This is perfect. I have a laptop that heats up so bad I cant use it. Definitely going to give this a shot.

I’ve done similar with some high powered blowers that I found and the output ports were roughly the same size as the vents on the sides.
The fan intakes are on the bottom, the exhaust ports are at the rear. The vents on the side allow for addition airflow, like additional force air cooling :)

I’ve been considering a home brew docking station with the blowers built into it. The plan was to create a vertical stand with the ports on the bottom. The laptop slides in closed. But I end up loosing a monitor port this was AFAIK.

I agree with twistedsymphony that this would be great recessed into a desk. My laptop is a medion that has the intake on the top right and, worryingly, no vents in or out on the underside. So this is not for me, as a portable option I like ‘the waldic’ watercooler with a copper radiator clipped on the back of the monitor.

piezo would be hard based on the form-factor of my laptop anyway.. the heat-sink doesn't sit on the GPU - it's over a few inches and uses a heat-pipe:

not sure how typical that is?

@1: think of it as a docking-station.

@7: drugs'r bad, mkuyyy?

@10: Believe me, 110CFM is a LOT of air to pump over heat sinks that are only 1x4cm in profile.

@14: that's *exactly* what it's made from ;)

@15: well it essentially does do that... it's basically pressurizing the intake port for the laptop's built-in fans. I've got several ideas on how to make it more elegant/efficient, but this was 40 minutes of work.. and like you said, it's hard to argue w/ the results. (I'm actually not temperature limited now.. I can run whatever clock I want without overheating - now it's just speed-path limited in the GPU die itself. 379mhz works, while 380mhz fails..)

omega piezo micro channel single phase liquid cooling...has anyone tried something like this for laptop cooling?

I like the project, but instead of a brute force approach where the airflow takes an arbitrary path, i’d like to see something that augments the airflow that’s already engineered into the laptop.
Based on your results that’s probably a moot point. :D

My modest Dell B130 doesn’t get hot enough to warrant that kind of cooling, but it’s still a good idea and pretty well executed as well.

Hmm, I should permanently attach something like that to my laptop…

It’s batteries no longer work, been off warranty for years, and been planning to do something crazy with it. (leds all over the place, maybe a smoker unit from a model train, cantenna on top the screen, big fans, and f I can find a small enough printer, I’ll tape it on :P)

yea I have a hp zd7000 also I sent it in cause of that and they replaced the fan and the hardrive and battery and now it runs cool and smooth. WAS FREE AND UNDER WARRANTY!

I used to set it up on hackysacks to keep it from overheating it self and sometimes it still would.

I’ve done various things like this in the past, simple and clean. Now if only he hooked up a vary high CFM lowe noise blower, he might really be able to push it.

I agree, laptops can get very hot. I own an alienware laptop with SLi and it gets extremly hot. I will take a shot at this one, I don’t see how it can give 50% increase in frames…but I’m willing to try it out.

this hack is certainly not bullshit. many students or professionals can only afford one computer. if you like to work hard and play hard, at the least this is an interesting solution.

The cpu?
And overclocking isn’t limited to desktops. From what I know laptops produce a lot of heat anyway, and processors run better at cooler temperatures. A cold processor will run smoother than a hot one, overclocked or not.

This hack is bullshit because if i want overclocked stuff i get a desktop and if i want a laptop i dont want such a silly bulky ugly thing. And a cool laptop doesn’t stay fresh longer either. a recent study showed, that harddisks dont die of heat. what else should die of heat? The display?
