I have got on to a computer shop who can sell me a second hand computer fan. Now he said they they are either 5v or 12v as they are the two rails in a computer.
Now I have 2 AC adaptors a 9v 350mA and a 10v 740mA.
What combination should I go with?
Thanks champ!Yeah theres 5V and 12V rails in a computer power supply, I aint never heard of no 5V computer fan though.
Get the 12V fan and use either adaptor - theyll both work fine.
I have found a place that will sell an 80mm for $8. Now are these quiet or not so much? And is this going to be big enough for a 200l chest freezer?

Eric, I recently put an 80mm fan in my 300lt chesty and it works fine. Freezer is an ambient 3 degrees top to bottom.I have found a place that will sell an 80mm for $8. Now are these quiet or not so much? And is this going to be big enough for a 200l chest freezer?

Ditto. Never seen a 5v fan.Yeah theres 5V and 12V rails in a computer power supply, I aint never heard of no 5V computer fan though.
Before the addition of the fan, the air in your freezer was stratifying - cold air at the bottom, warm air at the top. As time goes by, the layer of warm air grows thicker until it contacts the temperature sensor. That process used to take an hour. Now that you added a fan to stir the air, there is no stratification anymore. The compressor will thus cycle a little more frequently. Nothing to worry about.
The thing to consider is that with the fan installed, the entire contents of the freezer are at a consistent temperature and the temperature swings within it will be much less than without the fan.
