As you can see, there’s still a blackness to it I’m unable to remove. Possible burn mark?

Hi - Sorry for the delay have been working on my own computer.
Could be a burn mark - Hard to say by photo. To me it looks ok. It looks like it is a RS 485 chip
Does the fan work?
Paste is a touch heavy but should be good.

The main thing does the fan spin

OH MY GOD!!!!

It’s a miracle against all odds! I honestly did not expect the replacement fans to work, but work THEY DO!!!

Thanks a billion for your invaluable help, @PeterOz. Fans are spinning, and I’m getting delightful idle temps at in the high 30- low 50 degrees Celsius range. Can’t wait to benchmark the heavy stuff.

I‘m so happy right now. This ordeal is finally over after weeks of issues (and I don’t have to buy a new computer!) I really appreciate your support through all this, thanks again!

Before the mods close this thread, however, I’d like to ask another question.

I notice on my Predator Sense that once the cpu/gpu reaches a certain threshold (i.e. the temps are < 40 degrees or something) it ignores my custom fan speeds and just turns off. Setting them to max manually still works, but that is too loud. Rather than let the laptop warm up and then the fans kick in, I’d rather they keep the computer cool and spin at a reasonable volume (less than max). Would there be a way to override this cutoff, or is it hardwired/requires BIOS editing? Am I better off just leaving it as is?

Update: It appears that one of my RAM sticks is not recognized by Windows. I’m going to try reinstalling them, but it’s real late now so I’ll do that tomorrow.

Yeah, taking out and putting the RAM back in did the trick. Windows recognizes it correctly now.

@PeterOz Yeah that’s probably what it’s doing. Yes, they do turn on once it gets hotter, I was just asking for better control of my device. It’s not really a problem, since under gaming it’s not likely to be anywhere near that cool anyway for fans not to spin. And I’d probably set it to max myself under heavy loads.
