Did anyone ever buy an amp and find the fan too noisy.

    I bought a Hiwatt B150 combo because I was having bad problems with my rig. This Hiwatt sounds nice, looks great but the fan is too noisy. Well it was dirt cheap so I can live with it. Anyhow, when I heard the fan I suddenly remembered the exact same fault on a Laney amp I'd owned several years earlier. I kicked myself for not remembering that fan and to check before buying. Although I don't know how you find out over the internet if the fan is too loud. Has anyone else experienced this problem?

    It was common years ago, not so common today

    Fan quality is not a constant. Some have cheap bearings that will result in more noise than other models. There may also be cost cutting in mounting ie they're rigidly mounted to solid surfaces which transmit the vibrations.

    You could try a quality brand name fan and make sure it's on rubber vibration isolating mounts. Also worth noting that a larger fan will work more effectively than a smaller one for a given RPM, though I'm assuming you can't change that. I would hope they put the largest fan that can fit already.

    Also, does it have any speed control? As in, it gets faster when the amp gets hotter?

    Depends on your definition of 'too loud'.

    For pretty much any application other than micing the speaker in the studio it should never be audible over the sound of your bass through the amp.

    Many complained about the early Mesa Walkabout fans. I never thought they were all that loud though, and I still own one.

    Not going to tell you how I know this but some people get really upset if you mention the fan noise of their favorite amp.

    The Peavey MiniMax has a louder than usual fan in both V1 and V2 models . However if there is any noise at all in the room you can not really hear it. But it does sound something like a Humidifier running or something just above ambient room noise. So it would be too loud for recording a cab with a mic but for any other use it is fine.

    I have a Vietnam built Ampeg SVT6pro with a fan that gets very loud when it fully kicks in (it's rpm staged based on thermal load).
    Is it loud ... yes, is it too loud to use the amp for live work ? ... heck no :laugh:

    I have a gen2 Walkabout. I did do the fan mod on it, but the original fan, while audible if you were right on top of the amp, was not unusabe even in a studio/recording situation.

    Yep, mine does and I hate that when recording mixed acoustic / electric live. Love the amp, need to replace that fan....

    Older GK MB Fusion 800 made quite a whir so I let it go. Quilter BB800 also makes a whir as well as adding some hiss to the signal, but not too bad for a live setting.

    +1 there. I was about to say the exact same thing. I got one of the newly designed 2019 MiniMax amps. I love the way it looks and the way it sounds. Yeah, the fan is noisy, but for my purposes I can live with it. I'll take a noisy fan over a smoking overheated amp.

    1st amp I ever owned that had a fan was a Traynor YBA-3 with a single 8x10 cab. Fan wasn't too loud but the amp would take a dump about once a week. It spent more time in the shop than on the stage.

    I've been meaning to post a thread about this. Idk what generation my Walkabout is other than that it was made no later than '06. Silverface, one input jack with passive/active switch, black non-metallic cab corners, 12" speaker with a mesh dome, fan runs non-stop and is in good order but does run rather noisy when not at band volume.

    So is the fan supposed to run non-stop or not?:)

    Sorry for the hijack.

    It did?
    Were you gigging with it or only using it at home?
    I have never noticed the fan on mine:thumbsdown:

    Thanks AG! I saw your post in another thread yesterday about contacting Mesa with my serial # regarding updates and such. Never thought of doing that so ty.

    So now I'm curious. What's the fan mod then?
