Hello, I recently installed (4) - 4gb RAM modules and I'm worried that they may be running too hot. The image attached is from the machine just essentially sitting idle all day. Only 1gb of the 17gb are wired. When I do put the Mac to work, either through Handbrake or running Autocad through Fusion, the temp on module A1 reaches 173 degrees and the fan speed just about doubles. Is this something to worry about?
