using two fans venting on top (might be over kill). Also, people remove the hdd bays and move the fans to the proper placement up front. I'm sure that would, with the proper fans (non water cooled), bring temps down significantly.

    Commenting in 2019. After I purchased a used C70 and have used it for several months.
    First I will disagree with your opinion on esthetics. I agree, it isn't a crowd-pleaser, it is much more specific to a narrower target market. I enjoy military themed stuff and find the case a bad-ass sort of way. Also, I swapped the side panel for one without the ventilation holes for fans since that side panel should just be a single clean pane of acrylic. Which it is now. And looks fantastic.
    Second, the cooling from the factory is rather sub par. Absolutely agree there. But, you can add lots of fans which means they can be slower and quieter fans because they are large enough and numerous enough to move air effectively through the case. (again, the side panel fan positions are gone leaving a clear airflow from bottom-front to top-rear. I use two 120mm fans in the front behind the front fascia, with two more behind the disc mount rack to help pull more airflow through that confined space I also have a 140mm fan on the floor pulling air up into the case. Then in the back I have a 120mm blowing out and in the top I have two 140mm fans blowing straight up. Assuming I get 50% of rated flow, I can get up to 200CFM flow with all fans on high. However, I tend to run them all at 30% which is probably less than 75cfm and rather quiet.
    To prove that the case cools well, I mounted an FX-8350 and an R9-390 in mine before I added any case fans and just leaving the side panel off was enough. However, once I added the fans I can reliably cool the whole PC even when working it particularly hard.

    Now, this isn't a QUIET type of case. There just isn't enough airflow efficiency to get air through the case easily enough to be super quiet. But, if you don't mind slight fan noise (I don't mind the fan noise at all...I love air cooling so I have a weird enjoyment of the sound) then this case can work just fine.
    Granted, now that they haven't been in production for 5 or 6 years, this whole "user-review" is moot. But, for anyone who is looking at getting one of these classic cases, don't worry about the cooling so long as you don't mind lots of fans.
