surprise!! core 2 duo e4400 no oc temperature

lucky you... those are good temps

jhyukkang, 77F = 25c, so as you suspect, the Cores should not Idle near 25c when ambient room temp is about 25c, regardless of BIOS settings. Remember there are 2 separate temperatures for C2D's;

• CPU temp - Idles slightly higher than ambient.
• Core temp - Hottest Core Idles 10 to 15c above CPU temp, depending upon Stepping.

Stepping determines temperature specs.

• Is your E4400 L2 Stepping or M0 Stepping?
• Are you using SpeedFan 4.32 or 4.33 to monitor temps?

If you're using SpeedFan, then Core temps indicate 15c too low, and simply require "Offsets" to indicate correctly. It is now possible to "Calibrate" your processor temperatures. If you'd like more detailed information on temperatures, check out the Core 2 Quad and Duo Temperature Guide: http://www.tomshardware.com/forum/ [...] ture-guide

i use speed fan 4.33 and i also went into bios and have checked it
core 1 is usually 27, core 2 is usually 25C
and i have old laptop from 6 years ago
i bought that laptop for 3000$ 6years ago.
it has p4 with 1.8g, 512ram, 40gb hdd, geforce 4
at the idle that p4 runs at 58C !!!!!
like in every 7minute, cpu fan runs highest speed and kinda loud

jhyukkang, if you'd like me to help you sort this out, then I need complete information. Please re-test and fill in the following items - follow the Guide if you're not sure what to do:

CPU = Idle & Load ???
Hottest Core = Idle & Load ???

Ambient = 25c ???
Chipset = ???
C2Q / C2D = E4400
CPU Cooler = ???
Frequency = Stock @ 2.0 Ghz
Load = Prime95 Small FFT's - 10 Minutes
Motherboard = ???
Stepping = ???
Vcore = ???

Evilonigiri, SpeedFan is still the temperature monitoring utility of choice, specifically because it is flexible and configurable, regardless of whether or not it requires Offset corrections for certain Cores. It is never my intention to imply or suggest that Core Temp should be preferred over SpeedFan to monitor temperatures, but I do recommend that Core Temp, CPU-Z and Crystal CPUID be used to cross-check SpeedFan during Calibrations. There are good reasons for this, which are all clearly explained in the Guide.

Ilander, the +15c Core Offset correction issue for SpeedFan is not confined to Quads only. The +15c Offset correction applies to C2Q's and C2D's which have Core Steppings that specify Tjuntion Max 100c. It is therefore inappropriate to also add a +15c Offset correction to the CPU temp. CPU temperature as well as Core temperatures can be accurately Calibrated using Section 9 in the Guide.

SpeedFan Beta 4.34 resolves the +15c Offset correction issue, however to download it, users are required to jump through several hoops, which some may find too cumbersome with which to bother. This is why I haven't yet recommended SpeedFan Beta 4.34 in the Guide. When 4.34 is officially released, I will update the Guide at that time to include it. I am currently using Beta 4.34, and my CPU and Cores all Calibrate to zero Offsets.
