The problem with constantly maximum rpm

Okay, listen (read) guys, just get me right.
Significantly, I have two vidyuhi: "GTX950 (2gb)" and "RX560 (4gb)". The first was "Green", everything was ok ...
I bought and put on "Red", bought from Alik, came with a good chip, was delighted, put it on, the cooler hummed alone. Disorder.
I decided to transfer the cooler from Zelenaya, since there are no coolers for vidyuhu in my Zhapinsk. Put 3pin to 4 pin. 2 days the flight is normal and on day 3 it just cranked up the speed to maximum speed and did not lower it. Does not react to anything, utilities have no power before her. In AMD software, the reaction is zero, well, it is clear why, pins are 3, there was no agreement on the control of revolutions. But why did she throw them out of the blue and arrange an airport on my table? Further more interesting ...
I listened to this chaos for 3 days, I mean howl vidyuhi and my family about: "What the fuck are we living like on the side of the runway." The cat still hasn't returned home ...
I decided to move everything back to the old one and sit on it until I buy a normal cooler for Red. I put the green one, removed those firewood and put those firewood, and she HOW LET'S SHOUT again. I'm on treason in googel, there I found old "chuchut", they say firewood should be removed. Deleted. Ohr is gone, but what should I do without firewood? I put the firewood with my right hand, I squeeze the cross with my left ... The
miracle did not happen, as soon as the firewood stood up, we went to take off.
The answer lies in that first time, I Shield, when she started yelling. The load at that moment was not at all, I just sat watching the film.
It was as if she was working, and then "Let me put some pressure on the vent, otherwise we sit bored."
In general, I am emotionally exhausted and will soon be physically mutilated if the problem is not solved ...

PS in utilities the number of revolutions counts from 6 to 12 thousand. This is utter chaos.
