As to if they have the 120mm fan in red, yes, they do. It comes in a few colors I believe. Different model number, though, just looked it up. Here's one from
Fry's Electronics…
red fan cool
I think red is better because it doesn't hurt your eyes.
There are also green and purple fans and even RGB fans
You can have fans of any color, you can replace the LEDs yourself !
Just look at all
these fans
Those fans have many small blades vs the typical fan which has fewer but larger blades. What's the pros and cons?
You talk about the more expensive fans, but how does the really cheap ones on ebay compare? Like
this one? It is a popular cheap color fan but only 38.4 CFM. Have you ever got any of these? They look cheap. Also there is
this one which is about $5 per fan and push 66.2 CFM. How do they compare to the average PC fan in some Dell or HP pc?
Oh I just found out, it seems that fans in-stores like Best buy and Walmart and Fry's are cheaper than buying online! You bought a fan for $4 and I think you said it was good.
