Cons: I've tried to use these several times and unless you have some fan controllers (I happen to have a lot of them so no biggie) they are more noisy than any other fans I've used. Can't recommend these if you want a quite machine.
Pros: bright enough cheap it does the job led lights are cool :)
Cons: screw holes are a little bit tight you have to screw them one by one to get the fitting right. i dont know if other led case fans are like that but this doesnt get an egg deduction not a biggie to me
Summary: The white leds go well with the blue ones that are already in my case. Compared to the fan that is on full blast, the fan below it is slightly less bright, because it is on setting 3/10. Kinda dorky, but not very noticeable. I got them on sale, woo!
Pros: They're so pretty. Lots of blades for some serious CFM's. Three great fans for my aging Antec 900, two of the original fans were rattling like crazy and I had one empty fan slot, so why not.
Cons: These are kind of loud on full, couldn't make the cord for one of them stretch all the way to the last socket on the motherboard, so I used the 3/4 pin adapter thingy and now its on full blast with no way to turn it down, this is the only reason I took an egg off. The cord without the adapter is only about 12" long. The 3/4 pin adapter is basically a 4 pin Molex for power with black and yellow going to 3 pin, so I can't adjust the fan's power when using this adapter.
