Whereabouts of Lenovo Nerve center !!

So recently I bought a new Lenovo Legion Y520 laptop (refurbished) after much research, hassles, review, budget constraint i settled for this!! So far, I'm very happy with the performance and especially the price at which I got it (40,000 RS approx. 538 dollars) but in several of review videos i saw people using Nerve sense tool for extreme cooling purpose i searched everywhere in various forums but couldn't find this particular software there was this notice that this has been discontinued!! Can anyone elaborate on it why it was discontinued and if it is possible that somehow o can get it??
