external laptop EXHAUST fan

So, i have this FAN, a house hold fan that is about 8.5 inches in diameter, and a dell xps m1530. As we all know... this laptop gets warm. I have searched the web for an EXHAUST fan for a laptop but none show up (other than a wimpy one). What i am thinking of is hooking up this biggish fan to the laptop exhaust for uber coolage.

What i have in mind is make an airtight seal around the fan with something (dont know yet) and having it connect to the vent on the laptop almost air tight. I want some breathing holes so that it doesnt suck the all the parts out of this baby .

any words of advice, other threads that i missed with this, or design words of wisdom?

ITS SUMMER BREAK AND I WANNA SCREW WITH SOMETHING!

I am currently working on getting some pictures.
thanks

 

i dont know what sort of vent configuration the m1530 employs but if it resembles something like this: ||||||, then the Evercool NB-MA1 USB extractor fan might prove useful (esp. when you connect it to a 12v 1000mA wall adapter like i did!)

 

hook up fan so that it pushes air into the laptop, you will get positive pressure buildup in the computer...

all the dust particles will get nicely packed in there...

hook up the fan so that it pulls air from the laptop, you will have negative pressure in the laptop...

all dust particles will be pulled up through any opening whatsoever...

i don't think you really need that big of a fan with such huge cfm capacity to cool your laptop...

so what do do?
easiest is just to elevate the underside and provide for better airflow where it's supposed to flow...

get a cooler/stand combo... great... but can't travel with em...

i used a flip down laptop feet that served me well...

now with my dell, i just raise the bottom...

i may even consider buying a replacement bottom panel and open up the holes for better air flow... maybe that much... but i don't think hooking up a household fan will be a great idea...

go git yourself a bright yellow dewalt drill and go make something else...



oh, and if you're going to screw with something... yate loon just came out with a fan that connects to a 5v usb header... better than having to plug a fan to the wall socket... no?

 

its a ||||| and i have seen that nb-ma1 thing before. Does it go turbo when u plug it into a wall? half the reason i want to use the fan is because its big and awesome and free.

 

@12v: yes it does!!! It's real noisy at 12v too.

Been running it at that specific voltage for more than a year now; you get accustomed to the noise after a while....well at least i did. Alternatively, you can run it at 12v and then push the resistance button to lower RPM slightly and kinda get the best of both worlds (still pretty noisy though).

 

haha thats funny.

well, ill see what happens this summer.
thanks moto.

 

Since I will be building a laptop cooler for my computer, since it gets hot while gaming, I need to know, how do I hook up a couple cpu fans 2 or 3 haven't decided, to an ac adapter? Is there an ac female plug I will need to also purchase? would I need any resistors? Thanks.

 

If you use a big fan like you suggested you can actually do more harm than good by moving too much air. Stick with something small and mod that.

 

kk, thanks. ya, that was part of the reason i wanted to ask around. its not really my laptop so i didnt want to maul it lol. thanks

 

I would have to disagree,
My current laptop cooler has three 172mm in diameter EBM Papst fans which push a combined 1000cfm of air volume. After a year of using it, not one problem.
My laptop runs very cool with it

Before that cooler I had a more simplified cooler with two 6.77" ebm papsts which pushed about 1200cfm at a higher air pressure. Again three years of use and no problems.

I like the way my cooler sounds, so it doesnt bother me. It gets a bit dusty, but hey even with my heatsink clogged of sawdust and plaster of paris dust it cant even break 100F under load.

if you have space inside the notebook you could install a 6mm blower fan.
connect it straight to usb power.

small 6mm thick blower fan ~ $20
if you want I can give you a link.


otherwise, undervolting guide.

or change the thermal paste and clean out the dust.

 

lol thats hilariouse hahaha. idk, i might. dont want to kill the comp till i can get my own .

thanks guys.
