Hi everyone!
If you have recently bought a new VGN-CS11 series notebook, I'd ask that you take a moment to read this post.
Since I unboxed the new notebook, I have been experiencing strange noises from the fan unit evey time it operates. Before, it used to be simply that every time the fan stopped working, it made a soft "growl" noise (probably due to some internal vibration) for a mere second or two. Recently, however, it has also begun to make a strange, barely audible "clicking sound" as the fan starts up and operates, accompanied by the "growl" at the end, like before. At first, I was led to believe that it was just the normal operating noise that the fan made (although quite annoying!), but due to these recent developments, I am more and more convinced that this is some problem or malfunction that perhaps, will only get worse with time.
Other CS11 users have already posted in the thread "Problem with fan!!" that they also experience this problem, and, from what I've been able to gather, it does not seem like an isolated problem... but this is what we need to confirm.
That is the purpose of this thread.
I would like to ask and encourage all CS11 users to post in this thread if they also experience the same "problem" with the fan (abnormal noises that are clearly distinguishable from normal operation) or anything fan-related, especially if you have experienced them since you bought the notebook and haven't done anything that could "provoke" them (like dropping the notebook or hitting it in some way, blocking the ventilation vents, etc...). This is to have a general scope that this is not an isolated problem that is only happening to a few, and that way, perhaps Sony will take an interest and take the necessary measures to correct this problem if this, in fact, turns out to be a generalised problem.
I have already created a new case with e-Support regarding this issue. Note that these are brand new laptops that have been out on sale for barely a month, and now would be a good time to correct any problems that may arise. If this turns out to be a common problem for most CS11 users, then we should all contact Vaio-Link or e-Support and report the problem, so that Sony will take this problem into consideration if enough people have it.
Remember: the sooner, the better! 
Also, perhaps it would also be of interest that those CS11 users that DON'T experience this problem also post in this thread, to see how many DO and how many DON'T... it may be interesting to also know.
Ok... without taking any more of your time, I leave this thread to fellow CS11 users and to anyone that might be able to lend a helping hand. Thanks!!!

Dear thalamus,
Is there a way for me to know which model of fan do I have on my CS? after 3 repairs it still works well but i'm always afraid it might break again...the sound that was normal untill two days ago now sounds strange to me.
ciao coral
I sent my vaio for repair again
this time the LCD had some problems....
So they told me they will replace it....
3times i sent for replace the fan
now the lcd ,crazy
It started made some line of pixel with different colors then at startup the screen was like moving up down.
Im very bored of this notebook, i just think i wasted my money... 900€
I should ask the money back but i know for this things you need ask a lawyer or they will do nothing just repair it again and send you back till it will broke again.
Someone get the money back?
@coral
io ho comprato il notebook da mediaworld con la garanzia di 4 anni ma leggendo bene i moduli non credo sia facilissimo farsi rimborsare queste riparazioni una volta terminata la garanzia , vedo che tu sei di udine beh io sono di gorizia siam vicini
