It's been a while since PALIT released their passive cooled GTX 1650 KalmX and I haven't seen anything comparable with "next gen" performance. Of course you could put an RTX 3080 in a MONSTERLABO, HDPLEX or TUREMETAL case but if you prefer to have a standalone, passive cooled GPU for your custom build there aren't many options...
long story short, here is my DIY solution to turn the RTX A2000 into a passive cooled "KalmX Edition"
Specs:
performing the mod:
besides the A2K and the ACCELERO S1 cooler, we need a 3mm copper plate for mounting and covering the VRAM...
the copper plate will be soldered with 138C solder paste to the heat sink...
I am using a small, cheap "Pizza Oven" for this job and controlling the temperature via a temp probe... the process is a little bit tricky because if you heat it up too much, the heatpipes will come loose from the cooler itself...
as soon as the solder paste melts you're good and can stop the oven...
last but not least I painted the modded heatsink with some temperature resistant spray paint...
mounted to the A2K with two M2.5x8mm screws and done...
next up, some benchmarks...

Specs:
- GPU: RTX A2000 6GB
- Cooler: ACCELERO S1 R2 & CNC machined copper plate
- Dimensions: ca. 2 Slots, 135mm height, 220mm long
