Zalman has two big fans (max. 1500 RPM) with many holes for better air circulation. This holes exactly fits proportions of EEE. Zalman is connected over USB, has off button and speed control - you can set fans speed from 1200 RPM (quite silent) to 1500 RPM (loud but better than my Acer:).
So let's go on!
Internal fan in EEE started at 55 degrees. With Zalman at 1200 RPM one minute later - internal fan was already off - temperature of 50 degrees. Nice, I could turn Zalman off. But I wanted more and more and more! So - Zalman at top speed of 1500 RPM and nothing!!! EEE stayed at 50 degrees!!! Bottom surface is now really cold, my hands are cold from cold air blowing from Zalman but actual temperature is 46 degrees (with EEE running at 112.5 MHz!!!). And even keyboard is still HOT! Wow ;)
So the result - it's not rumor that EEE has bad design of cooling system - it's right :( We have to wait for fanless EEE with (I hope) better cooling...
PS: I'm going to test EEE cooling capability deeper soon :)
