Installed new i9-10900K processor into new ASUS ROG MAXIMUS XII APEX Z490 motherboard and immediately after I finish putting everything together (prior to first attempt to boot) I notice a significant amount of oily staining between the extended VRM heatsinks around the LGA socket... Attempted to clean with 99% isopropyl alcohol the best I could and I succeeded in removing most of it, but I didn't have time to remove the heatsink itself and examine closely yet because I needed to get back to work. As best I could tell from inspecting the front of the board I didn't notice any bulging or leaking capacitors, but I can't be sure with the heatsinks obstructing my view. So far everything is OK and I see nothing obviously wrong Windows 10 installed and PC behaves normally so far. Should I be more or less worried? Any insights into what this is? Electrolyte fluid, oil from a thermal pad, excess flux? Gonna remove the heatsinks when I have time, but wondering if I am putting other components at serious risk... ?

My guess would be Thermal pad drainage. Like you said, you won't know until you are able to visualize the area in question.

Is that where the heatpipe is? It could be leftover solder flux.

Yes it's the center that is stained and evidently where the gaspipe lies situated between the top & bottom aluminum slabs. The oily residue trails around the connected VRM heatsink visible on both the top and left side surrounding the LGA socket

Had some oily/sticky residue coming off the heatsink/vrm area onto/around the CPU socket, that I bought four months ago;

Doesn't affect the operation but I do expect it to fail soon, because it's just how it goes with PC Hardware bought on the cheap :thumb: .

Hi,
More likely silicone asus uses that to glue the heat pipe inside heat sink and just got a little too much
Found out it's some tough stuff too when I tried to remove the pipe on my x299 vrm so I could still use the aio cover and vrm water block.

This is the conclusion I arrived at myself after I reluctantly disassembled my rig and examined the board closely from multiple different angles with proper lighting. I can see the substance applied specifically above, below, and behind the VRM gaspipe in between the top & bottom aluminum heatsinks yet I do not detect it elsewhere on the board and it seems to be applied intentionally, which gives me good reason to believe it's just a harmless adhesive applied a bit too liberally during production as you say.

Hi,
Yep and board was stacked in a way it oozed out
ASUS is so picky about board condition on rma not sure I would keep it :/

Seriously? Are you implying it could be denied RMA request for their manufacturing error?

Hi,
ASUS likely would blame you somehow
Just a scratch they've been know to reject rma's.
