Nope, but then again I have water-cooling[^] Cool
so do I. Sadly the gap between top end air cooling and water cooling with a 2x120 rad has been shrinking rapidly. My next upgrade is probably going to be a 3x120 rad and a bigger case; currently I'm thinking a mountain mods u2-ufo[^].
3x12=36 2x12=24 1x12=12 0x12=18
That case is a monster :) I also feel a 2x120 rad is just a little too small for an i7. At least I can make space to add another 2x120. Anything larger, and I would need to buy something bigger too. I really like that Silverstone TJ07 though, but it is not available locally, and shipping would be a killer from anywhere else.

I too have been running SETI@Home for years, so 100% all the time here too. I did have my fan turned down too low for a while and I was getting some unexpected freezes every now and again, but after turning up the fan speed it has been fine ever since.

My current case[^] is a monster as well. Unfortunately its becoming a victim of the ever growing GPU length. It's only 12" front to back; after subtracting the thickness of the front panel and the fans it only just has room for a 10.5" card. ATI's 5890 card won't fit, and the more common 10.5" cards are very difficult to install. Actaully it's one of the smaller mountain mod cube cases. The extended version is bigger front to back, while the Asecendency is taller. OTOH MM sells a 12" tall expansion box to install underneath their cases if you find yourself needing more space. :omg: If I ever decide to watercool my GPUs that would give me the space to do so without needing a new case for the extra rads. OTOH the pedestal box costs as much as a normal premium case. :doh: My only disappointment is that they don't have any back panel options that would let me have a horizontal mobo (better heat dissipation with 2 aircooled cards) with exhaust fans placed above the GPUs.

I thought I did as well; but because my rad extends slightly beyond the edge of the fans I'd need to make new screw holes at a minimum to install it. The only rad that will fit double in the case is thermaltake's; and their watercooling products have a poor reputation both for leak resistance and performance.

Has anyone had any problems with running a job for more than an hour that pushes most of the CPU cores to 100% usage? I'm planning on making some animation, and with each frame taking about 5-7 minutes each, a single second of animation is going to come in around 2 hours 20 minutes or worse. For a 10 to 20 second clip that could easily cause the CPU to run at 100% for almost 12 hours or more. I've never had anything run that long on any system I've owned and I'm not sure if it's going to overheat the box, or if it's hard on the CPU to run that long. Anyone have any experience with this on a desktop system (for the record it's an 8 core MacPro)?

Sounds like a perfect fit for the Amazon EC2. If you have a couple of dollars to spend you could render all of your frames across a large farm pretty cheap. http://aws.amazon.com/ec2/#pricing[^]
Actually Houdini has a service for this (on Amazon EC2) which I'm hoping to use. However if I can't get that to work (which I can't at the moment), then I'll have to render the frames at home.

((λ (x) `(,x ',x)) '(λ (x) `(,x ',x))) The Scheme Programming Language – Fourth EditionYeah, interesting if some of the ideas were a bit silly. I'd be shocked if 5% of the buyers bought any of the accesories intended for the 2nd PC. I ended up using the miniItx are to mount my pump and res. It's got a few spots where the otherwise excellent cable management (route everything behind the mobo and just pop it up at the appropriate edge hole) flopped as well. The front panel USB, etc are attached to the removable front panel, not the chassis. IF you slop the cables loosely through the HDD cage this isn't an issue; if you take advantage of the fact that there is *barely* enough space between the drive cages to route the cables it becomes a major PITA. An extra 1/4" of width would have done wonders there. That was rather frustrating considering how polished everything else was; right down to the tapped holes in the floor of the case and back of the mobo case to facilitate screwing down misc parts. :sigh:

Pretty much sums up what you should expect from hardware. Never more than 80% of what you hope for. :) Like my silly case's top fan mounting holes. Nice, but dont work on a radiator, had to drill more holes. Also, the top space is just to small. Even an extra 10mm would have made a world of difference... I had to mutilate that one fan 'touching' the CPU power connector. Lucky, I had 1mm clearance on the RAM levers.

How many servers does it split the load over concurrently? Since amazon's using commodity servers you'd probably need at least a dozen to match your systems raw throughput. For that matter how expensive will rendering that way turn out to be; when you're potentially buying over a server-day per render the costs could add up fast.

They might have been sized for some other vendors rad. Mountain mods offers 2 different spacings 15 or 25mm for its fan cutouts to support different vendors rads.

Mine was off by about 4mm :(

I don't recall. I'm trying to set up a small test to see how well it works. Even if I could offload small parts of the whole, it would be really helpful. If I get it to work I'll definitely post something here about it.
