I'm not really into buying a new cooler, you see this one is free

I have already thought about the Arctic Silver but if I am to buy that it will be by mail order, which will double the price..... What about standard cooling paste? Will that do/is that better than the thermal pad?
And about removing the thermal pad - do you just rip it off using force?
Btw. can anyone tell me the "standard" idle temprature on a 2000+? That way I could compare it to mine when I get it up running.
One last thing: The layer of cooling paste should be very thin right? Not just a large blob...?
I know it's kinda stupid to be a cheapsgate concerning cooling but I'm constantly broke due to two wheels and 746cc that I have in the garage....
