New Motherboard Issue. Gigabyte EP45-UD3R

[imported_Blaze]

I recently purchased the new gigabyte P45-UD3R. I have 2 computers that are both very similiar but the new one doesn't seem to run as cool as my last one

New System
Gigabyte EP45-UD3R
intel e2180 @ 2ghz
4gb ocz 800mhz
asus 4850
rosewill 500w psu
system temp - 45C
cpu temp - 30c

Old System
Gigabyte P35-DS3R
intel e2180 @ 2ghz
4gb gskill 1000mhz
msi 9600gt
rosewill 600w
system temp 30c
cpu temp 30c

Everything so far works great. Except for the fact my new system temperature at idle is 45 degrees celius. My cpu temp is good at 30c. I thought ultra durable 3 is supposed to operate cooler than ultra durable 2. Is there possible something wrong with the new board or does the p45 chipset run a bit hotter than the p35? Any comments or suggestions greatly appreciated. Are these temperatures normal and what is considers too high for system temp?
