Your processor is getting hot because software like this makes sure that it is running at 100% all the time.

I dont know of a way to reduce the maximum amount of processing power available to a program, short of 'under'clocking your enitre machine..

So the only option you're left with is more effective cooling: try removing any dust from your heatsink and if that doesnt work then improve airflow in your case or upgrade your heatsink...

I think the gentleman who posted the original message is right in being concerned. While PIVs have a degree of 'meltdown' protection that new AMD chips do not, the lifetime of the PIV is remarkably reduced from decades to thousands of hours. Although no comprehensive research has been conducted on catastrophic heat failure, tests have indicated that modern .18, and less so, .16, micron integrated circuits have a life of 1000 to 1500 hours at a sustained 85-95c. If one of your fans stops, its a gonner sooner than later.

Your problem seems to be not so severe but I would't allow my system to burn its processor willy-nilly. This is not Unreal Tournament or Doom or any really important endeavour

My suggestion is to check all your fans, tie up cables, and do whatever possible to get it down below 55c. If it comes to it, rip off the side and point a good 'vornado' or similar brand low noice, high air circulation fan right at your CPU and vicinity.

PIVs just weren't designed to operate at 99-100 load, continuously, without good cooling.

I have been searching for some good articles but none sum it up well. I would reccomend checking out overclocking websites ...

Useful piece of software which I successfully installed following a recomendation from someone else in these forums is Threadmaster.

This restricts the amount of processor time which any given application can use to a percentage which you can choose.

Get it from http://threadmaster.tripod.com

It does involve configuring parameters via the registry, but instructions on the site are reasonably clear.

Although my desktop machine can cope with 100% processor operation, my laptop is not happy with it and gets very hot, so I have wound WCGrid_Rosetta.exe back to 25% on it and it runs nice and cool now.

I accept everyones comments that processors will not instantly die if run at 100%, however, running at elevated temperatures will reduce the MTBF of electonic devices and you are liable to have to buy a new computer somewhat sooner than you otherwise would.

Some form of throttle should be integrated into the UD Agent to allow control of maximum processor usage without having to esort to external programs.

This lack of flexibility, combined with the very long processing times for work units and the continuous resetting problem covered elsewhere in the forums is going to mean that a lot of people (like me) are unlikely to hang around for long unless there are some changes.

Is anyone from the GRID actually monitoring these forums? If so, just let us know you are there!

I don't know how experienced you are with making changes to the system settings, but I'd recommend getting into the BIOS and;

Turning the system clock down from 3Gh (3000MHz) to 2500MHz,

and possibly reducing the voltage to the CPU.

If you're ambitious, check into the overclocking forums to see what is possible for your MoBo. Obviiously, you'll be underclocking, but the principles are the same.

Another idea is to install a better CPU fan/heatsink and get a better case like an Antec.

Good luck.
