Does your card have a 3pin fan adapter on it? Mine does, but I'm wondering how useful it is. I am thinking of getting one of those Thermaltake GF4 cooling kits and I would like to plug the fan into that header, but I'm wondering how much power it can handle, will it make the card unstable, etc. etc. So my guestion is, any of you that own this card, have you used the fan header? TIA.
