Series 7 NP700Z3AH Fan noise -abnormally loud?

[ultrah]

Also, does this white noise happen when the speakers are muted?

yes, subjectvily it is quieter. not a lot, but there is a difference.

yes, the white noise persists if the speakers are muted too.


*edit* btw, I did not replace the thermal paste yet, I am waiting for my intel 6230 card to arrive.

I can hear mine in a quiet room 5 ft away from the unit. Part of me is unsure if it's the hard drive or the fan noise.

The hard drive noise should be immediate once the computer is turned on, but the fan may take a little time to get going. Also, the hard drive noise may be amplified through slight vibration if the computer is on a firm surface. Does the noise change if you lift the computer up?

I also had this problem, noise from the fan.
I found something that really helps
switch the graphics for the web (in the SWITCHABLE GRAPHICS)
choose the power saving
I have done it in my laptop now it is less hot and the fan doesn't work so much
You should do it with every program that you don't need strong graphic

I uninstalled some bloatware and temps went down between 10 and 20 degrees. I'm thinking of doing a clean install. Now to figure out the touchpad.

Read this thread, if you haven't done so already.

I also noticed my laptop was thermal throttling when I first got it. If I ran prime 95 it was hitting 95C and then dialing down the clock speed. Since then, I followed someones dis-assembly guide and ended up replacing the thermal paste with some I own. That seems to help. I've got some screenshots I can upload if need be. The unit now idles around 40-49C and when I ran prime95 It maxed out around 78-81C which is much more comfortable and kept the clockspeed up around 2.5ghz.

by the way, whats your thermal paste made of, fairy dust and unicorns ?

I'm using arctic cooling mx-2 and prime95-64bit still gets me temps around 91C with inplace FFT and 4 workers

Do they still use thermal pad for those laptop? Because laptop components are not likely desktop, so that most of old laptops used thermal pad instead of thermal paste. I remember once time I tore apart my old HP and apply some Arctic Silver 5 and after that, CPU temp was decreased.

Not really. Video 3 in my original post shows me turning it on and putting it to sleep. There are vent holes right in the front where the hard drive is. It sounds like most of the noise is coming from the left side of the machine which is where the hd is. Left front.

Already did this.

Clean install was performed.

That was with the samsung paste...I've since replaced it with mx-4
See Video 02 For temps now. about 10-18 C cooler.

No thermal pads. 1 small fan inside the 14"

Something I forgot to ask previously: Is the HDD 5400 rpm or 7200 rpm? The latter tend to be slightly noisier. Also, how is the HDD fitted into the chassis? Is it metal to metal or are there any rubber pads?

I was referring to the temps you got with your own paste, which I assume is the mx-4 paste. I am a litte surprised because you get 78-81C with prime95 and my own readings (with mx-2) were around 91C after 10 minutes.
