My new laptops come with the gtx 860m and I've been thinking about a cheeky superclock on the thing but a lot people say upping the clock speeds will increase heat and kill it, now I'm under the impression that increasing voltage is what up's the heat (I'm not touching voltage only clock speeds). So basically, are my thoughts correct or not?

Thanks I'm advance :D

overclocking without overvolting will still increase temps and maybe power consumption and cannot be recommended! it clearly depend on your hardware implementation! even some gaming laptops with high end gpu and cooling struggle to maintain good temps at stock speed. if you are so eager to try some, make sure you explore first your hardwares thermal performance at stock setting under extended period of time first! another thing you should consider is that laptop power adapters are designed for specific power consumptions and may fail to deliver power at higher demands.!
 
Both increase heat output, and "a lot of people" are half right; heat output will rise, but it will not "kill" it unless you let the thermal activity get out of hand. If you're going to go through with overclocking, a rule of thumb is to increase the clock in small increments (baby steps) and then run stress tests. Stress tests like Furmark put unrealistic stress on the GPU, so if the chips holds up to such a test and maintains decent temps, you can leave it there or give it another small bump, then test again.

Note that I do not promote nor decry overclocking nor overvolting. Both are liable to cause instability, and in more extreme cases, both are liable to damage the hardware.
