Is this normal ?

[SNAAAKE]

Okay this is been creeping be out lately.

See I have a 800mhz computer that runs(the cpu) at around 30.c

While the 1.3ghz computer in my cabinet runs over 58.c all the time..even when I just start the computer.

Is this normal
I mean I did burn CPUs before and dont want wanna burn this one like that.Its a retail box cpu so fan isnt the issue.
The fan is AMD brand that came with the cpu.

Anyone has anything for me on this?

thanks in advance for any input .

Are both CPU's AMD's?

[SNAAAKE]

yeah..sorry I didnt say it.

Both Duron.

800mhz and 1.3 ghz.

so...?

Ummm, faster CPU's run hotter its not necessarily bad and just because the fan came with it doesn't mean its good. Did you use a good thermal grease between the heatsink and the cpu? Look up the specs on AMD's site and see if they have a recomended operating temp for it.

I just got a Intel P4 2.4G with the manufacturers fan and it ran a bit hot too for comfort so I added a case fan and the chip temp dropped 10 C/18F degrees.  It was running around 47C/116F and now runs below 39 C/102F.  On AMD chips there is probably a chance of even greater heat buildup as they seem to run quite a bit hotter. The faster the CPU the hotter they run.

The additional case fan helps lower the ambient temp in the case and allows the cpu fan to do its job alot easier. If you can put up with the noise add another fan or two.

58 sounds very high.  Are you able to check the temps in the bios when you first start the pc.  I have found that some temperature reporting programs give higher temps than the bios.  Also some try to give the core temp of the chip by getting the outside and adding so many degrees.  I would say the the chip surface is probably about 45 and the program is saying the core is 58.  What prog are you using for the temps?

I am checking From bios.
Nothing is actually wrong with the computer though..except I am little worried thats all..play games perfectly..
Should I just change the cpu fan or get a new case so I could add a case fan?

Which would help?Change the whole case all together or just get a new cpu fan.Isnt the AMD brand fans supposed to be good enough?

Anyone got any link to some *COOL* fan that will cool everything down a little..?

AMD cpu's are known to run quite hot, if you aren't overclocking, a stock fan should be ok, but if you want a little extra, check the site above.  

Also, are you using any thermal grease between the CPU and the fan, that will help quite a bit as well.

I always knew that thermal grease doesnt help much..I will probley just order a good fan or something..VERY good one..thanks for the link..checking out now.

That's pretty high, but not too bad.  IIRC AMD cpus are rated up to 80 degress C, and you're well under that.  As long as you aren't having any stability issues don't worry about it.  Those on-board temp sensors are notoriously inaccurate.

UPTO 80 degrees?
Okay screw ordering another fan..mines well under that..thanks for the response.

Thermal paste is very important to ensure good thermal conductivity between the cpu die and heatsink.  Arctic Silver III is very good at conduction.  You might find benefit in removing the existing heatsink, cleaning the underside and also the cpu die, apply a very thin layer on the die with a razor blade or the like, putting some on the heatsink (can just use fingers but very thin layer) and then place the heatsink back on the cpu.  I did this with my old duron 800 and found the temperature drop around 5 deg under most conditions.

Does you cabinet have good ventilation?  Are you able to remove the pc case from the cab and test it?

Cheers

The heatsink itself is as important as the thermal paste. Cheap (ie. factory) heatsinks could do with lapping as well. If you DO go to the trouble of removing it to clean then lap it as well. If you really want to improve cooling, get a highend fan and heatsink. It'll work wonders.

The fan on my videocard died. I remember touching it a few times while it was running before it died. It wasn't even warm. The new fan has a copper heatsink and a chrome cover and I can't hardly touch it now it's so hot!! It's dissapating heat! LOTS of it! The factory fan didn't do crap.

[SNAAAKE]

well the 800mhz is no problem(running around 30 or so).

I will try to clean and add some thermal paste...

Maybe after couple of rounds of super street fighter.. (MAN !..i am so lazy about everything )

[Nailz]

Just make sure you add a nice, thin even, layer, a little goes a long way with that stuff.

Oh yeah, they're rated ridiculously high.  Seems wrong, at first, but they work great.  My PII 400 regularily operates at ~35 Celcius.

What does "lapping" mean (in regard to heatsinks)?

Is there a good opensource program to report the temperatures of Athlon chips on Shuttle MB?

I think I'm going to install some duct work to my computer before the summer. It gets up to

Thanks.

[teacup]

I have an AMD 1.2ghz which runs at 60 degrees, I thought this was way too high. I did some checking and apparently there are some amd chipsets that will report the temp as double what it actually is. You'll have to do some checking to see if yours is one of these.

lapping is lightly sanding in order to make the surface as smooth/level as possible.  Any imperfections in the heat sink (or the metal plate on top of intel chips) means that parts of the heatsink won't be touching the chip and vice versa... so true l33t overclockers (and other people concerned about heat dissiapation on their cpu's/etc) lapp their heatsinks/etc in order to make the best surface to surface contact for optimal thermal transferrence...

If its not done correctly you can actually make it worse. It shouldn't be necessary unless your trying to get crazy with your CPU.

[toilet]

The cores did change from your 800 MHz (spitfire) to 1.3 (morgan) and the electric requirements are higher. I believe 1.6V to 1.75V along with 5W more of power to dissipate. Although 58C is high, I don't think it's anything to worry about. My duron runs around 54 with a stock AMD HSF.

Lapping involves sanding / buffing down the top of the cpu core to get a more level, smoother, and closer contact with the heatsink. Same with the heatsinks to remove the ridges in the metal and eliminate air / grease pockets.

I recently upgraded my system to a P4 1.8Ghz on a Soyo Board.
And the temp program that the board came with reported the the cpu was 74

It might be neccesary if you want to improve cooling and still use the factory fan and heatsink. They're often ridiciously out of tolerance. I have access to a granite surface plate so that makes lapping relatively easy. You need a PERFECTLY flat surface and a fine sandpaper. Place the sandpaper on the flat surface (a sheet of glass works fine for home lapping) and then place your heat sink on that and gently sand it. You'll quickly notice if there's any high or low spots by the sanding marks. Sand until the whole heat sink makes contact with the sandpaper. I use 600 grit! You could probably get away with 300 though.
