AMD 2100 getting too hot.

I am having some trouble with one of my pcs. Its a AMD 2100 and it is not overclocked but its running at about 65-68 degrees celcius. It was running much cooler a while ago, and when I put any kind of load on it, it freezes up and I have to shut it down to cool off. I dont want to fry the processor, so do you recommend that I get a new processor fan? What do you guys (and gals) think could be wrong? I have a Thermaltake M.I.T fan (that came with the computer) on it right now. It just started in the last weeks to get this hot.

I suggest getting another fan, if the existing fan fails to cool it properly. Did you add a videocard or 7200 rpm HDD lately? Those are also heat generators.

Is your fan spinning? Does it makes a weird noise? Is there dust blocking air vents?
While I did computerrepair, I saw portable's with sandwiches inside. Desktops with sand in them. Desktops with coffee and sucker inside... just to say look inside what's happening. Look to your heatsink, is it still attached properly, does it make proper contact with your cpu?

VictorKaum: The inside is a little dusty, but nothing is really bad looking. The fan is spinning. No weird noise, no dust blocking the vents. I havent touched the system since I got it 6 months ago. I have not taken off the heatsink or fan, but it feels solidly attached to the processor. I might try to reseat it to see if that changes anything.

Strange, do you have some cpu fan indicator proggy that monitors your fan speed?

I have not checked in the bios for the fan speed yet. I will try that in a sec.

Well the motherboard says that the CPU fan is spinning at 0 RPM. I can see that the fan power is attached to the motherboard. I watched the fan startup and its starting pretty slow. I will probably just end up replacing the fan. It looks like that might be the problem.

Hi CXG....I do not have a 2100 myself. I have two 1900's and one each of 2200 and 2400. OK I have a 3000 an 3200, but have not built these last two yet :D I find that I can run a 1900 at around 42 Celcius and the 2400 at around 46...................OK I have overclocked things in my time, but your temperatures seem way too high to me?...I guess you are not overclocking? (please ask, if you do not understand what mean by this term..not what it says in the
books :) )_

I love AMD processors, but to give Intel their credit (and about $250 extra), they do tend to handle temperatures better?

Did you use the fan that came with the AMD?...........I bin them and get some good stuff...I am over here, and you there , so names may not mean much?..tell me what you guys have available? I tend to use "Cooler Master".

The white thermal "gunk" that comes with the pack, is pretty useless...You need to use silver based thermal compound ( better on the way...........but you will have already fried the chicken?)

If you look at the heatsink/processor assembly...do you see gunk coming out round the sides?, this means that the thermal compound is bleeding, and may be compromised?

We also need to consider case geometry and airflow?...what case and fans are you using?

Give me a few answers...and I might be able to help........there are other solutions...but would you really want to worry about icicles, because your processor was running at minus 15?

Keep us informed please,

Cheers,

Johnno

Nope, not overclocking. The temp starts around 50 and goes up a degree celcius about every minute. I am not going to start it again until I get a new fan/heatsink combo.

I dont see any gunk on the sides of the processor, but I have not taken the heatsink off yet. I will check in a bit. Its a standard case and the processor is set about 2 inches below the power supply. Other than that, it is far away from everything. I do have one casefan blowing out, but this has been the same since I purchased the system. I am thinking that I might as well go ahead and replace the fan.

OK CXG.

I would go for a case fan on the side....you may have to cut a hole...that SUCKS air in to the CPU/Heatsink area..........and get an overall box EXHAUST fan.....usually sits down the bottom and gets rid of about 40cfu/m?

Front fans seem pretty useless to me.

Add an extra 60/80mm exhaust fan at the rear.

Also make sure that cables are not interfering with the airflow?..the flat ones?

Not sure where you are, but unless you are building racing machines, with all the bits.............you have to expect about 12c above room temperature?

Nihil, if he's never going to overclock and not pushing his memory, nor his cpu, nor his graphic card to the limit, IMHO he doesn't need that much work, since a while ago his box ran perfectly smooth and cool. I would get a new cpu fan from a decent brand (PAPST) together with a decent heatsink (Alpha or SLK-800 or SLK-900) sitting on the cpu with some silver thermal conduct. A fan at the side would help a lot, but it's probably not needed here. Just a good cpu cooler and an extra exhaust fan would be fine. Perhaps an intake fan at the front to cool the harddisks.

It is an exaust fan in the back. I took off the fan and it looks like the red wire is smashed. Maybe enough to make it run slower. The outer part of the wire is not broken, but it is smashed spretty good. It almost looks like the fan hit it. The cables are clean and are out of the way. And the air conditioning is on all the time. The hottest it gets in here is 80 degrees fareinheit.

Hi,

Farenheit to centigrade.....I guess that you should be looking for no more than about 110f or around....46/48c..................never was much good at mental math :D :D :D

You need a fan that cools the power supply (this will usually come with it, and is situated at the rear of the box). There is usually another fan of around 80 mm at the back, this ususlly sucks OUT.

You may also have a fan of 40-80mm at the front, that also sucks OUT.............this is a pretty useless combination. The one at the front should suck IN and the one at the back should suck OUT.

I would suggest getting new fans and cleaning any airflows

Hope this helps

If you cannot get within 15C of air temperature.............please keep this thread going, as I have obviously failed to help this time round.

Cheers

I had the same problem. I removed the fan and used alcohol to clean the fins of the heatsink and the fan blades (both sides...required separating the fan from the heatsink plate) and immediately got a significant temperatue drop. It takes 15 minutes to do and is by FAR the cheapest alternative. 2 drops of oil via the underside of the fan got a 700 rpm increase in the fan speed, which had also suffered due to dust.

I had bought a new computer through Office Depo. When I started it up, the system would shut down before anything would load. I called the tech support and we went through about 2 hours of this and that. Finally, they said the image was bad and sent me system recovery discs which did not come with the unit, but was in the program and could be loaded to cd. But how with no image, right. Well, I waited and told myself to "pop the hood" and take a look in side. There was a wire pushing on the blade of the fan of the cpu. I moved it over and started it up. It started working and I've been having fun ever sence, and I got recovery disc from compaq too. All because of a wire. You said a wire was smached. Fix the wire and do what 'allend 1963' says. It sounds like a cheap way to go, and sounds like it would work.

interesting timing on this thread!

I just tried to update a kernel on a dual boot machine, AMD 2100+, ThermalTake Volcano 6cu+ CPU fan, w/case fan.

When I did "make modules", it failed with
"internal error: Segmentation fault
Please submit a full bug report,"

So I wiped the source, started again, ( same config ) and received the same error only with a different module in a different directory, one which had compiled with no problems before!

booted to M$ XP, ( to use motherboard utility ), checked CPU temp during normal operations, 65 C

ok, time to clean .... vacuumed inside and case filter, rebooted, now 60 C

Pulled the cpu cooling fan off, disassembled the heat sink/fan, cleaned it out ( alot of burnt stuff in there )

Put it back together, under normal operation again in XP, 50 C

Booted back to linux, no problem at all completing the kernel build!

Guess no use to bother bugzilla for this one!

When the computer says 0 r.p.m that is not a good thing. R.P.M. stands for revolutions per minute, generally the more rpms the better. At 0 it means its not moving, which means eventually your box is going to burn out. Get a new fan, and prob heatsink

Keep with the replacement of the CPU fan, .

As for extra cooling.. the trick is Air flow.. recommend
PSU fan - blowing out..(standard)
Rear case Fan - Blowing Out (If space permitts.. also recommend switched)
Forward Case fan - Blowing in, this one has an extra purpose of aiding the cooling of the HDD, as well as boosting the air flow..
Side Case fan - Blowing In - Optional..

Air inlets have dust filter's fitted.. that is all passive and active inlets.. Less dust, longer life for the internal fans, cooler system.. happier owner..
This currently works for my 2000+ system has survived one summer.. where day temps average 36 degrees Celcius through December/January with some days hitting 42.. and the CPU? managed to stay below 65deg on the hotest days.. BAD ? no..

Check this thread for the post from IKnowNot .. good info regarding these cpu's

http://www.antionline.com/showthread...hreadid=247369
My cpu's Core temp is rated to 90degs

Cheers

Just to keep everyone updated:

I put in a cheap heatsink and fan and the temp is down to 51 degrees Celcius. I am going to replace it with something better, but I needed something to keep it running for the next couple of days.

Thanks for your help!
