I tried the program called Core Temp and its showing the Core0, 1 temps 5C LOWER than HW Monitor is showing
Which program should i trust ?
(after a few steady minutes in Orthos its showing me 65-67C MAX and a VID of 1.2125 while HW Monitor is reporting 70-72C) i also lowered the voltage in BIOS to 1.275 and CPUZ is showing 1.216 - 1.232 so far everything is stable as i type this
You say you over-clocked this puppy to just short of 4.0Ghz, but your sig says 3.6.
I also have an E8400, but couldn't get it past 3.8 with a voltage setting somewhat higher than yours. I'm wondering how many hours you are stressing the system to declare "stability." Maybe you're really lucky with what came as a prize in your Cracker-Jack retail-box, though. Or maybe it's just the P35 chipset: My E8400 was set up with an nVidia 680i board which is currently out in "RMA-land." Things have changed, though, because I'm running an E8600 and an nVidia 780i board, and . . . "it's happy, I'm happy."
Now, about the temperatures.
There's a good explanation of Conroe temperature sesnors at Tom's Hardware:
Core 2 Quad and Core 2 Duo Temperature Guide
I tell you to read it, because it provides insight to the basic facts about the TCASE sensor (measuring temp at the IHS-processor-cap) between the cores, and the Tj core temperature sensors -- embedded in each core respectively.
Then take a look at an Anandtech Article on the E8500 processor published in March of this year:
E8500: Best just got better
As good as it gets, this may not explain that many of the Wolfdales have been shipping with sensors that are "seen to be defective" when Intel is suddenly saying "the sensors are not meant to read idle temperature values." So people perceive that they are "stuck." They are "stuck" below a certain nominal value.
At idle, and with on-the-edge-current BIOS update, my E8600 shows 56C/56C at idle. Those are the Tj core temperatures. The TCASE temperature is shown in BIOS, and seems to vary properly between idle and load. When my load temperatures for the cores exceed 56C, the temperatures start to move.
Because your monitored voltage values seem so low, I'm not all that happy with your load temperature values. If you were to run IntelBurnTest, I would guess they would climb to the low 80's Celsius. By itself, this is not a problem, but it is getting close to one.
The thermal spec for the Wolfdale -- the point where the CPU will shut down from over-heating -- is a TCASE value of around 75C. What seriously bother me here is that your show a CPU temperature that only moves between 42C and 43C idle to load, but a system temperature (motherboard) that moves between 32C and 59C. This latter variation seems more characteristic of a CPU TCASE variation idle-to-load, while the former -- for being 5C or so too high -- is acting like the motherboard sensor.
And for the voltages being reported in the monitor, your Tj core temperatures still seem too high (I already said that). So in addition to getting your monitoring software to read and report temperatures with the right labels, I'd try to focus attention on CPU cooling and case-airflow.
The Freezer 7 Pro should do a better job for you than it is.
I'm only over-clocking my E8600 to 4.0Ghz, and my load temperatures under INtelBurnTest, room-ambient around 78F and a Noctua-NH-U12P CPU cooler are peaking at 65C degrees. [Of course, I lapped my IHS and heatsink-base to bare copper and used synthetic-micronized-diamond thermal paste.] But my reported VCORE or CPU voltage is around 1.26V.
If you just didn't make a mistake of massive transpositional dyslexia in telling us your temperatures, see whether there isn't a newer BIOS for that motherboard. There are ALWAYS bugs in BIOS's, and some of the "Cadillac" boards have to go through five or ten BIOS revisions before all the little inconsistencies are cleared up. That's why I usually wait 6 months after a board is released before I bother to buy it.
