fan airflow & temp indicators

[Dilbert Firestorm]

my tower antec SX1240 has 2 single speed 80mm fans located at the rear
which serves as the exhaust fans

the tower has 4 openings for 3 80mm (front)& 1 92mm (rear) fans.

I'm getting 3 80mm variable speed fans for the front for cooling.

however, I'm undecided on what to do with the rear 92mm fan opening.
should I get a single speed fan and make it the exhaust fan or get a
variable speed and make that the cooling fan?

also, is there a good temp indicator device that I could pop into one of
the drive bays?

Why do you think you need more fans? Give system specs + CPU and system
temperatures.

as for why I think I need more fans, cause I want to.

dunno why you want my PC specs.

You want to arrange your fans for a defined airflow direction.
If the ones on the front are intake, then the ones on the rear
are exhaust. The front are intakes, to keep the drives cool,
leaving the other side of the PC for the exhaust.

For sensing, these are the deluxe versions. They include
fan control and temperature sensing.

(There are a few different models here, some with more ports
than others. Some linear, some PWM fan control.)

If your budget is a bit smaller, I got one of these a couple
years ago. This one runs on batteries, but you could always
find a 3V regulator and build a permanent connection to your
ATX power supply. There are probably other versions of this
around, that run from a disk drive connector - I just picked
mine up at a local computer store, and since I was in a hurry,
didn't worry about the details until I got home.

I found this one by looking for 3.5" LCD Thermometer. It
has a disk drive power connector, so no wasteful batteries.
Example only, as it is out of stock.
