Dealing with high temp. What are you doing?

Well guys, I don't know how have you been doing with the temp of your lappy, but I've had a small headeache with mine (see my spec in my signature).

I recently bought a new cooling pad. I used to have a Fanless one and temp were 60-65 C degrees running at high performance power plan and running basic programs (Outlook, IE, etc.) and up to 80 C degrees when gaming.

Now I bought the Zalman Cooling pad and I cannot say that difference is great. The Temp keeps running the 60-65 degrees and when gaming it reaches 78 degrees and the HDD 50-55. It's too hot for me, I decided to use the HP Recommended Power Plan When Plugged to AC. Right now as write this thread my processor is running at 798.11MHz The CPU Temp is 54 deegrees (All degrees here are in Celcius) GPU 54 degrees and HDD 40.

I'm running Outlook, PC Wizard, Windows live mail, Bitdefendet Total Security and obviously IE7 wit two tabs. Changing my power plan was the only way I could get lower temps. Whatt about you people? How are you dealing with the high temps on your dv9000's series?

 

for your processor, you could consider undervolting. you could also get your gpu to underclock when you are not gaming (if it isn't already doing that)

 

Isn't that dangerous. And anyway, how can i do it. (For both CPU and GPU)

 

No undervolting is not dangerous at all, overclocking is. Worst case scenario is a Blue screen. You could easily cool off 8c and gain 20mins battery time. I managed to take that much off with just small changes, i could have easily lowered it more.

No it doesnt slow down your performance at all. All processor chips were made to run at a standard voltage, so intel doesnt have to individually tune each chip to their optimal voltage. They actually can tollerate lower voltages about .200v less for most chips. I only volted mine down .150v and manage to take off 8c off my max temp

Thanks, I will be checking that.

 

i believe that we have a guide or two about undervolting. just search for it. one from ikovac and one from chaz....but both using nhc. i prefer using rmclock personally.

 

I like to use RMClock to undervolt or NHC.

 

I have a dv9030us and a dv9260us both running on Zalman Cooling pads since they were purchased. When the Zalmans are set at the medium setting, the notebooks hover between 38-45C for both when plugged in and on Maximum performance power profile. Since the Zalman have a smaller footprint than the notebooks, I position the notebook left edge on the left edge of the Zalman. I hope this helps!

 

Thanks mckinneydij. I tried that too. But was not pleased with the results. I even placed something under it to lift it a little bit and it has done something to improve better temps but no that much. What I'm some happy with is with the undervolting stuff (je je je), but I noticed this: Although temps level were down 10 degrees Celsius (YEAHHHH), I see a discrepancy between SpeedFan and RighMark CPU heat meaters. SpeedFan display Core 0 and 1 with 29 degree C whereas Right Mark display 42 degree Celsius .

Another thing is that when I unplugged it from AC, the cpu frequency was set to 1.10 MHz consuming 0.938V and when using just the default power saver plan from my laptop, frequency goes down to 794Mhz using 0.85V. And I can't "undervolt" to 0.85V 'cause the lowest I can go with RightMark is
0.937V.

What I do is set RM to Power on demmand profile when Plugged to AC, and exit RM when running on Battery and set the default power saver that came with my dv9500t. What about you? Have you noticed any of this?

 

I used NHC with WinXP, but since going to Vista and leave my laptop plugged most of the time I have not bothered. Fortunately, the Zalman works well for me.

I would check again if your Zalman is working correctly and is placed on a hard flat surface, the fans and vents are clean in the Zalman and your lappy (I use a vacuum every week to clean them), and your fan in the back left corner is working correctly (video card). My room is kept at a cool 72F which helps. I believe your case is similar to mine and therefore is inherently bad for HD cooling especially the main drive bay.

Have you tried flashing with the newest BIOS and use a different video driver from laptopvideo2go?

If you have the means, I would buy the HP extended warranty with accident replacement, crank up the Zalman to max and let your machine fly.

 

1- My Zalman is new. Just 4 days old.
2- Yes, it's place on a flat hard surface (My desk)
3- Fans is working fine.
4- I don't know what's my temp in my room, but according to the weather channel web page my city's tem is 30 C = 86 F. I don't use air conditiones so you figure my temps. (by the way I live in the caribbean, Dominican Republic.)
5-Last time I flashed with the new BIOS update my lappy was heating more so I went back to my old Bios.
6- Last Video driver from laptovideo2go 169.28
7- I don't mainly use it for gaming, but I do play sometimes. I can disable RM if it compromise performance, but I;ve read that it doesn't. I'll probe that myself.
8- What would I need the extended warranty for? and What do u mean by "crancking up" my zalman to max? I use my zalman to max speed, is there a risk in doing so?

 

Ah! by the way, since I undervolt my lappy, my temps has steadily been as follow (using my zalman at max): CPU Temp 54 C (SpeedFan), the HDD 40 and when running the AV quick check 45 C. According to RM monitoring my cores are 46 C and SpeedFan says theya are between 30 to 36 C.

We are talking about a difference of 10 to 11 degrees celsius less. And I feel satisfied...a bit!!!

 

“In a computing context, ambient temperature is the air temperature of any environment where computers and related equipment are kept. Maintaining an appropriate ambient temperature is crucial to the proper functioning and longevity of computer equipment. In general, a safe range is between 60 and 75 degrees Fahrenheit, although the cooler end of that range is better. Ambient temperatures above 80 degrees make it difficult for a computer's cooling system to keep it at a safe operating temperature.”

Your Zalman would work MUCH better if the temp. is in this range.


What I meant by getting the extended warranty is if you continue to run temperatures that high, your lappy will have a much shorter life span. The basic warranty is only 1 year.

I hope this helps you out.

 

Great. I'll keep my romm cooler then. What do you think about my actual temps. Are they ok?

 

It's important to keep HD temps well below 55C.

As for CPU temps there is a thorough explanation here

If you plan not to undervolt for performance reasons, lowering the ambient temp and using the Zalman at max will help immensely!

May you and your lappy have a long and fruitful life together, Emedici! Stay cool!

 

Firstly dont use speedfan, everybody knows here its not accurate, it shows the temps for the other heat areas which gives you unbelievable low temps. Specially if you dont have the latest version.

RMclock shows the right temps, as well as HWmonitor and Coretemp. If you run these programs you will notice they all show the same correct temps

To undervolt with RMclock, you cannot change the lowest multiplier which is the idle voltage. Though you can go to the advanced settings of your power plan and change the Low Processor state %. Id advisee to leave RMclock on though

 

QUESTION: When you adjust the power settings (ex. high performance), those only count when you're on battery power right? When your computer is plugged in, all of your computer's abilities are maximized regardless of the power setting, no?

 

On default yes, but you can change the settings on either Battery or AC on any of the profiles. The only difference between the profiles is the advanced settings (sleep settings, processor state %, etc.). Look in the power settings and see for yourself at how it works.

I just leave mine on high performance, but i set it when i unplug the AC and go on battery power the screen goes a little dimmer. Also the screen & Hard disk will turn off after 10mins to conserve battery

 

Your settings are not necessarily maximized when plugged in unless you choose the "High Performance" power setting.

"Vista Battery Saver" can switch the power setting automatically for you when you go from being plugged in to when you run on the battery.

 

Yeah - I just noticed the advanced options to configure individual component performance when on battery or plugged in. I HATE how everything is so hidden in VISTA. Or maybe I was just so used to XP? And I just tried out Office 2007 ... EASIER MY ASS!!! I finally got Office 2003 down - now I feel like I have to learn a whole new interface. Why does Microsoft DO THAT?!?!?!

 

Where is this Vista Battery Saver you speak of? I keep having to switch back and forth from "HP Recommended" (unplugged) to "High Performance" (plugged in). You're saying that this "Vista Battery Saver" will switch it automatically?
