Custom Cooler Pad Help !

Hi everyone ! i'm trying to make a cooler pad very similar to the Cryo LX but using 2 of these :

http://www.newegg.com/Product/Product.aspx?Item=N82E16835706015

Noise doesnt matter since i used to play in my room and using a plantronic headset ... what's your opinion for this crazy idea should 2 of these freeze my notebook with their 252 CFM Air Flow ?

Thanks !

Also i wanted to prepare another one but for playing @ LAN maybe using 2 Thermaltake A2029 @ 75 CFM with 25 dbA .. playing at LAN with a 65 dbA will cause the people around me to cut my head =(

 

You can do it all right, but you need at least a 100 watt power supply. Those fans consume a lot of power. 4.8 amps each = 48 watts per fan.
They are good fans, Delta has pretty nice stuff. However these fans are going to be loud over your headset.
If you are set on those fans, get a 9V power supply rated at 80+ watts. That will keep the fans at relatively high speed, and still maintain alot of airflow.

You will need to make a mount for these fans, you cannot put them down simply on a desk. You will need at least 3 inches of space under the fans, as to not generate turbulence.
You may find a better alternative to use 120 mm fans rated around 100cfm, as they will be quieter and require much less of a power supply

Check out my laptop cooler, it has 1000cfm of air volume:

Make sure to get fan grills,
I still dont have any on mine, my laptop fans in that video ripped the toenail off my big right toe. It hurt quite bad.
Needless to say I do not put my feet ontop of my refrigerator anymore

Thanks for your recommendation ! i was thinking of feeding both coolers directly to AC.

Another point .. what do you mean with turbulence ? my idea in fact is to mount them on a very similar surface like the Cryo LX ..



just imagine that i will replace both Cryo's cooler and put 2 of those or maybe 2 @ 100 CFM , i'm thinking about a system to replace them easily in case i want to use the 252 CFM ones or the 100 CFM.

 

Do you know what two fans at 66 decibels sound like? A turbine jet engine lol. You will hear it through your headphones.

Buy yourself two of these adjustable fans and it will be more than enough to cool your notebook

 

Turbulence meaning this:
Grab an ordinary fan and power it up
Put a piece of rigid cardboard 1/2" from the intake side of the fan. You will notice the sound change quite drastically, you will also see that the output air volume gets cut almost in half. That is because you are choking the fan on intake air.

You need to find the distance where your fan is not choking itself or causing intake turbulence. That is the point in which you get maximum air flow, and maximum static air pressure.

You may want to look at these: 336cfm in the 120mm package

And by plugging into AC, you mean, you need a AC to DC power supply

If you want to simply plug the wires from the fan into the wall socket, you need 120mm AC fans. I am not sure if Delta makes them, but I know EBM Papst does, I own a few. Make sure to get Impedance Protected fans if you go the AC route

excellent i think that with a distance of 8 cm's it will be enough for the 100 CFM ones (maybe less here) and for the 262 .. and my idea is to plug the "custom cooler pad" into the wall socket as you say.

Here in Argentina i can get easily the thermaltake Blue-Eye LED Case Fan of 120 mm @ 93.7 CFM, do you think that 3 or 4 of these will be enough under a surface like the Cryo LX ? to literally freeze my notebook ? =)

My idea also is to prepare the aluminum surface so one of the coolers will be positioned in a way that impact directly into the NB air intake

 

No matter how many fans you have, the coldest your laptop will run is room temperature. It is a challenge though to get all of your components running at room temperature.
With ~1000cfm on mine, that is not possible.
It runs very cool, barely breaks 100F under 100% load, so I am not complaining. 100F under full load is a whole 45F colder than it is without the fan cooler.

By the way, AC fans mean you can plug the wires of the fan directly into the wall.
DC fans mean you will need a AC to DC power supply. these can be cumbersome if you are carrying it around.

You can run a google shopping search of 120mm AC fan , and you will find a lot of options

Do you have 120VAC or 220VAC in Argentina?
It makes a difference whether you buy AC fans, or DC fans.

Thanks again ! Which is the best temp you get with your cooler pad ? 45F under Full Load ?

I have a P7350 2.0 running idle @ 55F .. how much do you think i can lower temps @ 2.4 ? games oftenly don't stress to much the processor, but here thep problem is the GTX 260M in fact that reachs high temperatures and i can't overclock it properly with those temps (maybe 90ºF)

Here in argentina we have 220V AC , my idea if the fans are 120 is to use a 120 to 220 transformer.

 

Well my laptop has fan control software. So internal fan control drops peaks from 165F down to 145
My cooler drops it down to a max of 100. So a delta temperature of 65F
But that is just the processor
a good cooler will drop temps of the harddrive, memory, graphics, etc.

If you are going to overclock your processor, you are going to generate more heat. So say your 25 watt tdp jumps to 28-30 watts. Having a good fan cooler will make the temperatures under full load much lower than the laptop at stock speed with the stock cooling.

You can buy 220VAC fans. That is the easiest thing to do in your application.
All you would need is to wire the fans directly to a 220VAC plug.

Here are some decent fans:

All you need are the fans, something to mount them to, electrical tape, a soldering iron, solder, wire stripper, and a male plug to go into the AC socket on the wall.
It shouldnt take more than 15 minutes or so to wire the fans up. It is pretty straight forward. The chassi you mount it to will take a while to make, depending on if you make it out of plastic, metal, or wood

Gotcha =D i want to use Aluminum .. i was thinking of emulating the SAME model like the Cryo LX but with cooper .. do you think it will give better results ?

 

Materiality will not effect temperatures.
Here is why
Your laptop shell is most likely plastic.
So even if you have a pure copper chassis, it will not conduct heat any faster than a plastic base. That is because the chassis is made of plastic

If you have an aluminum chassis, than the best you can do in terms of transferring heat is aluminum. Copper will offer no additional heat transfer, since the source is aluminum

K-TRON

 

i thought that when the air flow is pushed through the aluminum surface the temperature of the air decrease a bit, after all the aluminum allways stand at very low temperatures.

 

Well technically it could, but I am not sure if it will.
I do not know if it would be even a degree or so difference.
You might as well try it, there isnt much to loose

Make it out of aluminum, since copper plate is usually a ton more expensive

K-TRON

 

here is not so expensive .. i think that a plate of 40 x 50 @ 5mm thickness was something about $80 (u$s 20) but is quite heavy and if this "theory" is right the aluminum is far more cold than the cooper to transfer air.

Thanks for your help .. btw .. do you recommend 4 or 3 of those 100 CFM coolers ?
