Thanks My previous set up was the same with an undercounter fridge but without the fan.It is just the new tall fridge which needs some help moving the air around. Thanks for the post
Anyone fitted a brew fridge fan

Hi @110ben
In a closed environment, one would expect the top of the fridge to be warmer than the bottom. Have you taken temperature readings?
I suggest that holding the sensor in air is the cause of your misgivings. Try putting two identical vessels containing water into the fridge and fasten the sensor to the outside of one vessel, making sure that it's insulated e.g. with a kitchen sponge. Monitor the temperature of the water in each vessel over a period of a couple of days.
My suspicion is that there will be a very small, if any, temperature difference.
I don't bother with a fan because I don't think it is needed.

Thanks for all you replies and based on all the info i have decided to do the following.
I scavenged a pc fan out of an old broken pc. I have a 12v adapter which i use for a pump.
I found some 12v connectors on ebay for a couple of quid so i will adapt the supply to be able to work both as they dont need to be running at the same time. So not sure if needed due to natural convection but if nothing else it will give me peace of mind. Once again thanks for all the info and advice.
Time for a wee glass of wine I think.....hmmmm red white or rose decisions decisions..

Ah, but which way do you need to push the air? Will you fit the fan at the top of the bottom of the fridge? :tinhat:
On a more serious point, what shelving arrangement you have going on? If you've got a thick solid shelf going across the middle, you've actually got two separate boxes and the warm air is going to struggle to rise. You might therefore need to drill a few holes in the shelf (assuming it's wood of course) to make sure the air can flow freely and heat the top.

Such complications
Central shelf is solid but has large gap at the back as well as the front so air movement should be fine cheers...another glass of wine needed

You could drill a hole big enough to match the circular area of your fan and mount it under the shelf with the air flow pointing down to draw the warm air from the top of the fridge.
Hi!
In a closed system as small as a fridge you could place the fan anywhere and get decent equalisation of te,mperature.
