can someone tell me what this could be?
I have notified the seller and he acknowleges its existence and Quarantees that the card works fine. I asked what he thinks could have caused it and he said he had no idea but he hasn't had any problem with card at all
I have tested it and it seems to run fine. Fans idle at 46% and is a bit louder than my near new Gigabyte GTX 760 which is at 20% idle.
Card is old (dusty) and out of warranty so i think a good cleaning and fresh thermal re-application would help lower fan idle speed but am just unsure what the black deposits are and whether it can be easily cleaned.
I am in the process of deciding whether to return for a refund or keeping it.
thanks for any advice
