I ordered the CNPS7000-Cu for my new upcoming computer. I was torn between that, and the Thermalright 900U. I liked the Zalman because it already had a fan, and it will fit the upcoming AMD64 and new Pentiums. The weight, while a slight concern, shouldn't be a big problem. Let's face it, they wouldn't sell the thing if it was breaking CPU's. Now, you probably should move your computer around GENTLY with it on there.. but that should go without saying no matter what's in your computer.
For $19, without the need to get a new fan. Decision over! Awesome price. Cheapeast the Thermalright can be had for is $37, and then you need to buy a fan.
