Hey everyone, I'm somewhat new to the forums and would appreciate your expertise in things I know very little about. I have a dual 500 mhz Gigabit Ethernet and a cube. Both of which I'm going through the motions of upgrading and I have the following temperature related questions:
- When I see heatsinks on my logic boards and gpu's (an ATI Radeon 9000 Pro and 7500) that have no obvious way of removing them like I could with the CPU's, is it generally expected to leave those heatsinks alone and NOT put on a new layer of thermal paste? Are they epoxied on permanently? There are no clips/screws/etc, holding these heatsinks on so I assume it's glue.
- If they are permanently glued on and I assume the thermal paste/pad underneath them lost its effectiveness years ago, should I be more proactive in getting fans specifically aimed at these components, despite the fact that they were designed to be passively cooled? I should mention that for my cube, I'm putting in a fan.
- I don't even know how hot is too hot in the first place? What is the normal temperature range for a G4 and these GPU's at idle and under load? Really what I'm asking is what temperature should I aim to keep these things from reaching?
- I'm hoping to upgrade the GE from it's stock dual 500 to something like a dual 2.0 ghz 7448's. Does anyone have any recommendations for aftermarket heatsinks/fans that I can use? Or, would attaching a small fan, say the 40 mm one from Noctua, to my existing dual processor heatsink be enough?
- I've also seen a Digital Audio heatsink fan combination pop up on Ebay like this one here. Would this work in my GE?
