Hi, and first of all, sorry if my English sounds like gibberish. It’s not my native language. I’m good at reading, but my writing has its hiccups here and there. 
Now, onto the actual topic. I have a beige Power Macintosh G3 desktop, Rev. A, with a PPC 7400 @ 400 MHz. The processor comes from a Power Macintosh G4 Yikes. The motherboard on that one is broken—just in case anyone’s wondering why I’m not just using that Power Macintosh G4. Unfortunately, the G4’s heatsink doesn’t fit because it’s way too tall for the compact Outtrigger case. So my first question is whether there’s a fan you can recommend, and if so, how you’d mount it. I’m thinking of the Noctua NF-A4x10 FLX running at 12 volts or even the NF-A4x20 FLX, but I’m not sure if they’ll actually fit or if they could be mounted vertically on the front of the heatsink.
Thanks.
