I've had my Helios 500 for around six months now and it hasn't missed a beat. Thanks to help from @Red-Sand
I was able to get temps down by undervolting the MAX profile in PredatorSense by 0.145v and I now boot with that profile.
I was able to run the Intel XTU CPU stress test for an hour and get peak temps of 75c with CPU rock soild @ 3.9Ghz on all cores. Looking at Windows 10's Performance Monitor I could see all six cores were running at 100% the entire time.
All of my gaming was around the same temps.
Recently I've been using some flight simulator software and just changed from Microsoft Flight Simulator X (FSX) over to Prepare3d version 4 (P3Dv4). I changed because to P3Dv4, a 64bit program because FSX was 32bit and was prone to running out of Virtual Address Space and crashing due to Out Of Memory errors. Both FSX and P3D are very CPU heavy but P3Dv4 is 64bit and seems to do a much better job of utilising all cores on the CPU, plus it does a better job of utilising the GPU.
Since I've been using P3Dv4 I've noticed CPU temps spiking getting into the high 90's at times. Everything runs fine and if I hadn't been monitoring temps I wouldn't know the difference.
My Question is why the differences in temps between XTU and P3Dv4.Intel XTU
and some other synthetic tools with a 60-minute stress test - runs all six cores (12 threads) at 100% with temps spiking in the mid 70s (as reported by XTU average temp in mid 60's / average CPU usage 99% / average clock speed 3.88Ghz)P3Dv4
use forn an hour - all threads in use with temp peaks in mid 90's (XTU reports average temp 82c / av CPU usage 80% / Av clock 3.87Ghz)
All tests were done with system temp, as reported by PredatorSense, at around 40-42c with fans on high.
Both programs are running all cores/threads at 100%, yet P3Dv4 leads to much higher temps.
Any ideas why?
