Core 2 duo temps

[Raence]

I just put together a new computer with a thermaltake armor case with side fan, a p5b deluxe motherboard with an e6600 and a tuniq tower. The motherboard temps are around 23 idle but the processor is reading 47-51. Probably messed up the mount of the tuniq tower more than likely?

Quite possible, however, there may be other issues. If you would like to see more information regarding temperatures, check out the following topic:

I've been readin that over and over all day. I haven't got the computer hooked up yet to the internet. I'm just noticing the speeds in the bios which are a little unsettling. I popped in the pc probe disk just to see and it reads it around 36 or so at idle.

pc probe...reads around 36 or so at idle.

Load = 51c
Idle = 36c

Please define your 4 variables:

Frequency =
Vcore =
Load =
Ambient =

Thanks. 8)

Everything is still at stock. I just finished putting it together and checked the bios. I know it might not be as precise as tat. Quickly installed windows xp on it and just installed pc probe. Trying to do that in between college work. Thanks for the help CompuTronix.

freq:2.4
vcore:1.288
load: very little, just have it sitting there doing nothing. Haven't done stress test yet.
By ambient I guess your meaning room temp? It's around 73 farenheit.

 

[CompuTronix]

Thanks for the info. After you run TAT/Core Temp/Probe for Tj & Tc temperature benchmarks, you'll have a better idea of your rig's thermal behavior. 8)

 

[Raence]

So basically don't worry till I run all those test?

 

[CompuTronix]

You should be OK for now at stock clock and Vcore. 8)

core 0 runs at around 35-38 sitting idle and core 1 sits at 29-31 running tat. When I put them at 60% load yesterday while partioning a 600gb partition core 0 went to about 58 and core 1 went to 52.

I think I'll have to try and reseat my heatsink I turned it from it's highest to lowest settings and it only changed it a degree or to. Hopefully the tuniq tower won't give me problems when I reattach it.

 

[CompuTronix]

Let me know how it goes with reseating your Tuniq Tower and running your thermal benchmarks. That'll tell us where your temps are at, and how strong your rig's thermal performance is. 8)

Getting the cleaner tonight to do that but noticed that the speed has dropped to core 0 as 34 and core 1 as 27. Any reason for a large difference in the two? Trying to learn a bit also and just kinda curious.

You might have an application that is only using the core 0 and thats why that is running hotter or the heatsink is not properly set so one of of the chip is not being properly cooled. I also noticed something like this when i run dvdshrink, because it will heatup my core0 and not core1 also.

 

[Raence]

Well after reseating everything seems to have gone the right way for me. It is still a bit wierd that each core is about 4-6 degrees apart. Core 0 at idle reads at 26c and core 1 at 19-21. Under full load using tat core 0 goes to 44 and core 1 goes to 40. Only thing left to figure out is why there is no temp difference with the tower fan running at min/max rpm.

 

[CompuTronix]

Glad to see that you're getting it worked out. Remember to use "Core Temp" with TAT for the most accurate temp results. 8)

 

[Raence]

Core temp basically shows the same, I just don't get why it is a 5 degree difference like that. Is it because each core is slightly different due to the manufacturing process? Also pondering swtiching the tuniq, the fan not seeming to do anything is driving me nuts. Time to go see if I mounted it right.

Thanks again for all the reassurance/help. Any other opinions will be appeciated.

 

[CompuTronix]

Don't be concerned about idle temps. How close are your temps under Core Temp at 100% TAT?

 

[Raence]

100% load on both under tat:
46-42 core temp
45-43 tat

With the tuniq tower min they stay the same. With the tower at max it stays the same just the core 1 might dip for a second. Even tried taking off the side panel and no real change.

 

[CompuTronix]

Raence, sorry I haven't gotten back to you till now. Just reviewing your posts...

...just installed pc probe.

What are the idle and load temps in probe?

tuniq tower
freq:2.4
vcore:1.288
load: TAT 100%
ambient: 23c.

idle:
Core 0 at 26c / core 1 at 21.

load:
46-42 core temp
45-43 tat

You see the problem. Obviously it's not possible for the cores (Tjunction), which run 15c above the CPU case (Tcase), to idle below ambient, so you have an offset. The 965's are notorious for this, so we need more info. As noted above, what are the idle and load temps in probe?

Okay just sat with a thermometer to get room temp it is around 22c.
vcore is 1.14

idle temps:
tat: core 0: 28c core 1: 20c
core temp: core 0: 25c core 1: 25c
pc probe: 26c for cpu 29 more mb.

tat 100% load:
tat: core 0: 44c core 1: 40c
core temp: core 0: 45 core 1: 42
pc probe: 44 cpu 30 mb.

The tuniq still doesn't have a difference at 1000 and 2000. Thinking it might just be the case. Still are those temps bad running at stock? Also what exactly is wrong with the 965 chipset? They just have a problem displaying temps correctly?

Probe is correct, but Core Temp (disregard TAT temps) is offset by - 15c. If you factor that value into Core Temp, then you're at 60/57 (Tjunctions), which is ~ 15c above Probe at 44c (Tcase), just as it should be. Don't be concerned about the 3c deviation between your cores, as my E6600 cores are ~ 2c.

Yes, the 965's are frequently reported to have offsets either on Tcase, Tjunction, and occasionally both. This can sometimes be corrected with a BIOS flash and driver update.

At 44c Probe, 60c/57c Core Temp, it all makes sense. These are excellent temps. Just make note of the Core Temp offset, and you're done.

Hope this helps, and enjoy your rig!

I don't mean to be rude but I'm not sure I completely understand that. Would you mind explaining what a tjunction is? Also I take it that you mean my cores are running 15 degrees hotter than what coretemp is stating?

Just checking because I'm looking at overclocking down the road, it is a still awhile away but better to learn now than later. Esspecially when someone is being helpful and is knowledgable. I appreciate it, thanks.
