I am not certain they were UF. They look very much like the blue and white UF pic you posted, but the body was more grey than white. Slightly flexible rubber. Again really liked them, till they started having issues. Maybe I got a bad batch. The TF are great though, and for the price, it's hard to go wrong.

Not sure which one is the TF line. Mine is the same as the red one though I have red white and blue (not a patriotic thing, just a play with colors thing). Personally I have had a much better experience with these than the old Deep Cool. I liked the old ones, but I had two get noisy bearings, and die within a year. I started running the gamerstorm's over a year ago, and they are as quite as the day I bought them and move allot of air. My all time favorite fanz are the original noiseblockers, but the gamerstorms are less than $10 a piece and move just as much air. Not as quite as NB's though. NB's have no LED's btw, and are damn sexy imho (original purple and black versions).

Gamestormers are deep cool's newer line or maybe new name, and though they have LED's they are in the corners with difusers. For the price point and serious airflow the gamestormers are now my goto fans. Though my case is a hodge podge of fans. Function before fashion. The second pic is the view from my seat, and those are game stormers lights. Not so bad.

@mee vitaliy is making fun of the led lights.
