Macintosh SE Fan noise

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

There are LOTS of fans now that will work much quiter than older Deltas and such, but you will want to #1. get the specs of the fan/s you are replacing and make sure the replacments move a comparable amount of air and #2. possibly re-apply thermal paste to your CPU if it is running hot after.
Phobya Grease https://www.amazon.com/Phobya-NanoGrease-Extreme-Performance-Compound/dp... consistently comes in 5-7 degrees cooler than older Arctic Silver.

I don't recall having seen any sort of heat sink on anything with a 680x0 series processor. Maybe on some of the faster 68040s, or maybe a IIfx? It's been too long ago to recall. But a heat sink on an SE? Never.

Yes, its the case fan, Brad was looking for. Wink
Can´t harm mentioning good thermal grease, though its superfluous here.

"reapply thermal paste to CPU..."
I've been searching for a low cost household product to use instead of gourmet brandname paste, there must be some things that are good enough.

My MDD started crashing a lot, and I noticed I could make it stop crashing by downclocking the CPU from 1.583GHz on 167MHz bus, to 1.425GHz on 150MHz bus, I have a toggle switch for this. I had been using white lithium grease for CPU paste but it eventually evaporates away every few years. It caused crashes like Kernel Panics, not actual overheating.
Now I just put on a little "Vaseline" under the heatsink and she's working again at 1.583 GHz great so far...

[Edit: fast fwd a month, & the common "Vaseline" is working very great as a chip paste! and on a system that's highly sensitive to paste quality]

Thanks for that info and feedback, SkyCapt.

Vaseline certainly would make a "low cost" alternative to thermal paste Smile

There is a thread over at 68kmla recommending this one, if you can live with a brown fan:
