This weekend, I picked up my first desktop. I've been looking for one for a while but at the moment don't have the means or the time to build one. I found a factory-refurbished HP that comes with an AMD Phenom II X4 processor, 8GB of RAM, 1TB hard drive, and an AT Radeon 4350. The most demanding thing I'll be using this for is Photoshop CS4.
Not having owned a desktop before (only laptops), I don't have a point of reference for how much noise a desktop should make. Some reviewers stated that this particular model is very quiet. When on, I can certainly hear it -- a low-level hum/noise, which I'm assuming comes from the fans, though I'm not certain if it additionally comes from something else.
So here's my very basic question -- invariably, desktops will produce some noise that's fairly constant, correct? And I should only be concerned if the noise is excessively loud? Any suggestions for "problem" noises to listen for?
Thanks for your help, and sorry for the newbie questions.
