I just built a completely brand new system so I'm not sure what to expect. I first ran my desktop without the HDD just to test things out. Even with the fans running it was pretty silent. Once I installed the HDD and began installing Windows, drivers, etc, it's pretty loud. It also makes ticking/clicking noises? I am running a Hitachi 1TB 7200 rpm, sorry but I'm not sure what cache it is. Thanks in advance.
