Dell Fan Monitoring
#1
For the last month I have been running down reasons why my fan is very active.  
After Malwarebytes, virus checks & Dell Diagnostics.  Windows now updates, a virus/trojan has been eliminated.  Now the fan is much better behaved, mostly idling.  
My last 'rundown' is Chrome Browser which seems to suck up cpu to 75%, keeps MsMpSvc also at a high level and the fan intermittently works hard.
I googled HwInfo and, I understand there is a Dell fan monitoring problem that may be enabled by using the Dell interface.  I haven't been able to work out if my Dell will report fan speeds (I don't want to control them).
Please can I be advised if HwInfo will report my Dell fan speeds?
I report; enabling EC in HwInfo results in BSOD, on earlier version HwInfo, wakeup after hibernate, HwInfo kept 50% cpu and could only be stopped by reboot.

Thank you and regards

You will need to enable EC Support in HWiNFO in order to see if it's possible to report fan speeds on your machine.
If there are problems with this mode, please attach the HWiNFO Debug File from the crash for analysis.

I re-enabled EC; CPU & GPU temperature was reported (different from the main body of the sensor report) then a report of the fan displayed at 3,300 rpm, even though I did not notice any change in fan speed.  Then mouse froze (AltTab as well).  Powered off, held for 20secs for leak, powered up.
Launched HwInfo, enabled EC, displayed sensors with EC; CPU, GPU, fan with red cross.  Right click enable all.  Displayed '-' all three for approx 5 secs, then displayed the 2 temps and fan speed 3,100 rpm, no audible change in fan speed, maybe 15 secs, screen flickered a couple of times, then BSOD and restarted.
Not sure about the timestamp on the file.
Thank you and regards

Please try to remove the battery from notebook if possible and see if then you can run with EC Support enabled.
Another option might be to try to disable the battery sensor in HWiNFO sensors list.

1. Launched HwInfo, disabled 3 battery traces, 3 red crosses changed to enabled, CPU, GPU & fan trace '-' for about 5 secs and then displayed temps & speed maybe 15 secs, BSOD.
2. Removed battery, launched HwInfo, enabled EC, 3 red crosses changed to enabled, CPU, GPU & fan trace '-' for about 5 secs and then displayed temps & speed maybe 15 secs, BSOD.

Meandered through Google, found reference to monitoring fan speeds using Intel Extreme Tuning Utility, downloaded and it failed to install.  Meandered Google more... .
Thank you and regards

I noticed you're using a bit older version of HWiNFO. Can you try the latest one ?

1. Deleted current HwInfo download zip, program file.
2. Download HWiNFO32 Beta 2830, extract to program files, launched HwInfo.  Battery has been re-installed.  Report; displayed Dell EC red cross, Battery 3 red cross.
3. Closed HwInfo.  Launched HwInfo.  Settings; ticked flag EC.  
Launched Sensors.  Sorry, forgot, fan runs at full speed 2 secs, sensors report displayed. 
Report; displayed Dell EC red cross, Battery 3 red cross.  
EC Red cross, right click, enable monitoring, after approx 2 secs, GPU temp displayed, fan displayed 0.  
Screen flickered at 1 sec intervals approx 4 times, BSOD.

Thank you and regards

So with "EC Support" enabled you see the "DELL EC" sensor, not a "Compal EC" ?

Last night, I had tried some testing sequence like this and BSOD a couple of times.  Decided I had not been focussed enough so tried harder this am.

Please ask for anything else I can provide and/or, set out test and reporting procedure.
Thank you and regards.
ps Now going to run RKill, Malwarebytes, MS Antimalware, f-Secure & long scan MSE.
