AMD Cooling tips?

Message

I'm not too sure if this is normal for all amd's but I hear my cpu is running hot. Last time I checked it was at around 70C. I have a nice fan and everything but I dont know where to go from here. I used the goo that they give you with the fan. Ive even added 3 more case fans for a total of 4! Any sugestions?

Are you sure you've measured correctly? I use an (expensive) Zalman copper cooler for my Athlon 64 3200+, with the fan running at minimum speed. The CPU temperature varies between 10 and 24 degrees C above room temperature, depending on the load. The latter is only reached at an extremely high CPU load. There's only one case fan in my box (Verax, totally silent). As the Zalman cooler was quite costly, I'd probably go for an Arctic Cooling solution today.

Even with the stock AMD cooler (if properly mounted), the temperature should not rise above 50° C IMHO. Its disadvantage is noise rather than bad cooling.

Where are you "hearing" your temperature? If it is in the BIOS or software you could have a faulty sensor, or your BIOS needs an upgrade.

I'm using Zalman AlCu something (CNPS7000A). It's pretty good. My machine has always 100% load (running distributed.net client). Temperature is around 40 C. I think that the default coolers are for ppl who dont use their CPU's very match.

normally the stock cooler should do the job, it won't be the best result, but 70 is TO HOT.
So what I would do is
check if you heat sink is correctly installed(I knew someone who place en sensor probe between his heatsink and cpu, which caused the sink and cpu losing contact, and then the temp was about 70 degrees)
1) check that the power connector of the fan is connected and that it actually spins when turning on the pc
2) also check the case temp, it shouldn't be over 35°
2) heatsink and cpu much be making contact all over the cpu's surface
3) there should be some cooling paste between heatsink and cpu
if all this seems correct, chances are you have a faulty sensor, one more check you can do
4) let your cpu run at 100% for about 10-15 min, then touch the heatsink, if the 70° is correct, you'll only be able to touch it for a short time

normally with the stock cooler and the 4 case fans you should be able to run your cpu at less then 55° C
unless of course you have 6 hard drives installed and dual graphics cards

I get ~50°C with the stock cooler slowed down to ~2500rpm...

I Have a CNPS7000Cu which does a realy great job. ~50°C and its quite as well. But the whole comp is still too load i think because of the radeon.
A long time ago i had ~40°C but since a BIOS update it gives me exactly 10° more than it showed before.

mime is about 40-50C

Thermalright XP120, it's much better than those Zalmans.

Mine was also about 60 - 70 c, when i bought mine but after an bios upgrade it is about 35 c when idle...

you have to update the BIOS.
Probably the temperature of your chip do not get so high. One feature of athlon64 is that it turns off if its temperature reach 70C or higher. This feature is independent of the motherbord.

hmm...everyone here is right about 40-50C...are you overclocking though? It sounds like you are. I know that if I set to overclock even 5% that I go from about 44C to ~52C...

You guys must be living in the middle of the desert or something

The highest temp my cpu has got up to was 46C and that was after a stage1 install with the default cooler. Ever since i got a Zalman cooler the darn thing has never got higher than 42C

I have the AMD cooler given to me with the CPU and a 120mm fan installed too (no other fans), my box gets maximum 42 degrees... and I'm supposed to live in a generally warm country during winter!

two words: emerge athcool
read up about it -- it's probably a MoBo setting problem. I was running 70C idle, and now run 38C idle.. no hardware changes.

My amd 64 stays around 40-52 degrees C with one side panel of my case open. When I fully close my case though I have seen the CPU rise to around 65 degrees C.

That program's not designed for any amd64 motherboards in existence. Not to mention it's using an outdated list of chipsets for amd x86 boards.

I get that If I set my memory/bus speeds manually. I just set it at auto and all is good even though I know it can go faster I only incur about a 2% performance penalty, if that.

In my case I think the culprit is my massive (and heavy) FX 5950.

Try to set the motherboard back to defaults and check the temp again.

<3, you really need a better case, in my old one, when I closed the case the fan of the cpu was screaming, I now have a chieftech BX-03 and it is as cool as I mentioned above just by adding a 120mm fan to the back of the case.

<3 · Post by <3 » Tue Nov 30, 2004 3:24 pm

Yea I figured it was the case. The one I have now is so cheap. I found it on ebay for $25. I am in the process of saving up for a good case but a good case can be expensive.

If you don't wanna go crazy and buy a Lian-Li, try the Coolermaster ones. I have a Praetorian wich was at a nice price (~80), it has 5 fans and it's very quiet despite the number of fans. Also the layout is very good meaning you won't have to disassemble everything when you want to do something inside.

koroumel · Post by **koroumel** » Wed Dec 01, 2004 9:08 am

Mine is in about the class described by malloc (by the way... strange nick!).. and I bought it 80 (VAT included). Believe me, what you pay is what you get. A friend of mine has a Lian Li... and not only it is cool, but it is very light too (aluminum).

Have a look at chiftech site, they make good cases, and the photos of their cases can give you a picture of what you should be looking for.

If the computer is still running and not crashing, then it's not too hot. Don't panic.

My CPU runs at about 70C because I use one of those SFF cases which are tiny and have barely any room in them so everything gets hot. The temperatures in there are high, but it still all runs fine and doesn't crash unless I drop the fan speeds way down.

If the computer is still running, then don't worry about the temperature. Athlons (these days anyway) are very good at shutting down when things get close to too hot, so even if your CPU were to go above it's comfortable temperature it would reboot the PC before ay harm got done.

Well it's a bit better than calloc or realloc

Btw i forgot to mention that the Praetorian is also aluminum,it's the lightest case i've ever touched. The day i went to pick it up i had pulled one of the lower back muscles so i couldn't lift weights, when i got it i made about half the force needed to pick up normal cases and the damn thing almost flew out of my hands, so it's very light.

Yes he needs a better Case.

But why is everybody using this Chassi-Fans??? I never get over 50°C without any extra fan....

But I'm using an Fortron Silent Power supply with 120mm-Fan looking down to the CPU. Maybe this is the case that I don't need any further fans...Bought this because it's really silent...
