I'm new to using digital probes I've always relied on my lid thermometer and a instant read digital thermometer for the last 9 years. I bought a 4 probe digital thermometer first and now I have a fan also. Where do you set your top vent at with using a fan do you cut the airflow down just like not using a fan? And my lid thermometer is brand new I'm seeing a 50 plus or minus a fee degrees off from what my interior probes are reading.
To make sure it wasn't the charcoal causing this I put in my deflector and still getting the same discrepancy. My fan interior probe is within a degree or two of the ibbq-4bw probe. I have the ibbq-4bw roughly same height as my lid thermometer through my top vent for testing. My lid is reading 250 my probes 305/6.
And a pic of the queso I made last weekend.

I have a Signals / Billows setup from Thermoworks and the Smokeware cap on my large Egg. When I’m using the Billows, the bottom vent is closed up as far as I can around the fan adapter plate, and I leave an opening about a toothpick wide on the cap. The fan will force airflow as needed to maintain temp, but I never use the Billows at an ambient temp above about 275.
As far as the probes / dome thermometer goes, I’d trust the probe over the dome thermometer unless I had a very good reason to suspect a bad probe.
