Fan in Audio Research tube pre-amp

Do audio research pre-tube like LS26, LS27, Ref 3 and ref 5 all come with fans? If they do, is the fan noise noticeable?

Tube preamps typically do not run hot enough to require a fan. Tube amps, including ARC models like the Ref 110 do have a fan as do some of their solid state amps like the SD135 which I owned.

As an aside I noted a tube power amp by Synthesis required an "ultra Low Noise fan" using the entirely encased design shared by many ARC tubed power amps. I can't judge if it is a detriment or not because I have not actually heard an amp with a fan for any length of time. Intuitively it would seem like a bad idea especially if it doesn't have its own isolated circuit. Sort of like turning on a blender in miniature while watching TV (Old TVs anyway).

I can't think of any ARC Pre that has a fan? But I dont know them all. And the ARCDB is indeed a great site http://www.arcdb.ws/ TD
