An admittedly stupid and funny-sounding question about notebook coolers

I have an HP 9000 (17") that I need to cool off. Propping it up off the desk is insufficient. I've looked all over but there are very few coolers on the market for 17" notebooks. Also, I want one that I can power from a wall outlet. I don't want to power it from the USB, since that would just make the PC's guts have to work that much harder. I'm trying to protect my notebook, not make it work harder.

So, I think I may just end up having to make my own with a couple of muffin fans.

Because I've never had a chance to examine a "real" off-the-shelf-cooler, I need to ask this question: are the fans supposed to blow air up at the bottom of the notebook? (If so, I think they would be blowing air into the notebook's hot air exhaust and fighting the notebook's internal fan!)

Or are they supposed to blow air away from the bottom of the notebook?

Thanks!

 

different notebooks are designed differently. Some use the bottom vents as exhaust others use it for intake.

Building your own it wont be a problem because you can easily reverse the fans if you need too. I would recommend 120mm or 90mm pc fans, from there just design your base. As far as having the computer run it. Its not hard on the computer usb ports supply 5v of power and are designed to do that. its not going to stress the system out. However using an external power supply is good becuse if you want more power you can have it. pc fans run at 5-12v usually. Just get a pc fan controller or make one and your already past 1/2 way there.

 

stand in front of a fan. cool? yes. stand behind it. cool? no. your laptop is no different. the retarded engineers that made their cooling pad fans "suck the heat away" from the bottom of the laptop should be fired. you should point your fans at the intake of your laptop fan(s).
you are smarter than all of them just for asking! lol...

here's a funny thread i posted about cooling your laptop with a tablefan...

imho the best laptop coolers blow up at the bottom of the laptop, and the fan intakes are at the sides of the cooler- that way you can use the cooler on your lap. the targus awe11 is an example...

 

I built my own for my old HP Pavilion ze4281 in tech studies in yr11. No fans, just a wooden frame with slats in it for ventillation and a hinged panel either side for a mousepad. I've been using it with my new HP dv6519tx and it still works like a charm!

 

Maybe your laptop isn't any different from you, but my laptop doesn't need to eat, have emotions, or feel pain. The reason you get cool from a fan blowing on you is because of perspiration. Water evaporates, you get cooler as the heat goes with the water. Unfortunately, my laptop doesn't sweat, and thus I can't compare my laptop with myself.

Laptop fans are designed to move air around. It doesn't matter which direction the air flows, just as long as it's moving the hot air and replacing it with cold air.

Please think a little bit before you criticize "retarded engineers".

 

Yeah definitely just as my original statement some notebooks use the vents to blow air out other have it going in. If you try to go against the natural design of the notebook you can make cooling worse.

You want air FLOW not turbulence.

The best design would be intake on the bottom, exhaust at the top because hot air goes up.... this is how great desktop cooling works with a "blowhole" however notebooks dont have the same body and this is not much of an option.
