Overheating PC?

MarkNorfolk

Hi

I have a Packard Bell OneTwo all-in-one PC which has recently started going dead after a while of use using Windows Media Centre. I've used a temperature minitor and the Core 0 temperature seems to get up to the high 60s/low 70s. I've opened the (hard to remove) back panel and the fans seem to be working OK. I installed Speedfan but it doesn't detect then fans. The warranty expired in late July.

Any advice?

Cheers
Mark

While you opened the back panel did you see lots of dust. Remove what you can carefully and preferably with a can of air. Test that. If that helps great.

Otherwise, go into your BIOS and try and increase the fan speeds. Your motherboard or PC manual may have had some software that can do this for you actively.

PBell............well they do have a habit of falling part after 12 months I'm afraid - the PB forum is full of it.

However on a more constructive note, if the previous posters suggestion of cleaning out the dust doesn't resolve the problem - I would recommend replacing the CPU fan (and heatsink if you need to) - it often happens that the dust creates a sort of "goo" in the fan motor and it just doesn't rotate as it should. I would at the same time as replacing the fan remove the heat sink, clean the old cpu thermal paste off the cpu and heatsink and re-do the thermal compound - plenty of info on the web on how to do this.

If you have animals in the house dust becomes a much greater issue, especially equipment that has fans which tends to draw the dust in.

Expiry of warranty doesn't affect your rights under the sale of goods act, which says goods have to last a reasonable amount of time

70C isn't massively hot. Not ideal but certainly not hot enough to shut things down unless someone has been over-eager in setting a shutdown temperature in the BIOS.

This is technically correct, however any CPU running over 40C probably needs cleaning. Secondly even if you did lift the temp cut-off in BIOS there is a risk that it just gets hotter before it cuts out.

The 70C was set at PB for a reason, ie to prevent damage. So I would do the cleaning as suggested earlier.

If the 70 is an idle temperature I would be concerned less so if it was while under load.

Rubbish. Most CPUs do 40C at idle.

This is too late for you I think Mark, but if anyone else is having this problem the best solution is the remove the inner metal casing over the motherboard.

you wont be able to wall-mount the pc afterwards but it will go from the worst ventillated machine I have seen to the best ventillated, and temps will drop sharply.
