Asus z70Va heat problem

Thread Starter 
im getting tinitus here while playing wow. ive even locked the cpu to 800mhz and declocked the GPU to 200/175. its dosent help much though, once i plug in the AC the temp go from 60 to 81-83 (right below the buttons, ESC, F1-F4) which im guesing is the GPU.. im not supriced that the pc gets hot if i play wow, but im really amazed that the PC, while idling on AC, feel like a nuclear reactor within 5 minutes.

any reason why the GPU go bezerk when AC is plugged in? do you feel the same increase in heat on the bottom of the PC in the top left corner below the ESC -F4 button?

once i unplug the AC the temp drops in seconds.

When your on AC the processor runs flat out, on batteries it's throttled back to save power. Hence more heat on AC. Get a free app called Notebook Control. Set it to dynamic switching on both AC and battery. This allows the CPU to throttle back when not being used but ramp up once it's required. Now tweak the voltage requirements. My V6V used to idle at around 65 degrees and I have seen 88 when gaming. But after a tweak of the voltage, I got it down to 50-52 idling and can't get it above 70 degrees when flat out!!!! A MAJOR drop in temp and it's a stable as a rock.....

Hope this helps...

thanks but i already did this long ago, i do have notebook control and as i said ive LOCKED the CPU to 800mhz (0,700v) and LOCKED the GPU clock to 200/175 and they really stay there nomatter what i do or play but still, once i plug in the AC the notebook start heating up, if i then launch wow the GPU fan gets really buzy.

Instead of using NHC to clock down the GPU, go into the ATI driver settings and change the PowerPlay setting for AC from 'max performance' down to either 'balanced' or 'optimal battery life'.

My understanding is when it's on 'max performance' the power optimizations aren't used. I didn't do any thorough testing, but just from the discharge rate reported by NHC, even when manually downclocking to lower clocks then the 'optimal battery life' setting, the notebook consumed more power.

If you change the PowerPlay settings, you'll want to change it back to max performance when you game.

If you want greater fan control, use Speedfan to manually control the fans.

okay ill look into the driver options.

speedfan is good if the PC is not pushed. but for gaming speedfan is not good, it just set a treshold and once that treshold is crossed, speedfan put the fan into chopper mode. the built-in fan control is better because is a 3 step function i think.

When I did the speed fan thing using the setup described in "ultra quiet cool" thread I went from high gaming temps to not busting 75c GPU on any game so far (mostly jedi acadamy - hl2 - css)

Try the speed fan thing. Unbelievable difference.

is there any way to not undervolt the cpu permanently? like letting the cpu ramp up when it needs the processing power?

ok so i am having trouble with fan noise also, let me get this straight:
speedfan - to control the fan rpm
NHC - to under/overclock cpu
ati powerplay - adjusts the power consumption for gpu

should i use all three to make the laptop quiet? sorry for the noob questions and thanks for your time!

I believe that is called "Dynamic Switching". Should be an option if you have Centrino Hardware Control

so it it ok to uninstall the power4gear once i get centrino hardware control installed?

The fan noise and heat was driving me up the damn wall lately so after reading this thread I stopped using Power4Gear, and installed notebook hardware control ... then I set both AC and batter to dynamic switching, then I installed the newest drivers and ATI software from the Asus site and used the PowerPlay options to cool off the GPU some.

Unbelievable difference ... My system went from running at about 78 degrees to 58 in a matter of minutes. Now its quiet and cool!! thank everyone so much, this thread is awesome, I like my laptop again!

Just a thought, I used 2 bottle caps to elevate the back of my Z70va (one on each side).
I did not notice any temperature changes (am using mobilemeter to monitor), but I do believe it helps abit on the ventilation as both fan intakes are at the bottom..

cheers !

kinda ghetto dude.... i use solid platinum pieces to raise mine
anyway if i installed speedfan and then started using CHC/NHC, are the speedfan settings still in effect? and would it be a good idea to reset the settings somehow? recently my laptop would complain about getting the cpu in the 95C range, so im thinking the speedfan settings are at fault, even though i followed the online "quiet laptop" thread to a T
