Fan noise on Thunderbolt display

I didn't even notice that the TB display has a built in fan, but I can feel the airflow and after half an our of usage the display itself and the air coming out don't feel warm. I have keyboard and gigabit ethernet attached to it. The first time I used the display it became quite warm, though I din't notice the fan (and I'm very sensitive to fan noise). In the meantime I applied the Thunderbolt Display Firmware Update. Maybe that caused some improvement.

The firmware update can be found here. It should also be installed when doing a 'Software Update'. During the update the screen goes dark for a few seconds.

I just unboxed my TD tonight and set it up. I have it connected to newest MBA i7, 256 GB

I also have a gigabit ethernet cable & an 800 firewire cable attached. The latter going to an external g-tech drive for Time Machine.

After the unit was on for about a half hour or so, I started hearing this rushing fan noise coming from the lower left side on the bottom where the metal is perforated (facing the front of the display). In addition to the noise, it is pumping out quite a bit of heat.

I am not doing anything processor (or graphics) intensive. A little email, web serving, etc. just kind of exploring what looks good in what size.

This is my first display only purchase. I also have 2009 24" iMac that I have never heard any noise from.

My question to the community is this: Is this normal? I didn't even realize there was a fan in this display. I could find no reference to this issue in the manual that ships with the unit.

Thanks, everyone.

Has fan noise continued?

Hi,

I had the same problem, it was like having a hot and noisy fan on my desk.

Fortunatly, the firmware update seems to have solved the problem.

(Most of the time, the fan was speeding during TM backups)

Thanks for the link to the update.

I have this fan noise issue from time ago, and I could not install the thunderbolt display firmware update 1.1 bescause there´s a message telling I don´t need this update on my Mountain Lion OS. I´ve checked through the utilities folder and can´t find any program which helps me. Is there any solution to this issue in my OS??

I have this fan (or static?) noise too, with MacBookPro early 2011 (Mavericks)

HELP Please!

At the end i think this issue was caused because the electrical tranformer was emitting this sound. I´m waiting for a replacement part and with it, i´ll try to fix this problem

I have this "static" noise emitting from the display. I have tried rebooting and unplugging... but no change. I tried the update to the firmware, but that was "not needed" (apparently my firmware was already up-to-date). The noise does not change with the volume control. Any other suggestions?
