dv2815nr is one "hot" pc.

Excuse the pun..

I have an HP dv2815nr laptop, not the best not the worst, I just use it for what ever.

Well the other day I decided I have had enough of this heat and decided to see what's up. I know things get hot 'n toasty. I didn't expect to find anything odd but I downloaded CoreTemp from alcpu.com/CoreTemp and HD Tune from hdtune.com and see things. Well this is what I found.


Let's start with mah harddrive.

Samsung HM260JI is apparently rated to: 55°C/131°F
HD tune says that it's getting to a nice 'n warm 62°C/143.6°F

This concerns the Derkek. Right now, I'll admit, I am running the HD tune hard drive utility and and light browsing the web, but this shouldn't make it get above the rated temperature, right?

As for the CPU. AMD turion 64 x2 TL-60
rated at 95°C/203°F Lucky Derkek's cpu isn't getting above that temperature.
at temp#01 being 91°C/195.8 and temp#02 87°C/188.6°F

cpu is good. But what about my hard drive, it's pretty high up there on the warm scale. Whaddaya think?
I also tore apart my computer completely and cleaned it. I don't have a bottle of compressed air with me so I brushed it with a..well a brush. Tomorrow I might do a more thorough cleaning. But what can I do to bring the temperature down?

 

Nothing really. HDD temps are going to stay like that. I tried wrapping the HDD in aluminum foil, making a foil barrier from the laptop...put it on a podium...the HDD is going to keep toasting until it dies. Just how HP designed the DV2000 series along with the current DV4...

You may want to try to get some arctic silver thermal paste and reapply it...might be worth a shot. And try to use a vacuum with the brush wand when you clean it again.

I mean, your pretty much SOL, but...these are worth a go. You're lucky your system is still chugging. I've had two DV2000 systems die on me from heat not to mention all the hard drives that died...

 

Undervolt your CPU, it's the reason your computer runs at high temps in the first place.

 

i had to change the hard drive on my DV2000 cause it overheated and never worked the same after that. i was lucky to find a brand new one for 30shipped

but yeah still gets really how, so just make sure the vents on the hard drive are not blocked(i had the laptop on my lap so was blocked lol)

 

I've had quite a few hard drives fail in my dv9000 until I went and got a cooling pad. The Zalman NC-2000 might be overkill for your lappy, but I'm sure it added at least a year to the lives of my hard drives. It brought their max operating temp down from 57 to 45. That's a huge difference.
I didn't take the cooling pad with me, but since I mostly used the computer at home, that's where it needed the most cooling. i still have the cooling pad for my dv8 (it barely fits!), but it doesn't seem to need it as much.

 

I'm surprised that you had heat issues with the 9000. It's a large machine and it cools itself quite well. But as for the OP, the answer is here.

 

That's what I thought. It was not the case. I measured temps last week, and while sitting on a cooling pad, just displaying the desktop, the GPU got up to 73 degrees celsius, and the CPU up to 60. Although, even with the GPU running as high as 94, it still ran. Eventually it failed, tho, and is now on its 4th motherboard. Sometimes, extended warranties are a good thing.

 

It's not the heat itself, but the constant pumping of temperature up and down that causes the nvidia chips to fail prematurely.

So having the laptop hot all the time isn't as bad as high-low-high constant changes. Best of course would be keeping it cool

 

I'm still on the first board FYI. Had a few quirks every now and then but she still runs like a champ.

Depends how cool. They do not like being powered up from a cold place (sub 20C). I've explained it a number of times but i'll do it again. When the chip is powered up, due to the amazing quality of the thermal pad that HP provided, the temperature shoots up from whatever it was to 60ish degrees C. All chips start without any type of power management so this is unavoidable.

This wouldn't be a problem in itself, and does not damage the chip. What breaks is the god-awful RoHS solder. Environment friendly my a**, it produces 30% more failed devices and few people really recycle them.

The somewhat permanent fix is to install a copper shim between the GPU and heatsink, with thermal compound on both sides. This will make for much better thermal transfer and less chance of the thing failing.

FYI my 8400GS runs at 60ish idle with powermizer off (powermizer messes up my sound), and i've only seen it hit 82C even when gaming. And i overclock the crap out of it. I haven't modded my own board yet with a copper shim, but i did take it apart when i got it (if you read the link in my signature you'll see the story), and put new thermal paste everywhere including on that crappy pad.

 

Great. One missclick and a whole wall of text disappears. >.<

My 8510w runs 30-35C CPU and 45-47C GPU idle at the moment. That I think is cool enough

In the last 3-4 hours I pulled apart one dv9000 and baked its motherboard in the oven. Assembled it together and at least it boots now. Next task is OS install.

There was surprisingly little amount of dust inside but computer had run really hot at some point: exhaust vent grid at the back is warped by the heat. At least I think so, I dont have another dv9000 to compare with.

I added copper plate over the nvidia chipset but that was too thick to be used on the GPU, heatsink didn't touch the memory chips anymore. I did add thermal paste on GPU and CPU, neither of those had it before. If I get this machine to work, I wonder what temps I'll see.

Edit:

Couple hours later XP installed and this seems to run 47C GPU and 40C CPU on idle, battery power. 50C GPU, 44C CPU on AC power. Have to run some stress tests later.

 

If it was too thick then you should have used sandpaper. Anyway temps look good, looks like that thermal paste did the trick.
