GPU heatsink cleaning

[Eaglesnuke]

Hello

 

so after many years on online gaming and after colecting parts for the last 10 years i decided its time do something with them

 

i got an old saphire hd 4890 that runs very well except for the part that it heats up very fast

 

went on you tube watched tutorials got it open cleaned everything but the heatsink is  ''Corroded' anodized...?

 

does anyone know of a good way to clean it up?

 

Thank you

Usually you clean the heatsink itself by blasting it with compress air. To remove the small bits of dust that still stick to it you can use some paper towels and alcohol.

 

I'm not a chemist but heatsinks are mostly made out of copper pipes and aluminium fins. If it actually corrodes that means it came into contact with water. That would raise some question about the history of the card. Don’t quote me on this one.

for better understanding i put 2 pictures

 

i always had this card it was new

 

i do live in a humid place

 

will this impact much on the heat dissipation or just put in new paste work because the old one was bone dry

As long as the airflow channels between the fins of the heatsink are clear, I'd put some new paste in & call it good. 

It might be a smidge hotter than factory condition, but I wouldn't think by much.

It does look a little tarnished, but as long as the heatpipes are still sealed they should do their job. And where they connect to the aluminum fins is a closed space so there shouldn't be anything in there to hinder heat transfer.

Dip it into apple cider vinegar overnight. The next morning, rinse it with water and blow it with compressed air.. Vinegar is the best solution to clean corroded and rusted metal, but the apple cider vinegar is the strongest one AFAIK.

will try it out

Did the apple cider vinegar work out? I'm having the same problem and I'm getting mixed solutions. Some are saying to use baking soda or clr but so far I haven't seen or heard of any success.
