Two fans on the TT

Postby Moulinaie » Thu Dec 28, 2017 8:51 am

Hello,

Are the two fans of the TT useful?
I have changed the fan of the PSU, and much less noise is noted.
But... the second fan (behind the hard disk) is really noisy! Can I remove it without any problem?

The TT concerned is the old one with the metal shield.

Guillaume.

I would not remove them.

One fan cools the power supply, the other cools the hard disk. Which one you would like to let die because of heat?

I removed the hard disk for a CompactFlash adapter.
So, the second fan is maybe not needed.

But I'm not sure of what you say!
Looking at the metal shield cover, the hard drive zone is isolated from the second fan. This last seems to take air from under the shield to push it outside.

Hi,

No one for any experience?
Among the ones that own a TT with metal shield (and the daughter CPU board), do you all have two fans? Or just the one on the PSU ?

Thanks!

Guillaume.

Only the older TTs have the second fan, when you have no HDD in it so you can remove the second one. I habe ThunderStorm in my TT (2 Thunders) but my TT is in a Tower now (Hardware development reason) so only the PSU has a FAN

A tower chassis is completeley different. It has much more air volume inside which would need to heat up. It should have more gaps and holes for air circulation with the outside. Because of the height of the tower chassis there is also something a bit like a chimney effect inside the chassis which drives air circulation. And the metal chassis of the tower also cools down the air in the inside, a bit like a (n inefficent) heat exchanger.

Original TT chassis is much more closed and the plastics of the chassis behaves more like a temperature isolator. So for warm air it is much more difficult to get out without fans.

The reason you want to remove the fan(s) is that they produce noise. That is understandable. But there are also very noiseless fans which you can not hear normally. I recommend you to use Sunon maglev fans. They don't have ball/roller-bearings but magnetic leviatation system bearings. So these fans turn touchless in the bearings, that means the bearings are noiseless and undestroyable as there is no friction at all. Aditionally also the fan blades are very silent. I had one PC with such fans running allmost 10 years almost nonstop as mediacenter and TV recording system, after that the whole system was very bad but not these fans. Everywhere where I can I replace with Sunon maglev fans I do so and I am very satisfied.

Sunon Maglev fans ? Never heard of them. I should try that for my noisy CT60 Falcon.

You should read what i write, only the older TTs has 2 Fans because the Hard Discs getting Hot, but when he moves to a SD or CF Card he dont need a second fan. Its normal that a tower is much different, but my TT was original also only with one fan (in the PSU) so why should he need a second fan ? For what ?

YOU DONT NEED A SECOND FAN WHEN YOU USE NEWER HARDDISCS OR CF/SD

We have historical hardware. The cooler it stays, the longer it keeps.

I never had the second fan in my TT. It was running ASV as mailhub for like 15+ years 7x24 in the attic and didn't complain, not even in hot summers.

You always have arguments against silent fans.
