AMD athlon 64 x2 dual core 5200+ temp rises above 100 Celcius!!

[DanF]

Problem is as described.

Background information:

System is an ACER and for the past 2 years had overheating issues during the summer period. Fan keeps on increasing its speed then it will auto shut off at 90C.

What I've done is changed the stock cooling fan and heat-sink to a more 'complex' (Spire) third part heat-sink. Nothing fancy but the fan is larger and thought I'd give it a try. I've also set the BIOS to default settings just in case some settings were messed up.

Conclusion:

Simple. Still experiencing the same problem. Strange thing is that now the BIOS is set to auto shut off at 90C but it kept on rising above 100 C... when I've obviously turned it off to avoid damaging any of the components. Chassis temp, remains at around 30 C, so it's pretty good considering the temperature in Malta is around 35 C.

Till now I've always managed to solve over heating issues by removing, cleaning, replacing thermal paste, and re-installing it (heat-sink).

Would appreciate any help! Thanks a lot.

EDIT: This is confusing. System information is reporting to be running at 60 C, but the BIOS was reporting it at over 100 C. Ever had this happen? I'll check the BIOS again.
EDIT 2: Nope, just turned off again!

First check the mobo manufacturer for any BIOS updates. Overheating issues have been fixed with other brands, maybe this will too.

Could be a bad sensor too, but I would check the bios update first.

I've thought of updating the BIOS, I still have to check for any updates though. However, the problem is that I don't really want the system to turn off during an update as it would screw everything.

EDIT: there's an update.
EDIT 2: Stays on for longer with a huge fan on it.
EDIT 3: Managed to update to the latest BIOS, but still turning off.

Nothing!! At idle it stays between 55 and 70 Celcius, however when downloading, installing something, or even scanning for viruses it goes up to 100 Celcius (one time even at 125C and then it shutdown).

Can't find what's wrong. Do you think it's the motherboard of CPU malfunctioning?

 

[DanF]

by the way, the heat-sink really feels hot so much so that you can't even hold your finger tips onto it. So it's really getting that hot.

Stupid question, are you sure the cpu makes full, clean contact with the heatsink of the fan ?

If the fan is running at normal speed it should be removing some of that heat. If the CPU is not overclocked or overvolted or something it should be running in at least a normal range, not 100c.

btw- I have three machines here running that same CPU 24 hours a day with stock coolers so I can tell you its not a normally hot running chip.

 

[DanF]

It's almost impossible for it not to make direct contact, considering how the heat-sink is designed.

It was doing the same with the stock heat-sink and the same with this new heat-sink. I've removed the back plate, the supporter bracket and re-installed them just to make sure.

It's not a 'stupid' question, I thought about it as well. But if it's not making direct contact, how is that even possible? It's really strange!

The hard disk was also really hot I couldn't even hold in my hands. Now I've added a cooling fan just at the front of the chassis and is running a lot cooler. Right now I've disabled the Smart Fan Control from the BIOS, so it should run at a constant high speed all the time (as far as I know). Correct me if wrong.

The system is an Acer Aspire M3200.

I will keep you guys informed.

Check the voltage requirements and drop the voltage to the CPU if you can. May cut some heat a bit, yeah I know doesn't sound right, but I've seen it help a laptop or two here and there.

The Smart Fan Control did the trick

During a 4 hour run:

Minimum Temperature: 36 C
Maximum Temperature: 70 C

This is a desktop, right ? Are you saying the fan was on demand up until now ? If so I can't recall the last time I saw a modern desktop with an on demand fan. Speed control, yes, but on/off demand ?

Did this just turn the fan on all the time or is it going full turbine all the time now ?

 

[DanF]

Not sure if I got your question right, but all it does is that it keeps the fan running full speed all the time. At least that's what I think cause I can barely hear the fan even though it's running faster.

The fan was always on during the problem.

I thought you were dealing with a laptop !
