My gpu fan was making a loud noise and burning smell coming from it so I wasn't sure what to do, google a little and found Mr Armand's thread.
I read a few comments in this thread and found a few bad reviews, so I wasn't sure whether to send my gpu to Armand in case I don't get it back.
But I am glad I did, I whatsapp Armand on 30/01/2021 and told him about the bad comments I saw and he explained to me and told me the reasons for those comments.
So I asked what is the problem with my gpu and he asked to send and get a diagnose first will only take a day.
So I whatsapp him on 01/01/2022 and he fix my gpu right after I msg him on New Year and said I could take it back that day.
I am very happy with the service and he is guru on fixing gpus, I even got update on my whatsapp with video on how it is running after being repaired

Problem sovled after:
Changing overheat mosfet, repairing faulty fan, changing thermal pad & thermal paste. One week already and still no problems.

For those wanting to get fast replies don't pm Mr Armand in forum, whatsapp him he is busy and it is easy for him. You can also post here to get his attention, if Mr Armand personally work on your gpu you can get it back faster but this is subjected to his availability.
