| [Cooling] Corsair H100 and Cooler Master HAF 932 - RC-932-KKN5- The HAF 932 has a 230mm fan mounted on the top preinstalled but you can mount up to 3 120mm fans in there instead. The Corsair H100 has 2 120mm fans on one side of the radiator. My question is, when I mount the H100 radiator to the top of the case, would it be better to install 2 120mm fans in place of the 230mm fan? Will I have any sort of air flow problems? I'm looking to OC my i5 2500k to around 5ghz.

As you can see from the picture of the HAF, there is a 230mm fan but it has mounts for 3 120mm fans. As you can see from the H100 photo, it has a large radiator with 2 120mm fan mounts. The other side of the radiator would be mounted to the 120mm holes on the bottom of the top of the case.
I will have the top fans push air into the radiator and the fans on the otherside of the radiator pull air. There will be a 230mm exhaust fan on the back of the case just beneath the radiator to catch the hot air from the radiator before it reaches my video cards. Will the fact that there is a 230mm on top of the radiator affect the cooling? Would I be better off getting 2 120mm fans so it lines up more evenly with the radiator or will a 230mm fan do just fine? |

| Re: [Cooling] Corsair H100 and Cooler Master HAF 932 - RC-932-K You should get 4 of the same fans to mount to the h100, if you mount different types you can burn em out, hurt your airflow, etc.
Also the 230's are just gona push around the rad, they need to be butted up to the rad to get any real pressure.
Air flow you can always play with. I would try 3 120s up top... intake (if you want... I mean being real you likely won't see bad temps if you went with exhaust over the h100 few c tops) front intake, back and side exhaust. Should give good airflow.
Myself, I'd do top exhaust with the h100, front intake, side intake, and rear intake. |

1 edit | I can't replace the radiator fans, from what I've read no other fans will properly fit the holes. That being said, how important is it that I find 2 fans that have the same RPM? The fans that come w/the H100 are 1500/2000/2500 rpm. Should I just get 2 2000rpm fans? I can have those push air into the radiator, and have the bottom 2 fans of the radiator pull air out. The exhaust fan should immediately kick the hot air out.
If I use the top 120mm fans for exhaust (pull) and the bottom radiator fans to push air through the radiator and out the top exhaust fans, won't that be pushing warm air from the rest of the PC into the radiator? Wouldn't it be better to pull cool air from the top of the case into the radiator and then use the back exhaust to dispose of it? I'm totally new to overclocking/cooling so I could be completely wrong. |

kudos:3 | I doubt that the 120mm fans are proprietary. I know on my H70 that I was able to easily replace the stock fans with some thermaltake ones.
But if they really are then you need to try to match CFM and Static pressure so that they'll be roughly even. |

OKay where did you see that other fan's won't fit? I see tons of threads asking what fans to use with the h100. Even on the corsair forums.
I already posted what can happen if you use different fans... you can hurt airflow, burn up the fans. If you do you would need try to make static pressure and CFM... as close as you could to not having one fan pushing the other. Think hair dryer (on cool) behind case fan... it will spin that case fan WAY faster than it should. However, you also do not want the blow dryer in front of the case fan... as now you are restricting it (gona overheat).
As far as pushing hot air though the rad, yep you will... but...
What hot air? You will be turning over air so fast, really what do you think you will see? 1C higher temps?
You want positive pressure in the case (more intake CFM than exhaust) + pressure means the air will be trying to get out of the vid card, the rad, etc. Because you have pressure pushing on it rather than intake on the rad trying to make pressure.
I mean as I said... play with it. You might find better temps with the rad doing exhaust, you might get 5C better with the rad being intake.
Only thing to think of... it's cool you got the CPU cooled nice with intake... but you are blowing all the hot air *into* your case, heating up your mobo, vid card, hdd, etc etc. Imho I'd take 1-2C on the CPU over how many C on the hdd, vid card, mobo... |

| You are right regarding the fans fitting. I read some posts complaining about how the holes weren't lining up properly with the radiator but I think they were talking about the case fan holes. I'm pretty sure my case will work with the H100 mounted to the top judging from other posts. I'll play with the air flow configurations. I have a pretty big exhaust fan on the back of the case right beneath where the H100 radiator will be. Also, I don't intend on OCing my GPUs just because I doubt i will need to. I'm really just concerned with maximizing my CPU speed because I don't want it to bottleneck my GPUs. |
