id trust bios the most but with 2 readings at 30 its a safe bet its 30c
tried coretemp? that forth reading should confirm it

id believe about 30 then....21 is about room temp so i highly doubt its that low

People say Realtemp is the best, but that reading seems a bit low...
Its pretty cool in my house, no heating on and most of the windows open all day.

The realtemp reading sounds abit optomistic.
Realtemp is where I put my faith these days, for 45nm CPUs at least. Beats my 244 degree reading in BIOS anyway! 
Having said that 21 sounds low. Have you calibrated realtemp?

i have an e8400 in the AI suite it shows 36 idle real temp shows 39 idle so quite close really this is on bog standard cooler with chip running at 3.4 nothing major
ie. you've got RealTemp reading exactly 5 degrees less than CoreTemp, which reads exactly 5 degrees less than OCCT...
That'll be because they will all be using different values for TJMax (temp at which CPU starts to throttle). There's loads of discussion about this in the thread over at XS - problem is Intel basically just don't say what it is so everybody just has to guess.
I still reckon RealTemp is the best of the bunch, particularly for 45nm CPUs. The guy who's made it seems to have done his homework.

Mine is very similar with real temp Vs coer temp.
Real temp says my cores are...
33'c and 34'c,
Whilst core temp says...
43'c and 43'c.
Are we saying that real temp is more accurate?
My motherboard says my temp is 250'c so im taking no notice of that

Is yours watercooled then Althulas?
My temps seem high compared to yours. My cpu is on 3.7ghz and my tunic tower is not far off full wack.

My 8500 is at 3.7 using the Noctua cooler.
Real temp reads 33/34 idle, 50/51 after Orthos test for an hour.
Core temp reads 43/44 idle, 60/61 after Orthos test for an hour.

Seems to be the norm on air i guess.
There you go... CoreTemp using TJMax of 105 degrees, RealTemp using TJMax of 95 degrees.
Basically that means that CoreTemp will always read 10 degrees higher than RealTemp (well, for as long as neither program changes the value of TJMax they use) (Edit: and only for E8400s obviously, since different classes of processors have different TJMaxs)
This is because the programs do not (can not?) measure the temperature directly, instead they measure the distance to TJMax, whose value has to be guessed because Intel don't specify what it is. So if your TJMax is wrong all your temps are going to be off.
The big question is of course, which is right? This is more or less up to the individual to decide who to trust! Having followed the thread over at XS on the development of RealTemp from an early stage, that is the one that I trust.
This is mainly due to the developer's thourgh and scientific approach, use of IR probes, other members contributions etc. I would advise everyone to read through the thread and make their own mind up.

No just using Artic Silver5 kit, Zalman CNPS9700 and Antec 900 casewith all cables tidyed away so have got good flow through my case.

well my E8400 is insane and I dont know which temp to trust:
BIOS: 15c
SpeedFan: 15c (core 1: 55, core2: 52)
CoreTemp: core1: 57, core2: 53
RealTemp: Core1: 42, Core2: 45
Everest: 15c (core 1: 58, core 2: 51)
I live in Nicaragua (very hot country) so my room temp is about 32 to 35c so 15c sound really unrealistict.... My "Fingernometer" say that the Stock heatsink its not that hot, so I guess my temps are the one in Real Temp.
Im waiting a Zalman 7500 to arrive (that about the biggest cooler that can fit in my Lanbox case) I will report any change in temps....
