Is there some sort of Program out there to control or limit your CPU speed. My computer over heats when I use the program.

Some people have spoken of ThreadMaster, but I do not know how it really works. It is here: http://bednorz.uni2.net/anyland/threadmaster/threadmaster.htm Reading the site, it says that it does not work with Windows NT 4 but does with Windows 2000 up. It is supposed to allow you to set a CPU percentage usage limit for a process. I have never tried it, so use at your own risk.
If your motherboard supports monitoring (most modern ones do), you can use a free program such as MotherBoard Monitor to check your CPU temp, or check with your computer's manufacturer/motherboard maker to see if they have special software designed to do it (most individually purchased motherboards are bundled with utility software that can do this).

OS: Windows XP Pro CPU: Pentium lV 3.2 GHz For the record, if your computer is overheating, you have other issues. On a system that new (3.2ghz has not been around that long), you should not be overheating unless you have an inadequate cooling setup. You would be wise to invest in a high-quality cooling system for your computer, even if you find a way to limit the WCG processes, ortherwise you're going to come across this issue over and over. I recommend visiting gaming and overclocking websites to look over high end CPU cooling fan reviews. |

Or a bad option, but as a last resourt is to have WCG snooze more... if budget is an issue or something...

Hi,
I have the same setup and measured tempertures in idle mode of 140 degrees f and 195 degress f when rosetta was running.  I tried everything including a 5000 RPM case fan to no avail. So I resorted to watercooling the processor. Now in a 75 degree room the processor under full Rosetta load runs at 96 degrees f. My northwood 3.0 ghz processor with a stock cpu and case fan running two climatepredition.net workunits simultaneously, runs at 100 degrees. These workunits on aveage take 760 hours to complete. So I am personally very dissappointed with the prescott cores and plan to have just the 3.2 and 3.4 both watercooled only. |

I think I have come up with a solution to the overheating problems experienced with the P4 3.2 ghz processor. Today I replaced my stock Intel heat sink and cooling fan. I replaced it with a heat sink/ 80mm x 80mm x 25 mm cooling fan with an rpm of about 3500 and a cfm rating of about 42 that cost about $15 from my local electronics store. In addition, I duct-taped a standard 80mm x 80mm x 25 mm case fan to a round IDE cable running between my 5 1/4 drive bays and the CPU, about 4 inches from the heat sink. The combined heat sink/fan and the jury rigged case fan lowered my CPU tempature about 16F to 20F, from about 147F to 127F to 131F

Here is some additional information about my heat sink/fan assembly:
Manufacturer: ATT Model: IRO2 Retail Cost (what I paid for it): $14.99 US + Sales Tax Heat Sink Material: Copper and Aluminum Heat Sink Dimensions: 83mm X 69mm X 36mm Thermal Resistance: 0.43 (degrees Centgrade/Watts) Fan Demensions: 80mm X 80mm X 25mm Rated Voltage: 12 VDC Rated Speed: 3400 RPM +/- 5% Air Flow: 46 CFM Noise Level: 34 dB Copper Weight 310g +/- 5% Clip Force: 201lb +/- 5% CPU Application: Up To Intel P4 3.6 Ghz |

I ran a 3.2 and 3.4ghz prescott with an upgraded fan setup 24/7 for 4 months on this and another project. I just got to tired of the noise from the prescotts coupled with the normal fan noise from the other computers. After listening to these things for months I decided the expense of watercooling was worth it to get a bit of silence. Which I have now and I am very happy. unless your going 24/7 though with the sockett 755 stuff watercooling is overkill.

Another option that you could try is underclocking your cpu if your motherboard will allow it.
The power used by a cpu is proportional to V^2 * Freq. When underclocking your slowing your processor down and by the gates switching less your using less power and generating less heat. And some motherboards allow voltages to be lowered saving you even more power. But if you lower your voltage definitely slow the clock speed down or else your system will become unstable. |

I really think your problem lies in the heat sink/fan or case ventlation. I have the same processor (Intel 478 Pin P4 3.20E Ghz 800 Mhz FSB) and I replaced the Intel stock heat sink/fan with a heat sink that has a larger fan (specs on the heat sink/fan already posted above). I have a mini-tower case not designed for 3.2 Ghz but I have installed an 80mm x 80mm x 25mm case fan in the lower front in a slot designed for such fan. In one of the PCI slots I installed a turbine exhaust fan. In one 5 1/4" bay I have a hard drive cooling fan (two small induction fans on the front of the hard drive) I have taken two ordinary 80mm x 80mm x 25mm loose case fans and duct taped them within a few inches of the CPU/Heat Sink/Fan, one between the 5 1/4 bay and the CPU and the other 45 degrees to the right of the first loose case fan. With this amount of air circulation generated the CPU has been cooled down into the upper 120 F degree range, acceptable tempatures for an air cooled P4 3.2 Ghz processor and much cheaper than going to water cooling (and no worries about future problems associated with water cooling such as leaks and pump failures).
