Obsidian 650 or another alternative?

post #1 of 10
Thread Starter 
I'm thinking about pulling the trigger on a Corsair Obsidian 650D in the next couple days. I really like how smooth its appearance is and the rubber grommets inside look like they'll make cable management a breeze.

I have a couple questions/requests, however.

1. I've heard it's not the best case for air cooling. The only watercooling I might be doing would be a standalone CPU loop (though I've also read that large air coolers like the Noctua can outperform some of the pre-assembled CPU water loops, so I'm not set on a CPU loop). Is the airflow in this case going to be solid or should I put it out of my mind despite how much I like the looks?

2. I'd love to see some suggestions of similar cases that could save me a little money from the relatively pricey 650D. I like the clean, professional look (no LEDs, easy cable management). More metal and less plastic is a plus, as well. And of course, good airflow is highly desired.

Thanks in advance for your time.

I have heard the same with regards to air cooling this case.

I haven't had a problem with it. I use a CoolerMaster Hyper 212 Plus with a push/pull configuration, and as I type this I am running 29, 30, 30, 29 according to Core Temp. I have 5 programs running, nothing too CPU intensive. Running Prime95 I will hit 52-56 max between my cores. My HSF blows bottom to top.

I do have a total of 6 fans in my case. The 2 stock 200mm: front in, top out, 3 CoolerMaster R4's: 2 on HSF and 1 mounted to the top of the second HDD cage which is mounted in the back position, and 1 Scythe Gentle Typhoon 3000rpm in the rear as an intake. I guess I technically have a seventh fan if you count my PSU which intakes from the bottom.

As far as everything else goes, I love this case. It looks great and was easy to work with.

Just my 2c worth...hope it helps,

Rich

Well I have the 650D currently, but I have a 800D waiting for me to switch over into (hopefully tomorrow, or saturday). I found the 650 to be a little too small for me personally. However I am going to be running 2 rads and 2-3 blocks so thats the only real reason behind me switching.

For the little bit that I've had it, I've loved it. The airflow isn't that bad, its the first time I've heard someone say the 650D has bad airflow. I think you maybe confusing it with the 800D which is definitely designed more towards water cooling.

With the huge 200MM fan on the front of the 650D along with the 200MM on top and the 120 on the rear, its gets more then enough air. And it truly is a beautiful case.

For the price you could get a lot of other cases, big ones at that, but they definitely won't compare in the looks department, thats only my opinion though.

The cooler master haf series, 922, 932 both a lot cheaper, and probably perform just as well, but in my opinion are really ugly compared to the 650/800.

I think over all you would be pretty happy with it. Air flow really shouldn't be an issue. It's an amazingly user friendly case that you will love.

No problem keeping my PC cool, and thats with the 580 Lightning spitting hot air inside the case. The front fan grill causes some noise though, you can read about it on Corsairs Forum.

Your 6950 might not make much heat, but with my 470, when I switched front-to-back instead of bottom-to-top airflow, I dropped about 5 or 6 degrees load temps. (just by pulling cooler air from the front instead of hot air directly off my GPU.)

I did originally try that, then I decided to increase my positive air-flow. I wanted my rear fan to be an intake and didn't want to have 2 fans blowing into each other. I couldn't see blowing it back to front so I ran it bottom to top. I am running maybe 2 degrees cooler this way...maybe. I don't recall the exact numbers, but I knew I used to idle just over 30C and now I idle around 28-30.

I will say that at the same time I also added a 120mm fan which sits between where the top HDD rack normally is and the GPU. It helps the air from the front go directly over the GPU.

Cool. That works. I have an Antec 902, and the 2 front 120mm fans are moveable. I have one up at the top of the case, with no HDD's behind it blowing directly into the intake of my 212+, then the 2nd fan blowing it into the exhaust...plus the huge exhaust fan up top.

SORRY for the thread hijack

(for what its worth, I do not recommend the 902)

Thanks for all the input everyone. Now that I'm sure it can perform, I think it's definitely the case I'm looking for. As a few of you have said, I don't think there's a better looking case on the market and I feel like this one could last me awhile. I appreciate all the quick feedback.
