For this build, I wanted to focus on silence, hence the Noctua Air Cooler and Fractal Define R5 Case. I also wanted to have a good upgrade path, and be able to overclock non-k CPU.
I have the i5 6400 running at 4.2 with vcore of 1.3. Stable at full load and temps are around 30c idle, and 60 load with the Noctua Cooler.. I also tried clocking up to 4.5 with same volts, it was stable ran prime all night. but temps got to 65c at load, so i backed it down to 4.2. Not bad for a $180 CPU, runs like its more expensive siblings.
The current most up to date bios on the ASrock Z 170 Extreme 4 board supports bclk overclocking. The board has a toggle switch with 2 bios, so i have a beta bios from overclock website on # 1 bios, and I have the current bios from Asrock on # 2, both of which support bclk o/c on non -k.
The only con for overclocking non k CPU is that C States have to be disabled, so you cant put PC to sleep, you can use a screensaver or turn it off and reboot, but no putting to sleep or it locks due to C States Disabled, You also have to disable thermal throttling, and some temp reading programs will read 100c all the time. the ASrock bios, and ASRock windows utility does display the correct temp, just not CPUZ.
i was originally going to go with a closed loop cooler, but decided to go with Noctua since it is quieter and as good or better than a close loop cooler.
The RM 650 PSU was chosen because it is one of the quietest PSU on the market, and has a gold rating, and is modular. ASRock Z 170 Extreme 4 is at a good price point for the features you get, 1150 audio sounds great, has m2 port for future upgrade, had SLI, has good michicon capacitors, and VRAM sinks, and the color scheme looks great, something different besides red/black, or blue white.
The Fractal Define R5 is the best case I have ever worked with. love the dust filters and look of the case. super quiet. barely audible under full load.
GSkills Ram works at the rated speed of 3,000 while CPU is stock, and I run at 2600 when overclocked.
The EVGA SSC GTX 960 is a card i had in my old system, so i am using it until i get a 1440p panel. GTX 960 is great for 1080p, i can play everygame at ultra on 1080p with this set up and get 60fps and my roommates dont complain about the computer sounding like a jet engine while i am gaming lol. Hopefully by the end of the year, i will be able to get a 1440p panel and a new 1070gtx.
Would love to hear comments on what you think of my build. Will post pics tonight
