dv5z - AMD turion ultra on fire

i just bought my dv5z with AMD turion ultra ZM-82. previously i had the dv6-6750en with turion 64 x2 @ 2.4 Ghz
the issue is, when i switch on my notebook, the temperature STARTS from 65c+, a bit of net browsing, it remains in 60'sc, use any software or media or something, touches 70C, multiple softwares or a bit intensive app, it even reaches 80c, no question about gaming yet, i play a game for 2 min, and the CPU temperature is near 75C
this is the whole scenario. all these temperatures are recorded in an airconditioned room, with the lower part of the notebook raised by 3-4 inches to allow the fan to work properly. that was the most i could do. is this normal?
what solutions could i go for? any fan speed control or something? please help me out. you guys are my only hope

unlike you guys, i can't return the notebook and go for dv5t. though i seriously love this one. the previous amd turion 64 x2 never gave a heating problem no matter how much stress i used to put on it.

 

btw, as the temp. reaches 70-80c, i shift to 'power saver' power plan, that quickly reduces the temp. to 60c, or even 55c
the thing is, while i've read the posts here for dv5 n dv7, every1's facing a temp. in the range of 40's while my notebook STARTS from 65.

 

Have you tried undervolting with RMClock?

 

undervolting? well, wouldn't that reduce the performance too? and that's not something i paid $1200 for like every1 else here having their thermal zone and CPU temperatures in 30'sc, i would like mine too.
but like i stated, in the power saver power plan, the temp. reduces to 50's

 

Undervolting does not decrease performance. It simply lowers voltage usage (thus less heat) to a more acceptable level since the CPU does not require that much voltage. If the voltage is too low, performance does not decrease, rather the laptop either BSOD's/freezes because it doesn't have enough power, so you just have to set it to the right voltage so it doesn't do that.

More information in the undervolting guide.

 

Hi.

I would return it and get a replacement! , I should be getting a ZM-80 based system this week and if the temps are anything like yours i will be after a refund!

EDIT : Have a look at this!

i read the undervolting guide. right now performing the orthos cpu stress test, the maximum it reached is 88c, just 10c more than that flipfire guy who wrote the guide. but the thing is, it never goes down from 60'sc when idle. while i've seen the dv5z review here, the temperature shown were in the 40'sc range. why is that?

oki as i live in pakistan, i don't have such options of refund etc.

 

can't undervolt...
rmclock doesn't read amd's new turion x2 ultra
now what should i do? these temperatures are not at all reasonable.
also, i can't get to display the temperature of my graphics card - ati radeon HD3450
tried several apps but to no avail.

 

Some people have reported success with cleaning the heatpipes:
http://forum.notebookreview.com/showthread.php?t=285546

 

i bought the notebook 7 days ago. why should i consider the cleaning whatever there is, cleaning the heatpipes would make a difference of 5c at the most. right now we're dealing with 20c higher temp.'s

 

As long as you're not hitting 100*C+ temps, you should be fine.

 

What happened to cool n quiet, It`s as loud as hell and red hot!!!!

 

i'd ask the same question again, in the dv5z review here, temperatures were in the 40'sc range, then why mine are 20c higher though i've the same notebook.

 

20c difference is a lot.

Is there a way to look at the fanspeed? Maybe fan is having problems or the heatsink had fallen off or misaligned

I'm wondering this warrants a call to HP tech support

 

have you updated the bios? If you have vista, have you tried putting the notebook in power saver mode?

 

mine idles in the 60s too. Seems to be pretty typical really.

 

OP I have the exact same problems as you do. My CPU hit 88 degrees celsius in the test.


Really sucks because I like this laptop, just the heat is an issue.

 

exactly. just heat is an issue. well, i updated the bios to the latest F.08
oh and the power saver mode helps me to remain in 50'sc but then, it shouldn't be like this. i'll have to wait to undervolt it till this NHC software gets an update for new AMD processors and better vista support. (RMclock doesn't support new AMD processors)
btw, can i claim warranty on this issue?

 

as 'uncming' talked about fan speed, is there any software to control the fan speed? as in if i can increase the fan speed and see the result?

 

There's no fan speed controllers for HP notebooks.

 

I wonder if your heat sink is not seated properly. I would try taking her apart and re-seating the CPU and heat sink. With some arctic silver or something.

 

IIRC, someone mentioned a BIOS option to run the fan 24x7? Make sure that's enabled. It may be irrelevant given your temps, but...

We're also assuming that your temp monitoring program is reading the CPU's thermistor correctly. It probably is, if the fan exhaust is hot. If it's not hot but you still think the program's results are accurate, mgh_a1's suggestion is worth thinking about. Hot exhaust says that the heatsink is doing its job.

I can only speculate as to why some notebooks run much hotter than others.

 

is room temp a factor?

 

well I assume it would be, since in a hot room the heatsink is only getting warm air to cool the CPU/GPU.

 

So its either on or off? There should be a way to throttle right?

Anyway - as I mentioned it really sounds like something hardware related either:

1) Fan/heat sink is misaligned

2) Fan is not spinning fast enough to move the heat

3) Clean out the heatpipes

Either way, have to crack it open. Either you or HP

 

room temperature is not a factor. i always use my notebook in an airconditioned room. what i've decided is to go to the local store here, from where i purchased it as they're responsible for my warranty. let's see what they come up with. i'm pretty sure they'd never give me the 21 days replacement warranty option.

btw, i just noticed, my notebook's on idle right now, temperature is 65c avg. but the fan is apparently off. :S is there any software to keep a check on it, if it's spinning or at what speed? and yes, the 'always fan on' option is enabled in BIOS.

 

dayyum, i restarted my notebook once, and the booting took the CPU temperature to 80c, and the fan just doesn't seem to work. may be this is what the issue is all about.

 

My temps were as high as you guys when I first got my DV5Z, this is the solution:
1. Keep the room cool, it makes a HUGE difference (and when I say cool, I mean a comfy level, dont let it get boiling hot in the room)
2. If you have the F.11 BIOS (not available on the HP support site yet, but it is on the newer DV5Z from the factory) keep the fan option set to 'ALWAYS ON'
3. In Vista go to the advanced power settings and change the MINIMUM processor state for the High Performance profile to 5%. (This will not reduce your perforance in any way, it will only let your processor idle at lower speeds and temps when it is doing nothing!)
4. Verify results with HW monitor and AMD Power Monitor (your processor should idle at 500 Mhz when you aint running nuthin but WIndows and Live Messenger)
5. Invest in a good Cooler (NC2000 on its way!), even if you dont buy one the above steps will ensure you never cross the 65C mark (which is all good) without losing any performance

My temps stay around the 40C mark at idle after dong the above and have never crossed the 63C mark at full load since the above fixes!

If these fixes help, hit the REP button!
and pls contact HP at :

and request a new BIOS enabling HYBRID CROSSFIRE for the DV5Z be released!

 

^ ur steps sound quite genuine. good one. but i just returned home after giving my dv5z BACK
the temperature issue was getting serious. now i've 2 options:
order another dv5z-1050ee OR, dv5t-1060ee with the following specs:
Intel core2duo P8400 @ 2.2 Ghz/3MB L2
3GB RAM
250GB HDD
superdrive with lightscribe
Nvidia 9600M GT
and blah blah..
i'd like you guys opinion. it's almost of the same price, hardly $15+
what should i go for? the dv5z has more HDD, fingerprint, and blu ray. (not to forget, a sexy AMD turion ultra sticker )
please help me out in deciding on the purchase. i've 1 more day to decide.

I've really found that the temperatures just varry based on what your doing. I've sat there and mapped stuff out. I have a dv5z with the 2gb turion (not the ultra) originaly with 2gb of ram (but i just upgraded to 4gb gskill) and the 4350 video card. Bios is F11 from the factory. Anyways, under idle without any programs running in the background, and without being in an air conditioned room i can get the thing to sit as low as 45C but typicaly 53C. Anyways when i run outlook, aim, and mirc. the system sits at about 60-65C. Now here is the kicker. If i start doing a network transfer of large files across my LAN, my temp jumps up to 75, but drops back down as soon as its done. And this is the even weirder part, if i run azerues, even for just a few minutes, all of a sudden the temps are spiking into the 80s. Now, yesterday i upgraded to the 4gb g-skill ram. Since then, it's been running cooler. with all those programs, including azereus, it's idling at about 74. Now, after a bit of experimenting, i've found that proping up the back by just a little bit (or hanging it over the edge) allows for more airflow and the temp does drop a good amount, so it really just matters on how much load you have and stuff. Even though i have 4gb of ram, i swear it runs cooler than the factory 2gb. For testing i have been running SpeedFan 4.36 to watch the histographs of all the temperature spikes. There is something i haven't tried but i've been thinking about. Putting a 4gb SDHC card into the card reader slot to give 8GB of ReadyBoost to the system. I've been reading over the specks and it can really take a good amount of strain off of the hard drive and keep that a bit cooler. Anyways as far as i can tell, the way to keep things cool is to decrease the load on the cpu and the graphics unit. If you step down the capabilities on the graphics processor, it should keep things colder. When i'm running on battery, the system doesn't get much hotter than 53C.

 

Thanks Ali,

Go get that SEXY DV5Z with blu-ray back, you will be glad!

 

It sure sounds like your notebook simply had a defective fan. I'm surprised it didn't get hot enough to force shutdown. Try another one at the dealer?

 

Yea, thats probably it!
My DV5Z is cooler than the other side of the pillow!

 

@SMAN
previously i had a 6700z with turion 64 x2 @ 2.4 Ghz, things went smooth. no heat issues. it just varies from notebook to notebook.

@Mantikos
though i've given the current dv5z back to the store, they're saying they'd get me another 1050ee in a week (as it's not available in stock). so it's all good now

thanx for all your support.

 

Hi, I have a similar problem with the dv5-1160eo, also the AMD Turion X2 Ultra. Bought it 4 days ago, and in windows with no programs active it measures between 60-65 C and while Im playing it reaches 90-94 C and the performance gets rubbish! I Phoned the HP support and they told me that this wasn't a game-computer (the game I played was WC3!!), but I could try to update my drivers for the graphiccard, when it is the CPU that is overheated.. Need Help aswell!!!

 

dude, no matter what your laptop should not hang around 60 degrees celsius even if the laptop is not raised up at all. I don't know though. I think Im lucky cause my idle temp was 44 degrees celsius before my OC as you can see below. Now it idles at 52 degrees on performance mode and when I play crysis for an hour it gets to 75 degrees and never goes over...

 

The bad capacitor problem described in this iMac G5 repair tutorial made me think of this HP overheating problem:
http://jimwarholic.com/2008/07/repairing-apple-imac-g5-motherboard.php
Basically, bad caps in the iMac's were causing instability, failure and excess heat generation. Replacing with high-grade caps fixed everything and made the system run much cooler. Usually the caps were on the motherboard but often in the power supply too. Either case would cause high heat.

I have to wonder whether they used bad or simply low-grade capacitors in the 90W power bricks? If your brick gets hot, that's a clue. If not, then maybe on the mb? My dv4z's 65W brick is barely warm at the moment and the notebook itself stays reasonably cool.

Could any EE's here enlighten us?

 

Your statement is incorrect about the dv5z. High temps. are normal for the z. Puma is the easy bake oven of the dv series. I'm running at 63 C with just the internet running and the max is 82 C when I was running virus scan.

All the vents are clean and clear and the notebook is sitting on a clean, flat, wood surface.

I don't game, but if I did I could probably heat my house with this notebook.

Not too worried about the heat as I have a 4 year warranty paid for by HP.

 

52C on my dv4z (Turion Ultra ZM-82), with a couple dozen Firefox tabs open and various stuff chewing up CPU time. The dv5z should run cooler if anything, same CPU and GPU in a larger case, so I have to wonder what's going on.

 

here is my hardware config if anyone wants to compare

dv5z replaced a dv6870us that had a TL-64 and the 6870 was an ice cube compared to the dv5z.

My gpu is different than the gpu in the dv4z, but my gpu runs <50 C so that is not the problem. The zm-84 and puma power management is the culprit.
