I would suggest the fan is faulty, sounds like it is drawing way to much power, and may even be short circuited causing the system to protect itself and shut down. Reconnect the old fan again and if it works that will prove it.

Gday.

Not sure I am reading your description correctly.

The top fan header is only for the CPU heatsink, if you remove it, the CPU will over heat and shut down the computer.

It is very unusual for a case not to have a rear exhaust fan and it should be plugged into the fan header on the left side of that MB.

A front intake fan should be plugged into the socket on the right/front header on that MB.

Well plug the new fan into the socket the old fan is working on and try that, that will tell you if the fan is ok or not.
