Query: Better than expected

I bought this blower to help cool a passive (no-fan) graphics card. I wasn't expecting much based on other reviews in here but it definitely does the job. My GPU temp dropped a solid 20C+ under load. It is not quiet (it's a blower not a fan) but it is background white noise that blends with the rest.So keep in mind YMMV with this blower. If your cards have fans and your case has multiple fans don't expect much of an improvement. But if you only have a PSU fan cooling your case this will give you that airflow boost you need.I hope this blower is durable. But if I have to buy a new one after a year I wouldn't complain.Update: After about a month of use I've decided to run the blower at 7v. It is now much quieter, nearly silent, and still cools just as well as before.
