Pros: Bright and move air well

Cons: none

Overall Review: Well worth the price

Pros: they are pretty lit up with blades of sparkles They are a claimed 50cfm and I can NOT hear they are quiet set to 100% with a fan controller. I have enough out of the tree to exhaust my case in summer and I pull I would imagine 150w actual heat with 24SMT processors and a RXVega64,I read 90w in CPUID HWMON alone for the Ryzen.

Cons: not freebies

Overall Review: A-OK space cadet ! Figurient the cost....they are not PWM need old fashion fan controll....I HAD THAT !!!!

Pros: Quiet, great looking, and inexpensive....Trifecta.

Cons: Shipping time

Overall Review: Excellent value ~ just order them 2 weeks before you need them.

Pros: Duel hook up to power, quiet, and bright. Hooked two up to my motherboard using the 3 pins and one to the power supply with molex, so easy.

Cons: None at this price point.

Overall Review: They are bright, if you want subtle buy a controller to go with them. If you have a filter in front of them it will mute the light to a subtle green. I did not buy them for subtle tones so they are fine for my use.

Pros: bright leds. move a ton of air. extremely quiet.

Cons: none

Overall Review: im currently running 13 of these fans. they are quieter than my old fans of which i only had 5 running.

Pros: 15 led. nice design

Cons: useless fan to have in a case if you need it to actually push/pull air. I have stock pre-installed fans that were more powerfull than these and thats sad lol

Overall Review: over all its a cool "lookin" fan just not that great in air flow. i guess its a ok fan for the 20 buck price
