Question: Do anyone know if this will fit in a Cool Master HAF XB Evo?
Document: I like this fan. There aren't a whole lot of 200mm fans out there, so your choices are limited. I got this fan simply because I know it would fit my Cooler Master HAF XB case. It turned out to be quieter than I expected and moves a good amount of air (something you'd be looking for in a 200mm fan). I haven't had any issues with whining noises, or clicking noises and I've had it running at 100% since I got it several months ago.
I don't know much about PC hardware, but I'm a dummy so I tried building my own rig anyways.I spent months trying to figure out why my computer was BSOD'ing, but eventually figured out that it was temperature related.Long story short, this fan fit perfectly on my Cooler Master HAF RC-922M case and now my temps (under stress) are 10c or more lower than they were before.Perfect. No more crashes.
Hello all you computer junkies! I am reviewing the Cooler Master MegaFlow 200MM fan. I bought this for my computer knowing that I was getting great Cooler Master quality. This fan had to cool a GPU, Motherboard, and a CPU ( Somewhat). This pulled me through the massive problem that was heat. When I installed this fan.. My temps dropped almost 10% I was super impressed. I would recommend this to anyone who has the room for this. My PC ran amazingly well with this.
I bought this to mount in the top of my Cooler Master HAF XB case, and it works great, pushes a lot of air and is surprisingly quiet for the size.
Likes:  Matches my Cooler Master HAF case and the red lights in it.Bright but not too brightQuiet, moves a ton of airCons: Feels a little flimsy.I would recommend this fan to anyone that needs a large, red led fan.
Good to extract heat from the case, however it gets a bit louder when heat goes higher than 50C.Current gaming rig:Intel Core i5-4670KASUS Z87-CCorsair Builder Series CX 600 WattHyperX 8GB Kit (2x4GB) 1600MHz DDR3 PC3-12800EVGA GeForce GTX 770 SC 2GB GDDR5Crucial M500 120GBCooler Master HAF XB EVO (HAF XB Rev. 2)
Received the fan last night and gave it a try in my Coolermaster HAF-XB..  quite the letdown..
Installed this fan on a "Cooler Master HAF" case side-door. It is whisper-quiet and is very efficient. Red LED lights look cool too.
Went in the side of my Cooler Master HAF-X 942 and looks great, cant really hear it and moves a nice amount of air to keep my GPU's nice and cool.
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..
Answer: I have the case and the fan. They work well together. The only place to mount the fan is on the top panel.
