I have an HP envy Phoenix h9-1387. I'm looking to replace the stock 92mm fan on the radiator with a 120mm. It seems to have a spacer on it. I want to replace it to try and remedy the temperatures I am seeing inside the case. (50-63ish under load.)
I don' know I it will fit though, and I do not want to waste money on something that wont work. http://imgur.com/y0XTX4c
Here is a picture of it.
