Sometimes figuring out what sensor is what is tough.  I used to start a
compile of gcc to find out which one was the CPU.  Which ever one went
up pretty good, CPU.  Works for fans too.  Which ever fan spins up
first, most likely the CPU.  I have several that either show very high
temps or very low, a couple would make my deep freezer proud.  I suspect
there is no sensor for those since they never change.  Even some of the
searches turn up different info for the same sensor.  Each mobo is
slightly different I guess.  Just have to figure it out. 

At least gkrellm works.  About the only time my GPU will have any load
on it is when I'm logged into KDE anyway.  I can check gkrellm to find
out if it is staying cool or not.  I might add tho, this case, despite
not having a side fan, is pretty cool even when compiling.  I put a fan
on top that moves a lot of air and I can feel it blowing a lot more than
the OEM fans.  That pulls heat out very well.  The front fans do well
too.  I put one high flow fan on the bottom front and the other two
front fans are OEM.  The OEM fans don't blow as much so I stuck them in
places where less air movement is not a problem.  The CPU runs a fair
bit cooler now.  It tends to max out in the upper 170F area.  Of course
that m.2 stick runs really cool with that cute cooler on it.  I think it
maxes out at around 105F or something. 

If the monitor stand comes in tomorrow and FedEx delivers the monitor,
I'm gonna have a busy day, or night.  I suspect tho the stand will get
stuck at the State USPS hub, like most packages usually do.  I'm gonna
hope tho.  They have improved recently, a little bit anyway.
