New Nas CPU - i5 Sandybridge, ivybridge, or i3 ivy?

[mstang1988]

Going to upgrade my NAS with a bit more storage using ZFS which is RAM and CPU intensive, especially once de-dedupe is more common and turned on in future freenas builds.

Fry's had an i5-2400 for $118 which got me thinking quad core but the TDP was high, can't decide if too high.

I have no need to overclock but may undervolt/underclock a bit to keep it nice and cool in an ITX case. Do I need to go with an unlocked processor to really have the last bit of control like a 3570K?

What's the real world difference between a 3450 and a 2400 in terms of heat in a small case?

I'm not disabling my gpu to run off igpu.

Ps plain thermometers not digital crap... The plain thermometer is using larger attached surface to the ambient and is always more accurate.

Instead of buying "digital crap", buy an FDA-approved digital thermometer. It will likely be much more accurate than dollar-store "plain thermometer".

On a good thermocouple digital thermometer, the size makes absolutely no difference in accuracy. The bigger thermocouples however have slower response time due to higher specific heat and may be more difficult to put into proper contact with the surface being monitoried.
