Hot in Dubai

How about Heat?
 
As someone being forced back into Solidworks and then providing renders for my business, I found this video quite informative.
 
My question is heat.  I live and work in Dubai.  The coolest ambient my PC will see for 9 months of the year is 28C (82F)
 
Currently I'm just running a standard I7 5930 and a 980Ti GPU  my case has 2 x 140 intake fans, a 120 at the rear and 2 x 120 on the top mounted radiator.  At idle I'm seeing 48C (118) on teh CPU and 60C (141F) on the GPU
 
If I put it on test (using cheap free down loaded software)  I'm seeing 81C (179F) at the CPU and 76c (170F) at teh GPU before it throttles down.  I have no idea it these numbers are bad or indifferent.  Building PC's isn't' my thing
 
So my question is; If I upgraded the recommended hardware am I going to have heat issues leaving everything else the same?
 
If I need a bigger case, bigger coolers fans etc, fine I can do that (Frankely a new PC is a drop in the ocean compared with the software)  I just want a clue before I spend money as reliability and constant operations in my concern given it's my business and income.
 
PS.  If anyone from LTT chips in with advice I'll reciprocate with free advice and help on TV studio lighting, because that's my job (and their janky set up triggers my professional OCD every time I see it  ) 
 
PPS if they want to conduct proper hot weather testing I can give them 48C (119F) ambient in the shade and truly test your coolers  
 
Thanks in advance

Because it was the first and only expensive overkill thing on LTT ever and never shall their be an expensive overkill thing on LTT.  

Now you see LTT really need to get to play with Big Boy Media servers - the type that control all the content on the screens at concerts.
 
8k video in each of the 16 layers pushed out via 8 outputs (although its only HD)
 
You thought your keystoning was hard.  I saw a demo where they mapped the moving images across 6 30' trees outside  - In context the images just hit the branches and the leaves, and followed them as they moved in the wind.
 
Linus would wet his pants in excitement if got to see and play with those... 

Sounds like you need a cooler upgrade, but 80C is far from worrying, until its near 100 it's not going to hurt anything.
