If a managed network switch were to overheat, would you consider it no longer reliable?

Here is the scenario - I have a network switch, one of several in a stack. It's fan failed. Soon, there were reports of users with network issues. After quickly replacing the fan, the users were fine, network issues were resolved.

I assume the unit was overheating, and thus failing somehow.

Today someone suggested to me, that I should not assume the unit is 100% reliable anymore. So what do you think, would an overheat condition (less than 1 day with the fan stopped) potentially cause permanent damage that could at some point come to the surface as future network failures/issues?

If it matters, we are talking managed switches such as 3Com/HP SuperStack , ProCurve or PWR-Plus.

SQL Server database with clustered GUID PKs - switch clustered index or switch to sequential (comb)

We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs).
