hi

The temperature in the 64-bit and 32-bit CPU is the difference?

CPU temperatures in Ubuntu 64-bit and 32 bit is the difference?

Sorry I don't understand your question.
If your asking if there is a difference in temperature between 32 bit & 64 bit, I would think the answer is no.

Are you saying that you've tried both and the CPU temp is different between the two?

If so what version of Ubuntu are you using?

Please try to be more specific.

I installed Ubuntu 64-bit version, CPU temperature is high!!


Can I install Ubuntu 32-bit will reduce the temperature?


ubuntu
Release 12.04 (precise) 64-bit
Kernel Linux 3.2.0-26-generic
GNOME 3.4.1
-----------------------------

Intel® Core™ i7 CPU Q 740 @ 1.73GHz × 8
Nvidia GT 425

I typically run fairly low-end hardware (recycled RAM and such) and I have noticed that 64 bit tends to use much more RAM than 32 bit but I doubt that would increase the CPU temp.

Is this a laptop or a desktop?

I should have asked in my last post, please post the output of:

That's damn HOT!

And I see you only have about 150MB of RAM available out of 4GB so it's time to let things cool off and then try 32 bit to see if it's better!

But you didn't post the hardware info I requested :(

But that's hardware failure HOT!

Sorry, I'm an idiot. Working on two things. Ignore this part:

I'm a dummy, sorry :confused:

I'm not at all comfortable playing around in a laptop so I'm certainly uncomfortable recommending anyone else do so but it's possible that something (probably kernel related) is preventing the cooling fan(s) from running properly.

But, it is not safe to run at that temp!

No, he has 2042MB of RAM available. The RAM being used for disk cache will be made available to applications if required.
