The reason I post this is becouse I learnt that graphics card do need some cleaning once in a while. Cleaning of my gtx 660Ti made it 8 degrees cooler while playing bf4. The cards is making less noise aswell. From what I have read some cards will gain power as they cut it in higher temperatures. All cards will gain longetivity if cleaned properly.
I visited a friend two days ago, we are not IT technitians or anything, just advanced users with brains 😉 We cleaned his Radeon r280x and mine 660Ti. The process is not very difficult but one should pay attention and be careful.
What actually needs to be done is : 1. dusting the radiators 2. replacing the thermopads 3. cleaning the old and applying new thermal paste. 4. You can also apply some WD-40 to the fan engine.
There advanced tutorials in the net (will post links below), If needed I will describe the process, but my main point is that You can and probably should do it ! The old thermal paste is the only item that moves the heat from your GPU to the radiator. With time it losses its capacity, becomes hard and basically stops doing its job. Same story with thermopads, the diffrence is thay are not liquid and they lay on RAM. Dust in the radiator is obviously harmful aswell.
If you are interested there are some tutorials :
Be brave and love you GPU <3
