Yeah I should had emphasized more about it, mining on laptop will kill it in most cases, sooner or later. just get a specialised mining rig, like a desktop with 1-3 GPUs (since you don't have huge budget, but if you do at least have enough for that and you are interested, it'd be fun) its much more easier to cool, for example you could take cover panel off and it will cool more efficiently - ugly but effective from what I've heard. Or you could just build it inside a metal frame or whatever like some more dedicated people do, its more effective than having closed case I think, and in case of laptop thats just worse.
Gotta ask about those metal frames around here soon, I am wondering how they build it or where they buy it
