Thanks for the reply. I'm worry because some of the users (as seen above) said that the will spin fast and slow even he was not opening any programs. So, the volume of the fan will not be noticeable for daly use such as web surfing and word processing.

Lol no lar. Unless u set it when microsoft word is on, use the nvidia card. Then when u on Microsoft word,the fan will start spinning.

based on my personal experience, at max rpm the fan sound is as loud as most other laptop. Which is quite normal to me.
But while surfing the web(light task), after a while the fan spin at an annoying rhythm. Thats the only thing thats bothering me in the middle of the night while surfing the web. During day time or at noisy place, its less noticeeable.

Can set manually which programs to use the graphic card? I had Dell Studio last time also got this problem...fan spinning non-stop even just browsing facebook...

Did you try to contact Dell about this matter? I saw several vids on YouTube complaining this matter too. The vids are at the previous page.

ya, u can set manually which program wanna use nvidia, which program wanna use intel~

dun click games explorer then the fan won't spin so fast during fb-ing..

I though the Nvidia GPU comes with Optimus tech which can determine itself which programs will utilize more graphics power. However, it is kinda ridiculous if the fan starts to speed up by surfing the Facebook only?

Maybe facebook game make it start using the nvidia card?

spin depend cpu usage.. normal usage like play fb games or watch utube it can spin 3.2k~3.8k rpm if just on9 for surfing browser it will stay around 2++k rpm!

just received the replacement adapter for my xps 15 by now
great and fast support from Dell..very good

my laptop fan is constantly spinning all day long even when no programs are on. my temps are averaging at about 60-70c during daytime even when i'm only using iTunes and MSN.
it's kinda bugging me because my temps were between 48-55c during the first few months of getting the laptop.
but now, the average temps are constantly going up and up

Call Dell to clean it up ?

i've already disassembled and cleaned up the fan and heatsink before quite awhile ago but the temps still keep rising month after month..
EDIT: i'm thinking of re-applying the thermal paste once again even though i did so before last time. i feel like i might've not put enough thermal paste onto the CPU/GPU

ehm, don't put too much...

i only put a thin film of thermal paste last time. i'm pretty sure the temps are rising not because of the vents because i've cleaned them before...
kinda frustrated now.. the rising temps are annoying me ):

You didn't bend the heatsink, right ?

i don't think so because i remember handling all of the components of the laptop with care..
the temperature of my laptop is averaging around 68-71c now as i'm typing this message. hmm.

CPU or GPU ?
CPU usage high ?

my CPU usage is usually only 1-5% when i'm trying to get an average temp.
and using HWmonitor, my GPU temperature is always around 63-67c even though the only program i have open is msn.
