So you admit you either cannot follow a conversation, or at least not this
conversation? At least the OP did, and that's all that's important...

Nice. You offer insults and really nothing else. No help or solutions to the
OP, and no disproof of anything I've said. It appears as if you have no idea
what we are talking about, and in the end, spam the conversation with a lot
of words that add up to the actual nonsense you mention. 

Well, I stand behind my statement:

1) I solve these kinds of problems for a living, and I have in fact
installed faster fans to make a CPU run cooler. Many times. Sometimes the
replacement coolers people buy have the wrong speed fan. Sometimes the stock
cooler isn't doing the job. Moving more air through a heat sink makes it
cooler. That's just how it works.

2) That crap about smaller vs. larger fans has no place in the conversation
- a person should use the same sized replacement fan or it will not be as
efficient. It won't even mount properly. 

3) There are a few ways to make a given sized fan move more air: spin it
faster, or design more efficient blades and bearings. Spinning it faster
must be cheaper because it prevails in the marketplace.

4) In the conversation with the OP, I've mentioned case fans and PSU fans so
at some point you have to trust that the OP is aware of airflow. You also
have to trust that the case maker has put some thought into the design that
deals with airflow. I've seen the insides of thousands of cases, and most
have. Even a lot of the low-cost cases do pretty well.

5) Right now, I have a 95w, quad-core Bulldozer sitting on my build table
that came with a very nice heat-pipe cooler designed for the CPU by AMD.
(retail box) At idle the fan is spinning at 3245 rpm, and the CPU
temperature is 41C/105F. It's a variable-speed fan that is capable of
running a lot faster. It often jumps to 3308 rpm as I watch the cpu creep to
42C/107F in the bios screen. (I have the house heating because it's cold
outside)

So please, explain how increased airflow is not the correct solution if a
person desires a cooler temperature? 

Or maybe add something meaningful to the conversation? Otherwise I suggest
you keep the 'utter nonsense' statements to yourself and stfu.
