Adjusting Fan Speed on Laptop Cooler

So I have the CoolerMaster U3 Laptop Cooler Newegg.com - COOLER MASTER Notebook Cooler Model NotePal U3 R9-NBC-8PCK-GP
and noticed that the fans could definitely be faster, which in theory would cool my temps down even more.
For those that didn't know, the Fan Speed on the U3 is 950-1800 RPM.
I happened to notice that there are fans capable of way faster speeds. Some near 7-8k RPM..

So the questions I have are:
-Can I adjust my fan speed even higher? (Yes I know how to adjust it with the clip-on speed controller)
-Are there laptop coolers on the market that come equipped with very fast fans?
-Has anyone modded there cooler with quicker fans?

 

One thing I would do is take a voltmeter/ammeter (Fluke or meterman or whatever) and figure out how the fan is controlled (likely voltage controlled).

Then I would find a power source I can plug into the fan that has a higher voltage (if it is indeed voltage) than the max setting and try it out. Of course you might burn out your fan. So I would recommend you get a power source with a variable voltage and a current rating obviously higher and start off with small increments. If you smell something you've probably gone too far.

I doubt you'll be able to get it to spin faster if you're powering it via USB plugged the M14x.

So if you're confident enough to splice some wires and start experimenting with higher voltages, and don't mind risking the fans, have fun!

Or just buy better fans if you're lazy and have the $$$.

Also keep in mind that higher RPM doesn't always relate to higher amount of pushed air (CFM).

 

Well wouldn't faster fans push more air flow out? I mean that makes sense to me..

 

No.
It depends on many factors like the shape of the blades, the size of the motor etc.

 

Thanks for clarifying. But wouldn't a bigger motor mean more speed resulting in higher RPM's?

 

Bigger motor would also mean smaller blades and less amount of air moved
