Hey there. I was doing a search online because I was having this same issue with my Ender 3 V2. I thought I had a bad thermistor so I replaced that and ran a test print. Had the thermal runaway error throw at the 4th layer. Went ahead to do the print and thought maybe the cooling fan was throwing too much and cooling the hot end. Noticed that when the fan started to fire up and especially at max speed, my hot end couldn't keep up. Thought this was strange since I've never changed any settings and after I started using PETG over 230C this became evident. I saw places saying you could replace the silicone sock, but I don't think that would do anything.
At this point I'm going to run a print for a new fan shroud to get the flow to the base of the nozzle and away from the heat block at about 30% fan speed (around 85 on the print screen whatever those units are) and then once I fit the new shroud to the unit, give it a shot at full speed.
Curious if you had any issues since.
