There is a self heating failure mode for capacitors that would depend a little bit on current drawn, but the voltage across a cap would be constant regardless of current drawn so safety and fire related failures are primary based on time. "Name Brand" products with legitimate UL listings almost entirely use Class X or Y caps where safety regulations require them and would be immune to this problem due to internal construction differences. "No name gray market off aliexpress" would be an unwise choice. It's surprising how few fires we have from household electronics. The odds are it'll be fine.
