Seriously, why do you say that? There are thousands of printers out there using that chip, including mine - my printers have been running nearly 2 years with no Mosfet problems and I only have a small heatsink and a 40mm fan on mine.

Thank you guys, I've tested outside + fan + heat sink.
still having issues with slow heating (more than 10 minutes to arrive to 95 [c] while temp goes up than down than up again)
since the heat was sounded like a real issue I've tested that & with the fan [2000 RPM] I don't think that the MOSFET over-heating and I would expect to feel the heat when I'm near it but the fan does it's job & I fell the heat ONLY from the heated bed.
I would prefer to make sure that my setup is OK before switching to another MOSFET.
I'm not sure that my 5 years old PSU which suppose to deliver 450W (and up to more than 16 [A] according to it's spec) is giving the 10-15 [A].
How can I test that? my DVM is up to 10[A] is there a way to test that without new DVM?
