"Machine Room" temperature?

I just put my computer, drives, and expansion chasis in a closet. I have a thermometer that I can read in the control room to watch things, but what is a ideal temp range?

What is too hot?

What is bordering too hot?

In general, if you're comfortable, the gear is comfortable. But if you have alot of equipment in there, you might want to feed both a send and a return from your air conditioner into the closet, with the send blowing right on the gear and the return on the ceiling. Then leave the fan on your air conditioner on all the time rather than the auto setting, which only turns the fan on when the compressor kicks on.

I have two 10" ducts blowing right into the back of my machine room racks, and another 6" duct coming in higher up on the side.

IMO, air movement is very important. In many cases, more important then the temperture. Air flow is key.

As long as the air in your machine room is not stagnate, you're OK. Air conditioning can cause some serious problems if it's not always on. And I mean, never turn it off. Condensation may cause problems to your gear. The cold to cool to warm cycle can rust and/or damage your gear. Be careful when considering your requirements.

The common sense answer is that 80 degrees F is too hot
for long term happiness, and 90 degrees F is the limit
for even moderate times.

The exact number depends on things like the airflow
to the gear, the airflow inside the gear (computers
are especially bad), and the volume of airflow.

Most modern motherboards have thermal sensors
and can issue warnings, shutdowns, etc. when they
are too hot. Modern CPUs run hot, which is why
they all have huge fin banks, and fans. Often the
fans are noisey because they are moving lots of air.

Professional computer rooms are designed with
an air temperature that is uncomfortably cool.
Often 65 degrees F. The computers love it, and
the humans can wear sweaters or sports coats.
