You'll get used to that. Trust me.

This made me laugh. A lot.

This may be a silly question, but do you leave your computer on overnight?

Well I decided to leave my new computer on overnight. Previously I did not since it is so loud. Still found no primes in my projects.

Does anyone know what program was used to sieve the primes in the various "drives" here? I tried to have NewPGen sieve them some more and it said something like the entries were out of order.

NewPGen will only handle one K or one N at a time and is only used now for specialist sieves where either srsieve or psieve will not work. psieve is optimised for large numbers of consecutive K's and N's and was used for the 1st and 2nd megabit drives. Note there is no point in sieving these further as they have been sieved to p=80,000T.

My home machine was not turned off for something like 6 years. Of course, there were a handful of power outages, but I wanted to see just how much overclocking would shorten the life of a CPU. I can report that a Celeron-566 ran at 920 for 5 yrs, 850 for 2 yrs, then fell apart and only ran at 675 or so for the last year it was in use. I believe that not heat-cycling the CPU extends its life- if you can justify the power expense, your machine will last longer by not turning it on and off.
I admit I do power mine down now if I won't be using it for 3 days, such as a weekend trip away, but it probly runs LLR 24/7 for 350 days a year.

I went a little overboard, I bought a protyped extreme machine that isn't even on the market. It has a huge heat exchanger on it and a 1 horsepower condenser. It is very, very loud. There are two different gases that mix within the chambers, and the second phase cools the gas exiting from the first phase, and the temperatures are very, very cold.

Overboard, indeed! So much electricity wasted for cooling, it's hard to justify leaving it on for long, or even using it for Prime work at all.
