I have removed the side cover of cabinet, and low temps are in night, during day my temps are ~5C+
at 316*9.5 =3 ghz
idleing in day at 43-44C cores,
on load by prime, temps are 62C
these are on stock cooling and 100% fan usage.

I am sure i am gonna see considerable amount of change after i put in an aftermarket cooler. But since the ambient in my room is at about ~30C, it wont be lower than that..

Is OCz vendetta 2 good enough? or will ultima 90 do the job?

@ratedsuperstar,
my cores temp differ by 3-4 degrees too.
But there is temp issue in 45nm's, at low temperature, either one or both the cores will stuck at a constant value, even if you are on north pole. Like in my case, cores wont show value lower than 36C, but the IHS value shows 30C. So this means core sensor is stuck at 36C.
