the G5 that roared was Re: Steve Jobs -2011

I used a dual G5 machine for an instructional course once upon a time. The OS was Yellow Dog Linux, and it had fallen behind the hardware in that Apple had changed hardware in the thermal control and YDL didn't recognize its reported version number. The thing was as loud as an old Hoover. I found and fixed the offending code and it purred quietly in the corner. And even with a dozen students running instances of a compute-intensive simulation, it remained cool and quiet. -- Ian ________________________________________ From: cctalk-bounces at classiccmp.org [cctalk-bounces at classiccmp.org] On Behalf Of Cameron Kaiser [spectre at floodgap.com] Sent: Sunday, October 09, 2011 7:44 AM To: cctalk at classiccmp.org Subject: the G5 that roared was Re: Steve Jobs -2011 When the quad G5 (I don't know what G5 you own, this is the liquid-cooled one) is idle, it is reasonably quiet. In a room with no other computers you will hear it and it is about the same volume as my HEPA filter on low. In my old apartment, at idle, it was not louder than anything else. When I'm building stuff (it is the "buildbot" for TenFourFox) and ramp up the CPU to highest power, then it roars. A nice side benefit is I don't need a space heater in that room when I'm waiting for rebuilds ;) I can understand why Apple didn't want the G5 in a laptop, and even I have reservations about its design relative to the G4, but it was a pretty hot (heheh) Mac for the time and it still performs pretty well, six years later. I don't have any plans to retire it or buy an Intel Mac. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Premature optimization is the root of all evil. -- Donald Knuth ------------
