Thermal Shutdown Function

[SilverJock]

Hi All

I have built this new pc and put an Athlon 2400 in with a gigabyte board, i am getting a random shutdown now and again (not a restart). It also gives a short alarm( sounds like the old nee naw police cars)just before it shuts. I notice in the manual that one of it's features is a Thermal Shutdown Function, but i can't find any further mention of it.
Can anybody give me some more info on this?

I asked the shop to make sure that the fan i got was adequate for the 2400, it is a fair size but maybe somebody could advise. I have looked in the bios and it is running @ 89c. Is that Ok?

Thanks for any help

Steve

89c is way high! Make sure you have the heatsink on the right way 'round as it makes a big difference. Also male sure you took off the paper over the heatsink pad or paste (you do have some sort of heatsink compound in the heatsink don't you?)

Try this:

1) Update the bios

2) Do you have a good household fan? If so, remove the side of the PC and set the fan up to blow air into it at the highest speed, then use your PC for a few days and see what the temp goes to.

If your temp stays low this way you have a cooling problem and need to get better / more fans in your box...

Don't drink and post, save that for driving home!

The fan is on the correct way, and there is heatsink on it although just the stuff that comes with it already.
Do you think i need to put some more on?
Can you tell me what temp it should run at?

Thanks

No, don't put more on unless you get the good stuff and then clean off all the old. Too much is not a good thing. I would say you want to shoot for the mid 50 - 60 range.

Typically idling in the low 50's C with maximums in the mid 50's C
89C is way too high!!!
You may think you have fitted the heatsink the correct way around and to all intence and purposes you cannot see any differance but I assure you these temps indicate that the heatsink is not properly touching the the CPU in some way!!
The recess in the base of the heatsink must be fitted so it is mounted over the raised part "socket A" writing on the CPU socket.
Just a small amount of thermal paste (1-2 rice grains in volume) needs applying to the small raised rectangular CORE only, not all over the CPU's top surface.
If you have used the pink thermal pad that comes attached to some heatsinks you must remove the protective plastic tape!
Don't take correct fitment for granted, remove the heatsink and double check.

Replying helps further our knowledge, without comment leaves us wondering.

I have taken the fan off and it as it should be, the fan is fitted correctly and the paper is off the heatsink. The cpu core is sitting in the middle of the paste just at the copper core of the fan. I don't see any brand on the fan, although it is 3 inches deep and looks like it should be ok.
I should maybe buy a volcano, what do you think?

Thanks

> 89c. Is that Ok?

NO! I'm surprised your BIOS hasn't closed down your PC - any higher and there will be damage.

I would say that with good cooling the temp at idle should be below 45°C and not rise above 60° in extreme conditions.

89 degrees is actually 4 degrees over AMD's specified maximum die temperature for an XP 2400+. Obviously there is something wrong with the heatsink or its installation, or perhaps a bad heat sensor, though I wouldn't know how to determine that.

A good site for grease installation is here:

Is the heatsink oriented properly? The recessed portion of the bottom of the heatsink should be over, but not on, the raised portion of the CPU socket.

Thanks for the help guys, i put a volcano in it and it now runs at 50c, and it has stopped crashing (strangely enough)
The fan i had was obviously crap but all seems ok now

Cheers

I would still consider better a cooling system. I have a AMD2200 that runs at 32c. This is with a Volcano 9. My biggest temp drop came when I put a side fan on my case, blowing ON the CPU. Some cases come with the side fan blowing out. Since the Volcano fan blows down on the chip, this created a "dead" spot above the CPU when blowing out.

AMD does run hotter than Intel. I have enclosed a brief article from AMD's FAQ. I also included the web site. Your processor seems to be within the range prescribed by AMD.

1.3 What is the maximum operating temperature for my AMD processor?
The maximum operating temperature of an AMD processor is determined by the processor's
Ordering Part Number (OPN). The OPN is located on the top of the processor.
Example: A X1800 D M S 3 C
The temperature is indicated by the third character from the right in the OPN and is denoted by
an S, T or V character. Current data for the AMD AthlonTM XP processor identifies the maximum
operating temperature as: V=85ºC, T= 90ºC, S = 95ºC.

Of course the cooler you can keep you CPU the better.

I hope this helps you.

p.s. You are right at the top end of the MAX. Get a better cooling system.
