5 out of 5 eggsMach 9 speed!

Pros: They are Top Motor (Rexus's branded). It's a Dynatron fan, high quality. Put a pair of wings on your chassis, it'll fly away!

They push massive amounts of air at stated specs. A fan controller is a must here. Used molex of course.

Cons: Well, I had an idea what to expect and it exceeded my expectations-they move air! Not really a con. The con was in a this "special build" using an Intel D915PGN N.O.S. system board. The INTC 3.8Ghz Prescott I needed to cool must be the hottest CPU ever made. 115TDP. The problem was, that these fans had zero effect on cooling that CPU. Bizzare!

Previous to getting these turbines, used the XIGMA XFS-F1252's, stated specs. @ 1500RPM 45.2 CFM. The XGMA's are super quiet, lower RPM's, put them back in the chassis. Where the solution to the CPU problem was solved, was in INTC's BIOS. Where? Turn off your CPU fan control. Really? Temps dropped from 48C at idle to 39C even reaching 35C on the low end. For a Prescott that's a miracle. Check out the net on the P4 670 Prescott, a nightmare cooling it .

Case temps from 40C to 30C on average. INTC rule-of-thumb is maintaining chassis temps at 38C, regardless of the CPU type. Read every white paper of of INTC's site on chassis maximum temps.

This was an interestesting experiment. For others this might not apply in regards to using these fans, every system board is different, etc., They may workout perfectly, they move huge amounts of air.
However, a solution was found elsewhere.

Regardless, will keep the two Top Motors. Will need a fan control on them. I came back to Rexus Top-Motor as I have their 92mm mounted in a air-duct, Enlight chassis, cooling an E8400 Wolfdale. Temps 35C idle 42C at load. Chassis temps at 28C. And only 2-80mm, 1 intake 1 exhaust. Been running this sysytem for 4 years 24/7/365. The Rexus is top notch. No cons.

Can't hear the Rexus 92mm, the case is dead quiet.

Other Thoughts: Cooling solutions come out from left field...

4 out of 5 eggsSturdy and Powerful

Pros: The airflow is outstanding. I bought a new 280x and my PC was getting hot, especially with an OC 2500k. I bought two of these to replace a big and slow 200mm fan. And I can notice a HUGE difference, while gaming on high intensive games and idling (watching a show, doing work ect.)

-It spins, FAST
-Sturdy
-No vibration noise
-No LED
-Noise can't be heard if playing a game
-Inexpensive
-"easy" install, except no threads!

Cons: -Somewhat loud (not a big deal while playing a game or if you have a fan controller while idling)

-No LED

-Fan controller might be preferred (I bought one fore these)

-Not pre-threaded, can be a hassle

Other Thoughts: If the fans weren't exposed, this will keep a person cool in these hot Florida winters. Don't stick your fingers in it!
Might build a hovercraft with these!
If the cables were somehow black, I would like that.

I bought two of them, I look forward to buying more in the future! 8/10

5 out of 5 eggsIncredible

Pros: Great airflow. Running 4 fans in my HAF912 case. Case came with low cfm fans. Swapped a stock intake for one of these. Night and day difference in performance.
Using another for exhaust.
HUGE difference in airflow. No noise. None. I barely HEAR the air moving,but you can FEEL the air moving 8-10 inches away. Well built fans. Buying 4 more (2 for CPU cooler,front intake, side panel) Best fans i've ever owned.

Cons: None.

5 out of 5 eggsGreat Fan

Pros: * Keeps CPU temp down
I used this fan as a replacement for my stock water cooler fan. It spins 2700 RPM max. It keeps my CPU cooler than the stock fan.

Cons: * Loud
It definitely is loud at 2700RPM. Make sure you get a fan controller or connected it to your case fan controller.

2 out of 5 eggspoor quality

Pros: It spins. Speed is as advertised.

Cons: Fan is unbalanced and thus produces a great deal of vibration. I returned it.

4 out of 5 eggsFast, but not quiet

Pros: Brought my temps down significantly which enabled me to OC more, especially at idle.
After testing it brought temps down from 76 to 66C at 4.4ghz on a AMD FX-8150, that was using prim95. During video rendering it doesn't climb above 59c.

Cons: Loud. My previous fan was an Antec 120mm which was virtually silent. This fan has such a loud whine to it, my right ear starts ringing after a long time under load. Possibly a bad fan, gonna try to RMA.

Other Thoughts: Despite the noise. I have an Arctic freezer A30 heatsink with a 120mm fan attached to it. The stock fan was not powerful enough to let me OC at all. The cheap Antec 120mm I bought from Best Buy allowed me to get to 4.2 somewhat comfortably. This fan allows me to get to 4.4ghz comfortably.

5 out of 5 eggsLike a mini turbine!

Pros: Moves a TON of air, and helped lower CPU temps when i added to my HS. It has 3 pin and a 4 pin molex if you run out of fan headers and dont have a fan controller.

Cons: Makes lots of noise moving that air. Seriously, if you are OCing and need the airflow this is great, but in a normal everyday system, I would pass. Its just too noticably loud.

Other Thoughts: Ugly molex hardly needed these days, but props for supporting the legacy folks that still want good cooling.
I gave it 5 stars because i wanted to max the cooling potential of my Air cooled HS and I feel like it has done that, but if you care about the noise, I'd get a lower CFM fan.

5 out of 5 eggsH00TERS

Pros: This is the 2nd Rexus 120mm fan i got of this model. It is working perfectly. I bought this same fan 8/24/2008 8:54:48 AM and left a review that is just as good. The fan works great and allows you to control speeds. Its not that loud since i can tune as needed.

Cons: n/a

Other Thoughts: Buy a fan controller and you can still get great CFM with lower speeds if you want to be quiet. The fan is not that loud even on high.
