Title: Odd problem
Post by: DavidA on December 07, 2015, 02:26:56 PM

I decided to have another go at Linux and have downloaded LucidPuppy Linux.

The down load and burn to a CD wen without a hitch. And the CD booted the machine as expected.

As this was the first time with Lucid I was feeling my way around the OS and thus turning the machine on and off fairly frequently. 

I began another run.  The screen showed the files loading as before. But then this appeared.

Computer has already reached the critical temperature of 64C and will be shut down.

And it methodically shut down. I waited a few minutes and tried again. Same result.

So, I booted up in XP and waited for the machine to shut down. It didn't.

Back to Lucid. Shut down again.

I took the covers off the machine and re started it. Both fans running.

So, left it running. That was, let's see, 14 minutes ago. It's still running.

Now, it does look as if the processor must be running close to its 'critical' temperature (as far as Lucid is concerned) but XP isn't so fussy.

My question is 'Does anyone know of an XP or Linux program that displays the processor temperature ?

I suppose I could just leave the covers off.

Dave.

p.s. It's still running.

CPUID HardWare Monitor should do the trick.  http://www.cpuid.com/softwares/hwmonitor.html

Lew,

Thanks for that. I'll give it a try.

Dave.

For Linux you can use Psensor, http://wpitchoune.net/blog/psensor/
Its in the Ubuntu software centre and the site above gives a number of repository's

I think I may have found the problem.

The CPU cooling fan arrangement is solid with dust. :doh:

At first glance, due to the rather bad lighting in the room, it looked ok. But today I took the assembly off with the intent of trying another processor; then the dust became obvious.
I'll take it in to work tomorrow and blow it out.

I tried PUID Monitor on my laptop and it worked fine.
When I get the tower sorted out I'll download it to that also.
The laptop runs at 44C.

Dave.

 Yes, that cured it.  All that trouble caused by a blocked fan.

I downloaded CPUID to that machine and the CPU runs at around 30C.

So, XP re installed.  I've lost my other applications that were on the Hard Drive, but I can get them back. Most of the data files were backed up.

Oh the joy of modern technology.

Thanks for the help.

Dave.

Oh yes, Nearly forgot.
Tomorrow (Friday) I retire for the fifth and, hopefully final, time.

JD,

In preparation for my time 'relaxing with my feet up' I spent a couple of hours in the shed today bypassing the electrical circuitry to the motor on my Denford lathe. I just wanted a direct connection to the three phase supply to see if the motor would at least run. Last time I tried using the full control board it knocked out the RCD trip.

Going to need that lathe in the near future. :thumbup:

Dave.

Just for the sake of accuracy I should add a correction here.

It wasn't the RCD that tripped out (as mentioned in the above post) it was the 16 Amp current overload.
