[citation][nom]muhfq[/nom]In past we have seen lots of thing purpose… but out very quick… this is true.. Mineral oil is bad conductor.. But It is not bad as Air.. 2nd it could big messy if you have add and remove hardware.. Might you have wipe out the connector before installing RAM.. lol…[/citation]
Servers are usually replaced instead of upgraded. I don't think that oil getting in unused slots would be a problem.
Also, although mistakes have ben made in the past and are made to this day, this isn't the sort of thing that they're likely to be made about. We've had the technology to do it right (and have been using such technology in varying ways) for years, perhaps decades. It's not even a very difficult thing to do when you think about it. Screwing it up would be like screwing up a server design without oil and to my knowledge, Intel has not messed something like this up in their decades of being a company. Sure, it's possible, but it's simply not likely.
For example, how often do you buy or build a high end, professional/enterprise-grade computer and there is a major, inherent flaw in the cooling that causes quick failures? It's not common AFAIK even in more complex cooling such as water cooling, phase-change cooling, and such, at least in the enterprise markets.
