If this is the first time you replace a heatsink, then first read up on what is involved. Look on the web, but here's the main points:
The metal of the heatsink doesn't sit on the processor directly. There is a thin layer of thermo paste between the two, because otherwise the two hard surfaces would not have proper contact. Sometimes a new heatsink comes with a layer of that stuff applied, or the existing layer is still OK. But to be prepared, you would need a plastic business card (to remove most of the paste), acetone and cotton swabs to remove the rest, then alcohol to really clean the surface. And of course new thermo paste. Maybe you know all this, but I thought it better to make sure and punch in some lines before you damage a nice CPU! Usually, Sonnet upgrades are well-designed, meaning that they have appropriate heatsinks or work with the heatsinks on the CPUs they replace. How do you determine that your model is generating too much heat? Did you tell the support guy the temperature? You're not overclocking it, are you -- or using it on a higher system bus speed than it's meant for? That's my 2ยข... -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
