It's been 13 years since I built my last gaming rig. I was posted overseas and decided to play games on laptops as I was moving around all the time. Now that I'm settled, I've decided to have a go at building a gaming rig again.
I wanted something that could run games smoothly at 1080p on ultra settings. I was going to hook it up to our living room TV, which meant that I'd be capped at 60fps since the TV runs at 60Hz. Reading heaps of reviews led me to the 1660ti, which seems to be the most bang for buck GPU for 1080p-1440p gaming at the moment. I wanted a small form factor build as well, since the rig's going to sit in our small TV shelf. Thermaltake's Core V1 seemed to offer a good balance between size and cooling.
CPU/Memory - Ryzen 2600 oc'd to 4.0 GHz @ 1.325v. Cooled by a Noctua NH-U9S, it averages 71c on an overnight Aida64 test. Memory's XMP sets it to 3400, 16-18-18-36 @ 1.35v.
GPU - Zotac 1660ti Gaming AMP oc'd using Afterburner to +150/+1500. Averages 61c on a 30 minute Heaven stress test.
Cooling - 1x140mm on intake, 2x80mm on exhaust. I also removed the stock AMD cooler fan from the heatsink and used it as a third exhaust fan. I attached it to the side panel through the vent holes using the spare PSU screws I have. That lowered the CPU and VRM temps significantly. All the vents (except for the back exhaust) are covered by Demciflex filters. I also removed the top plexiglass and replaced it with a 200x200mm Demciflex filter, which further reduced temps. The filters do their job well and the rig has been dust-free so far.
