750D case fans and H100i fans


snapper69

Recommended Posts

I am the proud owner of an Obsidian 750D and I have recently bought an H100i. I have a couple of questions:

 

Which are the best fans for the front/rear of the case, will Noctua NF-A15 PWM fans fit?

 

What are the best fans for the H100i? I was going to use 4 Akasa Apache Black 120 fans in push/pull, but I'm not sure that there's enough room. Are there better fans that would do the job in a pull configuration? I want to overclock my 3570K to 4.4, keep the temps reasonable and keep the system quiet. Not much to ask:)

Fans with High Static Pressure would be recommended for the front panel, being the front panel severely restricts airflow when its on. Static Pressure fans (or fans with High Static Pressure) are recommended for radiators as well.

 

The stock fans are going to be the best bet on the h100i, but they can get really loud at higher rpms. Push/Pull isn't really worth it (pushing air through a radiator cools it, not drawing hot air off), makes about 1 degree difference. The stock fans on the h100i are incredible, and I haven't seen a single aftermarket fan that will out preform them yet.

 

I am curious if Air Series SP120 PWM Quiet Edition in a Push/Pull would preform equal to stock h100i fans though. I'm pretty sure the SP120 series share the same fan blade design as the stock h100i fans but run at lower rpms.

 

Depending upon your motherboard there should be plenty space to do an internal push/pull on a the h100i, but it is going to be a tight fit. Just stick to 25mm thick fans.

If you dont mind spending a few bucks (upto $30 per fan, but you would not need to have more than 2) there are some killer delta 120x38 that are actually rather quiet when not spinning very fast. (low speed setting on my h100 pump controller)

 

I have some on my h100 and my q6600 running 99.9% stable (only has issues with IBT once in a while when it gets above 75*c, I should take it apart and lap the cpu HS and the pump cold plate)

I finally decide to get 2 Noctua NF-F12PWM fans for the H100i and 3 Akasa Apache Black 140mm fans for the case. I'm considering using all 3 of the Akasa fans (2 at the front and 1 at the back of the case) to suck air in and the 2 Noctua fans on top of the H100i to pull air out.

be careful using delta fans on the h100 as most pull too many amps...

I've used cougar vortex, sp120 QE's, and scythe gentle typhoons in push / pull (both 7 volts and 12 volts) on a build with an h100i. My favorite by far was the sp120's for noise to performance plus great aesthetics. They all performed within 3 degrees of each other. I'm sure the case would also be with the noctua's. high quality fans are high quality fans.
