Rosewill 120mm Ultra Quiet Case Fan 4-Pack - Long Life Sleeve Bearing Computer Cooling Fan (ROCF-13001) for PC, Gaming Rig & Home Office Desktop - Perfect for Enhanced Airflow & Silent Operation

I have a system that I have a h60 water cooler on set up as the manufacture suggests so as to cool my i7-4790 down. (I don't overclock but still want my system to run cool.) To help this out I had added a side case fan that was pulling air out of the case. Unfortunately I only had a 90mm fan to use and it was very loud. I decided to get this 4 pack set and replace the smaller fan with a 120mm one so as to quieten things down and move a bit more air. I figured this set would give me a few spare fans if I needed them. I got them in and opened up the package and the first thing I noticed was the multi-style power plug that they came with. So if you need to plug them into the MB then you have a plug that will work and if you need to take the power off an older style HD power cable then you can. I also noted that each fan came with four mounting screws to use for attaching these to the frame. Again a very good touch here. So I pulled up my main system and opened her up. After taking out the old fan and doing a bit of drilling to get the new screw holes right, I mounted one on the side of my case cover where the old fan had been. I needed to provide a fan cover screen as the H60 water cooler tube were just a bit to close to the side of the case and that made sure they wouldn't get into the fan blades when replacing the cover. After getting the done and doing a bit of dusting out while I was act it, I hooked the fan up and put the case cover back on. I then cranked her back up, and at first, thought the new fan wasn't running as I couldn't hear anything. I placed my hand over the vent and could feel hot air venting from the case. I then opened up an app I use for checking case and CPU temps to see what they looked like. I noted a 2 to 3c lower temp on the MB sensor so moving a bit more air seems to have helped some with the added benefit that the system ran quieter. Not bad for the small cost and time it took. Not a bad fan at all.
