Heatsink for DV9000?

i just took apart my laptop yesterday to change my cpu on it. i was running T7500 and changed it to T8300 and man.... that T8300 is sooooooo cool. with AS5 my idle temps are down to 25-27*C thats a HUGE jump from my old T7500 which was a mini baking oven.

but anyways.... it took me 3 hours to take everything apart watching videos videos on hp.com but onc ei took it apart, i looked at the HSF and man its one of the weakest hsf i've seen. the only part thats copper is just a tiny square base thats on top of cpu. everything else is crap. and there were some pads on the end of the hsf to i guess cool the little things on the side. (forgot what they were called) i wanted to apply the AS5 to all the places that the pads were touching, but that part of the HFS was not copper. i'm not sure what it was.

i'm sure everyone that ever replaced cpu on the DV9000 had taken the whole laptop apart... have you guys ever thought about replacing the HSF with an aftermarket HSF thats better than the stock? i tried searching and found none that were any better than the stock. none of them are all copper.

and i did not want to put AS5 on the other things that has that white/beige pad on, since the bottom of the HSF looked weak and i did not want to fry the chips/what ever the pads were supposed to cool... can you guys help me find a better HSF for the laptop? or that stock crappy hsf is the best/only thing for me?

 

come on guys, no one has bothered to find a solution for crappy stock heatsinks on the Dv9000's?

 

I wish I had a copper heatsink.

I would like to see this thread come alive.

 

If you think the DV9000's heatsink is weak, you should see the DV5 series. When i got my DV9000 (i bought it with a fan fault, see sig), that heatsink alone was enough to keep it running for 25 minutes. I don't think that can be called weak.

PS: Those idle temps look way too low. Is it winter where you're living?

 

no i'm in san diego, CA. but for some reason the temps are now idle at 31-33 *C hum... did i screw up installing the AS5 or something? cause its weird if the temps were in the high 20's just after installing the T8300 and AS5. but now the temps are in the 31-33*C idle.... did i screw up somewhere? or is this supposed to be normal? that is about 5-7*C jump in idle temps... hum... i wonder what happned. i mean if i put my hand under the fans... i can feel the small cold breez coming out of it. well its not cold, but its not even warm either. i guess its in the middle:confused2:

what are the average idle temps should be on this laptops anyways? i never got around to check what my old T7500 temps were. i thought bout that as soon as i finished putting back together the whole notebook. and i was not going to take another 3 hours to take it apart and put it back together for another 3 hours... the only thing thats actually hot/warm is my primary HDD. that one is warm/hot to touch. geee i wonder why lol. but i had just bought a used OCZ core series V2 30GB form another forum for just $40 shipped so i'm thinking about replacing the primary with that one. so no more heat from the HDD, and i guess that might drop my idle temps back to the high 20's maybe?

i was reading that you have to choose that IDE thing in the bios before installing windows 7 on the SSD, how the heck are you suppose to do that? i went into the bios 3X's and i did not find no options on IDE anywhere. for those of you that have SSD's and win 7 on them, how did u do it?

 

The temps are very good. My AMD based DV9000 idles at 40C and that's perfectly fine. I'm gonna say it again, idle temps do not matter. Load temps do.

I don't think you will have to change any setting to install Windows 7. Maybe if you wanted to install XP... Anyway, you won't find that setting in the BIOS.

 

You might have an older version dv9000's heatsink or something.

All the pavilion ive worked on, use copper piping and heatsink which looks like this:



The heatsink fins will look black but it is still copper just sprayed black. Black is the best color for dissipating heat. (same reason the piping in the back of refrigerators are black)

 

The fins on the heatsink look more like aluminum to me. However you are right about the heatpipe, it is copper on all Pavilions, at least all that i've popped open.

 

my heatsink looks just like this,

except for different color thermal pad. the only copper it has is that little square of copper in the middle where it sits on the cpu. i was looking at some heatsinks on ebay and i did not find any that looked like this and were all copper like the ones in your link. ( http://www.myeasypics.com/is.php?i=591025&img=DSC00897.JPG) i wanted to take those silly thermal pads off and put AS5 on it while i had the whole laptop apart, but then tere was no copper so i got scared and kept the pads on

i don't know why mine is soo much different than yours, but i guess its probably because of the age? but its not been too long since i got the laptop. maybe 1 1/2 years max? but the laptop don't feel slow at all. i replaced the T7500 with T8300 and now i got the 30GB core V2 ssd and man this thing fly's. windows 7 boots in 30 secs flat shuts down under 10 secs. better/faster than the new laptops that cost like 1300 bucks at costco and only have that puny little T6500 cpu in it. the only fault i can find on the laptop is the gpu which i can't upgrade from the old 8600GS M i wished i could change that as well. or buy a motherboard that i can replace the gpu on.

but back to heatsink, ya so from the sound of it, my laptop is supposably tooo old, and there is no way i can put the heatsik that you guys have in my laptop then


and what programs do you use to stress test your cup and log the temperature. the TJ Max on the CoreTemp was at 105*C maybe thats why its showing my idle temps so low. isn't TJMax supposed to be like 95*C or something like that?

 

Your heatsink and pipe is all copper, its just being held by an alloy frame.

The red thermal pads on that photo are for the northbridge chipset, do not touch these.

The blue pad is for the GPU, you can replace that thermal pad with a copper sheet of metal aka the copper modIve done it to my dv2500 and instantly lost about 20c on GPU temps. The thermal pad HP uses barely conducts any heat!

All in all, there are no internal aftermarket HSF, for most or maybe even all notebooks. What you will need to work with what you have.

If your heatpipes are black and dirty, try cleaning it off it helps.

Trust me they are copper, if you look closer or ever scratch it you will see the copper.

Heres a dv2000 heatsink i had lying around:




You can see the copper fin on the side and its noticable that it was sprayed black

 

WOW that is a GREAT mod there bro.man... i wished i saw this before i took my notebook apart. now i don't feel like taking it apart cause it takes so frecking long.... but i bet its worth it. dose the thermal paste really have to be spread out on both the gpu and the heatsink? i can't just put a small dab on it and do it... cause i don't want to put tooo much on it and ruin the whole thing by making it too thich. like you said if i can't find any aftermarket heatsinks... this is my best solution. i will definitely give this a try as soon as i get me some copper and some IC diamond 7 tim i've tried AS5, now its time to IC diamond 7 and see how it goes. i wana wait about a week, i want to give the AS5 time to settle in and then do some stress tests and see how that goes and compare it with the new thermal paste.

for those of you that have DV9000 and did cpu load tests, what was the max load temps you got? since this laptop is not overclocked or anything, i was thinking maybe just let the cores run 100% for 30-45 minutes in Prime 95 and get the temp from that? since i'm not testing for OC stability or anything.
