Will definitely switch to a condenser.

Eddie, just got my M40 replaced about a month ago.
Is it a very new fix?

Actually Eddie, the reason I sent back my last M40 is that it made
a high pitch noise in the room. It's an uneven noise, kind of similar to a mix between a hard drive chugging and a high pitch fax machine.

But the new M40 is producing pretty much the same noise.
It's not super loud. But as my control room is really quiet it's audible about 1-2 meters from the center section.

Really surprised to find this on such a premium product!
I'm I really unfortunate to have had this on two M40s in a row?
Or am I over sensitive?

Would have guessed that other people would have reacted to this if it's a common issue.
