CTS-600 and CTS-1200 are class AB.
The others are class D. That is probably why they have different specs, and probably different sound.

Works just fine. Both connectors are the same.
The power supply are not the same on the 120v and 220v units. And they are not easy to modify.

I have now done this fan-mod to one of my CTs-1200. Great success.
Thanks for the info previous in this thread sebackman.
Have ordred an Crown DCI that probably also need new fans, org is 24v 60x60mm... I've read that some have used 12v Noctua and "transformers" to make them work With 24v, is this the best way or are there any quiet 24v 60x60 that could work instead?
From the Pictures it looks like a single 60x60mm fan in the DCI's
Most other 2HE Crown's are dual 80x80mm fans. Are you sure they are 24V?
If dual fans you can just connect them in series = 24V. Job done.
If not dual fans, check for Pabst fans, they probably have silent 24V 60x60mm. Expensive but good. Check for clearence as the silent fans often are deeper.
I would avoid using resistors and/or reducers because if they fail the fun stops quickly.
Kind regards

Hi bubbleboy76,
Glad it worked out satisfactory. It's a big difference and I have not had any problem with mine. Even the CTS 8200 can be silenced by using 3x60mm and one 80mm fan.
Kind regards

Now all 4 of my Crown CTs-1200 are silent. Very nice.
Hi, I have a CTs600 that’s need a fan mod but to run 12v in series must be a risk in my mind. All you who have applied this solution have any of you got in to trouble with CTs600/1200? And what can happen to the amp by this solution, for example if the fan(s) would overload and burn?
Was searching general solution for running 12v fan on 24v source and found these DC-DC step down converters. Seams like a more suitable solution to the problem. Add one of these to one of the output on the amp and connect two fans I parallel:

Or this cars decive

I would like to try this model on my CTS 3000
Someone has already tried this model ?
a little less powerful but for the house
much less noisy
