[RMA] What is this lump on my friend's CPU?
(lemmy.ml)
EDIT: We decided not to pursue further diagnosis, because we wouldn’t know what the hell we’re doing anyway, and decided to start the RMA process instead. It might not even be the reason why the PC won’t turn on, but I’m not comfortable with putting that CPU back into his PC again. Once we get a replacement, we’ll see what happens. If it’s still busted, we’ll just take it to a local shop. Thank you everyone for your for your suggestions and insight, they are very much appreciated.
My friend called me to take a look at his PC that wouldn’t turn on. Upon inspecting his CPU, I noticed a silver bump at the bottom. I’ve never seen this. Can anyone tell me what it is?
That's not it. Even if the overheating melted something in there, it wouldn't just ooze out to some spot and form a neat blob without a trace.
The photo is almost identical to one shown in one of the GN videos. Gonna be a bad internet denizen today though and ask that you take my word, because I really can't be arsed to try to look up specific videos and times.
If you don't take my word, thats completely understandable, but as I said, cannot be arsed with looking it up, so I'll just accept that you don't believe me.
That's fair. Though I still do believe you since everything you said seems completely plausible. I'm skimming through GN's videos right now, but there are loooooads. Hopefully I'll find it eventually, because I really am curious. In any case, my friend and I decided to start the RMA process as suggested in your other comment, because if nothing else, the CPU looks really dodgy. Thank you for your time and insight!
Yes it would. That's exactly how solder would bahave in this case. The fact that you call what is obviously solder... "something"... means you don't know what you're talking about.
It could actually, the Heat spreader is usually bonded to the Chip with some form of Indium Solder, which usually has a melting point of up to 210°C (most compositions are around 120-140°C).
Solder likes to form a similar ball around traces and components, since the solder does not stick to the silk screen of the PCB.
And I remember that this is exactly what happened in the Gamer Nexus video, the Indium Solder was melting due to Overheating.
