Pentium III's and Folding

I wouldn't worry about a lappy with a Pentium mobile CPU. I ran SETI then FAH on my 1.5 Mobile from the day I bought it and I ahven't seen any problems. The only thing to which I suggest you pay close attention is the CPU heatsink. Becasue of the shape of most of them they are very likely to get clogged with dust, hair, potato chip residue, and whatever else is in the air nearly. I find on mine that it happens right up next to the fan so to clean it properly I must remove the fan. It's no hassle and it's wicked fast, at least as fast as a P4 Prescott at 3.0. :eek:

I think i'll give it a go, however i can't really clean the fan out by taking it apart as it uses some wierd screw heads, and it would probably void the warranty. I can still clean it with compressed air.

Also, since i started playing some games on it, the fan has become more sensitive to heat and starts up much sooner than it used to... not sure why.

I'm thinking of putting speedfan on it, and i think the fan control is software based, but i don't want to fry it.

Its an hp nc4010, an ultraportable read small heatsink and fan.

That was the first symptom of mine being secretly clogged deep inside. Using compressed air is just going to toss the crap back inside it.

Maybe your dust is not angry and virulent like mine is. It's what I get for living near to construction sites whilst not having air conditioning in the summer. :rolleyes:
 
You think i have air con in the summer?!

A combination of using halogen lighting and my dual core opteron has caused me have the window open quite often during the middle of the winter, summer is going to be hell.

And as for the dust, i remove cakes of it from the dust filters on the front of my tower each week, the poor laptop hasn't got a chance!

I will have to use compressed air, as i don't think i could get this laptop back together again if i do get it apart.

Its doing well, been on around 2 hours and done 4 percent of a 241 pointer.
 
Heh funnily enough I've just this second finised cleaning my laptop

AMD 3000+
(1800mhz)

As stated a large amount of dust completely blocks the copper heatsink fins.

By cleaning it I reduced the temps from 100C to 50C

Idle temps and full load temps are the same, it makes no difference wether it's working so I figure it might as well run something useful.
 
100c would seem a little hot?

Most cpu's tend to die at around 80, i think the athlon mp would cope with 90 before it fried, but 100... now thats hot!
Are you sure thats not the gpu or something?
Although nothing should be getting that hot.
 
I assumed the highest temp would be the CPU seeing as the GPU would be doing nothing whilst sitting at the desktop surely?

Speedfan just said
Temp2: 100 almost all the time
Temp1 was round 50

now it says Temp2: 50 all the time.
and Temp1 is 32

And yes does seem a tad warm but it's been left crunching for days at a time at 100, besides after removing the heatsink and fan and cleaning and polishing it and using some lovely new AS5 I'm very happy with 50C.

My view of computers is, if they crunch there fine.
 
The only things that will hit 100 without frying are the gpu and the voltage regulators. If it was just sitting at the desktop, then it must have been the voltage regulators, as folding will make them hotter.

I would say that temp 1 was the cpu, and perhaps the voltage regulators use the same heatsink as the cpu, so they also got much cooler when you cleaned it out.

Either way, good to see you crunching.
 
Voltage regulators? Are they the little chips surrounding the Die?

The only thing the heatsink touches is the Die.

I would have thought a an Athlon 64 3000+ (1.8 Ghz) would run a little hotter seeing as my Athlon 64 3200+ (2Ghz) is between 39 and 44 C at full load, depending on how fast I set the fans on the radiator.

50C would be about right now I would have thought considering the rubbish fan that really doesn't move much air at all in any direction and the small completely enclosed heatsink.

I've had a Palomino XP1600+ up to 96c when the fan decided to stop working when I was visiting friends 90 miles away, I couldn't shout "just pull the power lead out of the back" fast enough when my dad told me the temperature MBM was showing and funnily enough it didn't seem to want to respond to being shutdown normally :eek:

Sure enough when I got back and fired it up (after checking fan connections etc) the interval log did indeed show 96c for as far back as it went - but to this day (touch wood) the chip is still running absolutely fine in my mate's computer - bizarre!!! :p
 
The dually is happily crunching away now, and I've just won a P3 mobo off eBay - I have enough spare parts to build a complete rig around it, what with the old 866mhz P3 from the server. So I'm building a bit of a farm, even if they are P3s :rolleyes:

Worried about my money now actually, I need to be saving it atm :eek: No more purchases for a while now methinks.
 
Race is really starting now :D

Joe42 you're output is looking pretty good, I'm getting worried now :eek: Thing is, I can't think of any more PCs I can b0rg - I'm on maximum output (except a Celeron 366mhz which is pointless :p)

Should be fun this :)

Updated cruncher list:

1 x Athlon XP Barton 2600+
1 x P4 Prescott 3.0 (HT - dual clients)
1 x Celeron :( Northwood 2.4
1 x P4 Willamette 1.8
2 x P3 Coppermine 1.0
1 x PM Dothan 1.73
 
Go go go! :D

I'm still struggling to send units, which is a real pain.

Edit: Looking at the log its struggling to recieve rather than send, seems to be sending ok now.

Haven't folded much today, been out at a lan playing TA and getting very annoyed at my laptop, which seems to be dieing...

I abused a Celeron 500 laptop with a broken fan for several months by running Folding on it :p It ran at about 85c. Still works to this day although it doesn't fold any more as it was so slow I eventually gave up with it (two weeks to run a single Tinker?)

Definitely borg the P-M lappy! I make your figures 116ppd which isn't too bad, but get a 364-pointer onto it and it will easily give 400ppd. They rock at them.
