I bought a EVGA GTX 770 ACX in May of this year (2014) and being on September (less than 6 months) my card has some heavy corrosion or rust all over the plate that holds the fans and also the fins seem to be damaged, i need some advice on how to clean this parts or what should i do. The humidity where i live is around 66% and temps are 31°C/88°F normally.
 
I just opened my case to clean the dust and found this! i haven't applied any kind of liquid and the card is brand new, i unboxed it myself.
 
if i really have to, i´ll send it back for a refund or something, if somebody can advice me on this i would be very grateful.

I appreciate any professional advice on this subject since returning it is kind of diffcult since i bought it on Amazon and i don't live in the US.

thanks in advance.

Here are the pics on how it looks
 
 

Do you have something that measures the humidity in your room or are you going by what the humidity is outside? I ask this because on some days the humidity outside here is 50-60% however without my air conditioner on, humidity can reach 70% or so in the room which is way too high for my liking. With my air conditioner running I keep my room at 40-50% at all times.
 
Also if the ambient temp drops fast at night and the PC is still warm, moisture can build up quickly...

Humidity is an electronic killer for sure. In saying that, you should look around the inside of the PC a bit more. If humidity is the big issue you should see corrosion on the motherboard capacitors and anything that is metal that heats up for that matter....

I do not believe EVGA covers damage due to humidity as it is not a manufactures defect but I could be wrong. Hopefully its is simply a surface issue. However I would, as mentioned above look into a humidifier. At the least I would purchase a humidity monitor which cost about $10 here in Canada. 
 
The humidity in a room will be different than the humidity outside for the most part. Depending on how your house or apartment is insulated moisture can get trapped between the walls causing the humidity inside to be quite a bit higher then what is recorded outside.
 
Good luck  :)

I need to know what country you reside in but I will ask EVGA tech support if they have time to review your post.
 
 

Barranquilla, Colombia and i bought this card over amazon in may, thanks in advance.

Dear ajvelasco81,
 
I am very sorry as I can confirm that this type of damage due to the climate is not covered by the warranty process. I can recommend following the recommendations made by the other people posting on this thread as if the heatsink is rusting then likely other spots on the card and other electronic components will also rust leading to early failures with the electronic components.
 
Sincerely,
EVGA Customer Support

Well Thanks for the reply, i'm the one who is sorry for this kind of inconvenience, i'm the one who' s going to lose all the investment on a short period of time on a GPU that wasn't really tested on tough environments, not everybody can afford a/c or a dehumidifier and this is what happens after a really short time in this kind of climate... i really should've done a little more research about this and the quality of the components before buying. I really think this is a major flaw on the design of this cards, i mean, after 5 months and looks like this? c'mon!!! ... so dissapointed...

You should look to buy a replacement heatsink if possible. That will make it easier to maintain one rather than trying to backpedal the corrosion that is already set on this one.

Yeah Scarlet-Tech i though that too, i think this problem is way advanced... but i thought it was only possible to cpu's, do you have any recommendations of which one could fit to this card? is that standard? water cooler is better for this project? if so, which one? thanks

NVM. 

Is your pc case near a window ?
 
Perhaps its sucking in rain / spray, and causing the accelerated corrosion.
I stopped opening the window near my pc case because of a couple close calls when no one was home.

I'm not really sure the cause of this issue is humidity.
why?
I live at the Aegean what means humidity up to 90% at peak times.
guess what guys, I never had such an issue nor even heard of similar issue here.
 
no manufacturer warns on their sites not to buy their product while residing at the coast.
so what are all the guys at coast areas using? come on, the problem should be somewhere else.
 
@ajvelasco81
can you please post detailed pictures of your cards PCB, both sides if possible?

Do you have air-conditioning inside of your home?

@RBIEZE well, i moved it closer to the window to get some more "fresh air", is like 2mts/6ft away form the window, i also bought some plastic cover for it to protect it at night.
 
@WinglessWonder, yeah ill try to do that, thanks. About the coating somebody suggested (HeavyHemi) Scotch's 1617 Zinc Spray but i was afraid it would somehow reduce the heat dissipation causing the system to overheat and i don't know if i should do that.
 
@Sahafiec, Yeah, that's my point, there's no warning anywhere about this climate or the damage it would suffer after such short time on this kind of environment and surely i can´t find a lot of info about this issue. and Sure, ill try to post the pics of the PCB as soon as i open the case.
 
 
i bought fans to almost every available slot on my Thermaltake chaser A21 to inject as much air as i could to avoid overheating due to high temperatures on the area i live in, but i notice that the bottom metal vents on the front (the ones in the front with blue arrows) are rapidly corroding too. so i guess this might be playing against me.
 
this is kind of the standard setup and i did it like this too (one fan less on top) :
 

 
 
 
Some friend read on a German post that the guy solved most of the problem kind of shutting down any available intake fan vents and setting the system to a negative pressure (more air exiting the case via exhaust fans than fresh air entering the case via intake fans and vents) and also setting liquid cooling to CPU and GPU... It makes a lot of sense since you don't want much of this salty air coming in to your case isn't it? right now my system has 4 intake fans and 2 exhaust fans which makes it  a positive pressure system, i think ill revert that for a while and see what happens, maybe there's more to it but in the meantime it could help.
 
Also i chatted to NZXT guy and recommended kraken g10 and x31 and a dehumidifier so i'm considering this to save the GPU, because as you see, this thing is kinda way too damaged, those aluminum fins look like trash.

no, I don't use any by purpose - they make sick as the time goes on.

I completely agree with you. I lived close to the beach for several years and never seen or heard of this before ( Ps. humidity was always high). Yes, corrosion for those who live close to the ocean is pretty higher that for those who don't, which will cause  some items to  corrode  are a faster rate. However, this is ridiculous... He does not have the card inside the salt water, or over the sand unprotected, but in his home inside a case. There has to be something else here. Unless , he is so close to the ocean that the salt water goes into the computer ;)
