Something was wrong with your old system. That's not supposed to happen. My Pentium 4, pentium D, core 2 quad, and core i5 ivy bridge stock coolers all have not had issues running at max rpm.
Of course it wasn't supposed to happen. The point I was originally trying to make is that the maximum speed you can choose is not the maximum speed the motor can turn.
When someone uses the term "max rpm" they are referring to the maximum rpm that the product is rated for. Which is the highest you can select. There was no reason for you to bring that up.

I highly doubt it will help though as BIOS setups are always configured by default to run fans at max rpm when the temperature is high. Your temperatures are perfectly normal for a stock cooler from what I can tell.
That BIOS configuration you are talking about depends of various things (version, chipset compatibility and other things); and the manufacturer, of course, as I said before.
For example, my BIOS is from American Megatrends and it´s compatible with Intel chipstes. The fan speed option is called "SmartFan", that make my CPU cooler to run over 3000 RPM if necessary.

Did you do that setting manually, or your PC does it automatically? Remeber that some systems allow you to activate the fan speed automatic adjust (even they let you set a max speed limit for that).
It was dell's do-not-change-our-case-for-one-that-wasn't-modelled-after-a-blast-furnace mode, so it wasn't really a setting so much as a revenge.
These days cpu fanspeed is controlled via PWM. They all run at 12v but cycle the power on/off. So at 30% the power is on 30% of the time. At 100% PWM it is on all the time and you reach the max rpm that the fan is rated at. Since your PSU won't supply anything higher than 12v DC the only way to make it go any higher than its rated speed is to hook up the fan to an external battery with a higher voltage.

None of the stock coolers Intel/AMD have ever made has produced behavior like what you described. Most likely that Dell system was not using a stock cooler but a special aftermarket cooler designed by dell (or someone else). I've had some Dell systems from back in the day that didn't use stock cooling.

That doesn't have anything to do with what I said. Like I said it's impossible to run the cpu fan faster than its max rated speed on a modern system and the vast majority of BIOS configurations are set by default to max it out when the temperatures are high regardless of the version or developer.
His temperatures are normal for stock cooling.
After opening up my brother's computer (the one currently housing that CPU/MoBo/Fan combo), it wasn't the stock Intel cooler, so it's possible the fan was designed with sonic-weapon usage in mind. I only discovered this when trying to take a picture to show it was the stock cooler, though.
As long as your chassis is deep enough to fit it (a normal sized midtower should be, a smaller desktop probably not). However the reviews on that cooler are pretty poor. Why are you interested in that one specifically?
