Limiting GPU (Underclocking)

[wintherr]

I want to limit my GPU while i play certain games, such as Skyrim etc.

I want to underclock / limit my GPU to render X number of fps.

Can this damage my GPU, if no, how could I limit my GPU effectively.
Thanks in advance

EDIT: I've tried limmiting the fps using Dxtory, but since calculations still ran in real time, that solution did not work.

well you can lowers the power target of the GPU that will decrease not only the temp it will increase more the life of your GPU
it wont affect any damage and all
