Keezer Temp Fluctuation

[Sdiddy84]

I'm just wondering how much fluctuation everyone gets in their keezer.

I just hooked mine up and seem to be getting a couple degree (in Celsius) swing. I have my temp controller which is an inkbird itc-1000 set to 5° with a differential of .5°
This morning it was down to 3.7°

I figured there will be some fluctuation considering the lines are still cold after the Compressor shuts down.

I should also add that the temp probe is calibrated and sitting in a jug of water. The keezer is also empty for the time being. Just trying to work out the kinks and learn before I keg my first brew.

I'm by no means an expert on this, I'm actually in your same position, getting ready to keg for the first time with my newly made keezer. But I'm not really too concerned with temp fluctuations because I know the freezer will kick on before beer begins to really fluctuate in temp being that liquid holds temp longer. I'm going to setup mine to stay between 35 and 39 degrees and monitor with a thermometer for a day or 2 to make sure it doesn't hit freezing for any reason. Not sure if this is your concern or not but that's my plan.

you make a very good point with the liquid holding temp longer. That never crossed my mind.

It will become much much more stable once you have kegs in there. Also a fan is a must in a keezer to minimize top-bottom temperature differences.

Just curious but what kind of fan? I know pc fan but one that connects to usb be good enough?

Sure, a 5V fan will work fine. It really doesn't take much air movement to prevent the otherwise inevitable thermal stratification inside a chest freezer.
This USB-connected fan has quite a few fans on HBT...

Cheers!
