I was playing a game last night when my computer warned me that my GPU was overheating. I have a G10CE pre-built PC, which is known for its poor airflow. I opened up my computer and found that the GPU fan wasn't spinning. This seems to be a common issue with the 12GB 3060 series. I decided to try and fix the fan, and while looking for solutions, I came across suggestions to replace it for about $15. Instead, I thought I'd try lubricating it since I read that it's possible with silicone-based lube. I didn't have any, so I used dry lube intended for saws, even though I know it can be risky regarding conductivity. After reassembling everything, the fan worked, no smoke, no obvious short circuits, but now I have no display on my monitor. I've reseated the RAM and GPU and tried using HDMI cables instead of DisplayPorts, but nothing worked. Is there a chance I can fix this, or do I need a new GPU? Also, if the GPU is dead, I was considering the 5070—would that work with my i5 11400F?

That's strange—everything seems to work fine except for the display, right? Are you sure your monitors are all functioning?
Common sense question here: how do you think the lubed fan is going to behave when it starts spinning? That lube could get flung onto nearby components, and with those chances of it being conductive, you might have just sprayed some liquid all over your motherboard and power supply, right? Double-check all the connections you undid for the fan just to be sure!
You really made my day with this story! But look on the bright side—you saved $15 by trying to fix the fan yourself!
How much lube did you apply? If too much leaked through the heatsink to the PCB, it could cause issues, but usually, a dying fan shouldn't fry the GPU. Make sure everything is plugged in correctly. Can you try booting using the onboard GPU and check if the card shows up in Device Manager? That could give you a clue!
I disconnected the fan and soaked up any excess lube I could, but now I'm thinking it might've been a mistake. Maybe I just need a new GPU anyway.
It's dry lube, so it shouldn't fling around!
