How do I find out how hot my car engine is?
Hi everyone, I am using MSI Afterburner to try and get more FPS for CS GO on my GeForce 635M. (I know I shouldn't overclock laptop GPUs, but someone has done it before.) The issue is that when I raise the Core Clock between 70-85 degrees C (85 gets hot enough during games), the core clock drops down to 662 Mhz (which is the base speed of the GPU). But the memory clock stays the same. So, I think this means I am getting thermal throttling that slows things down. Question: How do I find out exactly when it starts getting too hot? The in-game monitoring from MSI Afterburner isn't super precise, so it's hard to tell because there is a small delay between when the temperature goes up and when the clock speed drops. Thanks so much in advance.
There is always a delay. It cannot be avoided. Intel checks how hot their CPU gets every 256 milliseconds, which equals four times per second. If you tried to read those exact temperatures right away, it would look like just the number '88', nothing but a blur. So there is a natural pause of a few seconds between when the temp is checked and when it shows up on your screen. Just so you can see that moment clearly. Only if you graph it will you get everything shown, but this gets confusing with multiple cores because the reported temperature is usually just for the hottest one, which changes depending on what you are doing. Because of how the silicon is made and all the tiny impurities inside, you will inevitably end up with some cores that are stronger and others that are weaker, along with a few that have different traits. So while one core might slow down at one temperature...

This means there is naturally a small pause of several seconds between a polled temperature and the next one that gets reported. Just to make it easy for you to watch it happen. Only if you graph the data will you see everything, and even then it can get confusing because with multiple cores, the reported temp is usually just the hottest core, which often changes depending on what you are doing. Because of how the silicon is made and all those impurities inside it, your cores will naturally be some stronger than others or have slightly different features. So while one core might slow down at a certain temperature, another core might throttle at a slightly higher or lower temperature. I do not think there is an exact measurement for exactly what total temp the whole cpu will start to throttle on. Intel says they guarantee it throttles around Tjunction, but that's just my guess and could be wrong; however, you can be sure it will throttle near that mark. How nvidia calculates its own throttle temp is a complete mystery to me, but I think they probably do something similar to intel since the chips come from the same maker. But keeping your gpu temps below 80 degrees is much safer and better for you. It makes getting high fps in csgo very easy, even when it exceeds refresh rates. There is really no real advantage to trying that on a gpu because you would only see maybe 5 to 10 fps gains at most depending on which version of the 635M chip you have, and there are four or five different versions just like that. That's not much of a difference and it won't affect your gaming at all.
