CPU @ 51oC

prospect

Hi,

My P4 laptop is running at a temp of 51oC according to MBM5 which i downloaded today.
I checked this out quickly on the inet and it seems normal operating temperature for a P4 is 36oC.

The fans all seem to be working normally, and they only come on when the CPU temp goes above 51oC.

How do I set the fans to come on at a lower temperature?

Thanks.

if you have had it running for some time, you might need to change the thermal compound.

Nope,

8 hours a day, 5 days a week for a year and a bit now!
Less Saturdays, Sundays, Bank Holidays, Annual Leave etc.

On a laptop, it's not really possible to add more thermal paste.

These are the optimal temps Intel recommend

But in a laptop they may run hotter, I have seen them go up to 58 degrees and work fine.

Unless there is a Bios setting to adjust fans in a laptop, there is not much that can be done.

There is more info here on what can be done to cool it down a bit

Laptops are like a fortress to dismantle....easily 60 or 70 screws to remove.
Most of the time if you dismantle one you'll probable end up breaking them.

If it's a dell (or some other semi compatible laptops) you should try I8kfan utility. It gives you full control of both the mobo fans and also offers a full suite of temp monitoring for the components.
Not sure if it'll be compatible with your machine...

51' is nothing to worry about for any CPU as far as I know. 36' sounds very low...

if it's dell 5160, they have presscott cpus,

Demon, nope it's not, I have 5150 with a Northwood, runs at 33-40 usually

but my 5160 with presscott runs at 51-55, those cpus are meant to run that hot, so don't worry, the main thing to look at is if it goes over 70 when fully loaded, if it doesn't just forget it

especially dells, they are such a pain in the ***, on most other laptops you just take off the cover and cpu/heatsink is accessible but dell, you have completely take it apart to access cpu, in the manual it says you just unscrew a keyboard and a emi protecting shield and cpu is accessible, but that is so not true, the sides of the laptop cover part of the heatsink and it's impossible to take it out, unless you take the whole thing apart

The laptop is an Acer Aspire 1705.
It has a 17" screen, and because the base is quite big, it uses a good few 'regular' pc components.
I had it open before, (added an extra 512MB RAM), so that isn't too bad of a job. But, it seems that 51oC is fairly acceptable a temp, so I son't worry about it for the moment.

Cheers everyone.

i'd check your bios and see what temps they are reporting there, and then check MBM to see that the temps are roughly the same. Its very easy for it to be reading the wrong temps from different sensors etc'
