Hello people!
This is my first post here

I do have some knowledge about BTC and altcoins, but I cannot understand at all how to mine it!
I do have Cudaminer, but I have overheating problems (99celsius, it's sick and unsafe). Is it possible to force my GPU to mine on let's say 50% usage? I don't mind for the amount and I know that thic GPU sucks for mining, but... I just want to mine 50% with what I've got.

I'll be grateful for feedback
