Well I was thinking of cutting the two wires and soldering them to new fan as the only solution... You're right, warranty expired so no damage there. I don't have a lot of experience, but I watched a couple of youtube tutorials and I think I'm up for the job.
I was told that my current fan specs are: +12Vdc, 0.45A,. 87.85 CFM. 2400rpm, 38.3 dBA
So I'm looking for something that will do the same job with less noise.
