dell m1330 cooling

I have the dell m1330 for 3 years. I change the motherboard once because GPU overheating problem (I used the warranty). Now I dont have warranty, I made the copper mod so the temp downs to 58 C idle and 80 C gaming. So it is running smooth after the mod. Still I want it to run cooler, so im going to put another cooling with fan over the gpu. But the new cooling needs 12v for the fan, from where in the laptop I can take 12v??? usb??? or in parallel with the stock fan??? or from the AC adapter???

 

bump! anyone? I know this not is a simple mod but anyone knows or do a strong cooling for a laptop? No cooling pads please

 

You can try modding a USB cable to a 12v fan, plenty of examples on Google. But those temperatures are way too hot, and the GPU will fail again with those temperatures. (I believe 60-70C full load will start to cause it to desolder).

 

well the normal temps in my laptop are 60 to 70C and the fan not activate on high until it gets 75-80C and the fan goes off on 55-60C (I never gets under 55C because where I live temps rarely goes lower 75F) normal temps here are on 80s. The GPU clocks down when it gets 100C. Not is a good idea to up it to 100C on load. Thats why I want to do a good cooling mod including the copper mod I ready made. I dont want to get it higher than 70C

 

I will check that thanks Tsunade

 

I buy the parts, I will do it and post here the mod and the temp diference.

 

Here are the pics

 

still I need a switch for the fan. Still idle temp are the same (55-59C) because the Laptop fan dont start at this temp. There are a program to control PC fan speed? Because the new fan is only for complement the PC fan under overcloacking or heavy load.

 

I turned on the Laptop fan with Dell Inspiron/latitude/precision fan control. Put it on high and also have the second fan turned on. Running Fur mark on extreme burning, benchmark. (Core: 400, Mem: 601, Shdr: 800)

Starting temp: 56 C
After 5 min.: 65C and CPU: 41C
After the test end: 53C and CPU: 32C

Room Temp: 83 F

Same test without mod fan. Max GPU Temp: 64°C
now im confused. more tests soon.

 

Wow, that's interesting. Can you have the laptop sitting on desk flat with the 9-cell battery or do you have to have it propped up more?

 

I need to up it more, Im thinking on getting the rubber patch that uses the chairs to up it more. Currently im using belkin pad and it is curved so I dont have problems with it. Still testing the fans. Is interesting how the temp on load can change a lot, like 10 C of change if you are outside at 85 F or if you are inside at 70 F. So place temp is important to overall laptop cooling.

 

I was overcloacking GPU to 400/1000/750 with only laptop fan on high. Temps not go over 70C gaming. 70C doesnt go too hot on the aluminium of the mod fan, so thats why I think that the fan doesnt cool enough. Also the heatsink and the same mod fan in off brings extra cooling. I think that a good heatsinks maybe without using fan is enought to proper cooling. Still im thinking in the aluminium between copper pipe and the copper mod is making a huge stop to the heat transfer, the GPU temps double the CPU temps.

 

OC: Core:403MHz - Mem:900MHz - Shader:1000MHz

Without mod fan:
Max GPU Temp: 88°C

With mod fan:
Max GPU Temp: 84°C

Now I see a difference, still I think that the mod fan can take more heat from GPU because it aluminium never gets too hot. So it is blowing a lot of air to a surface that never gets too hot, between the GPU at 84C and the fan at ??? (not to hot to the touch) theres a big difference. Maybe in the future I will remplace all the cooling with a new modded cooling using desktop afterparts.

BTW 84 C at Core:403MHz - Mem:900MHz - Shader:1000MHz not is bad in m1330. I need another driver to up core clock because I tried to up it but rivatuner downs it to default again.
