My current workstation is as follows:
PSU: SeaSonic SS350ET 80+
MB: ASRock Z68M/USB3
CPU: Intel Celeron G 530, 2.40GHz, 2MB, LGA1155, 32nm
RAM: 8GB = 2 x Good Ram DDR3 4096MB PC1333 CL9 (GR1333D364L9/4G)
SSD: Crucial M4 CT128M4SSD1CCA
Case: old noname fullATX got somewhere for free
CPU cooling: Scythe Ninja 1 fanless
I have two questions:
1) I would like to exchange my CPU for a better one, i5 or i7
at least and still remain silent. Please advise me the best possible CPU (power-wise and power/value-wise) for LGA 1155 socket, that can work fanless on my setup. Here's the list of all supported CPUs: http://www.asrock.com/mb/Intel/Z68MUSB3/?cat=CPU
I do not plan to install any video card at all, ever, so I don't think changing PSU is necessary. But...
2) My PSU (SeaSonic SS350ET 80+) started to work a bit louder. I can hear whining sound coming from it, like if the fan bearing wore out. Is there anything I can do about it? My PC is about 1.5 year old.
