Topic 191187
(moderation:
Is there a way by via programming, to reduce overheating to the max without reducing performance ?
Are there some strategies ?
I my case, i use an athlon 64, 3000+, Winchester(90 nm)
Instructions :MMX, Extended MMX, 3DNow!, Extended 3DNow!, SSE, SSE2, x86-64
my mothercard is MSI MS-7093 and i actually use the optimised einstein@home 4.37 "alb_S4107.zip" (SSE)"
With this client,i achieve 60° when he is running, otherwise the temperature is about 50°C

No. CPU temperature is a factor of how hard your processor is working. By running a program tht holds it at 100% you're giving it a maximum strength workout.* If you're concerned about high cpu temps your options are to either reduce your cpu's load or improve it's cooling.
The former can be done by either physically slowing it's maximum speed (generally not possible with oem computers), or limiting the cpu share einstien can take. i'm not sure how to do that, IIRC it can be set in the registry. Try googling, or wait for someone else to reply.
The simplest thing you can do to improve cooling, especially if your computer's been around for a while is to open it up and clean all the dust out of the fan grills, off the fan blades, and out of the spaces in the heatsink. If you have room for additional casefans putting new ones in can help somewhat. Adding a better cpu cooler can also help but will be more expensive ($30-50 vs $10), and will probably make your system louder than it was before since higher performance units generally combine larger heatsinks with more powerful fans.
* as an aside, not all 100%'s are equal, due to pauses when data needs fetched from slower memory, einstien fits entirely within the fastest L1 cache on and amd chip, and akos's app is optimised to the point the cpu's runing at nearly it's theoretical max.

60 degrees is hot, but not dangerously so. I wouldn't worry about it. My Athlon XP2800+ runs at around 55 - 60 degrees (depending on how hot the air in the room is) when running Einstein. So far I haven't seen any system instability / failures.

Ditto.........on a nice cool day I can get around 50 degrees under load with the same processor.
When the sun's out.......it hits 60/61..........if it does that I tend to set it to work based on preferences (only when idle) rather that all the time.

I am using an Asus MB (P5WD2) with a P4 3.2 GHz (Prescott) with HT. I have been battling temps of 60°C at idle and 78°C at full load. Mostly running Seti@Home, but some Einstein. Cleaned all fins, and case fans, etc. to no avail.
Today I installed a Zalman CNPS9500 AT CPU Cooling fan. What a difference! Now I have 60°C at full load, and only 48°C at idle. I am not running all fans at full speed, either. I have the fans under control of the BIOS, in "optimal" mode, and most of the time the fans are slowed down a bit, and the PC is nice and quiet.
Best $50 I ever spent I think. Newegg.com had em on sale.

If your cpu is running hot or the fans making too much noise and you cannot change them, there is a program called Threadmaster out there that allows you to specify how much of your cpu resouces a program can use.
I personally have never had to use it but some people on Seti use it. The only problem I have seen is you have to add new setting each time the application is changed.

I have the exact same CPU + a gforce 6600gt in an Antec Sonata case without front Fan (pretty low airflow inside the case). I replaced the boxed cooler with an cheap (10$) but slightly better one (some 'arctic cooling' iirc)
At stock speed and ambient 20C i observe about 50C idle and 57C with E@H.
After thorough cleaning of the cooling fins and some new (and better) thermal grease the system is now running E@H-stable with 10% overclock (0.1 V overvolt) at 62C.

On the request of paulatreides, BoincStudio is now including boinc throttle to reduce overheating. See BoincStudio topic.

60 degree is ok. You might want to use a Zalman CNPS 9000 (http://www.tfun.org/modules.php?name=Forums&file=viewtopic&t=307)
It works great for all processors.

60°C with a stock 3000+ Winchester? Oh boy... :D
When I had mine running at 2.7GHz it was approaching 50°C under load with a Thermalright XP120 + quiet 120mm fan, which is by far not the strongest heatsink today.
If you have no case fans installed I suggest 1 or 2 low-medium speed ones (3 - 7€ each), e.g. 2 x 1500rpm or 1 x 2000rpm for 80mm. The Enermax units are nice, because you can choose the speed yourself by turning them down until it sounds comfortable (and a bit later turn them dwon a bit more..). If you'd like to run at ~45°C with a >2.4GHz clock speed, as it would be normal for such a CPU ( :D ), you'd probably need to change the CPU cooler. The "Arctic Cooling Freezer 64 Pro" is a quiet and strong performer for just 15€.
Otherwise 60°C isn't too bad. But really, an A64 at 1.8GHz is so easy to cool...

Most processors are able to run with 0,1 or 0,2 V under their default voltage.
