Hi everyone! I just solved my Asus problem!

My notebook just turned out one year old. I was just about to buy a notebook cooler because of too hot temperatures. The processor, Intel Core 2 Duo 2,16Ghz (T5850) was going +85c and the processor was automatically forced to underclock while I was gaming -> choppy and bad framerate.

I had a can of pressurized air so I popped the fan/cpu/gpu hood and sprayed the dust off. Not too much dust came out but I was glad there were some puffs of it. Then I cleaned the fan with some cotton sticks dip in a electronic cleaning solution. I screwed the panel back and started my notebook. Now the core was max 82.5c when stress tested with Prime95.

So I googled some more about processors – and came across UNDERVOLTING and RMClock. Now my processor runs 0.125V lower than the CPU default and IS STABLE + temperature is 78.5c while stress tested.

Here’s a guide to lower your processor voltage safely!

This might be an old thread but I have to say this. I have a 2007 MacBook with a Core 2 Duo T7400 similar to your T7200. You said 70 Celsius after gaming? I would love that temperature. After gaming (at the lowest resolution possible) if you look at my Mac in Boot Camp temps are more like 90-100 Celsius. I have gotten it to above 100 Celsius. Idles at about 60 Celsius so I have gotten used to the heat.

I have to subscribe that opening up the back of the case and cleaning up the dust accumulated help tremendously with the temperature of laptop, if initially it was constantly staying with little load at 65-70C, now never steps over 47-49C, amazing

I found my ASUS m51s laptop was having the same issues as this.. I ended up taking my notebook apart. I found that the computers cooling system had been clogged with dust. After cleaning and re assembling the laptop ran great and I havent had any issues since. The main problem was that the cooling system is like a metal sleeve that connects to your graphics card and your processor. I eventually cleaned out the back sync which was allowing air to pass to the outside of the computer( where all of the dust had collected ). Hope this helps guys and good luck!

I highly recommend no lower than about 20 degrees Centigrade. It really depends on if the CPU’s interior can be much higher than the surface. Try a little experiment with an amp on a cheap radio to see how long it’ll work with dry ice on it. Semiconductors become resistors at too low a temperature. Also, condensation of water vapor isn’t exactly a good idea inside the case.

My Acer laptop was starting to run very hot especially the GPU so i have looked at cooling fans but not been impressed by them especially the position of fans.

Had a brain wave! i always have the cool bricks from a cool bag, if you know what i mean, and i placed 2 under the machine making sure the vents were not blocked. Result GPU went from running at 89 degrees to at the moment 5 or 10 minutes later 66 degrees and still dropping. The cpu was running at about 70 degrees and is now unbelievably 48 degrees and still dropping my machine is silent no fans running at all and more importantly running really well.

Now engineering hat on I need to design a cradle, with fans which are adjustable in position so to direct air where I need and a mounting below the fans which will let me secure the cool blocks below the fans so the air being blown into the machine is very cold.

Now question is there a temp which would be deemed as too low?

Some interesting posts here. This was my experience with a Fujitsu Siemens laptop I finally discarded earlier this year. It was nearly 3 years old and was prone to crashing once every day or two. The CPU used to run in the 60 degrees Celsius plus range all the time. Whats interesting is that the graphics card (ATI Mobility Radeon 9200) was actually the one generating most of the crashes. When the GPU finally failed I got rid of the laptop. I now use a notebook cooler with my new notebook and that drops the temperatures of the CPU and GPU by about 10 and 5 degrees respectively, which certainly helps in the middle of summer. I’d definitely advise people to get one.

For any Notebooks, I highly recommend the Zalman Notebook Cooler. It not only cools the laptop but it also allows you to use it on different surfaces and slightly elevates the laptop. I have noticed cooler idle temps with this one already. I use it with my Asus G1SN. I also use a Laptop cooling Mat from Newlink but this is not as effective.

I had issues my notebook as well and when I checked the temps initially using Speedfan, I was shocked to see it was running at 70C+ then I read somewhere that the normal temp was at 60-80C. Then when I installed NHC (Notebook Hardware Control), the temp of the CPU was displaying at 60C. So which one do I rely on now? SpeedFan or NHC???

I’ve had trouble with my laptop overheating, It’s just over 12 months old and like the post before I opened up the bottom and cleared the dust out. It has gone from 80-95 C to between 50-75 C at full load, I strongly suggest checking for clogged dust in the fan if your laptop is over 6 months old- I use ‘Notebook Hardware Control’ which monitors temps of my HD, CPU and GPU I’ve found it very helpful.
