Confusing temp readouts

Ok here is my problem. I recently did a what I considered very modest overclock to my Core i5 760. It is overclocked it to 3.2ghz and I am getting what you see above for an idle temp. What is confusing me is why the cores show to be perfectly cool and the CPU shows to be 15C higher. It is running a stock cooler, but I don't think it should be idling at 45C with that small of an overclock. Also I even turned on the turbo fan profile and that is with the fan turning 1750RPMs!

One thing I am pondering is I used the Asus auto tune and I noticed it upped the RAM voltage to 1.65v. I know the memory controller is on the CPU, so maybe this is where my problem is?

Edit: Well there goes that theory. I put it on the X.M.P with 1.5v and it is still getting the same temp readings with no overclock. I am beginning to wonder if that CPU reading is just crazy and I just need to pay attention to the Cores. I am kind of new to overclocking, so I am not sure on this.

Check the temps with RealTemp. It's known to be one of, it not the best, at reading the digital temperature senors on the CPU's.

That seems way to hot to me. I don't understand why it is so high at idle though. How hard would it be to get an aftermarket cooler on there like the CM 212? I have a HAF 922. Does that case have a big enough opening behind the motherboard to get that on without pulling it out?
 
CPU sensor is your cpu socket temp sensor. either way realtemps the better one to use on intel processors for cpu temps. use speedfan for system/hard drive temps.

your temps look fine for the stock cooler since you have speedstep disabled. the fan speeds correct as well. it will ramp up as you put load on the processor and the processor temp goes up the fan speed will go up as well.

Even for idle? The CPU is not under load at those temps. It jumps around 80C under load with Intel Burn Test.

Edit: What is confusing me is the "CPU" temp is showing 15-20C higher than any of the Core temps. If you go by the core temps this processor's temps are running right where they should be. At idle the cores show to be about 30C.

Edit: I went ahead and ordered a Cooler Master 212. Even if my temps are acceptable cooler is always better. Besides it will give me a lot more overclocking headroom.

Ignore the CPU temp reading for purposes of overclocking.

The core temps are the cpu in-core temperature sensors, while the CPU temp is typically a motherboard socket sensor.

50C idle and 75C to 85C IBT are normal for the stock intel heatsink when QFAN is on. I have seen these at least 1/2 times on quad core processors. Core2 and above.
 
Well even if it is normal I am temperamental and like my stuff to idle cooler. =p So the 912 is on its' way. Is there any reason why I should not just use the thermal compound it comes with? Also any recommendation on how I should apply it?
 
Looks like i got the same issue with the OP :D My CPU temp is always 10+ degrees higher than cores temp lol.

if you want lower idle temps then turn speedstep on in your bios. with speedstep it should idle right around 38C-40C(using realtemp and not speedfan which is incorrect).

as far as the 212+ you can use the thermal grease that comes with it. there really isnt much difference between what they send you and arctic silver 5. most of them perform about the same + or - 1-2C. not a big enough deal to bother spending the extra money.

Great! Thanks for the advice.
