Summary: Spectra pro 200mm moves more air, but mounts off-center on the haf xb lid..Coolmaster megaflow is however a perfect fit and looks nice with sleeved 3pin fan extension. NZXT 600mm 3 pin extension. I don't know why, but both of these 200mm fans turn faster after 3 months of use..They get better..Intels free Intel [R] active monitor will track fan speeds and zone temps with alarms should one stop or temps rise above thersholds..
Summary: I purchased two of these as one of my Corsair 650D case fans was going bad. Luckily the one at the top of the case was the one that was dying, so it was easily replaceable. the other fan is mounted between the front of the case and the drive cages. This fan is about twice as thick as the Corsair branded fans, and as such it doesn't fit. My advice is to visually inspect where the fan is intended to go before pulling the trigger.
Summary: I have a CM HAF series case and I have this fan mounted to the top. Noticed a 3-4 degree difference with my current setup: 2 - 120 mm front intake fans; 1 - 140 mm side exhaust fan; 1 - 120 mm rear exhaust fan; 1 - 200 mm top exhaust fan; 1 - CM Hyper 212+ CPU heatsink/fan; 4 HDDs, 1 SSD; i5 2500K OC'ed 4.5 GHz; AMD Radeon 7870 graphics card Fan speed: close enough to the 700RPM advertised Note: 1 star taken away because of the rather poor design of the placement of the...
Summary: I bought these because they were recommended for use in the Coolermaster HAF XM case. They are descent fans, bur not super air movers. They do glow red as advertised and they do an OK job, but there are other fans out there that will move much more air if that is your need. I have been using these for several weeks now and they work fine. If you are an OCer and need to push tons of air, then I would suggest that you shop around for another product.
Summary: Bought three of these for my Coolermaster Haf X case (two upper and one side). Originally, I only bought one to add in the optional top fan slot. After installing it (and with the Haf X case, the optional fan slot does have issues with fitment due to the USB 3.0 cables, but doesn't impede any fitment after a few minor tweeks (mainly cutting a zip-tie, and rerouting the two USB cables)), I ordred two more fans for the case.
Summary: This fan moves more air than most others this size but I was still expecting more. On the plus size it's whisper quiet. I just wish the bright LEDs could be turned off without snipping their leads which is somewhat more permanent than a switch. Still, if you need better airflow this is a good, cheap way to go. One note: Mine didn't come with mounting screws so I had to scrounge for some. If you don't have them lying around I'm sure Amazon has a compatible set for sale.
