Why are laptop CPU's so shiny?

post #1 of 7
Thread Starter 
I was re-pasting my laptop with an i5-2410m the other day and when I cleaned off the stock paste the CPU was like a mirror. It was literally just as shiny as a mirror. Only difference was that the metal part that covers the actual CPU component was small, and you could see the green PCB of the CPU, unlike modern CPU's.

So why do they make them so shiny? I mean, it's not like people walk around comparing how shiny their laptop CPU's are.

Might not have the metal IHS (like older gpus), laptops are generally taken apart less & no IHS would give a bit better cooling.

There isn't an IHS installed on most laptop CPU's IIRC, so that is the actual chip of the CPU that you are looking at, not a metal shield.

Probably a different metal. Something more durable and high-quality. Mobile CPUs are usually more durable against heat(hence why they are usually good at overclocking) so it'd only make sense.

I honestly have no idea though.

No IHS. i actually took mine apart the other day and also noticed this...
You can remove the IHS of desktop CPU's too but it isnt reccommended

Yeah as said they have no Heat spreader. Be careful repasting. Too much pressure might crack you precious mobile cpu.

Also keep in mind that since there is no IHS, electrically conductive TIM can damage the processor the way it can with a gpu. Always use non conductive TIM when working with a chip that doesn't have an IHS, where there is other circuitry exposed.
