Is sufficent 600W?
Zalman CNPS 10x is noisy? Should i change for a cooler master hyper 412s? @Hunter!
It can become noisy. In my opinion if i were you i would get the cooler master fan as i'm using one atm and it has a big airflow stability and it doesn't make noise at all. About the Powe Supply.. 650 Watts.. Humm i think a 650W PSU can handle it doe if i were you i would get a 700/750W PSU in case you wanted to upgrade the cpu or something.
If you need help with anything, feel free to PM/VM me about it.
