I've now had my GTX 750 for almost a full year (bought it late Feb).
 
It was also my first ever "proper" GPU, and as such I do not know much about how to maintain them.
 
Over the past six months, I have seen that temperatures under load have been steadily increasing. It used to be max of 65C at max load, but now it breaches the 80C mark.
 
I opened up my case and had a peek at my GPU. Sure enough, it is covered in tons of dust. The fans look bad. I used my fingers and a brush to take out most of it around the fan without removing the GPU. However, I feel that there is more dust inside.
 
Now, my question is, should I remove my GPU from the PC casing and then clean it up properly? If yes, how do I do this? For the life of me, I can't figure out how to take it out and I fear I will break the GPU. Once removed, do you reckon I should unscrew any part of the GPU (if possible)? How do you reckon I give it a proper clean-up?
 
PS: Which other part(s) of my PC do you reckon I should clean up as well? The RAM, CPU, motherboard etc...anything that needs being dusted properly?
 
PSS: I have noticed louder idle noise from my PC over the months as well. When I check my GPU temps and fan, temps show 39C and fan at 40. This was exactly the same when I got my GPU at launch. As such, should I suspect the louder noise is coming from some other component (CPU fan perhaps)?
 
Thanks!

I have no pressure system or canned airs. Any "conventional" methods instead? I know this won't achieve 100% cleanliness...but I'd be happy with 80-90% improvement.

Easiest route would be to get some canned airs. You could just remove the card and get a balloon then blow in it for a bit twist it then attach a basketball air filler needle and aim and repeat x25 lol. But honestly a air compressor is the choice for everyone it has many uses not just dusting. You can find a Pancake Air Compressor for like $60 shipped and avoid the headache by cleaning everything!

Personally, every few months I like to take the cards out of my system, and take a q-tip to the fan blades, then hit them with compressed air :) pretty easy cleaning, and your GPU will appreciate it!

Oh so it is ok to use an air compressor. I thought it wasn't recommended because air compressors tend to create moisture. And moisture is bad for electrical components. I use one anyway but I didn't want to be responsible for him messing up his PC.

Thanks for bringing that up I dust my pc every 2-3months and whatever moisture comes out was evaporated quickly its not like I was spraying mist. I have a larger air compressor which I drain every few weeks but he would be using a small portable pancake air compressor which can be drained easily after each use.

Yea its much easier with air but I had to use alcohol and q-tips to clean the heavy dust off the blades which the air compressor couldn't remove. But the q-tip thing is done like 1-2 times a year it really takes time for it to settle in. 
 

Best way to get clean...
