Enabling the Q-fan

I'm wondering whether I should enable the Q-Fan in my P4P800 mb's bios? I
have chosen not to upgrade my bios because the benefits are minimal...no
sense taking chances....anyway, my cpu temp is 92 f mb is 93......what are
the benefits of enabling the q-fan...? disadvantages? Any thoughts are
appreciated
 
I enabled qfan with my a7n8x-dlx for a spell, but became concerned
when I never saw the CPU fan speed increase, thus, it appears the temp
activation levels for qfan are a bit high versus typical operating
temps. Qfan would be great if you could also select the temp switch
point at which the CPU fan would be rev'ed up.

You are so right! I have a K8V and it runs at 45C with q-fan disabled
and 51C with it on. It does adjust the fan speed on my board (it
dropped way down until the cpu heated up and then sped up to stop the
heating at 51C), but if it's going to let it heat up like that, it's
useless to me.

The hurrider I goes the behinder I gets; which makes sense because
the older I gets the more behind I gets. And I is gettin an old behind!
 
Q-Fan seems to only set the fan to full speed when it sees a CPU temp of
50C or more, at lower temps it runs at the ratio you set it to in the
BIOS.

What sucks about qfan on my A7N8X v2.0 is, it's reading the CPU temp
from the socket and not the CPU die temp, so when qfan kicks in the
socket is at 50C but my CPU temp is already at 62C, would have been nice
if they had a temp setting for q-fan., I ended up turning q-fan off and
put a variable speed fan on my heatsink.

If you are using the stock Intel heatsink, don't enable Q-Fan - the Intel
heatsink/fan has built-in thermal speed control, and enabling Q-Fan may
conflict with this.

Basically, with a non-thermal-controlled fan, Q-Fan allows the fan to run at
lower speeds when the CPU temperature is lower.

Stop telling people this! It's ****ing BULLSHIT!

Q-Fan works superbly and stops the Intel fan from working harder than it
logically should.
 
I have several P4T533's and P4T533-C's. The -C does not have this
feature and I truly miss it. These machines have Intel factory COPPER
heatsinks (the ones shipped with the retail 3.06 and 3.2 GHz CPUs with
Hyperthreading, and very different from the aluminum fans shipped by
Intel with the slower P4's and Celerons). While this is a much better
heatsink, it has a faster, more powerful -- and noisier -- fan. The
difference in sound level is very, very substantial, and from a cooling
perspective, the Q-Fan feature seems to work almost perfectly, keeping
the fan slow and quiet almost all of the time, but bringing right on up
to full speed if needed (it's interesting to start a DVD encode and
listen to the system running the fan throttle right up to the firewall!!)

The difference in noise level is so dramatic that we are actually
replacing the P4T533-C's with P4T533's for this reason alone.

Yes, I would definitely turn Q-Fan (variable automatic CPU fan speed
control) on.
 
Well, guess there is no real harm with enabling it.....will have to pay
attention to it for a while though....thanks to all.....John
