rc5+laptop=bad

Yesterday I put the Team AT RC5 client on my 550mhz k6-3+ laptop. I left it on overnight, and it was all good, got some packets crunched... So I went out to eat with my family and when I come home...
The laptop had turned itself off cuz of overheating! Hehe... Boy I feel stupid 😉.

I was thinking about putting SETI on a laptop, but I'm a bit worried about the heat issue. Maybe it's not such a good idea...
 
Well for several reasons, probably the main one being to keep size down, there can't be much of a fan/heatsink on the CPU. Therefore, they automatically run very hot. So if you push it like that, obviously it will be running at very high temperatures, hence the overheating.

Just don't bother cracking RC5 blocks or SETI work units on a laptop, use your home systems for that.

weird. i wanted to test the new fan that they had put in my dad's P200 laptop, i put rc5 on it and let it run for an hour, never came on 😕 didn't get that hot either..
 
It seems to vary from laptop to laptop. Some have no problem with overheating, while others start glowing red.

Ya, it's usaully a matter of a laptop's colling system. Some laptops lack good enough cooling to run 100% 24/7; while others can do it fine. With laptops, it's simply a matter of experimentation.😱
 
leave your laptop on a large metal plate inside the fridge/freezer for that kind of stuff (seriously, it works). No real risk of overheating. just make sure the power cable doesnt leave a crack in the fridge seal
 
My ThinkPad runs 24/7 cracking RC5, and everything is fine. I leave it plugged in so it runs at 850 instead of 700 and also so the fan is allowed to spin to maximum RPM, every so often I the fans spools up, but the fan shuts off eventually, and the computer stays OK. Now that you have mentioned it though, I'll have to check the temp of the CPU, she's been up all day, every day since I got back to Pitt on Wed, this thing has to last another 4-5 years, no sense risking it just to crack a few more keys while I sleep. (Sorry Russ, if I have to give it breaks, I'll still be cracking while it is on.) Anyway, no problems with it so far.

I wouldn't suggest that, putting a hot laptop in a cold refridge will lead to condensation forming on the laptop if the air is moist
 
the &quot;safest&quot; way of doing it is to put the laptop in a plastic bag and tie off the end so that only the power cord is sticking out and no air can get in. Then make a rectangular hole in the bottom of the bag and tape it to the back of the laptop so you essentially have an airtight container, then put the exposed sirface on a large metal plate which has direct contact with the bottom of the freezer. If you are crazy enough, you could take the backplate off the laptop and try to unlock the multiplier so you can overclock it but i doubt anybody could be bothered trying that.

I usually find that just leaving it to sit there is okay as long as you disable the fan and cover it with something
 
I put rc5 on the company p3-700 thinkpad and always have it run when not on battery. no overheating or whatnot. Not mine, don't care anyway.
 
I use to have my HP laptop crack RC5 24/7 for a couple of months but stops cuz it might reduce the life of my laptop..
