What are you gonna do with those Ghost Recon codes?

I admit experiencing a tinge of regret when I was forced to remove the DRAM heat sinks, but not enough to venture into the Kingdom of Liquid Cooling.

Regarding the Ghost Recon downloads, well, I'm using one of the downloads, but I also have one lucky nephew who will be getting not one, not two, but three download codes for Ghost Recon, Mass Effect and his choice of Dirt Showdown, Deus Ex or Nexuiz...

Agreed-- they should probably stick to creating cases. The fan controller is a bit nutty, however, so they should refocus on perfecting *everything* in the case, including the fan controller...

Derezzer - Noctua Heatpipe Fitting

The Cosmos II is so spacious, even Noctua's big NH-D14 looks normal-sized. Everything put into this case recedes deeply and appears smaller. The clearances are considerable between the heatpipe towers and the top and rear case fans, so I decided to add a third BeQuiet! 120mm Shadow Wings PWM fan on the rear tower. Noctua (located in Austria) quickly processed my request for extra fan mounting hardware, and shipped it Priority Mail. I am very impressed! Unfortunately, clearances between the towers and the Corsair Dominator DRAM modules was poor, and I was forced to remove the DRAM heat sinks. The BeQuiet! fans replace the stock Noctua hardware; essentially, at full-RPM, the Noctua fans are slightly better performers but also slightly louder. I decided to give up a little CFM to gain a little reduction in decibel level. If performance turns out to be an issue, I can always bring back one or both Noctua fans.

Derezzer - Power and Storage


The Enermax power supply is amazingly small given its modular design and power rating. The clip attached above the power chord adapter is a nice touch, safeguarding inadvertent pulling of the plug. The lower storage bays are very functional and easy to work with. It required less than 15 minutes to install two 4TB RAID-0 data arrays and a 1TB RAID-0 SSD boot/scratch array. The roomy lower chamber isolates the power and storage components; this hardware should remain cool with three dedicated 120mm intake fans, along with adequate passive exhaust on the other side of the case.

I consider this lower secondary storage area the heart of the system, because I/O throughput has the single biggest impact on my productivity. Having insufficient and/or slow memory and secondary storage/scratch space dramatically impedes my editing work.

Derezzer - In CrossFireX

Two 7970s is overkill, especially since I don't game much, but when I do I prefer maximum resolution at 2560 x 1600 whenever possible. This pair from XFX should do the job right.

I selected XFX because I was looking for slightly lower noise and cooling numbers compared to stock hardware. I didn't want to risk installing after-market cooling myself, so I decided to go with XFX and its Double Dissipation and Ghost air cooling approach. When under heavy gaming load, these cards will be the source of significant heat. To help keep them relatively cool, the huge Cosmos II and expansive MSI mainboard are key factors, allowing plenty of space for air flow around/between the CrossFireX configuration. Two open rear exhaust slots remain on each side of both video cards. Also, two 120mm fans mounted on the side case door will intake cool air directly into the GPU space.

This solution is probably the most that can be done without resorting to liquid. Essentially, the entire build is an experiment to determine what kind of performance can be attained with a purely air-cooled configuration...

Anyone who puts together an opening video to announce their build log....is going to do a good build log.

Derezzed Fan Controller

The Cooler Master Cosmos II Achilles heel is the fan controller, which causes many fan models to tick, sometimes with loud clicking noises whenever fan speeds are changed. I'm beginning to think the folks who have simply switched to a third-party controller took the right path. However, I decided to take Cooler Master's free replacement offer, and after a three-week wait an entirely new head/controller assembly arrived last Friday.

As a back-up measure, I also decided to go with Enermax manual-control case fans, which override and regulate fan speed locally with a small adjustment switch-box. If the Enermax fans misbehave with this Cooler Master controller, the plan is to keep the Cosmos II controller set on high for maximum power, and then manually regulate each fan down based on fan role/location/performance requirements.

It is a shame the case's fan controller is so problematic, given its otherwise excellent design. I probably should have just went with an entirely different fan controller...

Derezzer - Dremel Air Wolf Mod

Dremel is your friend. To maximize front intake flow an "Air Wolf" procedure was undertaken; about ten minutes was needed with the Dremel to drill out four rivets securing the remaining middle rack mount. Depending on eventual performance testing results (case, CPU and GPU temperatures), the stock 200mm Cooler Master fan may need to be replaced, but I'm giving it a chance to remain the only stock fan in the build.

This is the final modification, although there weren't many significant changes planned in the first place, since this is a relatively conservative/traditional build. Despite the fan controller, I am very pleased with the Cosmos II case. Clearances inside are fantastic. There is plenty of space between the case and main components. I am hopeful this configuration will provide good heat dissipation and thermal numbers while keeping the decibel level down as well. We shall see...
