EXTREMELY LOUD!!! I MEAN EXTREMELY!!! Plus it is large, and very hard to install.
Ok well after taking about 45 minutes to install this sucker, I hooked everything up and turned on my computer. I was worried that I had accidentaly turned on the JET ENGINE that i keep under my desk. This bad boy is LOUD!!!!! I can hear this thing all the way upstairs. But it does keep my processor fairly cool, but gives me a headache after about 30 minutes. My suggestion: buy something else...or if you like orbs, get this and a good pair of earplugs
