COOLER MASTER R4-L8S-182B-GP 80mm 4 BLUE LED LED Blue LED Standard Fan 80 ST3

Pros: This is the low RPM fan for quiet cooling--especially good where the fan will "suck on a grille" like the Intake fan at the front of the PC. Excellent for the HTPC and other really quiet computers. Also great for adding a bit of style.

Cons: Not for CPU cooling. Not for use with a fan controller or motherboard "auto fan" function (because these are already at the silent rate of speed).

Overall Review: An excellent product. There is no flashing--that's clear blades plus lights making pretty blue reflections. Why are you guys staring at the insides of your PCs anyway? Can cool an energy star compliant CPU that's equipped with "the big chunky" heatsink. Otherwise, the same manufacturer makes a "rifle" bearing CPU fan (only in plain black) better for that job. However, these blue fans can be applied within a hard drive bay, overtop of the video card, and they can be used on a nice blue "60-80 funnel" to replace noisy 60mm fans in HTPCs. Low power consumption goes well with "green power" builds (like Fortron Source Green and Seasonic based projects). Very useful in Micro ATX and ITX builds where the computer is smaller and more personal (and very quiet). They do not require a fan controller, and that is more cost-effective--a fantastic timesaver!

Pros: Good price...

Cons: Although, they don't work. Right out of the box niether of them worked. I tried them on two rigs. Went to Cooler Master's website, they had horrible service there. When I bought them, newegg had a $5 mail in rebate deal, that I never recieved.

Overall Review: The rest of these reviews seem to suggest it's a good fan. Maybe I just got an unlucky pair. I could send them back but $5.00 is not even worth the hastle.
