How to deal with heat

Hi girls and guys,

I did another article comparing the temperatures in 3dmark05 tests for combinations of cooling pads and undervolting. It was done on my notebook with overclocked CPU (Pentium M 1,86@1,96) and GPU (Ati x700 128MB DDR@400/400) using NHC graph abilities.

For those who still have doubts how to make the game fast and notebook cool - check this :

Cheers,

 

very good read! nice chart too.

i am surprised that your notebook blowing out the bottom, and your CP blowing up..still cooled effectively...also, i would test it out on other notebooks (a notebook that blows out a different direction has intake on the bottom..etc..)

pb,out.

 

Great deal thanks Ivan (I am a great fan of you )

One question: I have also X700 (posted you a few times) and I have an Pacific Breeze cooler...

So, when I play I cannot hear my internal fan going on (maybe few seconds in 5 minutes)... does this mean that my motherboard etc. is heating up? Because my notebook cooler doesnt suck hot air, it blows cold air...

So the only thing I am praying for is Notebook Hardware Control. They promised they will have ACPI support in version 1.2 I thought.
Because then I can let my internal fan go on too

One last (maybe stupid) question: How come my notebook plays very bad if my temps are 25 for CPU and 20 for HD?

EDIT: Mate how do you see your GPU temperature... I am searching for it 3 months now I dont think my card has a sensor for it

EDIT nr. 2: Ivan, I have almost the same PC as slap-0 at that site gamebooks.com... He can't read GPU too Did you had a solution for him?

 

Hi pb, Charlie,
PB:

First thanks. Actually CP is taking the air out straight around GPU. CPU is positioned 10cm away, and CP is 5 cm shorter than my laptop. That means that CP takes the hot air from the inside of my notebook, and fan takes in cold air just over the edge of the CP. That way it works OK.

I also tried the CP that blows the cold air up - and it was helpless. Strange but true. It was also made of aluminium. I did the test and was very sad. I returned it the next day.

Charlie, I didn't know I had fans! Cheers mate!

Is your fan working OK otherwise? If it does - don't worry it will start if it gets too hot inside.

I don't understand. You mean your games won't play fast if the temp is so low?

I can see GPU and Ambient GPU temperature in Home Everest. And only there. But I think you thought I put GPU temps in a chart. Actually in the graph there is CPU temp from NHC. GPU and CPU are under the same heatsink and that is actually the only temp that matters while gaming. It shows the combined heat produced and fan and CP ability to keep on with it. It is also greatly affeced by undervolting. Good point though (about GPU/CPU temp confusion) - I will make it more visible in the article.

No unfortunately, I think slap-o said that the temp was blocked somewhere in the hardware, because we have the same BIOS too and I can access it and he cannot.

Cheers,

 

That's an awesome article, you certainly made a great effort! I am hesitant to try undervolting mine . . last time I installed NHC, my fans didn't work at all, almost overheated. As soon as I uninstalled it, fans went back to normal. So unfortunately I don't think it is going to be possible for me. I might get gutsy enough to try it though, we'll see.

Thanks again,
Chaz

 

Hi Chaz,

I didn't mess anything with fans. You say NHC blocked your fans just like that? Strange.

I just wanted to show how undervolting + cooling pad can help a lot in a overclocked machine (CPU and GPU are both overclocked), and it is for example cooler than everything on default (and slower too )

Cheers,

 

Yes, your article on how much of a difference underclocking can make is very tempting to make me try NHC again. Mine can get a bit warmer than I like, but not dagerous. I do have a cooling pad (cheap one, but it works), so that helps a good amount.

Last time I installed NHC, I couldn't figure out why my fans wouldn't come on - then I finally uninstalled NHC, and my fans went on at the next restart. Very strange indeed.
