DV6563CL w/ Win7 64 bit - Fan LOUD at start up or after sleep? Maybe Nvidia driver related?

Laptop: DV6563cl (Intel Core 2 Duo T7300, 3GB RAM, 500GB/7200, 15.4 inch, Win 7 RC 64bit, 128MB 8400m GS)

Hi,

I recently bought a 500GB/7200 RPM hard drive to my laptop and I decided to install Windows RC 64 bit. Before doing the hard drive update, I had installed the 7 RC 32 bit since it came out.

Now, I can't recall when I had the 7 RC 32bit that the laptop's fan was running on full blast after sleep/stand-by. It is also loud when you start-up the computer from a restart or after a shut-down. The fan speeds down to a quiet speed/rpm after...I'd say 2-3 minutes.

I installed everything listed on HP's website for my laptop (drivers and such after installing 7 RC 64bit):

I noticed that the Nvidia driver on HP's website was not a recent one, so I hopped on Nvidia's website to get a newer driver instead (186.03 I believe).

I have my laptop set to Power saving's mode and I only bump it to Balanced when I'm doing something heavy (like iTunes encoding, etc).

I did check to see if maybe my anti-virus program that's installed (avast...AVG didn't install when I went to 64) was doing scans or such, but it isn't. Well, actually I take that back...does avast do a very slow/quiet scan in the background? I see the HDD status light blinks steady, but when I pause avast, there is not steady blinking.

I'm fairly good at not letting anything run in the background (like the useless quicktime icon, etc near the clock)...but I can't determined what's causing the fan issues?

Btw - I am planning to replace my fan inside my laptop because it's starting to make an annoying noise (at low rpm) and I've already opened it to clean it before.

Any help would be great!

 

It's normal. My DV9700 does it too when i boot, but only for a few seconds. I believe it's doing some sort of internal check.

On the other hand, if it sounds weird at low rpm, maybe it's time for a replacement.

 

Mine usually does that when it's turned on too, but it stays at high rpm for 2-3 minutes, while operating in Windows (not just within the BIOS boot).

 

Replaced the fan last night, now it's quieter when it's at low rpm.

BUT, it does not fix the issue where my laptop is loud for the first 2-3 minutes after Windows 7 loads up to the desktop. Any help still?

 

No idea really... My dv9700 has something similar, if i carry it around holding it by the keyboard side (so the main body of the laptop goes vertical and the screen goes horizontal), the fan will suddenly start screaming, and the notebook will shut down sometimes. I checked the temps and it thinks that the GPU suddenly goes to 125C when i carry the laptop like that, but that's impossible since the cooling system is properly fitted, and in a normal working position the GPU doesn't get over 80C. I now always close the lid when i carry the laptop around the house, with a 17" screen i could easily bump it into something and break it so it's better like this anyway.

I think yours has something related (bad temperature sensor). Unfortunately i don't think it can be fixed.
