CM 212 Evo in Push/Pull with large RAM

[joaompp]

Will the Cooler Master Hyper 212 Evo fit as Push/Pull on my Asus P8Z77-V Deluxe motherboard using 2 Cougar's CF-V12HB? The RAM I'll be using is the Corsair Vengeance 4x4GB DDR3 1600 inside of a Cooler Master CM Storm Series Trooper.

Ivy Bridge produces so much heat so I want to make sure I keep it cool with good air flow.

i have my doubts that those heat spreaders on the RAM will fit under one of those fans in the first dimm slot.

btw, IB gets hot depending on what voltage you use to overclock.

To answer your question, I think it will be OK of you orient the fans parallel to the ram.
If necessary, the fan can be slipped up a bit to clear the heat spreaders.

But, why not just get a 2 x 8 gb kit of low profile ram instead?

1.5v ram really does not need heat spreaders, and ram speed makes very little difference in actual app performance or FPS(1-3%?)

A two stick kit will make it easier to OC since the motherboard will not have to manage the voltages on as many sticks.

Also, the cm hyper212 is a fine cooler as is. Why not try it out first?
Yes, you can replace the fans with higher CFM models for better cooling, but at the expense of more noise.
I am betting that for any sane overclock you will not find it necessary.
If desired, it is easy enough to change fans later.

I figured either someone would offer an alternative to the RAM with similar or higher specs, or tell me yes and I'd be fine and dandy =D

I'm also curious to whether or not my replacement fans will work or not since the pin headers are 3pin and the mother uses 4pin (not really sure how that would work).

Any advice is greatly appreciated.

I had this problem with my TT Frio and the second Fan. I also have the Vengeance modules, but just removed the cover for the DIMM. It's working with no issues at all, so you can get low profile RAM, change the orientation (if there's nothing blocking the FANs) or remove the metal/plastic clothing of the stick.

Cheers!

As long as your case airflow is good enough to prevent hot air from recirculating around the 212, a single fan is vastly sufficient unless you are overclocking.

You probably won't be able to use two fans on the 212 with finned DIMMs, the DIMM-side fan might hit the fins.

i was going to suggest:
CORSAIR XMS3 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 $94.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233203

though you do bring up a good point about OC'ing is easier with 2 dimms slots as opposed to four populated.

Since overclocking on K-chips is done by changing core clock multipliers while leaving everything else at standard clocks, picking memory is nowhere near as important as it was on Core2Duo/Quad where overclocking the CPU directly affected RAM clock.

The 4 pin cpu headers are intended for pwm(pulse width modulation) control.
If you use a 3 pin fan, it will operate at a fixed speed, but it is possible for some clever bios to detect this and control speed by voltage control.
Also, when using two fans attached to the motherboard, you need to disable one of the speed sensors or use an adapter cable. Noctua double fan coolers include such an adapter.

My advice is to try out the stock fan first.

The Cougar fans actually have less noise and more airflow (~17dba, I actually got the idea from a previous poster who recommended the setup). I'd really like DDR3 2133 with XMP but I was going by the QVL on the Asus website and I can't find the right RAM and I want the 16GB some video encoding and some photo editing. I've read up on it and I know that for gaming all you really need is about 8GB at DDR3 1333.

I'm really nervous about not following the QVL because I'm afraid of being stuck with something that won't work with my system.

and the memory controller is also different, where did it go?
on the CPU, right?

 

[joaompp]

I think you guys right, I'm definitely going to try the stock fan first, and see where I stand with that. Later on I'll probably switch all the fans in the case with the orange version if the noise/heat is unbearable.

Thank you very much for the information about 3pin and 4pin headers. Is there a good reliable website that you recommend so I can go to read up on that?

I do not see where the problem is with plugging each 3-wire fan in their own 3/4-pin header on the motherboard... one in the CPU fan header, the other in one of the 3-4 others present on most current boards.

I ran into this problem with the Corsair Vengeance 4x4 kit and CM Hyper 212 on my MSI Z68-GD65(G3) board. Reorienting the fans parallel to the DIMMs only aggravated the problem in my case. I ended up just offsetting the RAM-side fan about half an inch to clear the RAM-- note that not all cases will give you enough room to do that, however (my Corsair 600T has the extra clearance.)

I would recommend low-profile RAM to avoid the problem entirely, if you have the option.

Yes, the controller is in the CPU. That's not where the problem is.

On Core2, overclocking was done by increasing the reference clock because core clock multipliers were locked and that has the effect of inevitably overclocking everything else connected to the CPU.

On Core i3/5/7, the PCIe and other highly sensitive clocks are all derived from the CPU's reference clock, thereby making it nearly impossible to overclock by increasing it by more than 5-10%, which effectively locks it. The only way to achieve significant overclocks on i3/5/7 is to buy a CPU with unlocked core clock multiplier, in which case the core and RAM multipliers are completely independent, you can overclock one without affecting the other.

If you leave the i5/7 RAM interface at stock multiplier, the RAM runs at stock speed regardless of core overclock and the RAM configuration will have negligible effect on core overclock.

On Core2, the RAM overclocks directly with the CPU and if you hit the RAM's max overclock before the core's max overclock, it is the end of the road.

your looking at the wrong place; before the memory controller was on the northbridge. having all the dimm slots populated stressed the NB and would limit your overclock. that why some chipsets were better than others, like the P45.

now the memory controller is on the cpu and having more dimm slots populated will still add stress to the memory controller in cpu.

the symptom of stress i refer to is called heat. regardless of what you overclock, bclk or multi, having more dimms populated will generate more heat on the cpu and limit your overclock.

now i do not wish to hijack this thread.
