Mosquito Magnum cannot PID tune at 235 or keep temp at 235 with fan on after upgrade.
I decided to upgrade to V-core 3.1, but the new EVA3 design discontinued support for my Hemera, so I changed to Mosquito Magnum and an Orbiter 2.0.
I used the cartridge (30W) and thermistor from the old one.
I printed the alternate fan duct, and am using a single 5015 fan. I have a sock on the heating block. I put thermal paste on the cartridge to ensure optima thermal transference to the heat block.
After the upgrade I cannot complete a PID tune at 235 degrees, and when doing PID tune at 205 degrees, it can complete, but during regular PLA printing at 205, the fan can max be at 50%, or heat can't keep up. Printing PETG at 235 basically cannot have the fan on at all, or the nozzle loses temp.
Anyone got an idea what's going on? (or have questions that can guide me in the right direction)

Alternate fan duct with the outlets behind as well as the sides? I had to add a silicon sock like you did and that fixed for me... though I am running a 50W heater and a RTD Pt1000. Sounds like you are, but my understanding is that you should PID tune at the temp you'll usually be printing at AND while the parts cooling fan is at 100%, assuming 100% is the fan speed you'll normally be printing at.

you should do PID with fan on, but it's just not possible if I want to print PETG, which is 235-ish temp. yes, it's the alternate duct with holes behind 👍
normally petg doesn't like 100% fan, but it seems super weird to me that I can't print PLA with 100% fan.
especially since it worked fine before I upgraded. I have checked for frayed wires on the hotend, but can't see any breakage.
Update: i disassembled the hotend, and noted that the cartridge from e3d is "only" 30W, not 40W as I initially believed.
Bought a 50W cartridge - no problems doing tune for PETG now. 👍

Glad that worked!
