If your room temp is around 28C then idling (0-10%) temp should be 40-50C on hard surface. Usually without a cooler load temps on my laptop go up to 95C, and thats hot. If i use a cooler it remains within 70-80C.
And in case your minimum processor usage is not 0%, you can go to power options, advance power options, processor power management, minimum processor state, and set it to 0%. Try cleaning the interior of your laptop if your willing to taking the risk.
Laptops generally run hotter than desktops, but a well designed laptop on a chill mat will seldom go over 60c core temps, and never over 80c. Newer DV-4 laptops all run extremely hot, even compared to other HPs. On one DV-4 I've seen this year, the fan didn't switch to full speed until core temps were over 80c. If you haven't already done so, reinstall windows from a clean disk to eliminate software and driver conflicts from all the factory bloat. There's a bios update that reprograms the fan controller for some dv4 models.. other than that..It's just a badly designed machine, not much you can do
Sounds like time to open it up and see how deep you can clean, air, old tooth brush and some q-tips help, with luck you can get close to the fan then clean its blades very carefully with slightly moist q-tips and then with clean dry one. Let everything sit and fully dry if any moisture was used, reassemble and air flow should be much enhanced. It's always amazing to me how the build up of dirt on the fan blades impact performance and air just doesn't get it. Good luck and cleaning will help and don't open beyond your comfort level. Coolers that don't elevate the laptop to allow air flow are a waste of time in my opinion if they elevate and had added fans mo betta !
Good Luck,

Good idea.. but don't try it without a service manual. Laptops are designed to be taken apart piece by piece in specific order.. if you try it without the manual there's a very good chance you'll break something and/or get stuck with a machine you can't put back together.
Be VERY VERY careful with BIOS updates from HP. They are irreversible if the machine cannot start to a running windows.
I have a chill mat, it's amazing and works great.
(Will multi-answer your bold part)
Yeah, I don't wanna install the BIOS update... I've heard stories about it going wrong. Thanks, though. And I have a perfectly clean install. I did that the day I got it :P
Yeah, I never take apart a machine without a service manual. I'm a service tech on the side, and learned very early on to never touch anything without a manual.
IN REGARD TO OPENING MY LAPTOP: No can do. Many people don't know this, but newer HP laptops (as far as I have been informed) have pressure sensors inside of them. It's a safety mechanism for if the laptop is dropped and breaks open... if you open it wrong, it will trip a sensor (or sensors) and all the residual electric charge in the screen will ground out into the motherboard. At least, as far as I have been informed, that is what happens. I'm not willing to take that risk. Even if it's not true, it's scared me away from opening mine. Note to self: this is why the dv4 line was discontinued... and why it was so cheap to buy...
Lol :P
I download service manuals from online. I have gigs of them :P
