Good program to monitor temps?

[Rising]

Is there a good program that can monitor the temps in my comp? At the very least, the CPU. I'm running Vista Home Premium SP1 x64.

if you built your own computer, there may be a monitoring application on the motherboard disc. as far as freely downloadable programs, try either (or both) speedfan or coretemp.

SIW is another option,

SIW | System Information for Windows by Gabriel Topala

It will show readings for just about anything that has a sensor.

Another vote for Speedfan or Core Temp, though Speedfan will also read your hard drive's temp as well.

I use Everest (Pay Program) it is also a very good program that reads all sensors and system info.

Same here. A great program that provides a wealth of information. However since he specifically asked for temperature reading programs and Everest is much much more than that and costs $35.00 dollars (US) I didn't think to mention it.

There's alway the trial version though - Lavalys - Comprehensive IT Security and Management

P.S. just noticed the 5.0 release which I’m eligible for

Which one should I trust...

OK, checking my CPU temps with the 3 programs reveals 3 different sets of temperature reading. So which one is more accurate???

First my CPU info as read by CPU-Z



Now Core Temp temperature readings... (32, 32, 28, 28)



Next, Everest Temperature Readings... (37, 37, 33, 34)



Last, SpeedFans's Temperature readings... (47, 47, 43, 43)



So which program would you trust??? All programs "supposedly" has Vista 64 bit support.

Good question,

Normally they would give the same readings as they read from the same places

Have you done all three measurements at the same time?
Could this be a conflict ?

My Everest temperature for the CPU matches the Bios

I know that you can adjust the Speed fan temperatures if they are not showing right

No I haven't done all three at the same time; they were done in succession, one after another.

However, I think I know what's going on, and it has to do with the Temperature Junction setting used for a given CPU by the temperature reading software.

Temperature Junction or Tj. Max is the maximum theoretical temperature a core can reach before shutdown. As we can see by these programs, there are various opinions as to the max T-Junction of a B3 Q6600.

Now… let's use Core Temp as a baseline with TJ Max of 85 degrees for a B3 Q6600.

Now if you compare Everest's TJ Max reading of 90 degrees and look at its temp readings of my Q6600, you’ll notice they are 5 degrees higher than Core Temp’s, which also corresponds to the 5 degree difference in the TJ Max readings. 85 for Core Temp, 90 For Everest.

Now, again, using Core Temp as a baseline and comparing SpeedFan's readings, (here's where a little guesswork comes in, as I don't see a TJ Max reading in SpeedFan) we can see the temps are 15 degrees higher than Core Temp's reading. Using the TJ Max delta logic, I can surmise that the TJ Max used in SpeedFan is probably 100 Degrees.

So…using the TJ Max readings you can see that the temp readings are the same across the board.

Core Temp (Tj Max 85) – Temp reading 32, 32, 28, 28
Everest (Tj Max 90) – Temp reading 37, 37, 33, 34
SpeedFan (Tj Max 100?) – Temp reading 47, 47, 43, 43

Incidentally Core Temp and Real Temp use the same Tj Max settings and give identical temp readings.

So…which one is accurate…to find that answer we need to know what the “true” t-max reading of a B3 Q6600 is (something I guess Intel is keeping secret about?).

However, Intel does list the Thermal Design Power of a B3 Q6600 as 105 Degrees and the Thermal Specification as 62.2 degrees, but these are not the same as Temperature Junction.

Here’s a good article at Toms Hardware on temperature readings on quad core CPU’s - Core 2 Quad and Duo Temperature Guide

Ok I'll take your word on this. Nice explanation by the way. Have you used all the latest versions as I would like to try it on my compy and see what results I get with an AMD

Pooch

 

[sygnus21]

Yes, I checked. In fact if you look at the links to the software, you'll see they're the latest versions, including Everest which I just updated today.

I have locked my processor at low speed to keep temps constant.
Core Temp refuses to run not really surprised about this
Everything is a lot more stable

Do you know what tj max Everest is using? Also will Real Temp run on your machine?

What you want to see is if your CPU shows different Tj max readings between the different temp reading programs, and not necessarily the temp reading themselves.

Again for me, Core Temp uses a tj Max of 85, Everest 90, and SpeedFan 100, which is why I get varying temp readings between the programs.

Where do I find this tj max for everest?

 

[pooch]

No Real Temp locks my system up tighter than Core Temp
Did try SIW though it agrees with the rest
Everest tj Max is set to Auto If you go to options Hardware Monitoring you can Change the Everest tj max this might be of use to you

Wow lots of info here. Thanks for the help. I've been using SIW and I hope that's accurate. I just built this computer (my first build) and the temps with an i7 920 read:

Value:

42
37
40
33
