SpeedFan useful on HP zv5410 (Athlon 64 3000+, 1.8GHz)?

[Lawrence G. Mayka]

My friend just bought an HP zv5410 notebook, with an Athlon 64 3000+
processor (1.8GHz). He complained that its fan was running all the time,
quite loud; so I turned on the Cool-N-Quiet feature, hoping that the
notebook would notice the cooler temperature and turn down the fan. Alas,
that doesn't seem to have happened.

Would SpeedFan help on this notebook? If so, what settings can I *safely*
apply? We are not interested in hardware mods, overclocking, etc.--just
getting stock performance with less noise.

Did you check his "power options" setting in control panel ? I have an
r3000z with a 3200 and with "portable/laptop" setting even under ac
power condition, my fans are mostly silent except when i'm hitting the
cpu at %100. Normally my cpu is at 800 MHz and jumps to 2.2G when I am
doing sims.

Turning on QnC just enables it in the cpu. You then have to set the OS to
use it. otherwise, you've done nothing.

Yes, that's what I did (through the registry modification suggested by AMD
in their Readme). AMD's own Dashboard utility clearly indicates that CnQ
has taken effect, and so the CPU should now run cooler.

The real problem is that even with a cooler CPU, the fan seems to run at
full speed all the time. I think that that is the problem SpeedFan is meant
to address.

SpeedFan is unable to access the SMB (System Maintenance Bus?) at all. The
SMB is always "busy," probably because Cool-N-Quiet seizes the bus and never
lets go.

Unfortunately, Cool-N-Quiet does not live up to its name. It does
absolutely *nothing* about excessive fan noise.

That's a MB problem, or lack of laptop type support. Not all desktop MB's
support it. Probably not most. I don't know if mine supports it or not but
I don't cqare as my cpu fan is always quiet.

What is speedfan?

Temperature fan speed control is a completely different issue than
cool-n-quiet. Some bioses support fan speed changes based on
temperature. I have three diffferent motherboards that have this
support. If your motherboard bios does not support fan speed changes
based on cpu temperature then you are out of luck. Cool-N-Quiet is
really nice when the bios has support for fan speed based on
temperature. The amd64 system I have is very quiet with cool-n-quiet
setup with the bios fan control option.

You could connect a cpu fan up that has an external fan speed control.
This was the solution I recently used for a system that has no fan
speed control option in the bios.
