Conroe proper core temps

Monstermunch · 29 Sep 2006 at 10:59

For those who don't know.....

Intel's TAT is supposed to be the most accurate for reading core temps:

is it normal to have core1 2 degrees higher than core0

Jimbo · 29 Sep 2006 at 13:33

Says both cores are at 50c idle. I wish i could get them down but they are overclocked to 3ghz.

50 idle! My E6600 is overclocked to 3.2Ghz at idles at 36ish, and load is 50-52, on the intel sotck cooler¬! Thats temp reading from asus probe and speedfan. Why is mine so much lower?!

I think you'll find Asus Probe, and Speedfan, read the processors TCase using a sensor on the motherboard.

TAT, and CoreTemp use the thermal diodes located within each of the Core 2 Duo's processor cores. So TAT/CoreTemp are often 10-15 degrees higher.

Interestingly, my own motherboard (Intel BadAxe) seems to report the temperature of Core0. But TAT/CoreTemp are still nice, as they show the temps of both cores separately.

I get this error

"Error enumerating on demand clock modulation support

Terminating tool"

Read the original post.... DL Intels TAT as mentioned above....

My temp idles at 34deg in bios, but is 44deg in TAT which is taken directly from the core. My temps then rise to 57deg under 100% load....

The temp readings from TAT are supposed to be 100% accurate.

There is so much confusion caused by these temp readers its untrue.

Pc Probe reads my temps at 35c idle.

Intel TAT reads both cores idle at 50c and full is 65c

Everest is 35/8c and both cores at 50c idle.

Speedfan reads about 38c idle

I was referring to TATs readings.

Another one with circa. 48-50 idle in TAT......same reading as trusty old CoreTemp gives me.....Everest reports around 37-38 at same time - all these are idle temps

So, with these disaprities in mind, what sort of temps are 'too hot' in TAT/CoreTemp under load ? My setup tends to be hampered by poor in-case cooling, what with the 2 X1900XTs warming the planet :eek:

I had always figured about 50 was a safe~ish temp to be aiming at under load, but TAT/CoreTemp are giving me that just sitting there ! To be fair, they only tend to go up to mid 50s when under load..... (sat under a Scythe Ninja Plus with fan attached)

Shadowness · 29 Sep 2006 at 17:30

So which of the following temps below should I be focusing on?:

AmaTeX · 29 Sep 2006 at 17:46

From TAT i get 38 core 1 and 35 core 2 idle, everest reads 34 and 35 and at load for about 5 mins TAT reads 53 and 50, everest 50 and 53. My room temp is about 20 and case is 21-24. the E6400 is under a BT all at stock, not had time to play

wellibob · 29 Sep 2006 at 17:47

(DS3 User) Speedfan gives me the same reading as easytune & bois readings for the cpu core temps. Thermal analysis tool scared me with it temps readings..lol

Likewise......used to hitting 50 under heavy load only, in OC'ing..... :eek:

I guess for me, as a P5W-DH chappie, temps are pretty OK considering what's in my case and the lack of decent ariflow at present - I have a couple of exhaust fans only, no intake yet

, and the mobo/gfx heat combination is not helped by the tower sitting on a plinth in the corner with nowhere for the air to escape to when it finally does get out of the case :eek:

anyone?

Temps reported by TAT in the 45 to 65 range are normal, it's the temp that the chips are designed to work at.

What makes all us enthusiasts think that our chips should be running much cooler than that anyway? Unless we all got special 'enthusiast' versions that run cooler than joe publics?

If it's in spec, why worry about it?

For the record mine is 40, going up to 52 under load for a couple of hours. Having said that, comparing your own temps to others is useless as every setup is different and you can just end up chasing your tail. They are only useful in relation to your own system, nobody elses!

The only temps I trust with these new chips are those reported by Coretemp and/or TAT, with Coretemp reporting slightly higher than TAT. Or, get an old fashioned temp probe, but even then you won't be able to read the core of the CPU, the hottest bit obviously!

GinG · 2 Oct 2006 at 18:35

according to TAT, wy 6300 clocked to 3.15ghz i 39 idle and only 47 / 48 100% load

kevpuk · 5 Oct 2006 at 00:24

Well, I got me a couple of Akasa Amber 12cm fans (for intake) and a pretty little tube of AS5 and a 4cm Akasa chipset fan en route.....planning a strip down/clean-up/AS5 application/intake fan adding session......should sort out my temps

Mine seems to be exactly the same
