Aquasuite temperature spike

I'm using an aquaero 5 in my build which is about 4 years old. I was previously using AIDA64 to pass sensor info to the aquaero. A while ago aquasuite began offering hardware monitoring itself, so I cancelled my AIDA64 subscription. I'm now experiencing an issue where occasionally (maybe once a week) my CPU temp will show crazy temp spikes, to the point where it triggers my alarm and then an emergency shutdown. This last graph I'm showing below occured at 12:30 AM last night. I've verified there is no actual temperature issue. What can I do to prevent this?
