mine on the gigabyte ga8ik1100 only runs (as far as I can tell) during power
up/down. I never see it run at any other time.
Is this normal?
cpu temps run around 41c so that area isn't to hot, but no idea what
northbridge temps run.
I am concerned it is not running as often as it should but have no info to
back that up.
Thanks
 
it should probably be running all the time when the computer is on, maybe
something wrong with the fan or the connector on the motherboard. good news
is the northbridge doesnt really need a fan, bad news is since yours came
with one the heatsink probably isnt adequate for use without a fan. you
could just replace it with a northbridge heatsink thats meant to be used
without a fan, zalman makes one.

I replaced my northbridge fan with a zalman passive heatsink on my
ga-7va motherboard within the first week. northbridge fans are icky.

the confusing thing is that it does run on startup and power down, but I see
no evidence of it running besides that.
I will look into the heatsink issue.
 
Since it starts then stops, I would say it is on a temp sensor and doesn't
turn on until it gets too hot. Question is, where is the sensor for that
fan? If you are concerned, get a diff fan. I have seen them at Comp USA.

A temp sensor would run it at a lower rpm, not stop it.

I was just wondering about that. I do not know where sensor is, I think its
built into board. I also think my sight might have been skewed so I need to
really double check this. I might be wrong about it and might be worried
about nothing.
 
was this easy to install?

The most difficult part was getting the heat sink that came with the
board off of the northbridge. It's attached (mine was, at least) with
very sticky double sided tape. Once that was removed, I just followed
the directions from Zalmann. The tape ripped a bit, but it all came off
attached to the heat sink, so there was not much cleaning on the north
bridge except a little wipe down with an alcohol swab. The Zlaman pins
were slightly fidly, but as long as you pay careful attention to the
details in the instructions, the installation will go perfectly in under
ten minutes.

crank the machine up by running a 3d benchmark or a burn in program. take the side cover off and check the fan

Smart Fan I think this is what controls the bridge fan.

Multi Language BIOS
 
Gigabyte m/b? Have you by any chance installed EasyTune4 off the Gigabyte
driver & utility CD? (EasyTune is the "overclocking" utility with a GUI
that looks like a game console designed by a hyperactive 8-yr old...)

By default, EasyTune4 will only run the Northbridge fan between 09:00 &
17:00.... That is why you see the fan running on startup & shutdown, as it
is either before ET4 starts or after it is closed. You can't disable this
"function" either - the best you can do is set it so that the start time is
1 min. after the stop time. Better is to uninstall / not install EasyTune,
& use MBM5 to monitor CPU temps.

At least your NB fan is in compliance with the European Working Time
Directive...
