My criteria for this build: I wanted an AM4 system that could comfortably fit the Dark Rock TF that I paid way too much money for and a graphics card that I could remove the shroud from and use only bottom exhaust fans to cool. I wanted to avoid having to buy/put together an Arctic Accelero while reaping all the benefits.
Other thoughts: I didn't feel satisfied until the 1080 Ti was in there filling up all that extra space. Everything fits like a glove on a case that was surprisingly easy to work with due to its light weight and ability to take off ALL panels. My plan for GPU cooling worked out wonderfully and the thing is silent at idle and sounds...smooth? under load. However, CPU load causes some coil whine (??) near the CPU area, and the GPU has quite a bit of whine under load as well. Not as much as my R9 Nano, and every GPU I've ever owned has had coil whine, but I had my fingers crossed. I don't understand how these reviewers are claiming to hear no whine at all!
Ryzen 7 1700; was on sale on Amazon for 269.99 and I couldn't pass it up. In retrospect I would have preferred a 1700X but I also needed the Spire cooler to tide me over while I waited for the Be Quiet! bracket to arrive (~2 weeks). Overclocked to 38.25x multiplier at 1.3625V; not really looking to go any higher since temperatures really spike up past 1.3625; difference between idling at 650 RPM and 900 RPM with the curve I set. Never goes above 75 under load with a really passive fan curve on the TF.
I knew of the horror stories surrounding this board's VRM temps and I went with it anyway because the cooler clearance on this thing is legendary. Due to the AM4 bracket shape and the power cable in the corner my Dark Rock TF only fits on one way, and there is less than a mm of space between the lower heatpipes and the RAM. I could have even gotten taller RAM (such as Samsung B-die, darn). The top fan of the TF is actually zip-tied to the side bracket for a cleaner shot at the VRM heatsinks and controlled by the VRM temp; dropped VRM temps by 10 degrees, but still hitting ~110 under Prime95.
SK Hynix Single-Rank running at 2933 14-18-18-18-34 after tweaking a bit. Will not boot at 3200 regardless of latency, but I don't know much about RAM overclocking. There have been 4 BIOS updates already since I got my board, so hopefully this bodes well for future compatibility.
Originally an R9 Nano; still noisy at idle and made even worse by its new spot on my desk. Tried to mod the fan (terribly) which silenced it, but the NF-A9x14 spins at less than half the RPM and could not prevent throttling. Finally caved and bought the ASUS Strix 1080 Ti, which was my original plan for this build; the 2.5 slot design means that with the shroud removed, there is only 1-2 mm of space between the two Silent Wings 3 in exhaust right below it.
I knew for a fact that the Strix 1080 fit; I triple checked all over the place to make sure that the 1080 Ti was the same length and width, but I was still real anxious, especially with Newegg's replacement-only return policy. The rear side panel mounting clip is less than a millimeter away from the upper left corner of the PCB on this thing. Close shave.
SF600 was deemed the quietest and I didn't want to go SFX-L. Still modded the fan with an NF-A9x14; very easy mod to do and requires this adapter, although in hindsight I could have shocked myself poking around (and the warranty is probably shot). It is now even quieter, although again, the Noctua is pretty low RPM and I still don't know if that will be a problem. So far so good under heavy stress test for 12 hours.
I was also interested in the Strix for the FanConnect 4-pin headers, but I could not get GPU fan control software to change their fan curve. GPU Tweak would only adjust the PWM of the mini header used to control the original fans; fortunately, this adapter, that I was originally using with my R9 Nano mod, worked fine.
The two 120 MM Silent Wings (high-speed, model BL068) on the bottom are mounted in exhaust, each connected to a Noctua low-noise adapter, connected to a 2-way PWM splitter, to the VGA adapter, and finally to the card's mini fan header. In retrospect I should have gotten lower RPM fans. Right now even with the low-noise adapters they are running at 10% PWM at idle and 33% under load which keeps the 1080 Ti under 80 C in Furmark while staying soooooo quiet.
