I did however have to spent a solid 20minutes screwing on the fan. The holes did not have the screw marks, you had to use your screw and etch in the pattern in order to start screwing. I first screwed in the hole and after it had been etched, I removed the screw and then proceeded to mount it onto the tower.
1 other thing to note was that the 4 pin connects weren't aligned correctly. In fact they were a little crocked so I had to shift them in order to connect it.
By the end I was able to get it running and for the price I am very happy with what I got.

Only quirk is on and of for about 8 months of owning 2 of these for 4 years the one's bearing seemed to get loose I guess? It would rattle during startup then sort itself out. Hasn't happened since I rebuilt the PC in May this year though.
As for cons, mounting them was a pain. The holes don't come pre-grooved. So how do the fans mount then? Simple; you line the fan up with the fan vent, line up your screw, and twist it into the plastic hole carving it out. Not sure if all fans are like this, but I really needed to torque the screwdriver for 4/8 screws (two problem children on each fan).
I would have happily awarded this five stars except that when I went back to buy another set, they had removed shipping to my country. Why?
EDIT: Originally my only problem was that shipping to my country was removed. Happily they brought it back and I was able to order another pair for a new rig I'm building. This time, however, the cables were loosely seated on one of the fans: a couple were raised enough that the blades were hitting them. I don't generally mind noise levels, but two light slaps a couple of thousand times per minute is pretty annoying and potentially damaging. I used some duct tape to strap them in, but I shouldn't have had to do that. It also kind of threw off the color scheme, but that's mainly my fault for using duct tape instead of electrical tape.
It's also a good-looking fan. The red LEDs match relatively well with the CoolerMaster Megaflow 200mm fan I also use for exhaust.
Overall, I'm pretty happy with this fan. Not as quiet as advertised, but still a tremendous value for $8. You can generally adjust the fan speed in the BIOS, so you can make it as loud or as quiet as you want. The air flow trade off doesn't seem to be as steep as it was with the Tricool, either.
EDIT 9/24/2015: I'm still actively using the two of these fans I picked up when my original review was written, and they're still excellent fans. In fact, I've since decided to replace all the Corsair "Quiet Edition" (read: "Low RPM Edition") fans that came with my case with these, so that I've got the flexibility to move a lot of air when I want to. I use an NZXT fan controller anyway, so I can tone them down when I'm not stress testing. If you're thinking about spending more money on some "premium" fans, don't bother. These are great, and while they're noisy at full blast, you'll rarely need them to spin up that high because their air flow is so good.
My other complaint may not be entirely valid. The old fan was a 3 pin as well and noticeably sped up and slowed down with some control from the motherboard, presumably based on case temperature. This one is full speed all the time. Perhaps there was some specific feature I should have looked for in a fan indicating that it accepts this control. Don't know. But this isn't it.

- VERY powerful. more powerful than much more expensive fans I had.
- It will be noisy in certain conditions (depending on your case construction).
- The LED is rather dim. I'll let you decide if it's a pro or a con...To each their own.
- Cord length is not too short, but not too long that it'll require you to start cable-managing it. About 1ft long.
Installation is just as easy as every other fan I had.
So for 10$ (was on sale here), it's a real bargain!
