Total : £830.90 (includes shipping : £12.50).



I wanted to ask for opinions on cooling. Specifically fan configuration and selection. From the outset I suspect I want to scrap all fans that come as stock for custom, likely from the Noctua range. I have heard unhappy noises regarding Corsair stock fans.

Current Assumptions/Planning
Regarding the H100i, the research I have already carried out seems to suggest that push pull configuration is somewhat inefficient/redundant these days. Instead it should be configured thus: Top of case => fans => rad = a pull configuration with the top acting as exhaust.

Among the reasons for this is ease of cleaning/dust build-up control and optimal pressure versus additional noise/power consumption from the extra layer of fans. Saying that, if there is any real world experience suggesting otherwise I will switch to a push pull configuration. Assuming the 750d can handle that of course.

The Noctua NF-F12 is what I was considering for placement on the H100i rad. For all other 140mm points in the case I was considering NF-A14s and NF-P12s for all 120mm points thus:

x4 NF-F12 (H100i if going push pull)
x3 NF-A14 (x2 Case front, x1 case rear)
x2 NF-P12 (Case bottom)

All will be PWM; the H100i will control it's set of 2 or 4 fans while all others will use the motherboard headers and be under software control. Presumably I should make use of Asus's touted PWM over splitter for fan groupings such as the front and bottom - or possibly let the software group them under a common profile (if that's possible).

My Questions
First of all, do my assumptions/planning seem reasonable?

Am I matching these fan models correctly as the size scales up? I based this off of this chart: http://www.noctua.at/main.php?show=which_fan_is_right_for_me&lng=en

If I were to switch my case choice to a 650D then would it still be possible to mount the H100i in push pull?

What's the real world working opinion of anti vibration rubber fan mounts? I am correctly or incorrectly considering using them for case mounted fans.


I eagerly welcome any suggestions, opinions or criticism.

For less or similar money you can quieter and better cooling with a good air cooler.
H100i is 6 times as loud and still 2-4c hotter than NH-D15 and Cryorig R1 Ultimate.

Lower the H100i's fan speed to 39dBA (still 1-6dBA louder) and now 7-9c hotter than air coolers
