DV 6000Z noise and heat

I am testing my Dv 6000z these days and found a pretty interesting finding. I wonder if it was just me, maybe you guys already know this.
When on AC power with Max performance idle temp is 50c and highest 67c, and fan will kick in around 55c. However the fan wasn't not loud tho, but for sure it came up more often than old my DV5000z.

Next thing, I tried the battery power. Idle temp still 50, but it will never go over 56 and fan will never kick in. I put it at dynamic power still no chances.

Third I plug the AC back and set the power to portable laptop also in dynamic power. It went back normal just like with Max power!

I wonder any of you that own this baby got some similar result or different? or maybe some opinions

 

HP laptops typically set the maximum CPU speed lower when on battery, which would explain your observations. Lowering max speed slightly also lowers max core voltage, which makes a BIG difference in power consumption.

 

Brainstretch,

Can these settings be modified in Windows so the fan doesn't always kick in with the a/c plugged in ?

 

Nope. If the fan kicks in it's because you need it.

 

hey guys...I am thinking of buying this laptop dv6000z...Do you guys recommend it? Also is it a quiet laptop?? I mean can you hear the fan all the time or does it kick in from time to time?

thanks

 

I'm a dv6000z owner myself and dualbooting with XP and Vista. My BIOS version is f19. Since you're just buying it, then yours is probably even newer(i bought mine in November 2006 and haven't updated it yet).

The fan kicks in depending what you're doing with it really. If the CPU usage is around 30%, then that makes the fan come on after every few minutes for about 20 seconds or so. The higher it is, the more often it kicks in and stays on.
If you're just browsing the web, then it rarely kicks in. Some flash sites may, however, use a lot of CPU power, thus causing the fan to kick in also.

Vista causes the fan to come on a little bit more often than XP, as it's doing more background work. But my Vista is tweaked down enough for the difference to be that noticeable.
Reading about the fan problems some people are having, then i am pretty happy with my dv6000z.
Getting a notebook cooler pad would be a good idea though.

 

If you use RMClock, you have the chance to control the on demand clock. Just set the maximum on demand clock lower than the max CPU clock, you will have less heat generated. However, you will sacrifice the performance. The higher the clock, the more heat dissipated. You can even put your AC profile as the same of battery profile. But, hey, what's the different you want?
