x. Is it safe?I'm waiting for new case (Cooler Master Haf-X),my current case is crap no additional coollers,nothing,then i will see what the temp will be.
Air no! Water yes! If you have a temperature spike you'll burn one of the inductors or mosfets!
Keep your voltage to a 1,24V minimum on air!
You see, voltage is the electrical potential for a circuit to work, If a circuit has voltage, it has electrons ready to flow, now, current, measured in Amps or Amperage, is the flow of electric charge.
When electrons flow, the movement of those electrons is measured in amperage and its that current (power draw) you increase when increasing the voltage, thus increasing the heat!
As a graphics chip is dynamically loaded by programs (games, benches, scientific software) in any particular time (could or could not happen), a power spike during a very high load (1 second is enough) will lead to a heat spike, your cards cooler will not be able to absorb all that heat (centered in such a tiny spot) and that electronic part will burn!
Burned inductor (Choke)
As there is no temperature sensor in these reference PCB´s, by rule of the thumb the VRM´s are 20/30C above core temperature but some of its components operating temperature is 85C Max!
