This build is quiet and works well for very high res Photoshop and illustration work, gaming, CAD, animation, video rendering and multitasking. My reason for going with a hex core over a higher frequency quad core was for the extra ram, which I often use more than 40gb of, and better multi streaming capabilities for rendering and multitasking. My Adobe program files, games, media and OS are kept on separate hard drives to increase performance without using a raid setup. A 120gb scratch disk is dedicated to Photoshop. I’m satisfied with the Corsair H90. It cools remarkably well even with the fan speed set as low as 800rpm. I considered the Corsair H110 and the H100i; however, as I wanted a silent computer, I opted to keep the top vents closed and only use the rear fan slot with the H90 as exhaust. With two intake fans in the front and one on the bottom I have a positive pressure build which creates less dust. This actually works way better than I anticipated, even with my GPU venting into the case. The build went without a hitch everything is very stable. I have not needed to overclock as my processor has more than enough power to handle anything I throw at it. I'm sure this system can handle a slight overclock should the need present itself. The MSI GTX 780 gaming edition is one of the quietest high end GPUs on the market and cools extremely well. I did not go with a workstation card as the price to power ratio is beyond my budget. I don't need 10-bit color. The 780 does fine for what I want to use it for even if it's not the best in slot option. It's also much quieter which is very important to me. The Define R4 case cools well and is quiet as advertised. Some people complained that the HD mounts were plastic and junk. Mine came with heavy duty steel ones so I must have a newer revision or something. The loudest thing in my office is my buzzing monitor. I think it’s PWM circuitry is going bad.
There are some negatives. The AI suite software that came with the Asus x79 motherboard for managing clock settings and fan speeds in windows will not install. The bios works OK though so it’s more of an inconvenience than a real problem. The MSI GTX 780 whistles sometimes when rendering extremely high frame rates. Using V sink fixes that. My old GTX 260 whistles much louder in such situations. My old system was loud so I never really noticed it whistle much till I tried in my new quiet system. My semi passively cooled PSU has a fan that will spin to full at times when it gets hot, rather than running at a low RPM like it’s supposed to. The Blu-Ray player is a bit noisy; however, it and it's included software works fine.
My temperatures may seem abnormally low to you. My room temp is a cool 21c so I assure you it's correct, at least according the CPUID HWMonitor.
I plan on modding the PC with some led strip lighting. Anyone have any suggestions for that? Have you bought similar parts? What was your experience with them?
