Making RC5 client NOT take 100% of the CPU

I just got a new laptop with a P3 850. It runs RC5 nicely. The problem is that it has a noisy cooling fan that turns on once the CPU reaches a certain temperature. Normally, it turns on about every 30 minutes. With RC5 running though, every 5 minutes. This is annoying. Is there any way to have RC5 only take about 50% of my cycles so the fan doesn't turn on as often?

The good news is that my office is staying very toasty warm with RC5 running.
 
Rickr,
Is it a Dell?

I've got a Dell P3 750 that has a noisy fan that kicks on a lot, after awhile I got used to it! 😉

What O/S are you running? In Win, I don't believe there is a way to restrict it to using only 50% of the CPU. (I had asked this a few months ago myself concerning an NT Server 🙁)

There may be some utility out there that will do what you want, maybe one of the other members can help. 🙂
 
There IS a feature in the client where you can make it pause when a certain temperature threshold is met. If you make the temperature threshold for the client slightly less than that of the cooling fan, this problem should stop. I don't know how to find out what temperature the cooling fan kicks in at, though.
 
It is indeed a Dell. It has a fancy air grill on the upper right and two fans underneath---it makes a lot of noise. I am running Windows 2000. I have tried the temperature threshold, but I don't think it works on this system. I've set it to 75F, which means RC5 should not run at all, but it does.

I'm not going to run RC5 on this box. It appears the noisy fans only turn on about once an hour with no RC5 and every 5 minutes with.

 
thats really odd because if anyother application is not using CPU cycles windows does 🙁 even it your not running RC5 your CPU is still running @ about 100%. I have proven this with a CPU monitor (kernel toys). FYI. but I dont know of a way to get it to not use 100% of the slack.
 
On Windows 2000, the "System Idle Process" takes the unused cycles. I believe this is the same type of deal as the cpu idle programs (like Rain) under win98.

Running RC5 turns this laptop into a space heater (that is exactly what it sounds and feels like).
 
No way to do it huh? It would be nice if there was any way to reduce the amount of CPU time that the client takes. I think I might be able to assimilate some machines at work (Intel, SPARC) if they knew that not _all_ of the CPU time was going to be sucked up by the cracking prog.
 
The system idle process is not like a normal program. The CPU isn't actually getting any computations, just waits. It doesn't suck up as much power and doesn't generate as much heat.

Doesn't the Dcypher(or process tree or whatever it is) have a percentage use option? Don't waste ALL those process cycles, just enough to keep your sanity. ;-)

I work in an IT dept and have to upkeep a bunch of desktops holding hardware locks(NetOps won't let us put them on the servers, so I have to have alot of computers running under MY supervision under MY desk and serving up hardware keys to a network takes almost no CPU time. ;-) I have 5 computers running under my desk(1 for building installs, documentations, and to test apps, 1 for my e-mail and databasing, and 3 for keys). Where I sit is about 15 degrees above the rest of the room(70 fahrenheit) due to 100% usage on all 5 machines 100% of the time. I just suck it up and suffer. ;-)
