Hi, all. I have a Dell T3500 with the beefier HS, and X5672. The time is coming for me to give the computer a good cleaning, as I'm a smoker. Keeping in mind that I really don't have much money to play with, would this be good? https://www.newegg.com/Product/Product.aspx?Item=N82E16835103099 Again, the cheaper the better. But since the T3500 HS is passive, I guess anything active would be better.
