Average vs peak temperatures while gaming

[Avcn42]

My CPU temperatures reach a max 70C while playing BF1, I expect that to be about 75C in the summer (southern hemisphere), and the average I found on full load through aida64 was 66C on the hottest core. Which is more important? I ask because I have a hard time believing that it's a huge deal when the CPU reaches a certain high temperature for just half a second or less. If it is, why exactly? Also, even though I am paranoid myself currently with my new pc, aren't we all a little bit too concerned about it? I have a notebook that reaches 105C on full load (like watching a video on YouTube, it's pretty old) and never goes lower than 85C on idle. That has been running for a decade (!).

ok thats good 

 

average is more important, because peak temperature doesn't matter because its only a spike once in a while.

The reason there is a difference in those temperatures is the GPU. The GPU will be dumping a lot of hot air into your case which I'm guessing is sent out the top through the h115i heating it up a bit on the way. They are both important in their own way but I would care more about the 66C as if that rises towards 80 then you could be heading towards 90 under cpu and gpu load. Overall those temperatures are perfect and to be expected and completely safe so no worries really

Yes, I really wanted to mount the radiator on the front but unfortunatelly there wasn't enough space, so I have to deal with the GPU heat affecting it. Running aida64 without the GPU stress test gives me a better temperature. However, I don't see that as being the reason for the difference between the average and peak, as the CPU itself is affected indirectly, because what is being heated by the GPU is actually the radiator and therefore the liquid. Once those temperatures have stabilized, those spikes should be the CPUs own "fault".

Temperature spikes have been increased since Intel stopped soldering the IHS to the CPU. The temperature spikes are due to how fast the CPU's run and the rapid changing in the CPU voltage and utilisation and where that utilisation is occurring. Some parts of the CPU produce more heat than others.

Yeah, I thought that made sense, but I just couldn't believe this crap Intel has been doing would affect it to such a degree (no pun intended).
