Undervolting & reducing fan noise Sony Vaio TX5

Hi, my new sony vaio tx5xn cooler is working all the time and it's really annoyed me. Maybe anyone know how to reduce sound or maybe there is any way to exchange the cooler for a quiet one? I often move with my laptop so a cooling base is not very suitable for me. Is Undervolting working with this laptop? Processor Intel Core Solo CPU U1500 1.33GHz.

 

Try undervolting with RMClock. I don't know if it will work but you'll find out easy enough.

 

Can you use Speedfan or a similar program to turn down the fan a bit?

Make sure the temperatures are alright afterwards though.

EDIT: Also, if it's having to work, really, really hard, there may be something wrong with temperatures so just download CoreTemp and check them, just to be sure you're OK.

 

Speed fan rarely works on a notebook and does not work on Sony Vaios in general.

 

ok I already run RMclock and after 10 min. test I had 59C now I'm doing 45 min. test and temp. is 64C. Do anyone understand what is wrong with this? Maybe first test was not done successfully. I can't understand also flipfire in point 5) ***Testing Stability*** where he says - "If it doesn’t crash when the stability test is done then you can go lower. I suggest lowering by .025v at a time till it BSOD or gives a warning error." What does he mean "go lower", what I actually should do? Ok and than if I finally will know how to "go lower" should I do the test again after each .025v?

 

You don't have to test every .025v

Go lower means lower the voltage.

To give you an idea, my normal voltage is 1.34V and now I run stable at 0.972V. My fan never comes on.

So what is the normal voltage of your CPU and untill what voltage have you lowered it?

On the 'monitoring' page of RMClock you can see your current voltage.

 

ok it means that in RMclock in profile selection window I have 5 boxes from 0 (0.9375V) till 4 (0.9750V) so I should untick 4 boxes and leave only first box with 0.9375v?

 

You only need to work with the active multiplier in the current profile.

You may need to understand better what you are doing. The undervolting guide is here. Read part 2,3,4: http://forum.notebookreview.com/showthread.php?t=235824 You don't need to read the rest.

I'll move your thread to the Hardware section as it is more appropriate there.

 

ok after several tests I managed undervolted all multipliers (actually not much but only this was possible, from 0.9750V till 0.9375V) and under Orthos CPU loader test temp. fall down from 70C till 64C but I mostly use internet and nothing more so my CPU doesn't have many job and in this point there is no difference in temp. (I checked surfing inter. with RMclock and without). As wrote K-TRON ULV processors are not very suitable for undervolting.

I don't think cleaning fun will help because I bought this laptop new and I also read some tests so people claim that this fun is working all the time and this is normal thing in this model.

Is there any other method to make CPU cooler? Maybe Disable/shut off all background processes will help a bit?

 

What I did more.

I disabled 17 out of 23 programs form startup in msconfig. I visited a useful page - (netsquirrel.com/msconfig/msconfig_vista.htm) - and checked with long list (sysinfo.org/startuplist.php?filter=msascui) which programs are really necessary.

Now if I don't use my CPU much, temp doesn't go over 50C and fun is not working ( it never happened before!)

 

A clean install is another way to have even fewer background processes running.

How many processes do you have running after you've booted? (ctrl-alt-del)

I run my XP SP3 with 20 background processes.

Another way to avoid fan noise is to block all flash content on websites. (Flashblock)

 

I have 69 processes running. How to reduce them?

 

69 is a lot for XP.

The best way to reduce them is to perform a clean install. You would need a XP cd. Drivers can be downloaded on Sony's support pages. Maybe you can use one of the clean install guides on the Sony forum. I don't know if there is a special one for TX but it could be possible.

Another way would be to clean up your system using tools like Ccleaner limiting startup processes and uninstalling software you don't use.

 

Actually I have windows vista business and I think this may cause so many processes. At the and I might swap it into XP ( vista business allows to do that). I will try as you suggest tool like Ccleaner or something like that.

 

Ok yeah 69 processes in Vista is not too bad.

A clean install XP is better for reducing fan noise.
