Is my notebook fan dead? zt3000

I have an HP zt3000, about 2 years old. Right now its hitting 71C
degrees sometimes 72 at 45% cpu util for 60 seconds. Its idling at 64C
degrees, which seems kinda high for sitting idle. It also seems kinda
hotter on my lap then I remember before.

I have this feeling that one of the fans is not working. I can't hear
a fan coming on and it used to be that at this kind of use I would hear
it click on. However there is a hole on the bottom that looks like a
fan hole. I look in there and I can't see a fan spinning but I can
feel a tiny bit of air coming out..very slight...and I can hear a fan
inside if I put it up to my ear. I'm guessing that this is the CPU
fan..but I don't know how notebooks work. Do they have both a chassis
and cpu fan?


In any case, my notebook is still under 3 year extended warranty with
Best Buy...but I want to make sure its really defective before I go
through the hassle of giving them my laptop for an extended period to
fix it.


How can I find out if the fan is working? I tried to install Hmonitor
to try it out. It shows me the CPU and HDD temps, but does not
register any fan readings. Maybe someone knows a better util that is
compatible with this notebook?


What is considered a normal range of temperature and how can I tell if
the fan has stopped working?


I also already checked the BIOS to make sure that the fan is enabled
for always on with AC power. Made no difference.


Any tips would be greatly appeciated. There used to be a web forum for
this notebook, but it appears to have dissappeared, I can't find it
anymore sadly.


Thanks in advance.

 

I say open it up and clean the dust from the vents. Two years is a long period especially if you haven't cleaned the laptop at all. Here are HP's manuals for your notebook.
By any standards, 64*C is very high temperature for idle mode.
