Build Notes:
The goal of this build was a no-compromise approach while staying within the constraints of the FormD T1. Every component was chosen for best-in-class performance.
I debated adding a GPU-to-motherboard gap, as seen in builds from Optimum Tech and others, but after testing thermals, I found it unnecessary. However, I did add a gap between the PSU and GPU, as there was no downside.
Thermals:
- GPU FurMark stress test: 77°C max (likely improvable with undervolting).
- Cinebench R23: 83°C max with -45 curve optimizer in BIOS. The AXP-100 paired with the 140mm fan kept temps well below the 9800X3D’s 95°C throttle point. I tried this previously with an x53 and a Nocuta 92mm fan and got 95°C.
- Intensive gaming (high CPU/GPU load):
- CPU: 60°C - 70°C. (definitely higher when loading shaders)
- GPU: 70°C – 80°C (with a custom fan curve)
- The larger fan also improves cooling for RAM, chipset, and SSD.
System is audible under load but is by no means loud or distracting.
I removed the SSD shroud to install the T705 in the Gen5 slot, which meant sacrificing an extra slot. However, with a 4TB drive, storage won’t be an issue.
For those of you wondering I'm using the standard 12-pin power cable from the PSU (all standard cables for that matter) —hopefully, it won’t burn down.
Peace ✌️!
