Questions about notebooks coolers (custom made)

Guy's, I have a couple of questions regarding notebook coolers, especially the custom ones. Sorry for some words that you guys can't understand.

I want to do a custom notebook cooler to my laptop (Gateway P7908u), and I am thinking on using a couple of 120mm coolers, but I don't even have a clue of how to do that. I know what it would look like, because I want to place the coolers under the vents, and the base don't have to be anything sofisticated. But how would I power it? I am searching a lot on Google about it, and I won't stop until I learn to get it done.

But the main question is: can the notebook cooler damage the notebook? I mean, if I use 120mm coolers, would them "force" the notebook own cooler to rotate faster, degradating it faster, or breaking it in any way?

I mean, if my cooler is working at it's max capacity, and if I turn the cooler too at the max rotation, could it damage the notebook own cooler? Also, you guys who use it, does the notebook cooler make the laptop dirtier, with more dust? Couldn't I make a filter on the notebook custom cooler?

Also, here's what the laptop vents would look like:



I heard that the best notebook cooler out there is the Cryo LX one, but as looking at it I thought it was so simple I could make it... or am I wrong? Custom coolers are better than the Cryo one?

Oh, and if you guys can look at the picture, it seems that the HD has it's own vents, would it be bad to place coolers under those vents? Would it make the HD more dirtier, same to the other components, such as the rest of the laptop interior?

Thanks for the help guys, and sorry for any mistakes with my english!

 

If you want a good platform to work with, check out IKEA. They sell a nice laptop stand for like 3 bucks and it looks like it's begging to be modded. As far as powering those 120mm fans, I would use an external power supply. Those fans can run at 5V or 12V, but at 12V they will run at capacity and move much more air. At 5V using your notebook's USB ports, they will hardly spin much. Check out my post below for ideas. I used an external power supply from one of those cheap USB-SATA adapters for hard drives. It is rated at 12V, 2A so it has enough juice to really spin the fans. Then I used a voltage regulator to control the RPMs. Good luck with your project!

Thanks for the tips kosti!

I'll use an external power supply for sure.

But as for my other question, could the 120mm coolers damage the notebook coolers, as I said on the first post?

Thanks!

 

Anyone would like to give any tips or suggestions?

 

I do not think that the coolers will damage the internal cooler(fan)on your notebook.Of course,they might provide more air,which will cause the fan to spin faster from it is supposed to,but there is a bearing on fan,which helps it to rotate smooth and fast.Your fan might fail,because it will be force to rotate faster,with the upcoming air that your custom cooler provides.

But it should be safe,unless it your internal cooler in your laptop(fan) does not spin always at full speed.

You do not need to place your cooler(fan) directly into your laptop's vent.Just place it a little further away,I mean not left or right but a little down.That should make it safer.

Also,you can not make a dust filter,since it might decrease the cooling efficiency,sooner or later your lappy will be filled with dust,so dont worry.Just clean your room and desk,so there will be less dust.There is not much things to do to block dust build up yet.

Good luck,and I believe that usually Zalman NC2000 and Cyro do better cooling that custom made coolers.I strongly recommend you to get a Zalman cooler,since it blows air to all the surfuce of the laptop,which you need because your laptop has many vents and Zalman NC2000 should be a best fit for you.

 

Thanks a lot for the info lappy!

Well, I bought 2 Master Cooler R4-L2R-20CK-GP, I'll test and post the results.

But something came in mind: wouldn't it be better to use smaller coolers, aiming ONLY at the air entrance? I mean, with 120mm there's gonna be a lot of air flowing at the borders of the air entrance, wouldn't it be worse than using a cooler to perfectly fit the notebook's air entrance cooler?

Thanks guys!

 

Unless you attach the fan to the vent itself or make a shroud that directs all the fan air directly into the laptop, there's going to be loss. I wouldn't worry about it. It doesn't hurt to push air over the rest of the base.

As far as damage from fan over-rotation, I would think that since you're pushing air in, temps should drop and the fans should spin down. If you speed em up a bit, they're probably still spinning slower than max RPM.

just speculation, though.

 

About you said, it was about the bigger (120mm) coolers, right?
