so I'm playing games on my PC and I have some fan control setup using SpeedFan for my PWM fans which usually works really nice. However, the other day my game wasn't running so smoothly and I saw that my temperatures are quite high. I opened up my SpeedFan and saw that it's not detecting the fans or any temperatures. I restarted it and it showed the following output:

After the restart, it detects only the GPU fan and all the temperatures normally, but none of the other fans. Not their speeds or anything.
I opened up Aida64 which successfully detects everything, including the fans.
After I restart my computer, SpeedFan starts up and detects everything normally and works again normally for a while. However, after some time, the same thing happens.
What is it that is causing SpeedFan to stop detecting controllers and sensors while gaming?
EDIT 26-Jun-2018: Here's the output after I restart the PC and it successfully detects everything.

You should report this as a bug. It's not a question we can answer for you. – DavidPostill – 2018-06-26T17:38:16.967
1Well that's funny, because before you put it on hold and almost deprived me of seeing the answer and solving my issue, I managed to see the very first answer which got the issue 100% spot on. So I guess it's not too broad for the people this is meant for.
And also, just because something is failing, doesn't mean it's buggy or that the failure is caused by the thing that's failing. This could have helped all the people who will be Googling this issue. And I know they will because this is a common problem caused by a game with 2 million concurrent players. I guess now they will never know. – Sam – 2018-06-26T17:51:51.960
Hey Sam, I was going to improve the answer and ask you which game this was about. I saw this is a thing in ARK and PUGB. I'm not sure what other games use battleeye, so I was hoping to get more info from you. The answer that was deleted was spot on, it just needed a bit more detail that I was going to add to. – DrZoo – 2018-06-26T18:00:37.327
Yeah, it was PUBG after all. I'm actually quite concerned now, this seems like a massive security issue. It's very intrusive, I never allowed a game the power to decide what software I may and may not run on my own computer. Not to mention it could have caused hardware damage. – Sam – 2018-06-26T18:12:37.873
I've reopened it for you. It's still, however, a poor question and you should still report it as a bug. – DavidPostill – 2018-06-26T18:15:12.167
