you're getting lots of help in your multiple other threads but here we go
1 - The PSU is sucking in air NOT blowing hot
2 - If there is no improvement on stock then it's because you have screwed up. Try removing the cooler, cleaning all paste off properly, repaste then remount. The cooler works fine pointing that way yes its not perfect but it will do it's job.
3 - What are you calling "no improvement" you know at idle there will be little change its at load you should be seeing lower temps.
4 - You can only mount the TX3 that way the photo you post showing the otherway is not a TX3
