Sealing of a case

[mike1968]

This will hopefully be my last question for a while. I recently bought an intake fan for the front of my case http://www.newegg.com/Product/Product.asp?Item=N82E16835185020 It leaves small gaps on each side of it. What can I do to seal the gaps off. I was thinking about maybe getting some fan vibration dampners but I dont know if they would stretch all the way around it since the case that holds the fan is much larger then 120mm.
I have another question and rather then start a new thread I will ask it here. I went to home depot today and was checking out surge protectors and saw that some say for Home theaters and others say for PCs. Is there a difference?

Electrical tape? It's hard to answer because I don't know what these gaps look like.

Frankly, I wouldn't worry about it. Sealing those gaps probably aren't going to make even a degree's worth of difference.
