z70va heat

hey guys,

I posted a while ago about how my z70va has some abnormally high heat levels. Some people recommended opening it up to see if the heat sink was seated properly.

I opened it up and it *seems* like it is seated properly - is there a way to test this? you can't really look at it from the side since it's recessed in the notebook.

Also, is there supposed to be a piece of heavy plasticky tape on the edge of the fan and the two black blocks on the circuit board that are right next to it? I'm not sure if this would have any effect.

And I just checked in my memory compartment, and I can't even see the memory stick because there's this thin black sheet of plastic covering it in the entire compartment. Is this normal?

 

I'm not totally sure, but those COULD be there for warranty reasons; if your dealer sees that those tapes have been altered, your warranty could be voided.

Your post is about as detailed as saying " I just bought my brand new m5 and it has abnormally high rpm levels". I belive every dealer and reviewer here stated the following about 12 dozen times
Low load temp without undervolting should hover about 60-70C
Hi load can reach up to 90C. Although obviously prolonged exposure to 90C is probably not good for your laptop you can certainly enjoy hours upon hours of gaming or rendering without worry. Running your prime95 24/7 or while not in use to test the laptop is a bad idea. Unless you have temperatures which exceed the above you should not repost this again. Btw you see that sheet of plastic becuase there is no ram in that compartment. That sheed is meant as "insulation". Am i the only one who finds this funny? I am too tired to laugh now. This has gotten old already

 

low loads can hit up to 70C??? Ionno Eddie, Ionno. Seems kinda high to me.

When my baby was running without any power management program or voltage modding she never hit 70's...dang. I guess she's running nicely

After voltage modding my baby never exceeds high 60's.

Cheers,
Mike

 

On ac adapter on low load without undervolting they can and the will reach up to 70C. It all depends on ambient temp, the actual usage some may have alot of stuff in the background which makes the cpu hover at like 4%. On absolute low load you will hover around 60C thats base. 70C for low load is still low. With 90C being tops for hi load. You lonno becuase you are a freak for cooling. If you gave your laptop a chance to be a base laptop and run it like most people you would know.

 

I dunno...I think 70 for low loads is a little high... for ANY laptop. 50-60 is reasonable...but 70 is too high for LOW loads.
I think 70-80 should be normal for high loads.

 

You are generalizing. Yes 60C on low loads is what it should be under the right conditions. Here are some things you have to take into account
1. The ambient temps. You dont know it can be 80F inside this persons home.
2. The surface it rests on. He can be using it on his couch
3. Who assembled it. I would like to think most dealers are responsible enough to refill the thermal pad if the heatsink was reused or used to test for ghosting befor or some reason that allows for thermal compound to be removed.
4. What background apps. Most people here are knowledgeble enough to notice that they have peak loads at times when there should be no load. Stuff like malware can and will take advantage of your system to spread itself. He can be running multiple aDawares and antiviruses in the back. He can have alot of things that prevent the cpu from idling.

I will not assume that everyone knows how to use their laptop so i have to say that 70C is very normal for low load. 70C is not overheating. Its not hott. Yes it can be lower at low load but until the person confirms that 1234 are as they should be theres really no sound advise anyone can give him except to verify the above info does or does not apply to him

 

If that fan is coming on when it's supposed to, I don't think 70 for normal load is right....even in warm conditions.
In the summer when my house was like...90-100 F, the CPU in my M6Ne never even went above 62C (no undervolting, Speedstep ON, and FANS OFF).
So if the CPU fans are indeed running in these Z70Va's, I find it hard to believe that these systems should be running so hot.

 

sorry Eddie I will have to agree with AuroraS on this one, and it's not because I used his signature format

I know you build computers for a living and deal with 'em non-stop, BUT I would have to say for LOW-LOADS 70 is high. I would say for medium loads 70C is normal.

Yes it all depends on the ambient temperature. Yes I have used my laptop without any settings modded and I never hit 70 for LOW-LOADS.

Actually it was kinda good using my laptop without any modding, since I didn't have to worry about anything like temperatures because i didn't know them haha.

Cheers,
Mike (cooling freak)

 

In an ideal situation you would both be right. However an ideal situation can escape many people as i said above in which case you are both wrong. Me buildingmany computers has nothing to do with comon sence. Comon sence says. and i am quoting "an ideal situation means that the pc was aseembled right and there is no malware that prevents the pc from idling and ambients are normal". You cannot apply an ideal situation to any one user unless the user specifically says that his laptop is being used as it should. Until the person above replies and says yes i am ok with #1 2 3 and 4 there is no reason for you guys to make him worried becuase his temps are within range. He is not overheating. The only other thing that can be wrong is a microfracture in his heatsing which allows the compressed gas to escape gradually and get worse and eventually overheat up in the 100C. This has happen on m6n's a few times and any othe rnb that uses heatpipes for cooling.

 

the only heat aspect of my z70va that bothers me is the hard drive, cuz when it gets going the bottom is HOT. other than that, my cpu temps hover around mid 50's under normal usage and in the 70s to low 80s while gaming. only thing is the temps never really go back down to what they were at afterwards. afterwards they'll tend to hover in the high 50s to low 60s.

 

Those are pretty low temps fpr stock z70va. 50C is in the low range but you are probably undervolting. I can only say that the manufacturing proccess of the heatpipes is responsible for the variations we see with identical units. Identical meaning stock os load no other utils no other background apps. The heatpipes contain either some kind of compressed gas or liquid. Manufacturing proccess is always different. I dont know who makes the actual heatpipes for asus but i would say thats what causes differing temps on identical units in identical conditions. One month the heatpipes will get you 55C 2 months later same unit same specs same environmentals will get you 65C. Some people have been complaining that their lappys get up in the 90C range. Thats a bit hot but not overheating on prolonged hi end use but perhaps a replacement heatpipe can get it down another 10C. These heatpipes can break due to microfractures or other unforseen defects. I ve seen this a handfull of times on various units in particular the m6n models which were end of life sometime early this year.

 

To Everyone that posted about heating problems and differences. Where did you buy your Z70VA and is it using a stock thermal pad, AC5, or Intel Thermal Compound?

Thanks,

AC

 

The type of cpu also has a play in this situation. For example a 1.6PM will run alot cooler then a 2.0PM due to different voltages. With a 2gig i would say 65-70C woudl be normal under ambiant temps of 72-78F. But if the person was using a 1.6 that would be on the hot side. Also the video card depending on if ATI power play is on or off will make this lappy heat up alot. I have noticed with the lappy on 800mhz or even 2gig and power play set to low the cpu temp can drop 10C or more.

 

It does not matter what thermal compund is used. AS5 vs the base compond can only mean a variant of a few degrees tops if any. This has been tested many times before. The main difference between identical machines with identical environmentals is the copper heatpip itself.

 

I would have to agree with eddie on this one, and this is a shot in the dark, but I'm guessing Intel's don't respond as dramatically to different thermal compounds as AMD's because AMD's Athlon series had exposed dies and the compound was applied directly, but Intel's cpu's have a cover to protect the die from being crushed.

Also like he said mobile cpu's run on much lower voltage than desktops so thermal compounds shouldn't be an issue, but of course it won't hurt to go apply some AS5 to your laptop. Only thing is unless you apply it correctly you will have to reapply at a later time as the compound may not be as effective if not applied evenly throughout. With "straight from factory" thermal pads that is not an issue.


Eddie/Justin, some feedback?

Well, if you hang around this forum a lot you probably notice that i always post that i CANNOT hear my fan on every post and it's soo silent. Now here's the funny thing, I installed speed fan and everything was detected and all; working fine. Here's the catch, Fans are registered at 0rpm. ALl of them. And when it kicks in once in a while, it shows as 2435 rpm. 0_o so does that mean my hearing is still good?

temp ~40-50c on low/med/high usage.

 

haha i'd be more concerned if u were hearing things when the fans were at 0rpm , tho at 2400rpm the fans should be faintly audible at least.

 

aphirat you should be able to hear the GPU fan at 2435, it is noticeable but not overbearing...it is kinda quiet so maybe you just aren't listening for it that is why you couldn't hear it?

Trust me it's better that way.

If you wanna test your ears out go see a doctor

Cheers,
Mike

 

I hear it at 2435 if the sound is off ^_^.. but if it report 0.. it really is 0 o_0.. now what's cooling my machine all those time then cauz the fan rarely comes on.

 

Really? Whoa...either your undervolting is working amazingly with your cooling or maybe something is off?

Are you using SpeedFan to customize your fan speeds or just running auto?

Shouldn't be off all the time if you're using your laptop plugged in, but if you can't hear it while it's in battery mode that should be fine.

If your temps are fine then no need to worry, but be happy you lucky bastard~!!!

Mike
