Reduce Loud Rattling sony vaio CS fan noise

Update: 3 months since my post on reducing the fan noise. The noise seems to reappear. I took apart my vaio CS again to peep inside and try to figure out what exactly is the problem. I found that there is a lot of wobble when the fan rotates which makes the blades to brush the edges. So i came up with this.
Take a smooth surfaced plastic washer and stick it to the base of the center rod in the fans, like this in the photo. Look at the arrows to see how the washer is stuck to the base of the fan. After this put everything back as before. Now the fan noise is very minimal as the wobbling reduces to a great extent and the fan runs smoothly. For full article look below.

                                                                 

Hi it has been nearly 10 months since i started using vaio CS17G, it is an excellent laptop running vista without problems thus far. But since yesterday i started getting a strange loud fan noise all of a sudden.
I could follow the temp readings and the noise came on as soon as the temp was nearing 50C.
After googling for a while i learnt that this is a common problem with the sony laptops and was attributed to the faulty fans manufactured in china which were used by sony for their laptops.
I could go for repairs from sony under warranty, but for many people the problem returned after the repairs.
Since i had also partitioned the hard disk and installed ubuntu, i was not sure of warranty.
So i decided i will fix this on my own.
So these are the steps to reach the fan and fix the problem.

1. Disconnect power cable after shutdown and remove battery.

Lalbagh Flower show 2010

It is the time for the famous lalbagh flower show again. I was lucky to have visited it this year to witness the beautiful display of flowers. The flower formations inside the glass house were splendid especially the orchids, orchids with a wide range of colours. Here i present some of the photographs from the same.

Stop freezes gutsy linux

Since i updated to gutsy i was experiencing freezes whenever the power status changed, for example when i switched from AC power to battery and vise versa.
I was not even able to login after installing gutsy and it would freeze at GDM level, i remember i had to prevent powernowd from loading at boot. This made me possible to login.
I would also get freezes whenever there was intense CPU use for a period of say 10 secs or more. This would happen for example when a web page in being loaded which has got some Java applications.
I was fiddling a bit with the system last week, i wondered any one of the updates since gutsy release has managed to resolve this issue. So i opened system->Administration->services, enabled powernowd. That was it, system had an instant freeze and i had to do cold reboot.

But now i started facing the same old problem of reaching till GDM and the system freezes.
I tried to boot into recovery mode and did
/etc/init.d/powernowd stop
that would allow me to select GDM and login normally. But once i did reboot i would experience the same freeze at Gdm, which is understandable since stoping powernowd worked only for that session.
so i was left with the only option of getting rid of powernowd.
I was back in recovery mode and did a
apt-get remove powernowd
That did the trick, i can login without any problem and to my surprise i am no longer experiencing the freezes i use to get with power status change and with intense CPU use.
In effect, i lost CPU frequency scaling and gained in the sense that it stopped the freezes on the laptop.
I am not sure of the implications of running the CPU at full scale all the time but i am more than happy of not seeing any more freezes and having to do a hard reboot.
