A concern for me before I buy a Cosmos 2

post #1 of 15
Thread Starter 
I've been seeing a lot of fantastic reviews for this case, and I'm completely stoked to buy myself one to get ready for a big leap to SB-E from AM3. And while this problem I've seen with this case will not determine my purchase, I still want to know if it's actually a problem.

What I've heard from some people is that if you buy a Corsair 100H liquid cooler, the dual rad wont be able to fit its width plus 120mm fan's widths in the space right above the motherboard. So is this actually a real problem, and if so, can I mount my fans instead above the frame and beneath the cover on top? I'd like any input on this that may help, such as instead mounting where the hard drive bays are if the CPU block can fit through and have enough tubing to get to the motherboard.

Also, how do you guys like the case? Any other pros/cons that you would like to share?

Thanks for the help smile.gif

Pro: it's a HUGE case. biggest you can get w/o going with a custom case. it'll fit everything with little to no modding.

Con: it's a HUGE case... you may have to rearrange your furniture around the room to even fit this sucker. remember cooling isn't just about the airflow inside the case. if you put the case in a bad location where the hot air is recirculated back into the case, then you will be doing yourself a disservice by buying something that huge. a case that size isn't easy to fit and still allow for proper airflow outside/around the case. also it's easy to fall into a tendency to try to fill everything in the case and the end result is too much noise/power consumption for little to no gain in performance. the ONLY real justification for a case THAT size is if you fully intend to go triple SLi/Tri-fire. otherwise it's completely overkill and a waste of $.

for a normal machine. FT02/RV02-E would serve well if you don't want liquid cooling. if you intend to go liquid, then arc midi or 800D will do well.

Yeah, I'll be sure to not restrict airflow on this. I've already measured its specs and I'll be able to fit it into my room no problem, even after a couple inches on the sides/back for breathing room. wink.gif I do intend on going with triple cards in the future, maybe even quad, and I also like the design of this case more than any other out there.

In terms of which cooling solution I'm going for, I'm really not sure. I already have a kit water cooler but I don't count that as genuine water cooling. I may or may not want to upgrade to custom water cooling in the future, but I definitely want the option. thumb.gif

Have you considered the NZXT Switch 810? It will fit the H100 no problem.

some of the things people don't consider is the elasticity of air in a large volume container. due to the compressibility of air, the larger internal volume you have, the more fans it takes to raise the internal pressure. larger cases also have more leakage points which cause pressure loss. what does it mean for your case? more fans = more noise for the same thermal performance as smaller cases. you are better able to manage the airflow pattern inside the case on a smaller case due to the lack of options for which air can flow. in a small case, air can only flow where you direct it. larger cases can have heat pockets inside the case where air can hide.

generally speaking, the tendency to "fill the empty spots" is hard to resist and you'll end up with like 20 fans inside the case and it'll be loud w/o really improving the thermal performance relative to a smaller case:D

as for clearance AROUND the case. remember air flows in 3 dimensional space and hot air ONLY travels up if there is no fans pushing the air. most people neglect the fact that their side intake fans are drawing hot air directly from the rear exhaust of the case thereby creating a thermal short circuit of sorts. rear exhaust will create a thermal pocket directly behind and around the back of the case with slightly elevated pressure from the exhaust fans. while the side intake fans create a slight negative pressure which would result in feeding that intake air from the exhaust if you don't have enough gap in the back and the side of the case for cool air to enter and hot air to flow away.

as i mentioned, the size of the cosmos 2 is in fact it's greatest advantage and disadvantage in both thermal and acoustical performance.

No I actually haven't considered it until now, I'll look into it more, the only problem I see with it is it seems to have a lot of plastic and the top might be a little restrictive for my taste. Other than that I really like the light on the back, I like the window, and a lot of other features are pretty close to the cosmos.

+1 psyclum, How's the airflow on the 800D?

800D is good if you are looking for a liquid case. it's a poor performer for air cooling IMO. there are others who would disagree but that's my personal opinion. the 800D is a "smaller" case then the cosmos 2, but it's by no means a "small case" if you fully intend to go tri-fire, then go with cosmos2 it has more room inside to work with.

what you really want to consider is what exactly is the type of machine you want to build. "wanting" the option to go quad SLi / quad-fire is nice and all but unless you build a system around that, it's a waste of $ and otherwise performance to have something THAT huge. for example, a quadfire means a high quality 1200w PSU. unless you can actually afford 4 top of the line GPU's, it's more or less a waste of $. remember a single 7970 can match the performance of a SLi/Xfire 2 generations ago so unless you have the budget to go all out today, you are wasting $ on the "option" that you'll likely never exercise since dual or tri-fire can get the job done. you also should consider the diminishing returns factor. the cards don't get cheaper when you go from 2 cards to 4 cards, but the performance gain definitely decrease per card. how many monitors are you looking to drive on your system? what are the resolutions on those screens? can you afford that many screens? and did you figure in the budget for that many screens? remember UNLESS you absolutely need stereoscopic 3D, monitors only refresh at 60hz anyway and having a machine capable of 150FPS is no difference then a machine capable of 100FPS. the only thing you get out of that is an Epeen boner and not anything your eyes can see nor your monitors can display.

like the oracle in the matrix said, know thyself. do you REALLY have the budget to EVER use that case to its maximum potential? or are you just jumping on the bandwagon for the flavor of the month?

I will be doing one of two things for GPU's: I will either get a third 6950, or upgrade entirely to 2x 7970s or whatever Kepler has to offer. I'm unsure if I want to go with water cooling in the future, but I can say that I will be using air cooling for quite some time if I do end up switching. I currently have a single 24" 1080p monitor but am going to purchase 2 more certainly in the near future (within the year). Mind you my GPU's have 2Gb of vram so there should be no problem with 3 monitors.

So here's what I want:
i7 2011 chipset cpu/board (Motherboard: ASUS Rampage IV Extreme, still deciding on chip)
32Gb RAM
The above GPU setup
3 monitors
Good air cooling with some water cooling features.
Hopefully silent, I know it's hard to be said with air cooling smile.gif

That's straight up what I have planned for my system, if you can recommend a case that may be better suited to me that would help a lot thumb.gif

There is a clearance of 44mm between the ceiling and the edge of the motherboard. Read my post (#28) of this thread:-

http://www.overclock.net/t/1198674/cosmos-2-how-much-space-for-rad-at-top/10

 

Now, the Corsair H100 has a 27mm thick rad. If you install 25mm thick fans, it will become 52mm and the rad-fan combo should not fit.

However, as you have noted, you can mount either the fans or the rad above the ceiling and underneath the plastic roof. It is do-able (see the pic in post#322 of the thread below).

 

Read through the Club thread here for some good info about the Cosmos 2(eg delivery damage):-
