So much technology for nothing
Posted: Mon Mar 02, 2009 7:41 am
Hi all,
This may be my first post here but I've been following these forums for a really long time now.
All I can say is that we claim to be so technologically developed, but we still cannot have a cool and silent laptop, no matter what! And even in my workstation I had to devise a huge system just to cool it down without any noise pollution.
The laptop I have (HP dv6780ep) has the folowing pattern: 33º C on the cpu activates the fan. The temp. goes down to 27º C and the fan shuts down. These temps are given by RMclock, but speedfan reports generally 3º C more (speedfan doesn't really work, I just use it to monitor the temps) and these are with the system running at 600MHz.
The GPU is stationary at 60º C because I don't need all the power in the geforce 8400m gs.
I will shortly patch the dsdt table to make the fan run at 20% all the time instead of running in short 15s bursts every 90s.
With the zalman notebook cooler (only one fan at half speed) the interval between fan activation is 150s or more under normal internet/office use. With the zalman cooler running both fans at full speed, the laptop's internal fan only activates under long heavy load, the problem is that the noise coming from the cooler is almost the same as the one from the laptop, even if it's less annoying.
I'm looking for advice on how to undervolt the geforce (i've tried rivatuner and another stuff but it didn't work).
Also, I was hoping that I could change the heatsink+fan assembly, or at least mod it. Anybody knows about a compatible low noise blower fan that I could use. HP heatsink fan part 450933-001.

Any other suggestion?
The reason why this is so important (besides hating the noise) is that I'd like to use the laptop for mobile sound recording and maybe in the control room, but then I couldn't have it running at 600MHz!! I thought about buying another laptop but I figured I would never get the perfect one, so I'll just save the money for something else that makes me happier.
