So I recently acquired a 2.3DC G5 which at first POSTed to memory errors - as it turns out, the previous owner put incompatible memory in the machine. So yay, €30 for a complete machine, original HDDs and all.
The machine doesn't run too hot in idle, but it goes up quickly when I load up the CPU. It's also pretty noisy in general, so I think it's due for a repaste and thermal calibration. I have ASD 2.6.3 here handy after my Quad adventures. Given that the U3 is known to run hot as well, I want to inspect and clean the entire machine, being extra vigilant when looking for bulging caps. Logic board out and all. An FX 4500 (proper PowerPC version) will be revised as well.
As far as I know, there are no thermal pads on a 2.3DC, just thermal paste. The FX 4500 does use thermal pads for the memory and if memory serves me right, they're 2mm thick. Can anyone confirm that?
In doing a full overhaul, I want to repaste the CPU and the U3. Not sure about the two heatsinks inbetween the RAM banks, I may keep them there.
I've read https://forums.macrumors.com/threads/power-mac-g5-dust-out-and-thermal-paste-re-do.2097720/ (thanks AphoticD!) and done some Googling myself as to what would be the best solution for thermal compound. I see two options: the easy one is getting a tube of high quality thermal paste like Noctua's NT-H2 or Thermal Grizzly Duronaut (source) and the hard one is getting something like Honeywell PTM7950.
I'm not sure which of the two I would take. PTM7950 seems to be the be-all-end-all for direct die cooling, but it's pretty difficult to work with and it's not that well available here (and I don't really trust the AliExpress prices). Thermal paste is way more convenient, but it may perform less than the PTM stuff would. Regarding the thermal pads, I was think some Gelid stuff to do the trick.
Is the PTM7950 stuff really the way to go, or is that overkill? Reaching U3 for a repaste is a pain
And a side question: I'm trying to get 1920x1200 out of the FX 4500 (converted to HDMI, no DVI displays available...), but it either shows me 1920x1080 (which works) or 1920x1440 (which is garbled). 1920x1200 is not in the list in either Leopard or Tiger. Any tips? It's a 2560x1440 panel.
