Looking for a slim, quiet fan to put behind my Fisher 400

Same Amazon seller has a quieter AC fan for a few dollars more. The first one appears to be a 12V DC fan running on 5V. That won't move a lot of air, (doesn't need to) and will be very quiet. The 120 mm size moves considerably more air than smaller ones. There are thinner ones, but they may not stand up - you may have to attach it to something.
 
Yes, 30 dBa vs 47. There are a lot more choices in DC fans, but the AC one may be more convenient - the DC wall wart may not be ideal for a switched outlet. I use a pair of DC fans in my audio rack, connected to a "universal" DC adapter - even 12V fans on 4.5V make more noise than I like.
 
I always see people write "Remember to blow the wind away from the tubes not straight towards the tubes." Can someone explain?
 
Check out computer parts sites as well. If you really need thin, you should be able to find a thin whisper fan.
 
Funny,
I've been using a larger fan for years and have been directing the air towards the tubes, venting the air through the top. The Fisher has stayed cool that way.

I have been working on fan and chilled water cooled electronics since 1984. Every fan cooled unit has the fan sucking air out of the cabinet. People supposedly smarter than me designed it that way. :rolleyes:

It does make sense to suck the air out because if you do it the other way it messes up the air flow from the tube vents that are usually near the power tubes on the chassis.

Cabinet design is rather integral to the whole thing though. Usually there is ducting or baffles or openings or all that at specific locations to control the airflow path, yes?

That's a fair bit different, I'd think, than setting a fan alongside something, just free air, and hoping it pulls air around where you want it to.

Agreed, but I have an old cabinet fan “sucking” here (middle box with Maggie). According to my IR gun it runs the same temp blowing or sucking so I have it sucking. I need to get a current pic with the fan.

Edit: and we are only talking a few degrees cooler, not doing much for the amp more for moving the hot air away from the front on my space.
