Aw Geez Louise, can ya believe it <smackin' forehead> ...? After umpteen hours of wailing and gnashing of teeth, from hair-pullin' frustration....
The "flakin' out" behavior of my G4 upgraded AIO seems to be resolved - and how it got fixed would be hilarious if I wasn't so chagrined at the "Doh!" quotient on this one.... When ya crack open yer 'pooter to replace a dying hard drive, might as well add some cooling muscle to the heatsink while yer in there, right? That's what I was thinking when I picked up a Pentium CPU Fan/Heatsink from Rat Shack. If it can keep an Intel processor from overheating, it oughtta work wonders on a G4. So when the oddball app crashes and system freezes began to reappear, and then to increase in frequency, I was pretty baffled. Checked all internal connections many times. Double-checked that I'd mounted the heatsink right. Rearranged the USB, FW, and Radeon cards while invoking Voodoo mojo. Restarted with chassis tray slid open, to visually verify the heatsink's fan was spinning. Applied a fresh dab of heatsink compound and remounted the heatsink. ETC....Things just kept getting worse; and MACh Speed Control reported temps climbing into the 64-68 Celsius range. G4 temp reporting is notoriously inaccurate, I know - but that's still quite a jump from the 48-56 range that was the norm before I changed heatsinks. So, one more time, I slid the chassis tray open, started up, and put my hand over the heatsink to see if I could detect any "airflow anomalies"...and felt nothing. What the...? The fan was pushing air down onto the heatsink, rather than wicking it away. Flipped the fan over, so I could feel steady airflow coming off the heatsink. Presto change-o! Temps have dropped a reported 20+ degrees C - and all seems stable and normal. Who'da thunk any reputable company would sell a heatsink/fan assembly that had been mis-assembled...? I know we're just talkin' about Rat Shack here, but Geez - it ain't rocket science...! It's a pretty embarrassing brain cramp for me, not "hand checking" the airflow right away....but all's well that ends well, I guess. Pax, --- Gene, a.k.a.
