I've checked the inside of this laptop.

The fan is easy to change if you ever  find a replacement, but the problem is not in it, but the bios controlling it.

I removed the heat pipe as well and noticed "nothing special". Like always, too much heat compound was used so I removed them all and put a little silicon paste.

Noticed also huge caps between "heatsinks" and  GPU and north bridge, which was tried to fill with dried and hardened heat paste - though nothing special in this.

 I removed the stuff and filled the caps with small aluminium blocks.

Also the size of that copper cooler part is perhaps undersized in case that I cools down some other chips too, not a CPU alone, which leads to inevitable fan usage. I'm not claiming that active cooling is bad but it could be constant with less noise.

Wow, good for you!

At least Lenovo now know what the solution to this design fault is.  I hope technicians have taken notes and are modifying all G550s appropriately.  Or maybe they'll just have a laugh amongst themselves, which is obviously what the rest of the company is doing.

Do you mean there is a solution idea from lenovo ? just a few days before  lenovo denies that the problem even exists !! I hope there will be a product revall  ! 

[#3]

Could anybody tell me what to do with this crazy fan? I think it would help if I'll install there
variable resistor or something. It very disappointing.

What telling company about this problem or they dont get it yet? Million people around the world f**cked up by this problem and company woudnt say any words? Please who knows anything about Lenovos thoughts about this problem with G550 fan, write it there... thanks

No, Sontakasa seems to have come up with his own solution.  No-one from Lenovo has bothered to  respond.

Just want to show that im also interrested in the solution.

[#6]

I am interested, too.

Is it possible to solve the problem with an bios update?

[#7]

Lenovo i am waiting. This fan on/off really iritates and makes me nervouse.

This is my first lenovo laptop and because of the support(and this problem) it looks like it's going to be my last if nothing soon happens.

My girlfriend has a lenovo g550 (the model without the nvidia GPU) and her laptop works fine (no fan on/off when the cpu is at 2-3%)

The reseller told me everything is fine wait for an bios update but i use my old laptop because of the irritating sound he won't even "listen" to the problem.

The problem is from  september and still no bios in sight.

That's interesting. You are right, the heat problem is coming from the Nvidia chip.

If you open the laptop you will see that the instead of a proper heatsink it has a long  thin strip of copper going over the CPU and GPU together.

The nvidia 210m needs much much better cooling, so it heats up the entire mini heatsink in minutes and the heat is transferred to the cpu which otherwise would have been fine. Genius design from Lenovo, the legendary chinese quality in action.

Must be the first company that managed to efficiently cook the cpu with the heat coming from the graphic card, all to save 100 grams of copper.

Its not the point of problem! Big problem is fan. Lenovo G550 can't adjust fan speed and it spin like crazy. Fan spins on maximum or at minimum speed, without any other rpm.

I had "funny" experience here in Sweden. I contacted the shop I bought it from. They refused to refund and instead I was given Lenovo Sweden customer support number. When I called there, I was told that these laptops have their own support line and was given number. Very polite people are working at Lenovo. When I dialed number I was given, guess what....it is not working and when I called back to Lenovo, they just were sorry that they can't help me. I love this! They really do not care about their customers. I think this problem will have to wait long time for solution, if it ever happens!
