Corsair Obsidian 700D Installation Details

Have a look at the internal drives chamber. Please notice all S-ATA cables are connected from behind, and so, there are no visible cables at the front of the case as many other brands. I find this very elegant, and it doesn't represent a problem since the side panels can be removed so easily without screwdrivers.

Moving to the cable-management theme, here is how it looks. Every cable can be routed behind the motherboard's tray to reach its destiny by passing across those rubber grommets near the needed connector.

Corsair_700D_Cable_Management1.jpg

Not everything is perfect, and this is no exception. Corsair added a pair of rubber grommets to pass PSU cables through them. Unluckily, the first grommet is completely blocked by the PSU, and I used the second grommet to pass all the cables, including an ATX 24-pin cable. My Antec's Signature 850 watts PSU isn't as big as 1 kilowatt PSUs, so you could end removing the whole chamber's plate to gain access and more space to work. However, that would hurt aesthetics a little bit.

The superior motherboard's section looks pretty clean. I had to use the 8-pin to 8-pin PSU extension to reach the CPU 12v+ connector, but remember Corsair already ships one with your case. I didn't have problems reaching the ATX 24-pin connector, and I don't think you'll have problems as the distance isn't that big.

Talking about being nice and elegant, the CC700D doesn't include any lights or LED fans (quite obvious, because there's no side panel window). The only lights you'll notice are the power and HDD LEDs. Nothing else will be visible.

Finally, let's have a look at our main chamber and move to the temperature tests at the next section.

A very utilitarian case. I just can't believe that 15 dollars would make or break the deal. If you're going to spend 240 for a case, what's 15 bucks?

Initially, the difference was $50. Actually, when I was writing the review the difference was still $29, but at this moment, the CC700D raised its price and so the gap is smaller, almost ridiculous as you said.

Looks really good. It reminds me of the HAF X. I own the HAF X but I could easily see myself owning this too. Both cases seem to share a lot of the same qualities I like.

But I still think I'd have to go for the HAF X. HAF X has wheels, more fans and bigger fans which I think would lead to overall more CFM and a quieter operation. Also the window with side fan is super cool on the haf x

# Quieter operationa than 800D?Lutsk92 2010-11-12 06:01
Please explain to me how HAF X will have a quieter operation than 800D since it has open mesh panels letting the intern noise out and more fans.

I've been reading reviews and doing drive-bys of cases lately, studying up before I make the plunge. I'm committed to full-tower for my next case and this one, the 800D, the Haf X, and the Phantom keep bubbling up to the top of my list. Good review, thanks Servando.

Being of steel/aluminum construction, I suggest not dipping it in water so as to avoid cathodic corrosion.

Steed, the wheels on the Haf X are a good feature. My current rig sits on a wheeled caddy I custom built for it. But I see your point; the Obsidians should come with a wheel kit as it's a great option for a large case. Should come with all full towers IMHO.

The HAF-X is the only case in your list that has more than 7 slots. This might be significant if you want to run an SLI or CrossFire-X setup.

You never stop mentioning 7+ slots David :)
May I ask how many PCI/PCI-E devices do you have installed on your PC? or exactly, why do you wan't more than 7 slots? (I mentioned it on the article, but I haven't heard many people asking for it).

# Nice, but the price,....RealNeil 2010-09-20 05:38
I like this case. I like the way they have the airflow chambered and it probably works fantastically. I have a hard time with spending that much on a case though. Plenty of others go for far less and do a great job with airflow as well. My CoolerMaster Storm Scout can be had for $129.00 these days, and it's quite adequate in itself. My CoolerMaster Centurion 690 is $59.00 (cheap-a*s case) and cools quite well too. I added fans in all the places you can put them, and 8 120mm fans cool the heck out of things.
I'd rather spend the extra money for this Corsair case on something else that makes my system RUN better.
Again, this Corsair case is a nice design.

Thank you for a careful, well-considered review.

Thank you for measuring and posting the space behind the mother board tray. Having that measurement helps us.

I checked at their store, and I found non-windowed panels for 800D users, but not windowed panels for 700D.

I guess I though it was compatible with both the 800D and 700D because they have 24 by 24 inches side panal sizes.

Yo my bad I remember that they did have it for sale @ their home page before I guess they aren't offering it anymore, I just checked and they only have the one you've mentioned. (800D non windowed), another alternative is modding the dam thing. If ill see any windowed side panals for 700D in the future ill post the link here.

# Multi-GPU cooling not that good.Servando Silva 2010-09-22 21:30
As I expected, today I mounted a pair of GTX 460 GPUs and stressed them to prove this case isn't good for multi-GPU setups unless water cooling them.

Idle:
GPU1 (Top): 65
GPU2 (Bottom): 50

Load (Furmark):
GPU1 (Top):86
GPU2 (Bottom): 81

I think it's modding time...

# RE: Multi-GPU cooling not that good.RealNeil 2010-09-23 04:00
Are the GTX-460's the ones with the coolers that do, or do not exhaust their heat out the back of the case? How far apart are they positioned on the mainboard? Is there much of a gap between them?

# RE: RE: Multi-GPU cooling not that good.Servando Silva 2010-09-23 04:39
It's a pair of Zotac GTX460 1GB. They use Nvidia's reference cooler, so air is exhausted to the rear and not dumped into the case. However, they are too small, and that lower fan isn't giving air to them.
They are positioned on the first PCI-E 16X slots in the Maximus III Formula, and there's a space of 3 slots between them (where each takes 2 slots).

Maybe I'll add a side windowed panel with a pair of 120mm fan grills for GPUs air-flow.
I wanted to get a pair of MSI HAWKs, but ended with a pair of Zotac's with reference cooler...

I've been watching the GTX460 reviews to see what factory overclocked ones have the best coolers. I plan for two in SLI on an ASUS M4N98TD EVO with the AMD Hex-Core 1090T and 8GB of G.SKILL Flare DDR3-2000 RAM. I already have an Asetek CPU water cooler on the shelf and my CoolerMaster cases all have places to mount fans on the side panel.

So I'm reading everything that I can about the video cards and seeing what they come out with in the next few months because I'm not ready to buy until November at the earliest.

It should be a nice system when done.

# Best Cooler....dependsBruceBruce 2010-09-23 06:05
The best cooler for getting heat out of the GTX460 GPU is the MSI Hawk. What happens to that heat is that it gets dumped into the case, for the most part. If you've got a good airflow arrangement in the case for supplying fresh air to them and pulling the hot air away, you'll get the best results. Sounds like this case isn't able to do that, out of the box.

Hi Bruce,
I'm really waiting for your OC results with MSI HAWK. Also, has anyone seen the Colorful iGame GTX460 GPU? That heatsink is a beast!
Back to the topic, this case has great airflow for CPU and drives, but lacks of airflow for GPUs, anyway, and the same applies for the 800D. Anyway, I'm willing to do the mod.

I'm sorry, I don't know what was I thinking. This aren't reference coolers, they are actually worst than reference. Zotac kept a similar design to a GTX260 Cooler for this version. Air is exhausted at the rear, but the fan doesn't help that much.

This guy was able to purchase the side panel for the 700D and got a custom mod for $45.

##youtube.com/watch?v=GWyojqDmUTc&sns=em

As far as multi gpu setup I'm running 2 gtx 480s sc by EVGA in slots 1 and 3 with stock coolers and my gpu temps go up to 95-100 degrees . And I have (3) extra coolermaster 2000rpm fans on top as well. So you might be right but you have to compare it to other cases to conclude that statement. (My gpu normaly run that hot so i'll just leave them till Kool kepler gpu come out in 9 months.)

# No fan infrontDr_b_ 2010-09-28 21:42
Despite the bottom fan blowing up to the motherboard chamber, there is no fan blowing internally from the front onto the motherboard. Of course you could put three fans on top, but nothing beats direct airflow from the front onto the CPU/Mem/GPU area like in the Lian-Li PC-X900 and its bigger brother. The PC-X900 is not without its problems though, like no backplate to cover the hole in the motherboard which provides access to the heatsink retention bracket on the back of the mobo, tight space above and below the motherboard, poorly placed holes in the mobo for cables which are too close to the mobo and which do not have grommets like in the corsair, and the ridiculous price. But you just cant beat that direct airflow right onto the components.

# 700D Positive Air PressureTBSM 2010-11-02 13:21
The best way is to reverse the back fan(as you do for the H50) to push fresh air inside. Because the back fan is closer from the Heatsink, its a lot better. Than the warm air is blowed out by the 3 upper fan. Make sur that your cooler fans are oriented in the same way as the upper fans. Aslo its very good to have approximately the same CFM in and Out for a positive air pressure and an optimal airflow.

# RE: 700D Positive Air PressureServando Silva 2010-11-02 13:43
Well, I could actually say this case has no Positive Air-Flow at all. There's not even 1 fan blowing fresh air directly into the inside, so that's one thing lacking in the 700D. As for your recommendation about rear's fan orientation, I think it's quite useful, since the 3x120mm top fans will do the exhaust function and your CPU will be cooler. It would actually hurt somehow airflow direction, but since this case doesn't follow the (front-intake) trend, it won't hurt.

# RE: RE: 700D Positive Air PressureTBSM 2010-11-02 15:35
Indeed there is no fan blowing directly into the inside, Maybe another 120mm under the bottom 140mm will help (With the same CFM of course). I think (Its only a theory) that they designed this case for water cooling, that will explain the lack of frontal Fan. Maybe they want us to buy a H70 (Who knows loll).
Thanks for the fast reply and for your excellent reviews.

Another question, where do you think is the best place to install a H50 in this case ? I tought about the bottom conpartment ? But if you have other suggestion, they are welcome.

# RE: RE: RE: 700D Positive Air PressureServando Silva 2010-11-02 17:16
Sure, I was thinking another 140mm fan just below the lower chamber would be a great start, but additionally, one or two extra fans at the side panel would have been great.

Now, for the H50, I think there are 3 possibilities. If you're using it as exhaust, then obviously at the top. If you're using it as intake, then the one suggested above (at the rear) would be better. I don't know if Corsair's tubing is long enough to reach the lower fan without interfering GPUs installation, but you could give it a try.

# Positive Air FlowRealNeil 2010-11-02 17:57
I use and Asetek LCLC CPU Water Cooler for my i7-870 System. It's essentially the same thing as a Corsair H50, and Asetek actually makes the Corsair unit for them. I've mounted two fans on it in a push/pull configuration and it's blowing air out of the case while mounted on the rear. I also put 2 120mm fans on top, blowing air out of the case. I use 2 120mm fans to pull air into the case, one on the bottom and one in front. It all works well for me and doesn't make much noise at all.
My fans are all the same thing, Scythe GentleTyphoon, @1150 RPM and 37CFM Air Flow. Expensive, but very quiet.

A friend of mine found a solution for the lack of front airflow. He added a Lian Li PC-343 Black Fan Module compatible with any 120mm.

PS: The reverse 140mm Idea, in the back, is efficient. I use a Mugen 2 with 2 x 140mm pushing the warm air on 3 x 120mm on the top. 36 in idle with a Q6600 @ 3.6GHZ.
Note: The 140mm under the HDD is not there as decoration, without my Caviar black average 52 degree and with it 34 degree.

I've already tried reversing the 140mm rear fan and it improved CPU temps a little (1-2 degrees only). Since all the hot air is being exhausted at the top, I can't see why going back.
