Pros: *Spacious. Fits oversized GPU's and has plenty of room for SSD's/HDD's.
*Ventilation and radiator mounting options are great. (120x(up to)360mm top, 240x240mm side, rear 140x140mm)
*Built in holes for running hose to an external radiator.
*Lots of options and space for cable management.
*Collects surprisingly little dust for having no filters.
Cons: * Half of my fans started making noise(ticking, etc) in the first 1.5 years, so I've since replaced all but the front intake.
* Mine weighs better than 80lbs and I don't even have waterblocks on my GPU's. Don't think I'll be taking it to the lan any time soon.
* My case came damaged from the MFR. One of the feet was shoved over an inch into the bottom of the chassis with no damage to package. I chose to re-align it myself rather than deal with shipping.
Other Thoughts: If you're using this for air cooling, you may consider purchasing some filters, which will of course decrease your airflow, but it depends on how dusty the environment is and how often you want to clean it.
It's spacious, although with all of the stuff I have in it, the motherboard mounting(full ATX) should've been moved up an inch. I have a 360mm rad on the top of the case which means I have to mount the PSU on the bottom and I can't get more than two GPU's into my MOBO due to verticle limitations. I also only have access to one PCIe port. If you have some really thin GPU's, a slim PSU, or a motherboard with different slot orientation this may not be an issue. If you want more than dual SLI though I'd recommend the HAF935 with a HAF915 stacker to stick your PSU in.

120x360mm radiator with 6x 120mm fans
Various fan mods; all I hear is "woosh". xD
Pros: I've had this for about a year with no issue. This is the nicest power supply I've owned to date. Even comes with a bag for all of the modular cables. Provides more power than probably anyone needs in an Nvidia/Intel gaming rig short of 4-way SLI. See other thoughts; I list power demands of my components under benchmark and real world conditions.
Cons: Nothing to do with the power supply, but if you get a CM product with mail-in rebate, don't hold your breath. When I built my rig I had 3 components with CM rebates. I only ever got 2 of the 3 and it took them 6 months to fulfill.
Other Thoughts: Measured PSU power draw increase from idle during benchmarks:
i7-4770k @ 4.4GHz - Prime95 small FFT's stress test: 133W
Gigabyte GTX680 4GB OC(two-way SLI@1202MHz core & 6508MHz MEM)GPU draw during unigine heaven, max settings @ 1080P: 295W avg, 325W max.
Corsair Vengeance 2133 RAM draw during benchmark: 10-29W
Fan controller +12W (8 fans(6x120mm, 1x140mm, 1x230mm@100%)
RGB LED controller 2W
Power draw from computer at idle: 78W(includes all previous components, two XSPC D5 water pumps @ 1900RPM, 3 Samsung 840 Pro's striped, Creative SoundBlaster Z sound card, & one BDRW drive).
Max theoretical power draw on PSU: 538W (579W drawn @ 93% efficiency)
Gaming operation with everything set to max playing Crysis 3 @1440P: 437W (470W drawn @ 93% efficiency)
Note: these power levels are based off of the power that the PSU is using, the output should be 80-93% efficiency according to unit specifications, so power output may in fact be less than noted. Calculations made assuming that PSU will not be more than 93% efficient.
All that being said, you generally want to shoot for a PSU capable of at least +30% over what you expect being able to throw at it. This will make a good PSU last longer and improve system stability.
Pros: I have 6 of these on a RX360 radiator and they're quiet! Even at max RPM(1600 according to my mobo, PWM controlled) they were barely louder than my water pump rated at <25dBA.
They work OK on voltage control. I didn't notice any increased noise.
Overall, it's a nice PWM fan. Very good for low resistance applications. Acceptable performance in push/pull on radiators.
Note: the rest of this review is largely radiator and negative resistance specific.
Cons: Cost. I got mine for $9/ea off newegg on sale, but more than that and these start to become pretty expensive considering I'm running 6 of them. It all depends on how much of an issue noise is to you. There may be other fans out there that perform better with less noise, but I did A LOT of looking and didn't see anything better other than the Gentle Typhoons which are discontinued.
General negative, not limited to these fans: specs can be deceptive. I would recommend not buying any fan solely based off of the MFR listed specs as most are generally tested in an open space without negative pressure or resistance to airflow as you will experience in most real world applications. That's where the static pressure rating of the fan would come in if it were accurate, but from what I've seen from other people's test results these are not the most powerful fan out there.
I wouldn't use these for a radiator unless you're really looking for something quiet and then I would also only run them in push/pull with gasket material as these are not a perfectly square shape. Running gasket on a radiator will also help space the fan away from the rad which is a good thing because it will allow air to flow through the fins more evenly and theoretically reduce how much the fan motor needs to work to get the air to flow.
Other Thoughts: I own various cooler master fans(the cougars are better than all of them) and a 140mm noctua which is really nice if not a bit loud. In my experience the best fan that I've come across in terms of noise/static pressure/cost ratio is the 1650RPM fan made by XSPC. I got them with my 360mm radiator and they are available separately. The reason I'm not running these on my radiator is because XSPC doesn't make PWM fans and my Gigabyte Z87X motherboard doesn't support voltage regulation as a fan control option. They're louder than the cougars but the performance is that much more as well.
Tip: there are forums and websites out there where people have taken it upon themselves to do comparative spec reviews of multiple fans measuring dBA and cooling performance. Check out Martins.
