Description

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

Nice build, but I think your CPU cooler may be 180degrees out? Is the fan pulling air towards the rear, or pushing air towards the front.

You want it to be pushing air out the rear exhaust for best results!

I put my hand in there to check, and it is blowing air to the rear exhaust.

hey, you were right about the CPU cooler fan not being orientated correctly. I thought it was pushing air towards exhaust, but it wasn't. That's what happens when you get baked and put together a gaming PC lol. Anyway, i moved the fant to the other side so it is pulling air through the cpu cooler block vents, and pushing through towards the exhaust. idle temps are improved now @ 28c. I added 1 more intake fan on the front, so it is positive pressure system 1 exhaust, 2 intake.

I played through Doom last weekend and the performance was amazing on this thing, even with the measly GTX 960 card. When the 1070 comes out in June, i am going to put that in, and probably get a 1440p monitor too, provided a 1070 can handle it.

"Overclock non k CPU"

Whut?

you can get huge overclocks with skylake non-k cpus on the right board and right bios. Prior to skylake, the cpu bus speed was tied to system bus, PCI-E, memory, etc, and so even a small increase in the bclk would cause instability, so it wasnt worth it, no the cpu bclk speed is not tied to anything, so it can be cranked way up and not cause instability. There are tons of articles on it, and its actually really easy to do and can even be done on the lower end H series boards, but i would recommend getting a z 170 board as they are the only boards that allow memory to run higher than 2133.

Does th non-k overclock still work?

Yup, just need a Z170 motherboard and the old BIOS for it :)

yep. It still works. I know there was a lot of hype on the internet about Intel forcing microcode, but I dont think it ever happened, or ASrock didnt implement it. The ASrock board i have has a toggle with 2 bios chips, and i even flashed one of them to the lastest bios, and was still able to o/c. I run mine @ 4.2 GHZ with 1.3 volts, and it stays around50- 60c while gaming with a decent air cooler. you can do 4.5ghz at 1.3 volts also provided the silicon lotto is good to you. The only drawback i had while o/c is that i cant use C-State. So be sure to disable those in bios. otherwise it will lock the PC at times. C-States and also thermal throttling, as temp may be read incorrectly by certain programs.
