Bought old colleague the elder brothers HP DV3802 notebook hp pavilion dv4 series laptop cpu fan, he has been put in the home use, DV3802 is HP famous blank screen notebook. I got the hand, also

think acura heat ah. In order to solve because temperature is too high lead to HP DV3802 blank screen, so want to work hard the transformation.
 
HP 3000 series are a special fine linear heat pipe, heat dissipation is very poor.
 
HP DV3802 radiator the above the blue is the famous HP blue small wadded jacket, thermal conductive performance special bad, through the hp pavilion dv5 series laptop cpu fan measurement, blue

cotton-padded jacket and the contact area between the video card 1 mm spacing. So I went to buy a piece of copper sheet, in the market 8 yuan to be able to

buy a piece of the (MTOOU. INFO note: on taobao $2 a), and bought a 2000 sandpaper, fine sand paper can better grinding.
 
I will display card surface is a new grinding, as if a little oxidation, the contact is not very smooth.
 
This is a motherboard chip and occurrence of chip, although calorific value is not big, but HP also use the blue small wadded jacket. Sad reminder ah, why

can't you use good point?.
 
The above is calorific larger. Although we feel is never to, but used calculation opportunity very card.
 
In fact HP notebook and a fever big thing, that is hard disk hp pavilion dv7 laptop cpu fan, hands in the bottom left corner position, temperature can be high to 55 degrees, I put the next

to the PCI slots of the plastic block slice to go to, a little better, recently do a special fan blowing it it.
 
CPU, video card, hard disk temperature and pressure test
 
I use the software open pressure test, the CPU work can to 100% I opened a night, this chart is to begin testing 5 minutes to catch, test a night CPU can the

highest to 80 degrees, video card can to 75 degrees, hard disk 56 degree. Why CPU card than high, because the temperature of the video card out of time will

pass CPU hp pavilion dv5 laptop cpu fan part.
