Built this computer as an upgrade for my old computer that ran on 4690K. The computer will be used for photo editing and gaming at 1440P 144hz. The most demanding game I play is probably R6S. I upgraded my GPU last summer from GTX 970 to GTX 1080 after I found newegg selling this one for ~550$ CAD.
I went into this build knowing that I'd overclock and I didn't want to use an AIO again (old build had Corsair H100i). Always knew Noctua were the best air cooler solution so I just went ahead. I also didn't want to do a black/white or black/red build, having done those already.
The D15 is absolutely huge and it covers alot of MB connectors and standoff screw holes. Mounting the spring loaded screws can be a bit tricky as well. You can mount the D15 after you install the MB into the case and set up the connections around it. The problem is that you would have some difficulty latching the fans to the cooler due to limited space above the cooler. Also, it would be nearly impossible to make fine adjustments to fan heights on the D15 to make sure everything is perfectly even. So in my opinion, the best way to do it is to hook up any connections near the D15 then mount it outside of the case. You will still struggle a bit with the standoff screws but if you have a very long screwdriver (longer than the one Noctua supplied), that won't be an issue. While the D15 fit inside Meshify C, I wish the case was slightly wider. If you don't care about colour, U14 is probably a better bet. You will also need low profile RAM to fit with D15.
Meshify C Comments
Probably the most expensive case I've used (last build used S340) and the qualify does come through. Alot of room for cable management, build quality is excellent. I think I'd rate it 9/10 but here's my complaints with it.
The front audio cable is not shielded and the cable will run past the PSU. This makes the front audio really terrible (buzzing + echoing), so I had to buy a USB audio adapter to keep using the front audio ports.
I wish there were more instructions. This is my 4th build and some of the time I'm still flipping through the instruction wondering "wat?". For example, manual doesn't demonstrate how to mount case fans, something first time builder will appreciate.
The 3.5 inch bays make cable management a bit difficult, especially with stiffer power cables. I wish I can remove the drive bay and still install one 3.5 inch drive. The instruction manual seems to suggest this is possible as a drive can be mounted using screws from below but as previously said, the instructions were minimal so I wasn't sure if that was the case.
I wish I can remove the front panel entirely.
OC and Temps
I know Gigabyte is supposed to have the best VRM's, which is why I went with them, but Z390 UD is still the cheapest model. Gigabyte's BIOS is not the easiest to use so it took a bit of learning. I'm currently running my 9600K at 4.9 Ghz and Cache at 4.6 Ghz. LLC is set to medium (as per buildzoid video's recommendation) and core clock set to normal with -0.02 V offset. During stress testing the temp goes up to 82 C with prime 95 and 73 with x264. During gaming it stays below 70. V Core max goes up to 1.32 as per HW monitor I did achieve 5.0 Ghz with my 9600K but it required v core to go up to 1.38-1.4 sometimes. Most of the time underload V core was around 1.35 V. The temperature were fine but I wanted to stay under 1.35 V core and I figured I won't notice any difference between 5 and 4.9 anyways.
