I have an Alienware x51 which is an extremely small box with everything crammed inside. I recently upgraded my graphics card to a GTX 750 ti superclocked ( a mistake in hindsight ). Now I have realized this card is much too hot for my tiny case and I have to leave the case open with an external fan pointed on it whenever I play graphics intensive games. My question is, If I upgraded to a bigger card with a double fan (connected to a power supply rather than a PCI powered fan) will this solve my heat issue? If so, can anyone recommend an economical double fan card that would be compatible? Hoping to spend less than 150 bucks.
