What is you fan speed?
And how fast is your actually print speed at the overhangs? Maybe show the print speed view.

Will let u know when I get home fan speed was around 80% on one of the better prints I did run it at 30 on a few

Here you go sorry about the delay

Can you take a screenshot of the speed view after slicing? The one on the "Preview" tab, with color sheme Speed.
That would make it much easier.

Yes, the speeds tab is important. IMHO Orca defaults have stupid fast speeds & needs to be slowed down. I question where they got those values from & if they even tested them.

Hope that works ok

Can't see shit.
On windows you can press Win + Shift + S to take an screenshot of an area. And then ctrl C to copy and Ctrl V to paste it in here.

Mhh, seem like the overhangs are at 10 mm/s, so that should be fine.
And the fan is actually working? I mean it does blow air?

I'm somewhat out of ideas.

I can see that ~something~ is being printed at 392 mm/s, which can be quite fast. As a test you could set the maximum speed to .. 120 .. just to test it. But I doubt that is the issue.

Yes just looked fan is working and blowing air as for the max print speed just trying to find the right setting now thankyou
