Post a Photo of your Computer with the Side Cover Off and make sure the Photo show the completed Side of your Computer.
Also post a Photo of the Front with and without the Cover Installed.

Well as i said in the last post i don't heat my home and its -1c outside. So the house is a little warmer then outside but not by much so i would say perhaps +3c to +5c MAX inside the house and in my den that i do my streaming from the door is always closed and the PC is next to a very old school so where the PC is located is the coldest part of this small room. By small i mean all i could fit in this room is a desk, a chair, and a book case. I barely fit in here haha! also here is a screenshot of my idle temps while i have been talking on the forums.
 

If you read the very first post i posted i included a list of all my PC specs and fans. There are no fans facing the front although the fan on the lower which is listed in the first post
I will take a quick photo of the room and where the PC is located etc. Although could you please tell me if my temps are okay or not like am i at risk of anything etc?
 
\/Fans\/
Exhaust Fan: 1x Corsair Air Series 140mm Quiet Edition High Airflow
Side Panel: x2 Corsair Air Series 140mm Quiet Edition High Airflow
Top: 1x Coolermaster Megaflow 200 - Sleeve Bearing 200mm
Buttom: 1x Coolermaster 120mm Silent

Don't worry about it.
Can you set the computer to the Right side on that small table on the right side where the Pepsi Can is?
This would give the Side and back of the Computer clear air intake.
The Side of the Case looks block by the Monitor and close enough that it may be pulling in the heat of the Monitor into the computer.
I see what you mean about the Front.

"GPU Temps go up to 60 and 75c" and that is ok for that card.
Have you removed the GPU and given I a good Blowing out (Hold the Fans From Moving)?
Maybe time to re-TIM the GPU as well, MX-4 is what I would recommend.
Are you using a Fan Profile or setting the GPU fans to around 60% and are your Temps still hitting 75C?
Do you use PXOC or XOC or MSI AB?
I would try and stay below 80-85C but the max is 90C
At lease you have a Windows for the Summertime to put in a Window Air Conditioner.
 

This is what my current fan curve is set to in order to get the temps i am getting.
My temps were a bit higher before i changed the curve to this.
 
 

Maybe then before this coming summer you change the TIM on your Graphics Card.
But other than that your computer looks ok.
I would wait for other Forum Members to post what they think.

This is what i mean about my high temps while gaming tho.
 

some games can load a card to run hotter  70-80 c range  at max use  / load   is a normal average 
 
now your room air temps will affect things as well    cant expect the rooms air temp to be 80   and have it to air cool the card to 65   so the colder the room air temps are the cooler these parts run  due to colder air to circulate  and dissipate heat
 
could look up threads as this on that one game

like said here
''I'll add that, effectively, OP has said that this problem happens in all games, it just happens faster in Naval Action - which makes sense as NA is not yet optimized ''
 
that can add added stress  that can help to heat up the card    poorly optimized  means more work on the card to render things smooth

if me  you pic of you rig looks nice open and clean   so   I would grab hwinfo64  to monitor   then grab 3dmark firestrike   run the basic  1080p  bench 3 times  then look at the  hwinfo chart  of readings    and see what the card is doing   max min and average   temps fan speeds , ect...
 
then post that screenshot here to look over  .

firestrike  [where I got mine . but you can get from where you want ]

try that and post the results from hwinfo64    [for a example ]

well i think that catzilla is a malware   i tried it and got to noticing  suspect things  and removed it  and them things went away with it  ????  don't know ?
 
thing is using something that's a stress test that can and will  run a part up till it crashes or fails  and can a lot of overheating  of them parts  or just plain cause damage  .
 
something like basic  firestrike  should give you normal like everyday use  runs   you hardware should run as normal and expected
 
ticking noise ??  can be anything from a wire dropping in to a fan  or like you say a hard drive going bad  ?   that's something your going to need to pin point the part its coming from  .  a lot of these cards with that was due to the fan wire dropping in to the fans blade at a certain speed  or airflow draw , just adjust the wire fixes that .  or the screws of the fan mounting to the cooler bracket  [3 small ones  just under the blades ]   can loosen and cause the fan to clip the shroud  ?? or a fan got a bad bearing/ dry ?   some fans got a service plug  on the bottom under sticker to use to put a drop of lube in

now some fans don't have this as well and  non serviceable  [ you could get messy and use wd40 with its tube  to try to squirt up and around the impeller hub of the fan  ??]
 
 

ya, anything 80c and below in this room of mine on air is called good enough    and ok with  full max loads  .   cooler is always better , but sometimes its not the cards fault  like said all above
