Update: I found a used TC BAM200 and will give it a try. My second option in case this doesn't work out is the Warwick Gnome. Thanks for all the suggestions!

Be advised that I myself purchased a Gnome less than 1 year ago.

Today I heard loud squealing sounds from the fan and further inspection revealed failure at the fan with squealing intermittent operation.

I ordered a new GK Mb200 because it has a great reputation for durability.

I used my Gnome lightly at home.

Double Bass Thread 'GK MB200 for DB: overcoming baked-in tone'

I'm starting to use this backend rig for DB (why? because it's what I have!), mainly for stage monitoring, but in small places, for the whole room:
  • Gallien-Krueger MB200
  • Gallien-Krueger Neo 112-ii
I think it sounds pretty good with bass guitar, but I haven't been happy with it for upright. It comes off as very harsh in the high end. I tried a lot of knob twisting and turned off the horn in the cab, but never was satisfied with the results.

I use a front-end rig (HPF/EQ/DI) that feeds FOH and mons when available, and I'd like whatever amp I plug into to sound the same as FOH...

I was surprised.

I think that I can replace the fan with no big problem.

It is a very nice little amp.

Although I only had it a few months I played thru it almost every day, a lot. But not loudly or in a demanding way. I never moved it around from place to place or abused it.

Checking into it I found that it had been a known issue with documented successful solutions using the little replacement fans readily available.

Do you know if the fan has to be from the OEM are another fan can be used ?

The original fan has the performance that the designer intended, and it will have specific safety certification too. The amp’s safety certification requires a specific fan that has the necessary IEC 62368 component safety certification too.

It was sort of counter intuitive but I got to the simple fan and it is easy to remove, and replace with a more reliable fan. I ordered the fan. Comes with adapters.

I think that is the only problem with the amp. I got to the repair fast, without using it a lot after the first signs of malfunctioning.

The stock fan looks new of course and surprisingly, despite the squealing, it was not dirty or clogged.

I prefer a fanless design but don’t mind an almost silent fan like these. The only problem I see with fans is dependability and breaking down. Otherwise I’m good with fans.

This fan seems to be fairly simple to replace but getting to it is odd and more complicated than it should be. It seems like a lot of the design factors are not aimed at players. Other objectives and priorities take place.

Nevertheless I like the little amp and will try to fix it and use it for now. I really like the sound and tone of the Gnome.

The accessibility of the fan to players is not part of any design intent as it’s not intended to be player serviceable (for a lot of reasons).

To a qualified service tech it not an issue.
