Are Cooling stand worth worth

Any cooling stand will do nothing to help cool the system,and actually can help them die by changing the static pressures inside compromising cooling

The system is already designed to cool itself and does not need any external devices, which can invalidate your warranty

Thank you where's the best place to put the house hold fan near the xbox

they will actually break the console in some scenarios. they can help move air if you are in a hot environment and the air is static, non moving but would be better to just use a household fan to move air around the room making sure the console is free on all sides.

like i have said, just make sure there is air circulation in you room and you are fine.

Apparently blows air into the xbox from the bottom
