Hp Pavilion dv7 heat issue, need help

Hi all,
some of You already know what it´s about but ill sum it up with pics here. So the problem is, i upgraded to my processor to P9500 and since than my temps have gone straight up for 10-15°C. Meaning both cpu, gpu and one of the hdd´s which is near the gpu and it´s memory.
Laptop Specs are in the signature and here are the idle temps now. (HDD goes up to 59°C on idle)


Here is how i proceeded with the upgrade. Thermal paste used was Arctic Silver 5

The disassembly was harmless and it takes me about 10mins to do it completely. This is my MBO as it looked like with factory paste etc.

So after switching processors i cleaned the old paste nicely

Also the heatsink was cleaned

First i used the line method (maybe too much paste here), than, later on i used the line method with less paste, than the "dot" method and at last the "spread" method (more paste-less paste-almost no paste etc.). All of them brought me the same high temps.

This one is just to show how the paste spreaded....


I tried removing the black thingy that was on the heatsink, no change.
Now i am wondering if these thermal pads could be the cause, they are a lil´ dirty now.


Right now i´m about to disassemble it again trying i dont realy know what. Any new idea would realy help me out here.... THANKS!

EDIT: I tried updating Bios-no change, updating Catalyst drivers-no change. With the old T6600 cpu factory default temps were cpu=35-40°C gpu=47-48°C hdd´s= 35-40°C

 

Nice pictures!
I'm sure lots of people will appreciate.

Weird! The P9500, with is lower TDP, shouldn't heat up that much.
How high the temps are raising while gaming?

The thermal pads you're pointing at are crappy for sure, but I don't think it explains the why it's so hot in there. Most are for the GFX RAM, one for Nothbridge it seems. I'd try to look for GAP between chips and Heatsink's copper plates. Gap that could be filled with "copper mod" maybe?

The HDD at 59 degrees idle is running hot! Lowering it's life expectancy IMHO.

Did you try a full Windows re-install? Might be some ACPI functions that are screwed up, just a shot in the dark.

 

59C for a hard drive? jesus christ, can you return the unit or is it too late?

i would not trust that drive after being exposed to temps that high. my hdd has never gone over 40C in my dv7t - and i'm running 2 drives - 5400rpm tho.

 

When i take the HDD outside, but still leave it connected and the laptop running it cooles down to 30°C and below, so i would think it has something to do with it´s proximity to the gpu and it´s memory. I surely can try win re-install if you think that would help. I´ll do it later today and report back.
If required i will post all pic´s concerning disassembly if there are some pavilion dv7 users wanting to upgrade

 

I run it now with bios setting "fan always on" till i figure something out. With that thing enabled all the temps are mid 30°C and below.

 

u should always keep the fan on in BIOS and this might be the cause of the problem...

 

^ agreed. my fan is always blowing hot air out of the back of my laptop. only when gaming, the fan speed gets way higher to get rid of the excess heat.

factory defaults in the bios is that the fan is always on, correct? that's the way it should be, IMO.

 

if you temps are now OK with FAN ALWAYS ON, I'd say everything is fine now, no need to re-install the OS.

Every decent piece of hardware nowadays uses a fan to exhaust heat and should always be kept ON to increase hardware components LIFE Expectancy.
Sound (the fan) was maybe your concern, but keeping the lappy cool is paramount!!!!

Your HDD will be ok IMHO, if it now runs cooler. Hopefully it didn't run hot for too long.

 

The fan function in bios was turned off... factory default temps were as written above (with the "fan always on" function disabled). It turned on when needed, now i left it always on ´couse of the temp problems. My HDD, the one i have problems with does not get hot while outside of the notebook case so i am guessing again that it´s proximity to the gpu is making it overheat. While the solution is to let the "fan always on" function be, there still is a problem. Notebook should not overheat on itself while running idle, even with the "fan always on" function off. I want to fix that.... I do have some ideas left (new thermal pads, copper mod). I´ll report the results back, also with pics

 

This is more than a year old topic but i do still have the same problem (was out of country)... idle temps averaging about 50C cpu, 55C gpu and 45C hdd.. meanwhile i tried another thermal paste (arctic cooler mx-3) but no change. So today i ordered some new thermal pads a 3xcopper mod for gpu, cpu, and that video chipset thingy that has a thermal pad over it atm... no idea what else to do . Btw. i take that laptop apart and togeather again in like 10mins, had so much practice with it .
Any new suggestion is welcome.

 

If it is cleaned
The idle temps for CPU and GPU are not anormal for a summer day. If the ambient temperature in your house is around 25-30C it can be justified. The HDD temp seems too high but you have 2 which builds more heat.
Maybe you can try to replace one by an SSD.

 

ur CPU temps are perfect.. GPU is ok but if u use 186.81 driver or 195.62 drivers , the idle temps should be lower. Your hard drive temps are too high due to hp hard drive module doesn't have enough ventilation.. u could drill holes in the driver cover case under the laptop to improve ventillation.

 

Both good points, i understand that the temps are not that dangerously high. The thing is that the stock temps with the T6600 were much lower before i tampered with it. I mean like more than 10°C lower...
I will try that copper mod and replacing thermal pads and if that does´nt lower it i´ll just let it be.
I think i could make some pics of dv7´s disassembly process so at least i would be contributing something to the community
