I have a laptop that came with an Intel i7-4700mq cpu in it, the processor was starting to run hot during gaming sessions(90+ Celsius) so I decided to pop it open and re-apply the thermal paste.

After pulling off the heat-sink I found it completely covered in huge chunks of thermal paste and the contact point on the back of the CPU itself had paste all around it and spread into the two rows of metal contacts next to it.

This was before I cleaned off the excessive amount of paste, but you can see where it has been spread into the contacts.

I was curious what these metal contacts on the backside of the CPU are for, and if the paste having spread into them is likely to cause issue. Had it been on the main pins connecting to the motherboard I would be much more concerned. I cleaned as much as I could using a coffee filter, but not having much luck getting the paste out from between the contacts. Appears to have hardened a bit over time.

Usually those are pass throughs to the other side of the PCB and/or small capacitors and resistor sets. Hard to tell with the goop on it.

Something like a cotton Q-tip would should let you get that out of there. That is non-conductive thermal compound most likely so I doubt it would be causing any shorts.

It's probably non conductive paste, so the pin contact isn't much of an issue. I also dont believe it was causing your heat issue. Laptops in general get very hot.

Thank you both! It's been on there for a while, so I figured if it was going to cause issues it probably would have by now. Just wanted to be sure before I decided if it was worth the effort to try and clean it.

PsyKhiqZero, Yeah, all of my laptop have run hot for gaming, it's just part of the deal. This one specifically though had decent airflow and was using an external fan and still hitting 95 degrees some nights. Since I re-applied I haven't gone above 82 degrees, which is a huge improvement. I don't generally care all that much until my CPU's go above 90 on laptops. May have been a poorly positioning heat-sink on top of that lovely paste job too.

I've had shocking results changing out the paste even on non-gaming laptops. Not sure what sort of quality control they run, but way too much seems to be the norm. (Might be a case of "if they don't see any paste gooping out at the edges they don't think it was done at all")
