High Temperature

I wouldn't say that, no ..
unless it is done by a professional.
If you have never done this, you may have difficulties, if you miss the change, that you make a mistake, the computer may no longer work, and there no longer a guarantee possible!
Up to you

Obviously made by a professional, but that could be better than risking to using this case for my warranty period and after that period maybe my pc will be "broken", right?

[Prométhée]

Sorry, I can't advise you on this
It is a risk to take or not, you alone have to choose what to do!
Your computer, could work very well without touching anything (although I doubt it)
Modifying a brand new computer, with no certainty of the result, at the risk of losing the warranty, I don't know if that is the best option, you see?
Personally, in your place if I could of course, I will be reimbursed, if the computer does not suit me!

Okok, i understand, btw i can't be reimbursed anymore, ty anyway

Basically, we are screwed once we have bought a HP product...!!!!

Hp warranty is not really good.  To be perfectly honest it is a mistake getting an omen desktop. I suffered with horrible temps for 2 years before I had enough had move everything to a new case. Now I have a gaming pc that can be put full throttle like it is nothing.   The warranty I had was worthless. 

Until moving to a new case you can set a custom after burner gpu fan profile. It helps alot and you should not see the gpu go over 70c with a good fan profile. 

Usually I reccomend 28c at 16 % then 45 at like 25% then 55 at like 40%  until 1000 percent. You get it just make it aggressive.  For the cpu leave the panel off or punch the top part out and had some fans.
