Crown CTs Fan Mod

[JeffW]

Just a guess, I have no experience with these amps, but I imagine in a normal home stereo application that a couple of fans would be plenty as long as they are for general enclosure ventilation and not actively cooling a critical part.

Thanks. That would be my guess too. As long as it's technically possible to only use two of the fans.

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.

I actually think the 4200 and 8200 are AB as well. I think it's the 2-channel CTS 2000 and above which are AB.

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:

So its time to place order for the fan modd. Will this work for my CTs600?

I'm considering to buy a Crown CTS 8200. They can be found on the cheap on ebay these days. Has anybody tried modding the fans on those? It seems to me to be a bit more complex than on the other models, since it's four fans (one 80 mm and three 60 mm, according to folks here).

If you don't know it, CTS amp are either 110 or 220V and most CTS on ebay are 110V only.

My advice: Don't... The CTs3000 is Class-I which have a high idle-draw and need proper ventilation. I crashed a CTs2000 by using too weak fans.

[spicer]

thank you for your comment

[baldrick]

Nor CTS related but have anyone sucsfull replaced fan in iTech??

[Jonas_h]

I have never heard about someone doing it. Fan monitoring in itech is part of the built in error reporting and monitoring, so changing a parameter makes it shut down (is what I have heard - not tried)

[baldrick]

It’s the same I’ve read... too bad If there is no solution, I’ve replaced the fans in My DCI amps and If works great but I would love to also quiet the iTech

How are the fans working for you? I have the Crown 4 | 1250N but haven’t read about anyone proposing a solution for it.
