Cooler Master Cosmos C700P Review: Thermals, Noise, & Build

2017-10-04
the Coolermaster see 700p fits the cosmos lineage but has some new designs that attempt to modernize a case once fit for the Super Tower market integrated RGB LEDs and the top and bottom panels are part of this as this is the decision to opt for tempered glass but new features also make an appearance modularity for instance creates an inverted or rotated layout for stack effect cooling or just for inversion and our present solutions and modernizing that design this is also painstakingly slow to execute but it gives you something different the shrouds are also fully present now as you plank all ugly aspects of the case and an abundance of filters also fit the modern case design requirements before getting to that this video is brought to you by synergy the software that lets you share a keyboard and mouse between multiple systems if you have limited desk space and multiple computers to command synergy removes the need for separate peripherals or a KVM and works as over the network software use our link below to get 50% off the home or provision with SSL so we kind of already reviewed this case when we did our PAX West build but now we have more home base opinions on it we have some thermal numbers noise numbers things like that and before we get any further I want to point out if the lighting is a little bit different from normally if it seems like this side has less light hitting me then you're used to its because this case is so massive that we can't really reasonably get the lights to shine over it from that corner this thing is huge so it's one of the biggest cases we've worked with lately perhaps rivaling the Vue 71 the be quiet dark based pro 900 white Edition if we put all three of those cases right here you wouldn't be able to see me so it's big in fact it's so big that Coolermaster wasn't sure how big it was when the case first launched their website listed the weight as about 57 pounds or 26.2 kilograms presently they've updated the site it's now 48 to 50 pounds somewhere in there so regardless of which size you take it's heavy and maneuvering the stain while building is one of the big challenges but fortunately you only have to build in a case once normally so not the biggest problem and people who want this kind of case know what they're getting into but just be aware that once it's built and it weighs 70 or 80 pounds you're probably going to want to move the thing into other rooms for testing yourself rather than have employees do it because you don't want injury claims so keep that in mind if you're in the business of reviews but this thing I mean just this is generally how you move it once it has a system inside of it you're going to lean it back and pivot it and this is where some of the design elements that coolermaster is invested in here actually pay off so I've seen two sides of what people think of these rails some think they look stupid and look like sled components or skis and something they're awesome regardless of what you think from a aesthetic standpoint from a practicality and function standpoint they're actually really good they're bolted into the chassis so you're not going to break off you can lift the thing and carry it like this if you wanted to and they also serve as a means to lift it where you're not gonna rip components off like that because if you did that you lift it from the back it's gonna suck if this thing comes off and you don't realize it's gonna come off and you drop the whole computer so as you'll see soon this is part of Coolermaster is kind of present design tropes where they've got these thinner cheaper plastic panels that attach in places like the front or the back or the top in some instances that come off very easily again aha but provides some kind of visual I don't know a coup trend and so some kind of visual extra that helps round out the case in this instance but also you don't pick it up there because you will lose a foot when you drop it all that regard aside though the case actually obviously is pretty easy to build in for the most part it's a large case so it's kind of hard to screw that up easy to put things where they belong gets a little more difficult when you want to invert it or rotate it for stack effect cooling which is something we haven't really seen since the Raven zero two did it with Silverstone a long time ago but those rotation and inversion jobs do take some time the first time you do it plan to spend about 45 minutes figuring it out removing all the panel's putting them back end things like that once you've got it done it's not as bad but just just be aware that the extra build time required is there again though you probably only do that once so it's not the biggest thing to complain about in the world and there aren't a lot of major things to complain about on the case we actually liked it overall we tend to like these bigger cases it's got some really good features up here and thus panel for one very easy to remove and easy to clean but also underneath here is a mounting cage for radiators and fans so if you wanted to it's only two screws to access it you pull both out you pull the cage out and then you can mount your rat or your fans and reinstall it all in one piece so that's actually really nice as you'll find because the case is so big that if you're working on it on a table like this it kind of sucks to keep doing this and trying to screw stuff in so they've thought that through and you can remove pieces to build it kind of all modularly on the table and then reassemble it in fact they've done it to an extent that you can pull the motherboard tray out build on the tray reinsert the tray with the motherboard on it and keep building that doesn't apply if you have big Tower coolers but you get the idea so kind of cool in a lot of ways kind of silly in a lot of ways but that's what you get with what is effectively a super Tower let me just exaggerate how tall this is hang on okay you know what good enough you can't see the back of it because it's so tall so you don't know that it's not lined up properly yeah I don't know let's let's go through some of Patrick's build notes and then we'll go through the thermals and noise so for Patrick's notes he says although the see 700 Pete does have a large glass side panel the default layout obscure isn't much of the interior making the external LEDs the focus the power supply shroud and a large plate of metal hiding the hard drive and drive bays can be removed to make internal components fully visible but the case won't fully benefit from flashy LED fans if you were to buy them even the top panel has a double layer of mesh that would obscure such things the fans Coolermaster ships with the case are plain and functional much like the focus of this case it's going after functionality over anything else the panel includes some basic controls for case lighting which can optionally be synced with the motherboard and fan speed as well there are labeled LEDs to indicate the current settings and you can toggle them by pushing the physical buttons on the outside of the case fan speed can either be high or low which means 12 volts or 7 volts and IO consists of a single USB 3.1 type C port sandwiched between four USB 3.0 or 3.1 gen one if you prefer airports and standard 3.5 millimeter headphone and mic jacks beneath we expect to see some more high-end cases following suit and not bothering with 2.0 as time goes on but this is still among the first to do it one of these strong points of the massive fold towers we reviewed recently like the dark Bass Pro 900 the view 71 TG for example is that they dwarf the ATX board we use for testing and leave plenty of room for coolers and cable management the power supply is held above the floor of the case and has ample clearance on all sides even with the shroud installed there's plenty of room for cables there's a steel plate that screws on under the side panel to keep things secure without relying on the side panel to match everything down and generally cabling has been decently thought out in this case the size goes hand-in-hand with one of the weak points though which is that they're practically impossible to maneuver these cases the seesaw 100p wasn't quite as heavy as we initially thought as we noted earlier it's still 50 pounds though and you can't exactly casually flip it around during the build process so we left the case completely stationary and installed the motherboard and GPU without laying it on its side which is quite a feat especially with be particularly difficult to access PCIe screws the metal handles on the Kosmos cases are typically more aesthetic than functional but in this instance they were useful for hauling the case between rooms each is made of solid aluminum and held in place with four screws the front panel has her any room for ventilation at all something we were worried about as soon as we saw the case but we'll test that in moment there's a thin plastic panel covering a mesh filter underneath which is backed by an even finer mesh the top and bottom filters are constructed in the same sturdy but potentially restrictive manner and there are three 140 millimeter fans included with the case listed as 1200 rpm shipped in the lower two front slots and the rear exhaust slot for additional testing this time we chose to remove the front panel and then the front panel and filter and finally to test the case normally but with the fans shifted up one slot to direct more air over the power supply shroud rather than into it for once removing the front panel is actually a viable option for users the only indication that something has been removed is the two small slots to slot the fan into users with the optical drives may wish to remove this panel regardless of cooling performance to avoid swinging it outwards every time a disk tray opens starting with thermal specific to the C 700 P case where we reconfigured the enclosure a few different ways we see stock configuration CPU load temperature and torture tests at fifty four point one degrees Celsius over ambient with idle at four point four degrees Celsius over ambient this is what the CPU mainly cooled by the exhaust fan and tower cooler the two intake fans are installed in the bottom of the case by default and neither is on the vertical level of our CPU cooler so one pushes from the bottom front into the PSU shroud and the other pushes from the middle front into the middle of the case surprisingly moving the front fan up didn't have a significant impact on the CPU temperature we expected more air to be moved above the GPU this way but it seems like cooler master did their research and chose the stock family out well at least for our configuration the front panel restricts enough air at the top that it just really didn't impact much as much as the air is coming from the center of the front panel anyway relocating the bottom fan to the top intake position produced effectively identical thermal results of stock and removing the front panel did reduce temperature by about two degrees Celsius and then removing the filter lowered it further by three point three degrees Celsius additionally this drops down to forty eight point eight Celsius delta T over ambient and it seems like the double thick mesh filter blocks at least as much air as the solid plastic panel so if you wanted to improve cooling by a few degrees for an intensive render project it'd be easy to just remove the front panel and leave the filter in place here's a chart with the comparative numbers for the CE 700p and other cases we've seen stock temperature Delta's around 54 degrees Celsius in both the Vue 71 with an extra fan and the stock match fic Lele it's not exceptional but it's a very reasonable range cooler masters at fifty two point one degrees Celsius delta T over ambient without the front panel is it competitive with the Corsair 270 R and pushes the C's 700 P into the range of cases we consider well cooled the case ends up between the metruff I see and view 71 ultimately and always starts getting seriously outmatched once we venture into more cooling oriented configurations like VR l06 looking at cosmos only GPU thermals for a torture workload GPU delta T was fifty point four degrees Celsius with two intake fans pushing air along the bottom of the case the lowest fan is mostly encompassed by the power supply shroud in stock configuration but cooler masters shroud isn't fully sealed and the additional airflow still benefits components outside of it moving the front fan up didn't do the GPU any favors and the DT was raised by about two degrees Celsius with the decrease in air towards it removing the front panel was much more helpful though lowering delta T over ambiens by two point seven degrees celsius and a further four point four celsius with the filter removed as well comparatively fifty point four degrees celsius was already and impressively low temperature for our tests near the performance of the Rozsival : n but taking the front panel off lowered the temperature below anything on our chart except for the RL zero six again removing the filter isn't really a realistic scenario because well obviously your front of the case is exposed but it does show how much room there is for improvement there were only one layer of mash this could easily have beat in Silverstone's case coolermaster see 700 p stock fan configuration permits the case to perform exceptionally well with GPU thermals considering the closed off low noise front panel the case marginally outperforms its fellow behemoths that be quiet dark bass pro 900 and then we'll take 4u 71 moving onto 3dmark testing for some realistic scenarios the stock see 700 P kept the GPU Delta down to 55 degrees Celsius during a fire strike extreme stress test just a bit higher than thermal take score P 3 removing the front panel would undoubtedly lower this further but the stock GPU cooling performance already looks pretty good compared to other cases on our charts rendering a blender test file on the CPU CPU DT reached thirty eight point three degrees Celsius on par with the functional but forgettable silverstone KL zero seven GPU cooling performance is also good to middling with a dt of twenty seven point two degrees celsius when rendering on the GPU this backs up the torture test conclusions that the c-- 700 p has good but not incredible stock cooling and that this extends to real-world scenarios with the fans at full speed and in stock configuration the c 700 p is on the noisy end of the scale at thirty eight point two DBA with the s3 forty elite and metruff IC nearby this case does have an external fan control though so there's a convenient way to instantly drop that noise level when the system is idling the front panel of the C 700 P contains a sheet of acoustic foam which apparently does a pretty good job since removing it but leaving the mesh filter in place raises the noise level audibly to forty two point one DBA the optimal balance of cooling and noise depends on user preference but leaving the front panel off and the fan set to low until necessary would be a good compromise overall it's a decent case it's just three hundred dollars is a lot of money and at three hundred dollars you really need to be perfect for the user looking for a case to be worth purchasing we can't make that decision fully for you we can present as much of it as possible but ultimately you have to look at the thin and that's up to you so in this range we recommend looking at the be quiet dark bass pro 900 it's a little bit cheaper and is pretty much the same size it might be worth looking at the view 71 and it's a lot cheaper than this but it's a slightly different market as well there are plenty of options from companies like Lian Li and in win in this price category that tends to be where they reside for the most part so really just pull up their entire catalog cuz half of its going to be in this price range but what it comes down to is why why do you want it do you want it for a sort of home-based server solution because if that's the case it's workable it's just there are a lot of features you might not want and that's true for a lot of these cases that are this size in this price inverting the case is something you do want if you really want an inverted case it might be worth looking back in time at the Silverstone Ravan zero two or maybe the Corsair 600 C which is much cheaper but it's inverted and that's the only layout you get so it's going to be cheaper because it doesn't require the tooling this has to offer three different orientations for the board and we did build with it inverted at the PAX West build event we did it's fine it's just it takes some time to do it so so expect that as well the $300 cost just to kind of put this out there isn't and on fair price it's just a high price you look at the tooling that goes into this thing tooling on cases like this can cost easily upwards of six hundred thousand dollars depending on which company you're talking to and I don't know what the tooling to this costs but I know what tooling cost for a lot of other cases on the market and it's not unreasonable to be in the 1/2 million to million dollar range depending on what the case is to pay on how much they can pull from the previous version of the case and reuse things like that so it makes sense it's an expensive case they've got tempered glass on here that's curved which has questionable yield we're not sure how many of these they're able to actually ultimately put on the case but it's not 10 out of 10 I can tell you that much so that's why the price is high but yeah I mean it's it's really not a bad case it's just expensive so that's kind of up to you at this point there are plenty of alternatives at lower prices though if this is too much for you so that's all for this one as always you can go to patreon.com/scishow help us out directly you can go to store it I Kara's access net to pick up a shirt like this one subscribe for more hopefully the lighting and the audio will be better the next one if you don't like them this one because we won't have than here to soak up half of my audio and one-third of my lights I'll see you all next time
