My goal with this rig was to build a PC that could play the Witcher 3 at or near ultra settings at 60 FPS on 1080p, while being quiet and small. After overclocking my GTX 970 a bit, I think I have succeeded. My budget originally was about $900, but seeing some of the sexy hardware out there, that ballooned up to about $1300. Since I'm in Japan, a lot of parts I wanted either weren't available or were too expensive. Some of the parts I settled on had to be shipped from the US.
This was my first build and I learned a lot. Cable management is really difficult. I tried my best but hopefully will do better next time. I overclocked the CPU to 4.5 GHz along with the GPU and it's still very quiet while gaming except for coil whine. I really think the Phanteks fans are great, though to be honest I don't have anything to really compare them to.
I was really worried this would add noise to my system. I had a cheap Rosewill low-profile cooler on for a few weeks but decided to go ahead and order the H100i GTX for overclocking. Honestly it is kind of overkill. It lowered my CPU temps by about 20C or more, even after overclocking. It's dead silent while playing games, too. The only problem is the Corsair software is not so great, but it's adequate.
Had everything I was looking for in a motherboard. The only compromises are the internal USB 3 connection is placed in a bit of an awkward spot (not a problem if you go with water cooling though) and there is only one system fan header which supports 0.5 amps (x 12 volts = 6 watts). That was just enough for me to daisy chain 3 case fans off of.
I was able to overclock this card another 130 Hz before Valley started throwing fits. It's a nice card, and the fans are quiet, but the coil whine almost made me return it. After burning the card in over a few days the noise has been reduced substantially, however, when gaming it is still by far the loudest part of my system. Honestly it's the only part of my system I can hear, ever.
This case has made me into a bit of a Phanteks fanboy. I love the styling, the features, the build quality and even the price. I wouldn't say it was a "pleasure" to build in, as it is still somewhat cramped at this size and with all the stuff I crammed inside, but I don't know if there is any case this size that would have done any better.
The 200mm intake fan it comes with is super quiet and just looks so cool, as well.
I had no problems with internal temperatures (in fact they seem to be quite fantastic), but I did preempt any possible problems by choosing an nVidia card, installing 5 case fans and using water cooling on the CPU. IMO: build smart with this case and you shouldn't have any cooling issues.
The removable radiator tray at the top is useful not because you can remove it (with the H100i GTX you really can't remove it once installed), but because you can slide it halfway out to get access to the rear panel. Really useful if you need to route some cables or anything.
The only thing that might've made this case better for me would've been an included fan hub/controller. Oh, and it should have come with 4 more long screws for the front fan brackets. As it is now, I have each fan screwed in on two sides only.
Dead silent and working fine as far as I can tell. I don't like the stiff, flat cables though, but I guess that's personal preference.
They're absolutely silent in my case.
Pretty much as quiet as you can get. I never hear them.
