I'm printing with PETG at 235C, and my first prints are coming out really nice. I printed the PEEK fan shroud, installed it, and re-calibrated the PID values. I then printed a test cube. After that, I tried to print another shroud for the layer fan. The PEEK fan is really spinning fast, and now the hot end is unable to get above 230C. It tries, but it can't. Is there something I'm missing, or is it possible that the fan is working against the heater?
Can you slow down the PEEK fan? Is there something that happened when I imported the MC profiles from SeemeCNC website? These are the only two things that I think I changed.

Re: PEEK fan and extruder temperature issue.
I had the same problem.
I add a kepton take around the metal part of peek so the fan only blow on the plastic part and if fixed the issue. I did about 8-10 rounds of kepton.
Hope it will help you.
