Basically if you can't do it with those applications, it's not possible (ok, if you are an electrical engineer, sure).
I had this same problem with my x1400, didn't budge.
Actually my idea is to underclock this card. You are right that they tend to go too hot.
It is pity that BIOS prevent to change any of this options (other way it goes automativally in three modes - 2D (100/100) 3D low power (200/300) and 3D performance (375/500).
The problem is that even when I simply watch movie it goes to third mode and heat up to 78-80 degree. (It is not very cool in normal mode - 60, but anyway it is better than 80).
