Why do laptop CPU's not have lids on them.

post #1 of 7
Thread Starter 
Lots of delidding going on for ivy bridge. If intel doesnt want to do high quality internal TIM why does it even bother putting al id on its CPU's? Why not just leave the lid off like they do on laptop processors. It would make cooling more effective, and would cut costs for the company.

I remember hearing years back that one reason most CPUs have an IHS is to protect it from damage from large CPU coolers. I don't know if this is totally true though - just passing along.

well ive seen multiple people do an unlidded ivy bridge mount. They remove the retention bracket and hold the CPU on with the cooler. ive seen it done with a hyper 212 and multiple water cooling blocks.

Because the VAST majority of users will never open up their laptops, and the laptop coolers can be installed at the factory. CPU's are very vulnerable without their IHS and they can be easily damaged. By only delidding laptop CPU's, Intel insures that temperatures (a perennial problem for laptops) are kept in check and that only professionals at the factory install them.

In short, it keeps em cooler but more fragile which isn't a problem if it's professionally installed.

Well whats stopping intel from selling a delidded version of their CPUs for overclockers?

For the same reason coachmark2 said. If you delid and put a heatsink on tight you could damage the chip. Not sure the chip itself would withstand the pressure of a tightened heatsink without crushing it.

People would kill the chip accidentally then RMA it. Also I don't think extreme overclocking is a large enough target.
