FIG.1
Here's another way to cool down your receivers.
To make this project you'll need the following parts:
1. Op AMP
2. 10K Thermistor
3. 10K Trimming Pot
4. 12vdc fan

Note:
--Attach thermistor close to heatsink/fan.
--10K trimming pot is used for user's preferences. This way fan will turn ON automatically depends on the setting.

Actual picture will follow soon....

Warning: BUILD IT AT YOUR OWN RISK!!
