I have no idea what's going on... I just installed this program to monitor the temps. Anyone have any ideas? :confused:

Also... I have an x700pro with ATI Silencer, and idle temp is around 40-43C, according to ATITool. Fan is running 43%. Is that normal? I've read around and most people with high-end cards + Silencer get like 30C idle.

What I usually do is to fire up Prime95 and monitor the one that starts trending upward. And that should be your CPU temp.

Hmmm ... Your HD temp (47C) seems rather high to me ...

Are you sure you have that many temp sensors? those could be just invalid numbers which have no temp sensor so they give fake numbers.

How do I check?

dl the right config version for your MB.

also your MB manual should say where temp sensors are.

for my MB, speedfan records an outrageous temp for mY northbrige, yet after checking a MSI forum I found ppl had similar problem and the Mod told them to ignore temp because there is no temp sensor for Northbridge for my MB. In fact the fake temp was removed from a similar MSI app for overclocking/temp monitoring called Corecenter.


your temp 3 is funny 128 cel. yeah right. i smell smoke :)


here is mine btw

Everest Home Edition is pretty good - it actually tells you what components are at what temperatures. Of course, it might not be accurate (temps vary from program to program), but it'll at least give you a better idea of what that extremely high temp is for. I wouldn't worry - a temp of 128C at idle can't be *anything* serious.

good idea test it with other apps, another is motherboard monitor.
I did not find much info on speed fan as far as a forum for the app, so you may want to check the forum of your motherboard and do a seach for speedfan like i did.You should find ppl with your MB with similar questions and answers.

one of my previous system was screwed up like that too. i always thought it had something to do with the mobo. cuz all the apps would show similar number which made no sense at all.

Yeah my mobo kind of sucks. I'm going to blame it for the screwy temps. Thanks all.

I don't really trust some of those programs. The one to moniter temps that came with my gigabyte mobo once said my cpu was running at 1,500,000c and my fan speed was 26,000 rpm before I downloaded the new version of the program which then corrected this "small" error.

Putting together some PC's to sell, and one of them gives some interesting temps. An Iwill P4HT motherboard with a P4-2400 533fsb northwood. Cpu temp is 15c at idle :-0 with a thin layer of arctic silver and a prescott HSF. Temp is the same in the bios and with Everest. Room temp is 20c.

i use nvidia monitor and it works great for my abit nf7s nf2 board. speedfan gave me crazy numbers and so did mobo monitor.

for my MB, speedfan records an outrageous temp for mY northbrige, yet after checking a MSI forum I found ppl had similar problem and the Mod told them to ignore temp because there is no temp sensor for Northbridge for my MB.Really? I had an MSI K7N2-ILSR and even that had a sensor for the NB - the manual didn't say anything about a sensor on the NB either but there was one. I was for a while wondering what the 3rd sensor was when I was monitoring temperatures because it was so high at 60 degrees. Then one day I noticed inside the case that the NB fan had died and when I touched the heatsink, it was burning hot. I set out to buy a good performing NB replacement and the 3rd previously unknown temperature then dropped to 31. This led me to believe that there is in fact a sensor for Northbridge, but that's just my personal experience, take what you want from it. :)

How about try blowing a house fan directly into your case and if that 3rd temperature drops, then it proves the existence of a 3rd sensor *somewhere*, because it's active. And I'm willing to put my money on the NB. ;)

As a note, pretty much all Motherboard, CPU, GPU, etc. temperature monitors can vary widely in readings, even from the same model to model.

It's common to see +-20 degrees celsius to actual temperatures.

Temperature monitors are only really reliable for measuring temperature changes ie: it went from 30 to 50..

Comparing board to board, especially from different manufacturers is genereally meaningless.

While I do agree that sensors from different boards may vary to an extent, a 20 degree variance in temperatures is pretty out there... in my experience, sensors are pretty close regardless of motherboard - but that's just me... :rolleyes:

Yes really, are you sure you are not confusing temp sensor with the fan speed sensor (which my NB has)? After getting squirly temp numbers (eg 85 cel jumps to 15 cel jumps to 45 cel in 2 seconds) for what i thought was the northbridge, I checked out my MB Neo2LS forum and found (written by the moderator Danny):

http://forum.msi.com.tw/index.php?PHPSESSID=d078c253be2882f990a2d8426bd10e 5b&topic=28332.0

" Speedfan settings for 865/875:

Use the F2 Key to rename as follows:
Winbond W83627HF
Temp1-Rename to "System"
Temp2-Rename to "CPU"
Temp3-Rename to "NB" [However, board has no sensor, so ignore number P4 Neo Unofficial Guide]

Their is no NB temp sensor installed in these boards. Therefore the terminals where it should be wired are picking up stray voltages. The stray voltage gets calculated as a temperature.

Therefore, do not worry about the NB temperatures - they are bogus, meaningless numbers that have nothing to do with temperature.

With SpeedFan, you can control the NB fan with the CPU temperature. This will allow you noise reduction and it stands to reason that the NB won't be working that hard if the CPU isn't. Some members here have used digital temperatures to measure the NB temps at idle and load with and without the NB fan. The fan doesn't do that much - a 2 to 3 degree C change. You can get by with no fan and just use the heat sink. "


Before I knew about the fake temp reading for my MB NB,
I tried my NB with/without fans and 2 different heatsinks this did nothing with lowering the temp reading in speedfan (because there is no sensor on my NB).
THe NB fan is so noisy I took it off and my XP 90 is helping to cool my NB heatsink now.

Temp readings using speedfan, corecenter, mbm5 are only mildly elevated over readings with a real temp probe from radio shack which someone on the msi forum posted for my MB. User posted stock numbers for CPU NB btw.
