hi all need some advice. I've had my E8400 for awhile now and i'm considering overclocking it but after doing some standard checks i was somewhat surprised at its current operating temperature.

Lian Li PC60 Case
Asus P5Q-E
Intel E8400
Arctic Cooling Freezer 7 Pro + AS 5 (running at medium settings on the mobo)
4870 1Gb
OCZ 4GB DDR 2
etc etc etc

As you can see real temp reports

36C min to 59C max at stock speeds (thats after 10 passes of IntelBurnTest 2.0)

my question is Shouldn't a 45nm CPU run alittle cooler than that? Or am in the right ballpark temps wise? Thanks in advance for feedback...

You're probably a little higher than it could be - possibly a lack of airflow through the case due to low speed fans or obstructing cables. The Freezer7Pro is also a little outdated for overclocking these chips.

They're not outlandish though. The main thing to look at is the difference between idle and load, yours being about 20c - that's the indicator of how much headroom you have in the temps. The actual idle and load temperatures can be reduced.

ie bring your idle down to 20 and you can probably bring your load down to about 40, giving you 20c of reasonable headrooom.

I'd look first at upping fan speeds slightly, checking there are no obstructions, moving hard drives and graphics cards to direct airflow better, tidying cables. Reseating the HSF a couple of times to see if you can get any improvement shouldn't do any harm either - it may be that you just have an unlucky uneven spread of thermal paste etc.

Finally look at updating the cooler - the freezer 7 pro is fine for the cost, but if you're serious you should probably plan to spend £30 on a decent cooler.
 
Idle seems a little high, but the load temps (which are more important) are in the ballpark for that cooler using that software in my opinion. Also, I am not 100% sure if realtemp reads Wolfdale CPU temps accurately. I know it certainly doesn't for mine.
 
My e8400 o/c 3.6ghz runs at 30c - 32c idle and 44c 100% load for 20 mins using realtemp...

Coretemp reads 35c idle to 49c load with 20 mins at 100% on both cores.

I have the freezer 7 with fan set to stable in asus tools i think its 30% untill my cpu reaches 60c. Anyway the cpu fan speed reading in speedfan is 1480 rpm.

I dont know if it helps but at least you have something to compare with as my system is cooler than other air cooled pcs around the forums but that could just be my case.

I don't think its a case issue tbh, the internal layout is very tidy (even if i do say so myself ;) ) and the air flow from front to rear is very good which is reflected in the motherboards temp of 35C, strangely enough pc probe 2 reports the cpu idling at 30C (shrug). Even if i run the front case fans at max and the cpu cooler fan at max i cant drop the cpu idle below 36C (core temp reading)? Anyway i'm going to pick up a Titan TTC-NK85TZ Fenrir (on offer this week) and see if that has any desired effect. Although I'm thinking Clairvoyant is correct about bad idle sensor readings on these e8400's. Still a new cooler wont harm it ;)

Thanks to everyone for their input, ill make a further post once Ive installed the new cooler.

Mines doing 3.4ghz E0 step and idles at about 15-25% load at 37deg with a noctua cooler in a NZXT temptest case 6 case fans so i wouldnt worry it doesnt go much higher when clocked to 4.2ghz.
