I have not bought the cooler yet Boris. I'm thinking about the possibility of the three fans causing the LCD to flicker (remember the complaint with the LED reading light). But the specs indicate that the noise level is 18dBA. I'm not sure how to translate that into qualitative terms though. But one website gave these stats: 10db normal breathing, 20db mosquito and rustling leaves. The specs, however, do not include the power requirement.

Funny thing is, I have no need for a cooler for my laptop with its 12-cell battery giving it sufficient tilt on top of the low UK temps (and my freezing flat). But the eDGe temp from last time got me scared enough to contemplate buying a cooler. I'll monitor it in the following days and see if it was just an atypical occurrence.
