    Just purchased a Z830 and I have the same problem - really awful noise from the fan.
    No process uses the CPU: look:


    top - 19:06:02 up 6 min, 1 user, load average: 0.15, 0.10, 0.05
    Tasks: 158 total, 1 running, 157 sleeping, 0 stopped, 0 zombie
    Cpu(s): 0.8%us, 0.6%sy, 0.0%ni, 98.6%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
    Mem: 4017472k total, 913652k used, 3103820k free, 41972k buffers
    Swap: 4090876k total, 0k used, 4090876k free, 533068k cached

    so there is a different problem somewhere in the controller of the fan. I also changed BIOS settings with no benefit.
    In another forum Toshiba guys say there is noise, but there is also on other PC's, which is quite an embarassing answer.

    Any hint, besides removing the fan?
    thanks!

    Hello, don't bother with bios update... it is a case problem. And especially a "pipe" design problem. The cooler itself is very very quiet when is out of the case. You can use a resistance on the red wire. Probably will void the warranty. Anyway I have a quiet ultrabook now.

    What do you mean, in practice, by "You can use a resistance on the red wire"? What did you do?

    Let me explain:
    Probably every noctua fan comes bundled with two adapters reducing the incoming voltage to 7V (L.N.A. Low Noise Red Adapter) and 5V (U.L.N.A. Ultra Low Noise Black Adapter). See the image here:
    http://www.xbitlabs.com/articles/coolers/display/fan-roundup_3.html
    I just cut the wire with the resistance from the Low Noise Red Adapter and use it. Z830 cooler have 4 wires: red, yellow, black and blue I think. Cut the red wire and use the wire with the adapter. This adapter is in fact a resistance (which probably can be found in stores - unfortunately I don't know the characteristics for it)

    After this operation, the fan noise is imperceptible. Anyway, if you put your ear on the back of the notebook you'll be able to hear a slight irritating buzzing sound.
    The fan itself is quiet. When the fan is on a table which block the air entering from below it will be more noisier (can make about twice as much noise). Till now, noise means just air flow.
    But, when the fan is inside the case, because of the really bad design of the copper pipe and "wings" - wings that cool the pipe, the air running out through the wings will make the BUZZ, very irritating and frustrating.
    Till now I use a Dell Latitude 13 with ULV processor + software able to lower the rpm. I preffer passive cooling :)

    Even now, as I am typing in a dead silence environment, I can still hear a buzz from 20-30 cm away. But I have to push my ears hard to hear this!

    I'm wondering if toshiba will do something for this....

    Hi there,

    I bought a Z830 and returned it because of this inacceptable fan noise.
    I also wrote serveral emails to the support team telling them, that they need to do something about it. But instead of addressing the problem they just denied that there is an issue with the fan noise, although I sent them another email with a lot of links to online critiques, forums and videos.

    The fact that they seem to simply ignore it makes me never consider a Toshiba product again. The Z830 would have been the perfect ultrabook for me and some members of my family... However, this way, Toshiba lost 4 customers.
    Today, lots of manufactures forget or ignore the impact support services have - they sell their products and that's it for them. Same story with Android Smartphones and the update support.

    However, if Toshiba decide to solve this issue - it is their fail - I would eventually buy one again.

    Same for me, bought a Z830-10J and the fan is just unbearable.

    I began to look at the comments on amazon.de, and most users report the same.

    I ve paid nearly a 1000 EUR for that and I fly to Africa in 2 days, with no possibility to return the laptop...
    ANY HELP IS WELCOME !!!!

    Hi BM

    Sorry but I cannot say more than other forum members. What I can say is that maybe Toshiba will offer some BIOS update soon that will fix this cooling fan issue.

    If Im remembering well in the past Toshiba has done the same for few notebook models.
    From time to time check Toshiba download page to see if new BIOS version is available.

    Good luck.

    Hi Pedro,

    do you really believe they will offer a BIOS update althought the email support team is still denying that there is a problem?

    I mean, when they say, we see no problem, I highly doubt that they will look into this. Why should they?

    Guys, a bios update will not solve your fan noise problem.
    It is not the cooler that have a problem, it is the case of the notebook. Check my posts where I'm explaining this.

    I have to add some of the problems I encountered after operating inside z830 ultrabook:

    1. Reducing the speed of the cooler bring me silence. Also bring me annoying "cooling fault" messages. I uninstall some of the toshiba monitoring tools and now is ok.

    2. Reducing the cooler speed will reduce dramaticaly the whole computer speed (cpu, video, ram and probably the sdd - which by the way - is sata 2 and very slow comparing with asus zenbook). I solved this by clicking the "Always High" option inside bios - dynammic CPU frequency mode!

    3. Radomly putting the 13+1 scr ews in place on the back of the notebook will bring you another annoying issue: the front left part of the notebook will be 1-2 mm rised - when the lid is up more than 90 degrees. I mean you can insert a **** of paper under the left side...This is annoying when typing. When the lid is closed - the back right side will be rised.

    The solution will be to find the proper scheme of putting the screws back.
    There should be a diagram about this. (I have this diagram for the last 4 new Satellite Pro R850-122 laptops that I bought - every single one of them had this issue. And because of the laptop move when typing, also the hdd inside entered in protection mode.

    This is not the case with Z830 SSD)

    I just bought one as well, and the fan noise makes it pretty much unusable. It wouldn't be so bad if the BIOS would not run the fan when it isn't needed, but the constant buzz / whine sound in a quiet room is really annoying. I think my laptop is going back to the store.
