Hey all, finished my build this weekend and thought I'd share. Thanks to HyperActive for pointers on fitting the strix!
CPU: AMD Ryzen 9 3900X 3.8 GHz 12-Core Processor
Cooler: Noctua NH-C14S 82.52 CFM CPU Cooler
Motherboard: Asus ROG Crosshair VIII Impact Mini DTX AM4 Motherboard
Memory: Crucial Ballistix Sport LT 32 GB (2 x 16 GB) DDR4-3200 Memory
Storage: Crucial P1 1 TB M.2-2280 NVME Solid State Drive
Video Card: Asus GeForce RTX 2070 SUPER 8 GB STRIX GAMING Advanced Video Card
Power Supply: Corsair SF 750 W 80+ Platinum Certified Fully Modular SFX Power Supply
Since the initial build, I've installed a Noctua 92 mm slim fan at the back. At stock clocks, but with PBO enabled and AOC at +200MHz, I'm seeing idle temperatures at 44 degrees according to Ryzen Master. Temperature at load is 82 degrees with average CPU clock at 3966 MHz and peak at 4492 MHz in AIDA64. Probably seeing some thermal throttling here, as there seems to be an improvement of clock speeds as the temperature goes down.
If anyone has any ideas on how I can get my CPU temps down further, please share!
GPU idles at 36 degrees. The CPU fan is running at 800 RPM or so exhausing out of the case. The GPU fans are running a tad under 1000 RPM.
A few assembly notes:
Cables:
The entire build is done with the stock cables that came with the SF750. The 24 pin and CPU headers are right next to each other on the Impact, which makes for some clean cable routing. The PCIE cables unfortunately have pigtails which take up some extra space and don't look so neat at the GPU. There is barely enough space to route them around the GPU and get the case to close. The spaces underneath and on the motherboard side of the power supply are just sufficient to bundle all the cables up and squeeze them in place. It's not shown, but I also have the SATA cables routed to the front so I can add secondary storage later.
Headers:
If you're planning on using the C14S, plug in all your headers before you install the GPU. If using the RGB headers on the motherboard, make sure you plug the cable in before you install the GPU because they're right underneath. Otherwise, you can use the other RGB header on the SO-DIMM. Also be aware that the CPU fan header is in between the CPU and GPU. This was very hard to plug in since I decided to install the fan after the GPU and cooler were already in place.
