Speedfan, Core Temp, Mobo Temp all different

post #1 of 14
Thread Starter 
I know that they supposedly all use different formulas to get the temperature reading from the same sensors, but damn, the temperatures are so different. Speedfan and the motherboard monitoring that came with the mobo both read the core 0/core 1 tempeartures at arouns 25-28 idle, while coretemp .95 reads it at 39-43
load the cores go 40-45 and 58-65 on coretemp.
I really don't know which one to follow...I have a very good air cooler ( TR 120 extreme - mounted properly) and pretty decent case ventilation, and I just can't see my cores being at 40 or so degrees @ idle, especially when they are throttled down. My V core isn't excessive either, in windows it's@ 1.39....
at stock speeds I still found coretemp in the high 30s@idle.
Using Vista 64.

I just don't know, those numbers just confuse me sometimes, maybe I'll just unistall coretemp lol

what are ambient case temps? I stopped trusting Speedfan like everyone told me because my core1 and core2 temps read lower than case ambient temperature by a couple degrees.

don't uninstall Coretemp until you are sure that your temps are right. Like I said, when idling at 25 C, what is the ambient case temperature?

I wish I could tell you... that seems pretty crazy that Speedfan and Coretemp are THAT much different. I don't use Coretemp myself so I don't know exactly. Did you use AS5 for the TR 120 Ex?

Nice OC by the way.

I would use Speedfan or TAT. there has been some fuss about speedfan not reading correctly, but the latest version fixed it completely, it now reads the same as TAT.

So if you don't have TAT yet, download it and see wich is right. It was developed specially for C2D's and Meroms, so it should allways display the right temp.

Hope this helps

I can't use TAT under Vista 64 unfortunately

and my Speedfan shows a few temp readouts:
Temp1:37 (never moves really)
Temp2: 27
Core0: 25
Core:1: 29

Coretemp reads the internal core temperature which is usually +- 10 degrees higher, mine tops out on 52c @ 26c 1.575v ambient = approx 42c cputemp....

Which version of Speedfan do you have? the latest is 4.32 and works fine for me..

Temps do seem a bit low though, I'm now running at 2.8 (summer oc, clocked down from 3.2) and temps are still about 44C idle and 57C full load.
Even at stock temps don't seem to change that much, and I have a Zalman 9500.. wich I really have to clean sometime

But normally the temps would be around 40 idle and 50-54 load @ 3.2

I'm curious (because I have the same CPU and running Speedfan 4.32 also).... when you say your temps are 44C idle and 57C load or 40C idle and 50-54C load, are you talking about the "CPU" temp or the "Core 0 / Core 1" temps?

If you are using coretemp 0.95, it is known to act slightly oddly and possibly buggy.

Use 0.94 and see if that is different.

I also found this on the website:

Core Temp works on Windows 2000, XP and 2003 (both 32bit and 64bit versions).
So it may report different temperatures because of Vista.. unsure though.
