Hey there

I installed Cooler Master Hyper 212 led CPU cooler (it was very stressful!). Now its fan covers first memory slot. I am installing 2 memory sticks in A2 B2 but hope to install 2 more later (in A1, B1). If I leave the Cooler Fan on the right- I will not be able to do it. Question: is there any specific reason this fan should be on the right side where the memory is, as shown on the box picture and instructions? Why not put it on the left side? I am looking on the cooler- it is nothing but thin metal plates and metal tubes going through the plates. The wind from fan will go through the plates to cool the metal tubes. It should work from left to right the same as from right to left, right?

Thank you.

When you install a tower cooler with the fan to the ram side the correct way is to face it so that it is pulling air from the ram side , pushing it through the heatsink & towards the rear case exhaust (the 212 evo has the fan Pre fitted to its black plastic holder in this orientation)
& that's the main reason - because generally cases have a front intake to rear exhaust airflow setup

If you want to swap the fan to the back of the heatsink you should also remove it from the plastic fan holder & reverse it so that it is still pushing the air in the same direction.

You lose some cooling performance this way though over the standard fitment.

Only slight issue with moving the fan is that it will not be quite as effective, so the CPU temperatures will be a little higher, but only by a few degrees at most.
Unless you intend to overclock the CPU to within a micron of its life the temperature issue is nothing to worry about, if you DO to intent to overclock heavily, you could always swap the supplied fan for a stronger PWM part, look specifically for those with a high static pressure.

I cant see what is the difference. Is it something inside the metal plates that is invisible to the eye? If I place the fan for air to go IN to the cooler, it should not matter left to right or right to left. What, you think, would make it less effective?

Thank you.

I did not account for the flow in the case. It makes sense. But still. you mean- reverse the fan so it blows OUT of the cooler as if it was sucking air through instead of pushing? I don't like it. But I think- if I ignore the air flow in the case and put one fan against the flow, blowing left to right IN to the cooler- how bad can it be for the entire air flow? I have huge case (by mistake). So the air would have to blow through the cooler and then have to come up on the other side, join the case air flow, turn around and come out of the back of the case. Not ideal, but I don't see big difference. I have 3 other builds running on the stock coolers- how bad can it get? It is 7700K, but I am not overclocking. My memory is 3000MHz so I will be using XMP profile- I don't know if it would affect CPU.
Thank you.

If you push thru the fins towards the front of the case you're blowing pre-heated air across the ram sticks and interrupting the flow. Not a good plan.

Either put it on the back side in a pull configuration blowing out the back, leave it push on the right side but slide it up higher (it's adjustable), or just buy low profile ram (those tall fins don't do much).

Thank you for your post. Ok, you making perfect sense- I don't want to blow hot air to memory. But I can not buy new memory. My memory cost over $200 (2x16Gb Corsair 3000 Mz). I can not send it back now and would not want to mix and match different kit.

I was wondering if I could lift the fan up. It would need to go up at least 1" to 1.5 inches. Will it significantly affect my temperature? (Note that this rig is not for gaming but for audio and should not overheat, but it will be left on for at least 48 hours without sleeping). My 3770K system has strange restarts when I am not around. It has stock intel cooler- wondering if restarts are due to CPU overheating- it happens randomly. So you think lifting it up 3rd of the body would be ok? Thank you.

It's only a matter of removing 4 screws. Matt's advice is one of wisdom. An yes you want a pull configuration, meaning it's pulling the air from the front of the case . You NEVER want to go against the flow in a chassis. You are constantly exhausting the heat back into the case.

You know? What did I do when I built my PC? I KNEW what problems the 212 could impose. I chose LP RAM. It doesn't say it but they are low profile. This all could have been avoided with the right RAM. There's about 1/4" between the base os my fan on the 212 and the RAM

And I like a cool CPU so I added another fan

Just go ahead and make sure the fan is exhausting the air towards the rear fan on the back of the case. That's your best cooling option short of replacing the RAM. They also sell slim 120mm fans. Not sure about high static slim fans but a thinner fan is an option.

Another option is simply sliding that fan UP a little, The grooves on the 212 travel the entire length of the cooler making the fan's height adjustable. Certainly not an ideal fix but I think I would prefer that over having a pull configuration.

Your post came later- probably due to the pictures. Thank you. I actually started a thread here asking if this cooler would obscure the memory and only one person replied, stating it will not. There were couple of other threads I found that stated that it will not. It is hard to tell by the pictures. I don't know why Cooler Master chose such a design. They should of make pipes longer and lift it 1" more. It is on them. They should of put warning on the product page. If it is there- I did not see it on Newegg. I have to tell you that picture instruction was awful and it was very stressful to install as it had all these other models options and I almost took it off thinking I used wrong stand offs because I found 4 stand offs unattached- which were for another motherboard. I am very dissatisfied. I hope it works better as a cooler than its instruction. Thank you again for your help.

Installing my 212 was the most labor intensive part of my build. I thought installing all the case leads was tedious. The 212 does take some patience. Was it worth my time? Absolutely.Please let us know how everything turns out.

OC'ing?

Astralv - you have to take into account the 212 has been around a long time.
Its a budget 'performance' cooler - it therefore is aimed at the budget market really.
Many cases under the $70-80 mark have a max height limit of 160mm which the 212 just fits.
The evo is aimed at those.
There are many many alternatives now that have a slight bend on the heatpipes to offset the cooler to the rear & miss the ram slots entirely.
The blame lies on corsair with those silly vengeance & dominator heatsinks really - just no need whatsoever for the height on them - they do nothing at all.
I had a 4 stick kit simply because it was offered to me dirt cheap otherwise I would have never bought it.

I raised the fan on mine to accommodate but the aesthetics through my windows panel bothered me.
Replaced with a silentium fortis 3 now because of that.
I rarely recommend the 212 anymore because of the fitting , its an absolute pain compared to a lot of similar priced coolers.
