I need some help in connection with my new Inspiron 7520 notebook:
I have bought it a few days ago, i have installed Windows 8 Pro 64 bit and i have some strange things:
Thank you for help and advices!
Solved! Go to Solution.
I will be glad to help you. I assume that the computer is placed on a flat surface. You may then use the below link and run hardware diagnostics:
Also let me know if the computer overheats.
You may then check the warranty status of the computer using the below link:
Do send me the system service tag via private message. I will check and see what best can be done.

Thank you very much for the answer. I have called your support via phone, and your collegau told me some todos, that could be useful.
I have done it, and it seems like everything is fine and i am able to enjoy my new notebook at all!
It is good to know that the issue is fixed. If you have any issues/ questions in future do send me a message or you may start a new thread. We will be glad to help you.
birolacy, I'm facing exactly the same problem as you (although I'm using Windows 7 Pro 64 Bit). Same PCH temperatures and same problem with CPU fan running at 4600 RPM most of the time despite similar CPU temperature (also updated to latest BIOS version). Could you write steps that you followed to fix this issue?
Request you try the steps mentioned by me in my previous responses apart from BIOS update (as it is already done). If any of the steps don’t work then you may check the warranty status and follow the instructions mentioned by me in my first response.
Also let me know if the computer overheats.
After speaking Dell Support via phone i did the following steps:
1.) BIOS UPDATE
2.) Install all drivers in the righ order, you can find information if you see the link below:
Aftter doing that it seems work everything fine, altough because of I7 processor the cpu fan runs very often!
I hope that this post will be useful for people wondering why is their Dell 15R SE fan suddenly becoming loud sometimes and why this problem affects some people, while others never / rarely notices it. Especially since it's rather common.
For the past two days I did quite a lot of searching in Google and testing on my laptop to figure out, why is the fan so loud so often. It turns out that PCH temperature is a reason for it.
While fan speed is slowly increasing as the CPU temperature is growing, it's not the case with the PCH. I'm not sure why (I guess either lazy coding, or technical limitations) but something (BIOS or drivers) that is controlling fan speed is programmed to:
- force at least ~4500RPM as soon as PCH temperature goes over 67 °C
- stop forcing it when temperature goes below 65 °C
Not everyone experiences this loud fan problem, because PCH, among other things, is responsible for display (as you can see here) and thus its temperature is related to display resolution. For people with Full HD display this problem may happen from time to time, especially under heavy CPU/GPU load, on hot days or when their laptop has a lot of dust, but if someone has a display with 1366x768 resolution PCH temperature is way too low to trigger it. Unless external monitor is connected... which rises total resolution and makes PCH temperature noticeably higher. It was also the reason why it happened so often to me, as I'm often using 1680x1050 monitor in extended desktop mode and my laptop display has a Full HD resolution.
DELL can fix this problem or make is less annoying by increasing PCH temperature limit when high fan speed kicks in (if it's safe) or by making fan speed increase smoothly, as it's doing now with CPU temperature (if it's possible). Users can make it happens less often by keeping their laptop clean and using a cooling pad.
I also made a chart with some stress testing at the beginning, to illustrate this issue - you can see it here. Also with cpu usage.
birolacy, our i7 is a CPU with lowered TDP so we should expect it to generate less heat than regular mobile i7 . And it is nice and cold, only PCH temperature is a problem when using high resolutions...
Thank you for your message.
I agree with you.
From day 1 the fan has been on full blast most of the time (more then
90% of the time), even when the machine is idle. The problem appears to
be related or aggravated by having a second screen attached and enabled.
When displaying on one screen only (either the first or second) the fan
is much quieter.
Also, with two screens enabled, and the fan on full blast, the moment
you "blank" the screens (say by calling "scrnsave.scr /s" or similar),
the fan stops. When switching the screens back on (just move the mouse),
after a few moments the fan is on full blast again.
