No post from the OP https://lists.ubuntu.com/archives/ubuntu-users/2013-January/266548.html prior until yours that I replied to https://lists.ubuntu.com/archives/ubuntu-users/2013-January/266552.html 
contains the non-attributed string "Fan speed 1800+". How is _anyone_ supposed to figure out where "Fan speed 1800+" came from or what the basis for your next statement was? It looks to me like a 
spurious interjection.

Nothing I wrote says or implies increased airflow can't or won't help.

My reply was about your malcontexted reply to the OP, using the context of thread posts received up until I composed. The OP described nothing about the cooler actually installed, so to say 1800+ is 
not enough followed by "you'll want 3000 to 4000 rpm" is indeed nonsense, and spurious, as the only context, observed temp, and CPU type, are inadequate to support or justify such a statement.

How you spend your days is no justification for an unqualified claim "you'll want 3000 to 4000 rpm" having been given such skimpy information. Coolers exist that make necessary no fan at all, while 
categorically as a group, higher speed fans do fail sooner. _I_ certainly would be highly unlikely to _want_ any 4000 RPM cooling fan, even if it meant choosing a different CPU/socket type to avoid it.

Maybe someone broke the threading, but even now on the archive there are only 12 posts in the whole thread, all of which are still in my *buntu folder. If it is the case that the thread was split and 
I missed something, or you quoted something from a private post, there _might_ be something to apologize for upon show of proof.

My response would probably have been avoided if your reply had included any attribution whatsoever, but none appeared that I can find in the archive. Thus, there's no reason to retract anything I wrote.
