CPU: 9800x3d or 9850x3d for a SFF build?

I’m building my first ever small-form-factor PC this weekend, and the last decision I need to make is the CPU.

I know the 9850 performs better, while the 9800 is more efficient and runs cooler.

How have people found the 9850 in SFF builds? Does it require extra careful thermal management above and beyond the 9800?

Case: nCase M3 Grater
PSU: Corsair SF1000
CPU: 9800x3d or 9850x3d
GPU: ASUS ROG Astral RTX 5080 OC
MB: ASUS ROG Strix B850-I
Ram: Kingston Fury 64GB (2x32) CL30
SSD: Samsung 9100 Pro 4TB
Cooler: Noctua NH-D15 G2
Fans: 3x Noctua 140, 1x Noctua 120 (Rear intake, top and front exhaust)

We recently welcomed an eight week old Spoodle puppy, and found a ‘whelping box’ to keep it safe in our apartment early on.

The pen was very small and didn’t fit our space the way I wanted, so I began printing custom parts to get it just right.

As we learned more about the joys of puppy ownership, the pen quickly needed to evolve: Hiding the edge of the grass so it couldn’t chew, holding the door open so it didn’t lock itself out of the crate, securing the crate to the walls so it couldn’t push it out of the way, and most importantly… making the walls progressively taller so it couldn’t escape.

The puppy quickly outgrew the initial size of the pen, so in addition to the pen getting taller… it also got wider!

Over time, I estimate over 50% of the pen is now 3D printed:

- Matching uprights to make the walls taller
- Pipe-sized connectors to fit PVC pipe for a material-efficient wall solution
- Custom walls to wrap around obstacles (wooden upright)
- Actual wall pieces
- Slot-in floor ramps to keep the walls straight + cover the edge of the grass
- Locking mechanism for the crate door
- Post end caps
- Loops for Velcro where the crate door opens
- Post-end camera mount

* It probably would have been easier and cheaper to just buy a larger / taller pen from the beginning, but it wouldn’t have fit our space as well as this does, wouldn’t have been modular for a range of configurations, would have lacked features like the camera mount / door lock, and I would have struggled to combat the various challenges over time as the puppy found more and more vulnerabilities.
