Macintosh SE fan noise
Posted by: Punkyclown on 2018-06-21 10:50:44
Hi All, 
Can someone advise me on weather it's possible to replace the fan in the Mac SE for a quieter one.
That's the only thing about the SE that is annoying,  the fan noise.  The replacement hard drive I installed hardly 
makes a sound.  But the fan, Boy...
Thanks in advance, Brad Hansen

Yes, a noctua fan fits quite well and is very quiet. I used a NF-A6x25 FLX (60x60x25 computer case fan). It even had a connector to tap into the hdd power loom.

The SE had two fan variants: One that is a standard size computer fan and one that is very different. As long as your SE has a standard fan, it is as simple as undoing some screws and desoldering some wires from the analog board.

I tried replacing my fan a while ago with one of these: https://www.amazon.com/gp/product/B00006B8E7/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

It did not reduce noise very much and it is still quite loud; I would not recommend it. I think the problem is that the SE has no fan control and runs everything at 100% power. It might be possible to add a strong resistor or potentiometer in line with the fan to take some of the speed/noise down, but I have not investigated. I do know that Noctua fans are much higher quality and might still be quiet at 100% speed.

The noctua is definitely quiet on full speed. I got it because other fans were so loud.

These are SE fans. 

The second one is easier to replace.

If anyone has a cage fan they don't want, I'm really trying hard to look for one for my SE

Thanks in advance

Squirrel cage fans, are notorious for being noisy, but far more efficient than later units.

Had a pair at some point, that and the early Rodimes or Miniscribes Hard Drives and you are ready for heavy headaches.
