Summary: I can't say if it was just the one I received or if they all will have the problems I had with mine. I bought it to help cool an old graphics card i have that came with a passive cooler, one fan is working alright and steady but the other died within a few weeks.
Pros: Cheep, Worked well at first One fan seems to do the job well enough
Cons: One of the fans died after a few weeks, had to cut the wires to prevent it from getting too hot (after the fan died the motor was getting extremely hot and started to melt the plastic
Summary: A good idea but fully lacking in R&D A major flop in money saving engineering.
Pros: The fans turn; and oh yeah, they are kinda UV reactive.
Cons: Evercool usually makes quite good cooling products; THIS IS NOT ONE OF THEM! The plastic construction is flimsy as are the fans. The everlubricate bearings are NOT good quality, but are rather just bushings. One of the fans has a dry and out of round bushing that pretty much always chatters, even...
Summary: Dont buy this. It appears, at best, you rent its usefullness for a few months....Then try to return it or toss it in the garbage
Pros: It moved plenty of air over my GPU
Cons: It became unstable after a few months. Unbalanced and rattling. I tried adding more grease and cleaning, in an attempt to rebalance...nothing helped it. I believe the center shaft becomes loose, resulting in wable.
