I am also running the Sparkle A310 eco and just like @Erick_Gruis I use it for Jellyfin transcoding which does work at the same time as intel_gpu_top.
As he mentioned you should update the GPUs firmware (I linked a method here and others also described how they did it) - in you case I would even recommend it if you currently don’t have any fan issues.
If transcoding works fine until you start intel_gpu_top I don’t think your hardware is actually bad (although I also don’t know why a driver/software error of that kind would only show up for you).
