Zepto Nox/Mythos/Nexus max gpu temps

Hi there fellas.

Im looking for a kind person with either one of these notebooks (with 9600M) who can do me a little favour.. simple run furmark stresstest software with your laptop on a table with nothing lifting it.. Be sure to take stability test in furmark, and set extreme burning on, and AA to max. Then let it run and see whats the max temp it gets at.

Thing is, mines a 90 celcius.. I've overclocked it a tiny bit (the gpu) but with default clocks its not really any cooler than 2-4 celcius. If someone could do the stresstest and tell me their result i would be really happy..

Thanks

 

I know it's not the same notebook, but I just bought a Zepto Znote 7000.
I ran the Furmark Stesstest for 600 seconds and it topped at 68C, but the noise level is also higher on the Znote 7000 than on the Nox A15 a friend of mine has.
It seems like the Znote 7000 has a bigger and more powerful fan plus it has a bigger copper profile, but it is also a lot thicker in the barebone profile than Nox/Nexus/Mythos. Thickness and in noise level i like the Nox/Nexus/Mythos a lot more, but I'm just hooked on the design of the Znote 7000.

 

I have 78C - 87C tested with a Digital Temperature datalogger. So no software, because the software is not as accurate.

Tested with Mythos A15H 9650GT and P8600

 

So you wouldnt say 90 celcius is a "dangerous max" for a 9600M? I just remember once it was more like 82 at max, and i've checked for dust in the fan.. Hmm

 

When the GPU reaches 110C it will shutdown to prevent it from getting damaged.

 

If I can butt in, The 9800M GS throttles down at 110C as well, doesnt actually shut off though. Glad to see this temperature seems to be uniform in the dedicated 9 series, gives me an idea on things.

No offense to knowledge you might have that i dont. But the software usually measures from a sensor (thermocouple, etc) on the chip level which is actually a hotter zone then the thermal interface that your using the probe, infrared, or any kind of temperature measuring device thats not 100% in the same direct contact location as the chips own sensor.

Just my thought on that.

 

So its at 100-110 that the gpu takes damage? 90 Celcius isnt really in the danger zone? It'll make the life of the gpu shorter im sure.

 

If you install a new BIOS the software can easily give you other measurements. Same thing with voltages. We measure voltage on a MiniPCIe slot with a diagnostic device. If you run software like fanspeed you'll have a different voltage then with the Hardware tool.

We place 2 sensors. One on top of the heatsink, and one below. it cannot be more accurate I think

 

The hardware in the reviewmodel that I've tested was:

- Intel® Core 2 Duo P9500 2,53 Ghz FSB=1066 MHz
- 4096 MB (2 x 2048 MB) DDR2-800MHz RAM
- 320 GB SATA - 7200 RPM – Sata Hitachi HDD
- 15,4" WSXGA+ 1680x1050 pixels / Ultracrisp / glare-screen / Bright pixel garanty
- Nvidia Geforce 9600M GT 512MB DDR3
- Intel ProWireless 5300AGN 450MB

But the GO9600M GT 512MB DDR3 which you will find in the Zepto Mythos is a beast!
And it has a quite nice accidental circumstance: the temperature. You can read more about this subject in 'Temperatures and soundproduction'

The exhaust is on the left side of the laptop:

​

But you don't notice this while working in word or when you are internetting. If you are going to play a game you will notice a warm airflow leaving
the exhaust. I say warm, because it isn't hot. The highest GPU-temperature that I've seen when testing this Zepto Mythos was only 70°C. This was during a two hours sessions of Gears of War. My own Zepto Znote 6224W easily gets 100°C when playing a game! This could have a couple of factors: different chassis, different hardware, better airflow and so on, but playing a game with a maximum temperature of 70°C is very nice. Sometimes you will hear the fan, but that is only when playing games or during benchmarking

 

How on earth can they be so different? Nexus and Mythos should be the same thing basically shouldnt it?!?! and i hear the fan constantly (typical nox/nexus, noisy fan, we all know that) The fan doesnt really bother me and since Zepto is coming up with a new BIOS that should improve it, im happy.. I just dont understand how that mythos could have a max of 70...

Maybe i should get GoW and see if its the game

 

Sounds good, I was wondering if anyone had tried below the heatsink, while not ideal for cooling best results would be obtained without paste, while not being a perfect contact the paste would interfere with conductivity within a degree or too... i think.

I am personally nervous about going over 90C but what the real problem is, is the cycle. I run bottom off on a cooler because i dont go very far with my ASUS and it gets my GPU running in the mid 70's versus the high 80's up to 90.

Going from 40 to 77 (or from any temperature to another) materials expand and then when cool they contract. While they take into account of this in designing there is only so much they can do. A GPU that only under goes a 20 degree change back and forth will last alot longer then one that has a 40 degree change.

A GPU running slightly hot (at idle and then in gaming) but still enough under the limit might outlast one that runs a bit cooler but has a huge temperature change that happens alot.

Its all hard to say though.

 

OK so i just got my finger out and cleaned it again and this time it made a difference.. like a lot.. havent stressed it to the max yet but god its way more silent and keeps under the 50 when idle/internet/basic stuff..

 

I don't think this is an issue. Because your GPU and heatsink are decreasing in temperature very slowly. It is not that it cools down 40 degrees in a few seconds or minutes. I think it takes about 30 minutes to be at 0 C

 

Maybe not it was something we were discussing in the graphics area earlier this week. In my situation it jumps to around 70 VERY fast, and slowly climbs from there. It jumps from high 70's to 60's to 50 in about a minute. It takes several more minutes to get back into the low 40's.

True the slower it is the easier it is on the material, the general discussion my point came from was comparing desktop cards to laptop cards as laptop cards tend to have a greater range of temperature.

Only real reason i ever jumped in was when i saw that 110C temp. I had not heard of zepto before i have been on this site. Im a bit more open to other brand books. The pics i saw on page one look good and actually we had a guy wanting a squared off shiny laptop like a particular voodoo envy and we couldnt find him one. Wish i knew who it was id pm him about the zepto.

 

My own GO8600M GT goes from 80 degrees to 55 degrees in 2 minutes, no problems!
