Why do you have an interest in a "better" fan? Are you having an issue such as noise, heat or both?

not that i know of, small fan , all small fans make a fair amount of noise when system is under load......

is it making a ton of noise all the time?

is the fan going bad?

( unibodys are usually pretty good about cooling compared to some of the non unibodys i have owned that get quite hot on the bottom)......

I do know of some high quality fans however they are larger 120mm fans for desktop systems, usually HTPC based systems to reduce ambient noise as much as possible. Nexus comes to mind. I haven't spent a lot of time checking out smaller fans since small fans usually turn at high RPM's = a fair mount of noise, so i could be wrong about after market smaller fans........

It will be difficult to find another fan that it will be better and suitable for the laptop. To find a better fan you should check to find fan at the same exact size, same voltage same amp but more RPM. That of course it will cost you battery life and honestly i don't think that you can find another fan suitable except from it's own.

If there is a heat problem you can replace the fan and change the thermal paste on the CPU and for a big amount of time your computer will run in lower temperatures.

If heat is a problem, I recommend installing the App Temperature Guage Pro (TG Pro). It isn't free, but it's fairly cheap.

Firstly, it shows you the temperature at your highest reading sensor AND current fan RPM in the top menu bar at all times.

Secondly, by clicking that display, you can get a readout of all your temperatures across the computer.

Lastly, and perhaps best, you get more intricate control over your fans. The default setting is System, meaning the OS is in full control. The next setting is Manual. This means you adjust a slider to control your fan speeds. Be careful with this one because regardless of how hot you get, that's where you'll stay. The last option, and the one I keep active, is Auto Boost. Within the app's preferences>fans widget, you can set up a series of custom rules. For instance: Exhaust to 100% when any sensor is above 80˚C. You may use this to ramp up your fan speeds at cooler temperatures than the OS normally would. In this mode, the system is more or less in control until your computer hits your rules, at which point your controls take over.

If you still find yourself running too hot, consider investing in a cooling pad. It's basically a device with fans inside it, that helps keep air moving under your computer. They run from $20 to $40 from what I've seen.
