Yeah its normal.. can clean most of it off with isopropyl from the pharmacy. Get 91%. And qtips.

for people who don't want to click links from the internet ....  ..to me it looks like solder residue or where someone tried to clean it up before selling...?

The reason why it's around those connectors is because they were put on with a wave solder or selective solder process after SMT, the rest of the board was masked. No-clean flux residue.

Yup.. like I said I see this stuff everytime I pull a heatsink off to install a water block on a new card over the years..Normal but can be cleaned off. No harm either way.

You seem very sure about what your looking at. Thanks...

To me it looks like someone placed a non-conductive material over those solder points (pinouts) to cover them up so they wouldn't come into contact with something conductive. And what looks like soldering resin may be the residue from the adhesive they used. I say that from experience on how solder resin will pool and it doesn't have the look of something like that. I could be wrong, but if there were a pool of resin that large near any kinda of contacts, then the solder points would be horrible and there would be evidence of over heating on the perfboard. The board looks fine and so do the soldering joints. But like everyone else said. Clean it off gently with some isopropyl and I bet it will be fine.

I have some upsetting news. When I removed my graphics card from the EK waterblock there are 4 nuts around the CPU on the waterblock that the PCB attaches to and these have come out of the waterblock with the PCB. They should have remained in the waterblock. There is now 4 pins on one side of the PCB stuck very tightly to screws on the other side of the PCB. EK have a very odd shaped pin that is not compatible with any of my hex nuts so in an attempt to grip the nut with pliers the pliers have slipped and damaged a resistor and crunched one of the memory chips. They card may now be toast, I don't know... Just a week ago my system had a fluid leak and now this, it feels like my life is over.  I will upload a picture of the damage, hopefully someone can assess it...

Really annoyed at EKWB for this. Those 4 securing nuts should never have come out of the waterblock like that.

The resistor is a straight forward replacement for a skilled solderer with the proper basic equipment and magnification, assuming the pads and traces aren't damaged. The memory chip will require BGA rework process with hot air removal, manual solder paste, machine placement and oven reflow, assuming the pads aren't damaged and you can source a memory chip - this is rather expensive as it requires several hours of labor and specialized equipment, with no guarantee of success. I'd recommend trying to sell the card on ebay as damaged to recoup some costs, or maybe evga would be willing to offer you an exchange for damage replacement at reduced cost.

DANG Sad day indeed  All of My EK blocks have standoffs that have flats 180 degrees apart for the use of a small wrench. Those small & short screws are easy to cross thread. Best practice is to spin them CC, till you feel the drop as the threads align, then tighten them gently If they got wet they may have rusted - maybe ? Contact EVGA directly ... if EVGA does Anything ---> Above & Beyond the Warranty Terms its is a GIFT You may just end up sell it for parts or looking for a Third part repair shop
