Well, here's the scenario, you're building a computer for a customer: EPoX 8rda3+ AthlonXP 2400+ He's not a gamer - a movie watcher - a high-speed internet user - but he wants a computer anyway. I bought the retail version of the CPU as to obtain a warranty in case this guy has a habit of killing computer parts - however, on the warranty claim it says that the use of any heatsink and fan other than the setup that came with the processor voids the warranty. First of all: is this true? I bought a Zalman Copper Heatsink and Fan setup for the computer but to tell you the truth, it's louder than the stock cooling. Second of all: is the heatsink and fan that comes with a retail AMD cpu good enough? I mean, of course they're not handing out pieces of **** like candy down at amd, but this is for a customer who probably doesn't know the first thing about treating a computer right. He will probably put it in a very tight cabinet with virtually no air circulation, and I want to be sure that my cooling is good enough for it to never reach shut-off temps. As of now I have only installed the stock heatsink/fan and a single 80mm fan at the back (exhaust). What do you think?
