ContactTechnical Support and ask about cleaning to remove dust from fins etc..
I had an older GPU that opened like a clam shell for cleaning out dust and debris.
Lots of cleaning info on the internet. Do not do any of that.
Instead, contact the manufacturer and ask.
See if they will provide any cleaning information and confirm that cleaning will not void any warranties.
Dirt, dust, debris trap heat. Heat is an enemy of electronics. Cooling and cleaning are mandatory.
Well the warranty was void before because I had to RMA the card due thermal issues and the brand said that have to pay all the cost on shippings ,so I went to a store and asked if the chip was a issue , and was not so they only changed the thermal paste and it's working untill now with 75 to 76°c on unigine heaven benchmark . So I was only afraid that could be some rust and that rust could damage the GPU in some time .
I know that have some dust on other parts on computer but nothing extreme that make my conputer heat too much at least I think so by my knowledge and the internet opinions .
Btw my computer temps under full load on really stressfull benchmarks like the one I said are like : 55°c on cpu , 35 °c on MB and 75°c on my GPU .
I take care about my computer , sometimes even a little paranoid about it .
In case of being rust it can damage the card if it is oy on the place it is now ?
