View Full Version : Absurdly high CPU temperatures when playing some games

So I've been replaying RAGE recently and I've noticed that when I'm playing, the CPU temperature reaches as high as 98 C at some points. As a result, I took my computer in to the shop in order to get the thermal paste repasted, but even then, the temperature is quite high. I had my CPU overclocked at the time, but even when I reduce the overclock to stock settings and then offset the voltage to -57 (the furthest I can go that's stable), I'm still getting above 90 C temperature at times. Granted, the thermal throttling generally immediately kicks in and reduces the temperature, but I'd rather it not hit those temperatures in the first place. What could possibly be the problem? Is my fan dying?

EDIT: I have an ASUS G750JW. I do overclock my GPU, but the temperature never rises above 60 for my GPU, even with a relatively high overclock.

EDIT 2: If I just left the computer as is and just let the thermal throttling do its thing, will it hurt my computer? I've noticed that this particular game can run at clock speeds below even stock options without much trouble, especially with GPU Transcoding, so I'm baffled as to why it takes so much CPU power in the first place. I know it's tied to MaxPPF (turned it down from 64 to 16 because 64 was far too big of a load on the CPU) but I don't know how to really mitigate it after bumping it down to 16.

EDIT 3: I tried messing around with the Processor Power Management setting on my Power settings. Changing the maximum processor state from 100% to 99% dropped the processor frequency from 3.4 GHz to 2.4 GHz and I could run the game almost without issue and the temperature would only reach the high 60s or so. Why does this happen? Why does dropping a single percentage knock down the GHz so much? The reduced GHz seemed to have solved the temperature problem for RAGE, but I didn't get a powerful CPU to have its clock speed reduced that much. Any suggestions?

EDIT 4: Okay, I figured out that the drop to 99% being so huge is because I turned off Turbo Boost doing so. Apparently, Turbo Boost increases the clock speed immensely but also makes the CPU burn up. However, I read from some people that I don't need to worry about temperature with Turbo Boost on, as if the temperature hits a certain threshold, it'll automatically underclock it down to prevent the temperature from hurting the CPU. However, that sounds like a load of BS, but I want to know if that is true. If it is, I guess I can just leave my computer as is and let the CPU throttle itself when necessary, but I'd still like to know exactly how to proceed.

It may be bad paste job or bad thermal paste. Also you should check may be something is blocking air holes in your laptop. The environment temperature may cause overheat. What is a temperature in your room?

I've noticed that my laptop was a lot cooler in my basement when I moved it there (due to the basement room being much cooler), so that might be a reason why it's burning so much. However, I'm not sure how much of an effect it actually has.

Also, what are the consequences of the temperatures being constantly this high? If the thermal throttling does its job, do I need to be worried?
