I already try putting the fans slow but no help i also turn them off and same thing.
Thanks for the suggestions i will defiantly try them now and i will post update.
Btw i just found when i go to maintenance in the ultimaker and if i start extruding material rapidly the temperature drops quickly and im able to do the same error without waiting for the print so probably i have as you said really week heater probably 20W and when material get extruded fast the temperature of the heater start plumbing.

just set fans to 50% to get this part done.
If you aren't in a rush I recommend you get a 35W heater. If you don't want to wait for that you have several options:
1) The UM comes with a 25W heater which is plenty but yours might be lower as there is a large variation so you might only have a 20W heater and you are pushing it too far. But I also see you have an olsson block and this error is very common because your Olsson block is probably touching your fan shroud. So you can try to fix that - for example raise the block up higher by tightening that round nut (no disassembly necessary but heat the nozzle to 170C first in case there is plastic in the threads). Or you could put polyimide tape between the block and the fan shroud. Or you could remove the fan shroud. or lower it slightly by loosening the four screws and pushing down and tightening. or you could just run your fans at 50% instead of 100% (that will definitely help avoid this error!).
2) You could get rid of this error in the firmware. It's a safety thing in case your temp sensor falls out or your heater falls out but I have this disabled in my firmware and have printed for years with no problems.
3) Like I said, you can just get a 35W heater.
More about the feature and the firmware and where to get older firmware:
You get an error if the heater can't move a certain amount in a certain time while driving full power (when it is close to goal temp it typically runs well below full power):
Firmware
Version
14.09 - does not have the feature
14.12 oct 16, 2014 - feature introduced. 20C in 20 Seconds
14.12.1 dec 15, 2014 - from 20C to 10C (still in 20 seconds)
15.01 jan 14, 2015 - from 20 secs to 30 secs (now 10C in 30 seconds)
So for example you could download cura version 14.09 and update your firmware using that firmware version. Cura is unique in that you can have dozens of versions all installed at the same time - each version is treated by windows as a completely independent , unrelated program.
