Disadvantages of Undervolting + Rant

[LordsK]

I have an HP Omen Laptop which is about a year and half old.. I was complaining at the very beginning for the temperature issues, but was not heard by anybody. So, I just thought that 90+ is just normal for a laptop temp and just didn't bother. But after a year, my battery got bloated. Though there are numerous reasons why this could happen like overcharging or just simply defective, the current temp my laptop emits could also be the culprit..

Then I kept searching because HP hasn't been so helpful with any of my queries, let alone the battery issue. Then as I kept searching, I found out about Intel's Extreme Utility and undervolting. I thought at first that it will drop my performance, only to find out that it didn't and somehow stabilized it! My temps decrease for up to 10 deg, maxing it only to 90 but not beyond. Before I was reaching 98 on my temp counter in game! I checked my fans + cleaned it (that's how I found out about my battery that got swollen). On idle, my cpu temp is only about 55-65.. So, yes, it has to be the games that I play, but duh! This is a gaming laptop, so it defeats the purpose of getting this if I'm not going to play with it. Well, it seems that my temp issue is gone for now, but what I don't understand is why this kind of legit programs were not introduced to us? I mean, we are using Intel cpu which is known to spike temp, but was not introduced to some great solutions like undervolting? I believe this app should have been added to us by default! Instead we have this HP support assistant app that says my battery is good and still don't need to be changed, but when opened, it's already bloated as fck!

Well, I'm giving my 2 cents to try once more to ask some query because as I search, I still couldn't get some facts. What's the negative impact of undervolting this time? What I mean about undervolting is undervolting it in moderation, I don't know the term, but lets just say optimal?

Undervolting can make your system unstable, But you have to really push it to get that way...

If you do it step by step and test each time you can undervolt to the limit of stability..

The reason why it might become stable is because you are removing working voltage from the CPU, the problem is INTEL/HP always overvolt their CPUs since there is a manufacturing threshold in which each CPU might require a different voltage to work on..  What we are doing is removing the excess voltage that becomes excess heat.. 

System might become unstable when you remove too much voltage for the CPU to run normally, In which the only problem might be that the system Freezes, Since INTEL XTU is working on a software level you just hard reset the Laptop (Holding the power button for +5s) and XTU will remove the undervolt by itself next time the laptop boot up so there is no possible damage done to the Laptop.

So in resume, There are NO DISADVANTAGES to UNDERVOLT if done right.

It's pretty stable at -0.05, well actually beyond, but i start noticing lags on games at -0.075 so i stayed at 0.05.. Scraped about 5-7 deg celsius on avg temp, but i still hit 90s, 92 at maxed.. I dont know if vacuum fan is a good idea, but at the least, it seems like the necessary evil for me. I dont want my fans to get damaged too. Though it seems i have no choice.
