Ok i founded out why does it heat so much i opened up my Dv7 4152 with its the same motherboard as a envy the main reason its that the fan get dust to quick i clened up and about a month later was heating back up but the main thing its that once i cleaned my temp wont go over 65 degrees with turbo and overlock on the videocard now i left 2 months without cleaning was back to 90 PS(using and air gun wont work since the dust stais between the fan and the heat pipe the only way its oppening up taking the all 4 screws of the fan and cleaning thats what did it for me about the realtemp since most of us has an i7 you wont feel that much difference because what turbo does its disabling one core and puting its power into the other since most aplicattions support dual processor it should not change thats all for today hope i helped

So I checked out Steven Swanson's videos, and it looks like the alternative heat sink didn't work out. Feel free to check out his video here:
His latest recommendation is just cleaning the heat pipes, and applying Arctic Silver.
An update on my setup, even with RealTemp and Turbo Mode turned off, my laptop eventually started breaking 100C and force shutting down again within a couple weeks. Surprisingly to me, taking a can of compressed air and blowing out all visible vents really did do a great job of reducing heat, and now I'm sitting pretty at 66C after a day's use... at least for the time being.
Likely I have some fried parts in there, but the PC is usable again which is nice. I'm going to try a full disassembly to really clean the heat pipes, and remove as many plastic parts as possible. Also, I did the 'write the CEO' thing on the HP sites just to voice my disappointment, and as expected they replied w/ some basic customer support that I'm humoring for now. Will let you know if anything comes of it, but as I'm outside of warranty I have zero expectations.
Good luck as always.

I did that "letter to the CEO" thing. They eventually phone you back (or you phone them on an 0845-UK chargeable number), get a case ticket number, and then they tell you, after investigation of what they can do, that you have to send your E17 away at your cost (Fedex collect), analyse it (presumably by cooking food on it), repair it (where there doesn't seem to be a viable repair) and charge you for that too. Takes 2-3 weeks. Meantime I also got a personal message from HP US "Exec" support, offering to find somebody in EU to help. That went nowhere. I assume that person was silenced or made redundant.
I am still thinking of writing to UK Trading Standards around the fact that the E17, as sold, was and remains unfit for purpose. It isn't a computer, it's a rather dangerous cooker.
I wish a journalist would pick up the cause!

I had the same issue with my HP envy 17 1090. after 4 months i had my first critical shutdown send it in for repair got it back and i worked for like 3 months again and then the same thing happen 80 degrees celcius when it was idle, and the fans blowing at full speed. I didnt use it for nearly a year. Then i tried to disassemble it and change the cooling paste to arctic silver, now it runs like a charm. 45 - 50 degrees celcius in idle and around 70 degrees playing diablo 3 for hours and it will maybe have some peaks saying that it went to 85 on my HW monitor but usually it is right around 70 degrees and running perfectly stable with next to no noise from the fans.
The cooling paste HP had applied was a mess! and it was like clay...
I have some pictures here on my blog how it looked like no wonder it gets so hot...

Hello my name is edward. recently i bought a hp envy 14 and guess what it freeezes too. the temp its around 80-90 just by replying on this forum. so what i did is opened the laptop and took a look, yeah for an i7 the cooling design and the fans are a joke. also here is the funny thing. one of the fans are located in the back so the airvent are there. i included a pic. so when you open the laptop screen the screen it self blocks 3/4 of the air vent cousing it to be even more hot.
as a business men i dont use the comp for games or have programslike photoshop..... it legs just by going to firefox and typeing in the broweser. called HP and they told me clean out vent, check bios update, windows update, reformat to outofbox...... i even changed the thermal paste. so save your selfs time and dont do all of that because it will not help (maybe 3% diffrence). also sent the laptop 6 times to them already since they dont want to change it even if still under worrenty. so i guess ill keep sending it to them every time i get it back because i dont want this laptop. here is my suggetion if we can get enoughf people to agree that this product is defect. i can hire a lawer to sue.

ok guys so i did a video to show you why does it heat up you can see the result at the end its lower 20 to 30 degrees just by cleaning up i do it monthly
If you not sure what you doing dont do it, take to an IT shop.
sorry for my english
BTW it wasnt that bad this time but it begun to heat up alredy first time i opened up it was way worse and as you can see it wont work if you use a pressure gun because it just sticks there
video link any questions you can email me firstname.lastname@example.org

Hey Edward, I'm very sorry that you are in the same overheating mess as the rest of us, I think you're just out of luck here. Similar to yourself, I primarily use my laptop for business, so having overheating during those sorts of simple use is extremely frustrating. HP write the CEO was pointless, they offered to pay 50% of repair costs and completely ignored my comments regarding their recognition of a structural fault.
I just wrote this response and lost it... my fault for leaving tabs open for days. Will do a brief report here, but taking apart, fanning down everything, and applying new thermal paste did a great job for me. I also found a piece of black plastic covering the vent in the back you referred to, and I took that out even though no air is directly venting there. I also removed a piece of black plastic reinforcing the main left vent, just figured the less plastic in there the better. Tradition2's post is really good, and when I inevitably have to take this thing apart and clean again, I will definitely take apart the fan and clean those connectors.
All in all, I'm still using RealTemp to disable my i7 Turbo mode, in addition to a Zalman cooler, but the PC now sits at 55C after a day of business use (web browsing, MS Office, file transfers, video), and is <50C idle. I think if you brought a lawyer into this you would have a decent case, but frankly I don't have the time or desire to fight this anymore. As everybody on here has mentioned, HP should be ashamed of their behavior here, and I plan on never purchasing / recommending purchase of another HP product again.
Thanks everybody for your help here, and good luck.
