(2018-12-16: EDITED THREAD TITLE) Not long ago I bought a performance laptop. In the past I always used my desktop for such applications; I had cheap laptops just for basic internet access. This one has a decent video card; and I've found that these types of laptops are notoriously difficult to cool. Unlike for a desktop, you can't just buy and install a 3rd-party cooling solution. I bought a laptop cooler and, as quality as it is, it really makes little-to-no impact on thermals. But I found a solution so I thought I would share it. I have had experience overclocking for over a decade, but I had never really heard of "under" clocking; specifically, under-volting. To make a long story short, if you have never heard of it, check out a program called Intel Xtreme Tuning Utility...Or Intel XTU. There are many versions and each one is specific to certain CPU or chipsets. So, you might have to try several versions before you find one that works on your computer. For years this app has been branded and included on the driver CDs of most high-end video cards. It has it's flaws; for example, you might have to run it every time you turn the computer on. The software, though powerful, can be used by any novice. There are good videos on Youtube on how to use it, so don't be intimidated. At any rate, after much testing I was able to get a stable under clock and drop my temps by at least 10 degrees under full CPU load. No more thermal throttling...no more maxed-out fans sounding like jet engines. No hardware needed. And it's free. And the monitoring (graphing) capabilities of the program are stupendous. Actually, I am amazed that I was able to accomplish this with a piece of software. I thought I would share my experience.
