The idle temp is great ! Just like my temp when it is idle.. I opted for watercooling bcoz of the hassle of cleaning the dust once in a while.. LOL laugh.gif

i just wanna ask..i just found out that the default core voltage in ccc profiles for default setting for the 4850 is different although same brand.
my fren's:
<Profile>
<Caste name="Graphics">
<Groups>
<Group name="Overdrive5">
<Feature name="TimeUnlocked" />
<Feature name="OverclockEnabled">
<Property name="OverclockEnabledProperty" value="True" />
</Feature>
<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="16000" />
<Property name="Want_1" value="50000" />
<Property name="Want_2" value="62500" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="50000" />
<Property name="Want_1" value="75000" />
<Property name="Want_2" value="99300" />
</Feature>
<Feature name="CoreVoltageTarget_0">
<Property name="Want_0" value="1046" />
<Property name="Want_1" value="1046" />
<Property name="Want_2" value="1123" />


and this is mine:
<Profile>
<Caste name="Graphics">
<Groups>
<Group name="Overdrive5">
<Feature name="TimeUnlocked" />
<Feature name="OverclockEnabled">
<Property name="OverclockEnabledProperty" value="True" />
</Feature>
<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="16000" />
<Property name="Want_1" value="50000" />
<Property name="Want_2" value="62500" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="50000" />
<Property name="Want_1" value="75000" />
<Property name="Want_2" value="99300" />
</Feature>
<Feature name="CoreVoltageTarget_0">
<Property name="Want_0" value="1046" />
<Property name="Want_1" value="1046" />
<Property name="Want_2" value="1082" />


i also noticed that my temp is lower although in same environment.is the core voltage for each card is actually differs like cpu vid?
