Seems like Everest home edition doesn't recognize core 2 cpu's. Anyone suggest another free program?

Thanks!
 
For now, CoreTemp 0.95 is the most accurate, along with TAT. SpeedFan 4.32 is good but not on all models of CPU.
 
With a E4300 you need to make sure you get the 0.95 version of Coretemp - the 0.94 reported incorrect temps. And my vote is for Coretemp.
 
It's funny, at default voltages, TAT reported slightly higher temps than Speedfan, but when I bumped all the voltages, the TAT now reports lower temps than speedfan.. Oh, another things - at stock voltages, AUX in speedfan showed some insane temps - 75c to 125 c, but with higher voltages on FSB, MCH etc, the temp reported are like 30-40c... go figure with these things :D
 
I'm in agreement with the other experts here that CoreTemp v.0.95 is the most accurate temperature reporting tool presently available for the Core2Duo.

It seems to work 100% for the E4300 as well as the Revision B2 E6x00 series. I've heard one rumor that it may need an adjustment for the new Revision L2 E6300 / E6400 but I can't confirm that. Version 0.94 is also still available from his website.

Try either one individually but don't try running both versions together at the same time. Trust me on that! :D

I'm not so sure if this version of coretemp (0.95)is accurately reporting these temps (at least on my rig- check the sig). I dropped my clock down to stock and with the Ninja heatsink (ambient room temp is like 65C) I'm idling at 43C according to core temp. And it seems impossible for that to be right. Hopefully they figure something out and I just don't have a ridiculously hot e4300. Speedfan seems to agree with 0.94 temp wise, and TAT won't run on my rig so I'm stuck with the combination of those two. Before this new version coretemp is definitely my vote for the best temp monitoring program out.

My lapped E4300 at 3.3 idles at about 40C with a lapped Ultra-120 and 1200 rpm S-Flex, so I'd say that 43C is is not impossible. I've got a 1600rpm fan on order so we'll see if that helps any. Oh, I just saw that that 43C is stock - that does seem high, was that stock volts as well?

And you're lapped e4300 at 3.3 idles at a lower temp then my stock speed idles at. I mean come on, there must be something wrong here.

I'd check your HSF contact - my temps were really high so I put on just a thin coat of AS5 and checked the contact and found out that the HSF was only touching about half the processor because it was so concave. After lapping I get much better contact - temps are still high, but I have less than optimal caseflow so I'm not too worried about it.
 
Moe.RON: 43C is a normal idle temp for a Core2Duo.

CoreTemp 0.94 was proven wrong on an E4300 because it was reporting idle temperatures below ambient on some users air cooled systems which was impossible.

I've been doing my own research lately and this whole damn temperature reporting problem is 100% Intel's fault for not properly documenting how to find out in software whether a chip has a maximum temp of 85C or 100C. Knowing that info is crucial for calculating the temperature of a C2D processor. Unfortunately Intel is not interested in sharing this information to individual software developers like the person who wrote CoreTemp.

If you want to read what it's like dealing with Intel about this issue then read this:
http://softwarecommunity.intel.com/isn/Community/en-US/forums/1/30229027/ShowThread.aspx

It was originally believed that all C2D processors had a max temp of 85C but the E4300 max was discovered to be 100C. That is why CoreTemp 0.95 should read 15C higher than the previous version with your processor. You may not like the bigger number but it is definitely right for your E4300.
 
Here's one safe way I discovered to test whether a temperature monitoring program is reporting the correct temperature.

Lock your CPU multiplier to the minimum value of 6 and reduce the MHz to a default of 200 MHz for the E4300 or 266 MHz for the rest of the C2D processors. Set core voltage down to 1.20 volts. Open up your case and make sure your CPU fan is at its max. The goal is to get your idle temps as low as they'll possibly go.

Boot up your computer and check your idle temps now. Once your computer stabilizes, you should be able to get core temps close to ambient if your cpu cooler is working well.

If CoreTemp 0.94 reports temperatures that are below ambient then that proves that it is wrong. If it is wrong then CoreTemp 0.95 has to be right.

The program is simply reading the value of a register in the C2D which indicates degrees from maximum. When this value hits zero then your processor is at its maximum temperature. If it reads 70 then your C2D is either running at:

30C ( 100 - 70 ) if it's maximum design temp is 100C ( E4300 )
15C ( 85 - 70 ) if it's max temp is 85C like most C2D processors.
 
Are the 2 core temps on Speedfan the same as Coretemp? Ive never really cared too much about temps but from what Ive seen, it looks like the cpu temp ( not core1 and 0 ) in speedfan is consistent with the hardware monitor in the bios....... TAT at idle is just all over the place, jumps up and down probably 6c lol.......

When the computer is at full load, I use both TAT and Speedfan and go with whichever temp is higher.....

Nice.

When my ambient temp is 65*F, I idle at pretty close to that, depending on which program you believe.... (18.4*C = 65*F)

CoreTemp 0.94 and SpeedFan 4.32 report exactly the same core temperatures.

After their release a bug was discovered. Tmax for the E4300 is really 100C and not 85C like all of the other C2D processors. This bug was corrected in CoreTemp 0.95 so that it is now your best bet for accurately monitoring core temperatures.

On the older processors there should be no difference but on the E4300, CoreTemp 0.95 will report a number 15C higher which is the correct temperature to be reporting.

The bios temperature is a meaningless number. The only important number to watch is core temperature reported directly from the digital probe within the C2D core.
 
I did some testing last night and my conclusion is that NO temp monitor is accurate ..... My watercooling is very good i think but it cant be this good lol..... water temp at the time is 8.5c ( taken from reseviour ) before it goes through my radiator which is outside the house ( along with my 8 gal res )...... you be the judge Unclewebb..... these cant be right even if if only using stock vcore, can it?......


At idle....

From what I understand the max temp is 100C. Does this mean that I can run it at higher temperatures and not do any damage to it? Usually I try and keep them below 60C, but if its got a higher tolerance for the heat can I run it hotter without any detrimental effect on the life of the processor?

Up to 70c-72c is pretty safe, they will run up to 85c before throttling, but you really want to stay away from 80c. You need some headroom for temps, especially if you are overclocking (is there any other way???):p

The higher you overclock, the more attention you need to pay to temps. Stock speeds, bah, 75c would run all day and night, at 1ghz+ overclocks, temps become more critical and instabilities can occur at a lower temp than they would on a stock cpu.
