Finally took the time today (all of ten minutes) to silence my MDD G4 PowerMac. Should have done that years ago!
Everybody’s favourite company (yeah, Apple) released magnificent G4 PowerMacs at the time. I have a dual 1.25 and it still runs like a champ! Yes, that includes Tiger and all the latest software available. Doesn’t break a sweat.
But the noise…. yes the noise. It’s bad. The fans are just too damn cheap and, well, noisy!
I believe I already have the upgraded power supply (it’s rated at 360W) but the mac still was just too noisy. It’s like a vacuum cleaner. There’s a kit available to silence a G4 but it’s a whopping 250 euros! Well that’s about the resale value of the entire mac, so no deal.
Just for fun, today I disassembled the mac’s power supply, took out the fans and brought them to my friendly neighbourhood electronics shoppe. Expecting nothing, the guy behind the counter grabbed two replacements without blinking. Twenty euros and a bit of screwing later….
… bliss …
What a difference.
Anyone reading: if you have a loud MDD G4 PowerMac, you really should know that it’s easy to reduce the noise. Every computer/electronics store has these fans. They’re 10 euros a piece.
Next up is the main case fan, also noisy but much less so.
I’ll keep y’all posted but for now I am extremely happy!
There’s more tricks on this page that I am considering. But not after I have replaced the 12×12 cm case fan first.
hi my name is J
i just purchased a G4 and im not happy with the fan noise. could you tell me in more detail how you silenced yours. i.e. what make were the fans you bought, how you installed them. any pictures would be helpful. im not a tech head & would appreciate your advice, my email is j.valentino@mac.com
many thanks. J
1. open your mac case
2. remove the power supply unit (instructions on the links on this page)
3. open the power supply
4. remove the two fans
5. bring these fans to any computer supplies/electronics store and get new ones. preferably the most silent ones they have.
reverse all steps and your g4 will be a whole lot quieter. the fans in the power supply are the most noisy of them all.
