Heat sensor? Answered

I need a heat sensing circuit that detects, if my server blows out warm air to switch on forced ventilation.
This module should work as a stand-alone module without any connection to the server.

I'm good sometimes...
Can you fix this with ducting or is the box too big?

Well, since you didn't exclude the simplest solution, you got the simplest solution.

In that case I recommend the Micrel Mic502 IC, which uses a thermistor to give you a PWM motor speed control. Perfect for your requirement.

Just run an exhaust fan ALL the time - Over cooling isn't a problem for a PC.

This is one of those "Guess my problem?"-questions.

I guess that you've got a computer in some kind of box or cupboard, and you know that it gets too hot because it's in a box.
So you want something that effectively takes the place of opening it up to let hot air out. And you want to just leave it alone.

-Make sure the fan that the server already has (server blows out warm air)  is blowing out of the space that the server is in, and that you've got a cool-air intake. Some kind of ducting should do it.
