Choose a fan with a high static pressure for the HDD in-take fan (in general for anywhere that is obstructed, either CPU heatsink, hard drive cage fan, or fan where there is a filter and door in front of it). A noctua NF-P12 is probably a good choice. Calculate the CFM of all your intake fans by adding together the CFM at the appropriate RPM. Subtract the CFM of your exhaust fans. Ideally you want a slightly positive result in order to create positive case pressure so that dust does not get sucked in but is instead prevented from entering by the higher than atmospheric pressure in the case.

An HAF 912 is kinda cheap... you can even get it used.

No down volting will not slow the clocks,
I start when undervolting @ 1.25 and then boot > test stability if it flakes out then I up the Volts one increment > then test stability again,

But then I use power management so if the pc is idle the cpu ratio drops and so does the voltage,

It's a mid tower though; I'd prefer to get a full tower as I am going to have large GPU's in the system.

Where can I find windows power management? Tried searching for it in the run menu; can't find it.

Control Panel > power options,
Balanced (recommended)
Power Saver
High Performance

you will have an advanced tab click that and you can change processor power management,

I set mine to
CPU min = 5%
CPU Max =100%

I did have it on high performance if that made a difference.
post #28 of 31
high Performance will not throttle the CPU down when in idle,

Just change the CPU section like I said min=5% max=100% and you will run cooler,

I don't see that CPU section in the power management, where is it?

Down volting at stock speed *can* mean reducing the speed, but the idea is to cut the core voltage down a little at a time, checking stability with the same tools as overclocking.
The plan is to find the lowest voltage it will run stably at stock speeds. This will cut the heat output.
