Sorry for the crappy camera photos.
Updated my gaming rig that I built last year that ended up becoming my Do Everything Rig - http://ca.pcpartpicker.com/b/zJw
I wanted something a bit smaller and quieter which didn't heat up the home office as much. I replaced the stock cooler on the GTX 680 with an Arctic Twin Turbo II, which brought the GPU temps and noise way down, but I was still in a behemoth of a case.
Ditching the Corsair 600T, I tried out a Cooler Master HAF XB first. It was small, but the open-air design left it a bit dusty and noisy for my liking. I'd swapped out the stock fans on the H60 for Cooler Master Excaliburs, but they were a bit whiney at high RPM's.
I ended up settling on a Fractal Design Define R4. The appeal of the case is that it's noise-insulated, while still having room for adequate cooling and the rest of the parts I've acquired over the last 18 months.
While moving over to the new case, I changed the cooler from an H60 to an H100i, and the XFX 750 power supply for an EVGA NEX750G modular power supply to help with cable management.
Front-mounting the H100i with 4 SP120 High Performance PWM fans was a bit tricky, but ended up working out pretty well. My 2 SSD's are mounted on the backside of the motherboard tray, and my 3.5" is in a 5.25" slot.
I changed up my audio a bit, going for headphones (went through Razer Megalodons, Siberia V2s, some Logitechs before settling on the Razer Carcharias) and a ASUS Xonar DGX soundcard to power them.
On the monitor front, I ditched my Samsung 27" for a QNIX 2710 2560x1440 display, which runs nicely at 120Hz. The GTX 680 is overclocked to 1.2 GHz core and 6800 MHz memory, and plays all the games I like on ultra (Skyrim, WoW, Rift, SWTOR).
I decided to freshen my peripherals as well, going green with Razer Orbweaver Stealth keypad, Razer Blackwidow Ultimate 2013 keyboard, and a Logitech G600 (because my man paws make the Naga feel small). Add in some glitz like the Razer mouse bungee and the Razer Goliathus ridiculously large mousepad, and my battlestation feels pretty good!
I'm running the fans through Corsair Link in silent mode, so they stay around 900 rpm, even under load @ 4.7GHz. Ambient noise in the room is about 30-32 dB, and putting a meter right up to the front or back gets readings of 34dB. Pretty quiet. Taking it up to 4.9 GHz, the fans have to run about 1400 RPM, and we go up towards 38-40 dB.
Honestly, at this point, OC'ing over 4.5 is less important to me than a quiet system. I've found a happy middle ground at 4.7, and nothing seems too warm - I top out around 60 C in Prime95 testing.
Any suggestions on what to do next?
