Can I get rid of fan?

[v8powerage]

I've got this old mac with 400Mhz https://en.wikipedia.org/wiki/Power_Mac_G4 and it has got very noisy fan, I'm not even doing anything on it, just listening to itunes but it's so loud that I have to turn volume up to hear the music, could I just get rid of that fan? I used to have an imac without any fan it was also 400Mhz

Everything inside will overheat and likely be damaged if you remove the fan.

Why not just replace the fan? I don't know if it will all over heat, but there is a possibility of it without proper airflow. That being said, you should be able to get a fan on NewEgg for fairly cheap and swap it out.

An iMac G3 and a Power Mac G4 running at 400 mhz are very, very, very different machines using different processors. G3s ran very cool and G4s ran very hot.

In short: No don't remove the fan. Your CPU will burn up.

This fan is massive

there's good sized radiator on the processor so I was thinking if I left it open perhaps?

It might, but with a G4 I wouldn't risk it. I'd just order a replacement.

what would be the replacement for this fan, some more quiet version?

I'm guessing the original fan is damaged, which is why it's so loud. The PowerPC forum here might know more. [Mod note: Thread moved]

The Power Mac G4 Cube runs a 450 or 500 MHz G4 fanless without overheating, but it has a massive heatsink inside and the case is optimized for convection cooling. I wouldn't try it in a G4 tower.

Any PowerMac G4 will use a standard PC issue 120mm fan for the case fan.

The PSU fan is 80mm (again, standard PC issue) and the intake fan on the Quicksilver G4 is 60mm (standard issue).

Nothing special about the fans. Find one of the right size you need with the highest DFM you can. Most modern ones are quiet, despite being high DFM.

In my QS I use a Cooler Master JetFlo, bGears bBlaster and Antec. All quiet fans, but with DFM scores that are considerably more than the stock fans they replaced.

You can refer to the cracked fan in my Quicksilver which was incredibly loud. I resolved the issue with a third party replacement.
