Hello,
     with recent kernels after a suspend/resume cycle on my laptop (HP 
6730b) the fans stays at full speed.
I've bisected down to this commit:

ce119f83257aae29b84a5bfad0669e8348437b18 is the first bad commit

     Thermal: Introduce simple arbitrator for setting device cooling state

     This fixes the problem that a cooling device may be referenced by
     by multiple trip points in multiple thermal zones.

     With this patch, we have two stages for updating a thermal zone,
     1. check if a thermal_instance needs to be updated or not
     2. update the cooling device, based on the target cooling state
        of all its instances.

     Note that, currently, the cooling device is set to the deepest
     cooling state required.

I tried to revert it but there are rejects so I cold not try current 
kernel with simply this commit removed.

As a side note when the fan is at full speed a see an anomaly on thermal 
indicator #4

$ grep 0 /sys/devices/virtual/thermal/thermal_zone*/temp
/sys/devices/virtual/thermal/thermal_zone0/temp:59000
/sys/devices/virtual/thermal/thermal_zone1/temp:63000
/sys/devices/virtual/thermal/thermal_zone2/temp:48000
/sys/devices/virtual/thermal/thermal_zone3/temp:27900
/sys/devices/virtual/thermal/thermal_zone4/temp:100000

while the others seem to report normal value. Attached the output of 
dmesg on this laptop.

More info/testing on request.

Kind regards
