What temperature is considered too hot for an Athalon 64 3500+

Building my first system, and I wanna do everything right. I don't plan on overclocking at first, but when there's a reason too, I'd like to be able to. I was wondering what is the max temp the processor should be in both Celcius and Farenheit. Any help on this is greatly appreciated
 
I would go with the XP-120. It is probably one of the best heatsinks available and has a great cooler as well

For the 130nm CPUs it is 70C/160F , for the 90nm CPUs it is 65C/150F.

wow that is really hot! mine idels around 40c ...from all my research they burn at 70c dont they?

These temps are referred to as Tcase and are measured at the center of the IHS.

~70C is when they begin throttling. There is an internal sensor that shuts down the cpu completely at a certain temperature. For the P4 this internal temperature is 135C. Xbit conducted a few tests and a P4 reached this internal temperature of 135C when Tcase was ~95C.


 
I didn't know the AMD 64s throttled, I thought that was just the P4's.

Check each heatsink's motherboard compatibility list. I was surprised when I check the XP-120 and it said it was not compatible with the MSI Neo2 Platinum, socker 939. So I plan to go with the XP-90.
 
I use the XP-90 with a 92mm 50-something cfm Panaflo fan, Arctic Thermal 5 and the V1000 case, but I'm still running around 40 idle. I still think this is a bit hot (some people are getting low 30s with the Zalman flower thing), any help?

Your heat sensor could be fuxed.
 
This is a bit of a guessing game only convoluted evenmore cause of the inaccuracies in temp reporting by motherboards....Get an Abit mobo and your temps at idle can be high 40's...same setup on another board could get you high 30's.....

Generally from my testing it appears just a decent copper core hsf will be suffucient to 1.65v and likely as far as the chip will go.....

If you are getting a retail chip I say wait and test the stock one out...2 things can happen. 1 the chip may not be a good overclocker for other reasons, or you run some high temps...If the latter happens then see how much you need to drop and spend accordingly. I hate to see ppl spend 40-50 dollars on a heatsink and fan when chances are the may have neer reach unsafe temps and their chip was limit by clock anyways....

I tested with a stock cooler for an opteron...for all intensive purposes it is likely fine....idle at 34c but loads prime at around 53-55....loads FH at 52c....That is at 2600mhz with only 1.47vcore...NOw when I bump to 1.63v to get 2.7ghz to run it is like 60c load of prime95...I want the headroom of rising seasonal temps and dusty fans that are inevitable and raise the temps...I have a Venus 12 TT coming...

Seems on-die throttling is not activated yet. Might get activated in E0 or possibly not until dual-core Opterons.



 
I live in a house at a constant 70F, I don't think my CPU would be too hot.

For SpeedFan, which one is CPU temperature? There are like 10...
 
I must have the most disappointing temperatures.

Stock heatsink and fan gave me 38°C (100F) at idle and 62°C (144F) during full load.
XP-90 with AS5 and Papst gave me 37°C (99F) at idle and 60°C (140F) during full load.

I certainly hope that the motherboard reports wrong temperatures (I use MBM5 to read) and the fan is too weak (92mm, 2000rpm, 35cfm) but I'm not sure.
The system measured follows:

AMD Athlon 64 3500+ Newcastle @ 2.5 GHz with 1.6 volts.
MSI K8N Neo2 Platinum in Cooler Master Stacker case (2x120mm in, 1x120mm out)

Maybe it is time to look at water cooling solutions.
 
Doesn't sound too much better than mine though:

XP-90 with AS5 and Panaflo - 35C idle (haven't monitored load yet)

At least you've got a quiet fan, I've got a 2900rpm 54cfm 35dba beast on my heatsink.

AMD Athlon 64 3500+ Winchester @ stock
MSI K8N Neo2 Platinum in Lian-Li V1000 (1x120mm in, 2x120mm out)


You might wanna try flipping one of your fans around to exhaust, you generally want more exhaust than intake. I had mine set to 2in 1out and I got close to 7C difference when I flipped one to exhaust. Just make sure that your intake and exhausts are far away from each other so you aren't wasting air.
 
Mine is 35 C idle with Everest Program. It is 38-40 under load. I have a 3500+ 90nm with a xp-90 and a Panaflo. Oh, and I OC my processor to 2.5GHZ with almost the same temps!
 
toms hardware have videos showcasing the effects of overheating....on the P4 line they removed the heatsink and the cpu throttled back...it was so successful that the computer never even crashed it jus ran really slow until they put the HSF back on. on the P3 even,the cpu shut its self off, ok the computer crashed but everything was intact......AMD athlon on the otherhand well.....they took the heatsink off they measured the surface temp at 300 degrees!!! end of processor and mobo....expensive!

but the A64 has a good throttling system now
 
Which Panaflo if you don't mind my asking?

I've got the same setup with a FBA09A12M - medium speed - and I'm getting 45 idle and 54 under load. Was getting 1 degree warmer with stock HSF but it still doesn't seem right.

I have a venus 12 by thermaltake and its a brute of a heatsink and fan I never go above 110f with my cpu
