Using HWINFO

Just thought I'd share my experience of the last few days. I built myself a new PC which I am very happy with, Ryzen 7 2700X, 16Gb etc... Anyway its very good and as you will understand I have been monitoring it with HWINFO, thats sensible. Day 2 and the fans constantly spinning up and down every 3 seconds irritated me a bit so I set a custom fan curve, thats that sorted. But I was a little inquisitive as to what the cause was. At idle the HWinfo CPU temp graph looked like a saw blade, sharp up and slowly down, sharp up and...ad infinitum. I spent a couple of hours with task manager and permon but they don't have the granularity to really nail down the cause. In the end a search on the tutorials on here led me to Performance recorder + analyser. Now they are good tools!
So after a good day wasted I now know what caused the regular 3 second spikes in my HWINFO graph....you guessed, it was HWINFO set to poll every 3 seconds! All this because one of the fan boundaries was set 1c above idle.

Hi,
I believe the polling default is 2000 ms if that translates to 3 seconds I don't know nor have I noticed anything odd using it
I'm usually pushing pretty hard and with fans at 100% when doing so
I imagine that is why I haven't noticed

Best free tool out there hwmonitor is okay too but not near as many goodies in it.

Yeah I had it set to 3000ms. I didn't need to do any of it, I just wondered why idle temp was fluctuating between 35-40c. Anyway I've simplified the post quite a bit. Actually it was atikmdag.sys causing the spikes but somehow triggered by HWINFO sensors. I did try different drivers for the radeon but they all had the same effect. It is only my OCD type illness that wants a smooth flat line graph but now that I've investigated I can live with it!
