Edit 03/31/2018: Finally tried an overclock and was able to get it to 4.6 GHz so far. Left all settings on default except for all cores to overclock at a 46 multiplier. Voltage is auto, so the monitoring is showing that it goes at 1.240-1.265 volts. 48 multiplier flat out blue screens at boot and 47 blue screens on a stress test. When stress testing it by itself it goes up to 67 ° C and about 78 ° C when stress testing with the GPU.

Since the last update, I've changed the case fans for the Noctua industrial ones. This greatly made things much quieter on idle so basically, it is just the 212 EVO that makes the most noise now. I do plan on changing out the CPU heatsink one day when I want to tweak with the voltages to get higher overclocks.

Edit 11/30/2017: Monitor finally arrived so new images and updated Parts List. The only thing left is to wait for the UPS and new Displayport cable as the one that came with the monitor broke... It is a refurbished monitor that doesn't seem to have any issues besides the broken cable and scratched monitor stand so I am willing to pay for a new cable for a 40% off monitor :)

Pictures will be up in a later time. They will only be pictures of the system through the windowed panel of the Define C until I decide to take apart the PC again to take pictures of everything.

A nice little system that I built after deciding to pawn off my old PC to my family.

The operating system is actually Windows 10 Education, which has all the features of Windows 10 Enterprise except for ReFS support. It's not under any subscription so I can keep the operating system even after finishing school. One nice perk about university I suppose.

One of the m.2 SSDs are for the operating system and virtual machine needs and the other for applications and games. Virtualbox and Ubuntu Bash are quite annoying to move to other drives other than C: so I can't be bothered to make the C: drive be used solely as the boot drive...

There are actually 2 more MX300 m.2 SSDs in the system, since I have access to many HDDs and m.2 drives for free. They are hooked up into the system using m.2 to SATA adapters. They will likely be used for my games and other fast storage needs in the future when. It is quite unfortunate that when you create a spanned volume out of SSDs, they lose the ability to perform TRIM... It's probably not a bad idea to buy m.2 to USB adapters when even those SSDs are filled up :D

The 2 HDDs are configured in Intel RST Raid 0.

I may consider overclocking the CPU a bit in the near future. Right now, I am doing nothing that requires high CPU usage, so the stock speeds are good enough. Being that the temps for the new 8th gen Intel CPUs get pretty bad without delidding, I rather not do any good overclocking until the warranty is used up. By then I can (almost) delid without any qualms.

My only real regret is that the motherboard doesn't have any USB ports that support USB 3.1 gen 2. Otherwise the ASRock - Z370 Killer is the perfect motherboard that fits my needs.

Part Reviews

CPU Cooler

It's cheap and it works. My i5-8600k stays at around 30-33 C when on idle using this cooler.


Fantastic Motherboard at a great price. 2 m.2 slots that can be used with m.2 SATA, wifi, and 2 pcie 16x slots. The only real gripe and why this gets a 4 star review is that it does not have usb 3.1 gen 2 slots.


Love this case. The exterior design is fantastic as expected from Fractal Design. The insides have the perfect amount of space to fit everything you want. Cable management is a breeze with all the little holes and grooves to fit cables through and bundle them in. It has just enough of everything and nothing in excess.

Power Supply

80+ Gold, 650W, and semi-modular for under $90? Yes please.


Fantastic mouse with the extra buttons in the perfect positions. Not too many extra buttons so great for all games except for MMORPGs like Warcraft. The weight tuning is a great addition too, but I do not use them nearly enough.

Hey, nice build. Was wondering about your 8600k temps with the Evo 212. When you say under load what are your running? CPU heavy games or just tonnes of excel?


Percutio submitter 1 Build 2 points 15 months ago

Under load meant when I was playing games and ran a few quick stress tests. Until now I didn't run any stress tests very long but this time I kept it on for more than 10 minutes. HWiNFO shows that maximum temperatures for both individual cores and CPU package reach 56° C. Average CPU package is 55° C. The new picture will show the screenshot with this data.

I forgot to add the Thermal Compound previously so now I did. I'm using the Arctic MX-2. I chose this solely for the fact that it seemed to be the best of the bunch that was going to ship in one day using Amazon Prime. The Evo 212 was also one day shipping but I didn't know at the time that it comes with its own thermal compound.

How you liking the Define C? How are the temps under load?

Percutio submitter 1 Build 1 point 15 months ago

Temps when playing Rise of the Tomb Raider can get about 70° C and 60-65° C average for the GPU and CPU respectively. From what I've seen Rise of the Tomb Raider doesn't use the CPU all that much so I expect the temps to change somewhat when stressing both PUs at the same time.

The Define C is pretty good. My review tells most of my story with it.

Have you tried overclocking your cpu yet? I'm curious to see temps for that cpu with 212 evo while overclocked.

Percutio submitter 1 Build 1 point 15 months ago

Not yet, but even when I do overclock I'll probably just do it modestly. An overclock to the limits will have to wait until I decide to de-lid and replace the TIM inside or actually have a need for a very powerful CPU.
