I can state with certainty that the V10 has very high build quality and I don't see any reason for any early failure. The TEC is not a high powered unit and it does have it's own 4 heatpipes to keep it cool. Also, the V10 does have the built in variable controller to only push the TEC when it needs to otherwise it cuts back on the power delivered to it.
