Modding the Hp-dv6 laptop (Model 6199) to reduce the high temperature

post #1 of 11

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90

High temperature is the main disadvantage of some Hp laptops and despite that this particular model (6199ee) is not suffering from this problem but i tried to squeeze the best performance out of my notebook .


Specs. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02866517&tmp_task=prodinfoCategory&cc=emea_middle_east&dlc=en&lang=en&lc=en&product=5116523


In trying to do so I made the following procedures:
1- I changed the thermal paste of the CPU and GPU with better one (Antec Formula 7)
2- Removed the air filters from the intake openings to increase the cold airflow
3- Modified the direction of the cold air intake inside the heatsink of the laptop



First remove the laptop charger and the battery then remove the back cover of the lap
Remove all the screws marked with the green and white arrows taking care of the different nail sizes and their places
push the dvd-drive to the left side
remove the RAM sticks by pushing the metal sides away from the RAM stick to pop the RAMs out



unplug the HDD cable by gently pulling it up from the marked black holder




unplug the two marked cables and marked keyboard nail




unplug the white and black wireless card cables then slide the wireless card out




on the upper side of the lap gently (using your nails) try to pop up the keyboard starting from the upper left (or right) corner


Do NOT forget to unplug the KB cable (placed under the keyboard) from the motherboard



remove all the marked screws and unplug the three cables pointed in the below picture



don't forget to unscrew those three tiny screws above the dvd drive bay



starting from the upper right (or left) corner using small screw driver try to remove the upper cover of the lap




here's the motherboard finally, now unplug the marked cables from the motherboard


which are the two screen cables




the cooling fan cable


and the front speakers audio cable



remove the motherboard three tiny screws




now the motherboard is loose, on the right side of the motherboard unplug that last cable gently



remove the motherboard by sliding it out gently to the right then up out of the lap casing



the marked place is where to be modified later to allow the cooling fan to draw more cold air from under the lap



use compressed air can to blow the dust from the cooling fan



the heatsink screws must be removed in the same order of the marked numbers to avoid damaging the copper pipes




now remove the solidified thermal paste using strong orgaing solvent (I used toluene that gave me very good results)






apply the new thermal paste , Antec formula-7 thermal paste gave me much better results than the Arctic MX4



modding the direction of the cold air flow intake will need you to cut the plastic body of the lap (using your Dremel) at the marked place which is right below the cooling fan of the heatsink
I also removed the air filters from the lap openings to increase the amount of cold air intake





cut a piece of hard wire mesh to protect the cooling fan and fix it in place using strong adhesive paste (like Epoxy)




now reasemble the lap parts in reverse order to give you the final result as in the picture below



RESULTS

Before changing the thermal paste I had min temp of 38ْ C and max of 80ْ C in room temp of 24ْ C
temp was usually stable at 44ْ C



After modding the direction of the air intake, results were as follows
in ideal state after booting


after 15 min of playing Crysis 2 game i had max temp of 70ْ C (10ْ C cooler)


after stressing with AIDA64 for 5 min



compared to the following result (which was taken from Lenovo Y500 laptop) I think I made an awesome modding to my Hp thumb.gif
CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 85


The best part is that using the notebook cooler under the laptop now can make a difference in temp,
before that modding the notebook cooler has never improved the lap temp

Have fun and sorry for the long post rolleyes.gif........ biggrin.gif

since no one is posting to that thread ,so I thought i post to myself biggrin.gif

the last fan modding was not neat enough for me so I made more professional job widening the fan inlet hole at the laptop body ,and now i'm happy with the end result






The weird thing is that the temperature got even better now after widening that fan inlet hole thumb.gif

+Rep for this one!

I keep telling my friend he needs to let me do this to his machine but he's too much of a woman to let me do it. tongue.gif

Man, this is very inspiring smile.gif I'm currently battling with myself with the idea to do that on my MSI GS70 notebook. The intake holes are also not under the fan itself, and this limits the airflow. I tested running stress tests with the bottom lid off and the temperature decreases were huge.
Here's a poorly idea of the place to open new holes:


Did you notice any side-effects when you did your project? Did the fan noise increase too much? Any info that would help me take the leap?
Thanks anyways for your documenting and detailed post! thumb.gif

Ill actually be doing something similar to my own laptop at this point.

This write up was really well done though, shame it didnt get more spotlight.

Why can't you? Still in warranty? Afraid to open the case?

You welcome sir.
Sorry for the late reply, never thought the topic is still alive biggrin.gif

as for your question ,no side effects at all for more than a year now , working great ,cool and absolutely quiet .The most impressive achievment to that mod is the easy cleaning of the fans with no need to take the bottom labtop cover off thumb.gif

I think the results in your case will be much better due to the presence of 2 intake fans insted of one
