Title: Amiga 3000 PS Replacement Fan
Post by: Kernel on November 16, 2014, 05:16:22 AM: Looking for a replacement fan for my A3K... the standard one is way too loud. character yes, but I'd prefer it to be more on the silent side.

Does anyone know of a direct replacement i.e. what size or more specifically a model number of a known replacement would be great.

One with LED's could be cool too but I could live without that.

Thanks!

I can't remember the size, but just measure in with a metric ruler.

It's 80 x 80 mm

A) Noctua is an excellent fan.
B) A noise <21 dB is D_amn quiet
C) 25mm width is about an inch (2.54 Cm to an inch), which if fine if it fits.

So, sounds like a good choice/recommendation.

ARCTIC F8 TC -80mm.

Also, I haven't done testing with the case on yet (hopefully I'll get the IDE terminator today and will be able to put the lid back on, at which case I'm going to use my temperature prober to see how hot everything gets.)

Also, if you have an older CD-Rom drive, the one that I got with my A4000D was loud as hell, replacing that with my old SATA Plextor drive reduced noise tremendously. Though oddly with the two IDE->SATA bridges I tested, neither would work with the onboard IDE, but did work with my FastATA 4000.

Which tends to run hotter, the 4000 or the 3000?

It's a Nexus SP802512H-03.

Post by: QuikSanz on January 15, 2015, 03:56:01 AM: mechy is on it. High cfm is important because that air also cools the expansion cards, only fan in there.
