Re: new tower fans
I wouldn't worry about the PSU so much, although the PSU's in prebuilts like HP's and Dells can be extra craptacular.
A computer case isn't exactly airtight. Air will sneak in/force out of all kinds of holes and cracks you probably don't even know are there. Ideally what you want is equal flow into the case and out of the case in as linear a motion as you can get, either front to back or bottom to top (chimney effect). That would give you the best results cooling wise. |
