Single CPU Fan (Pull?)

I have a CM Hyper 212+ CPU cooler and my CPU fan at the moment is blocking one of my RAM slots. I have Corsair Vengeance 2x4GB installed at the moment, and the fancy heatsinks that comes on those are quite tall.

There is not another possible way that I could think of orienting my CPU fan so that it will not block the RAM slot. So I was wondering if I switched my CPU fan to the other side of my CPU cooler, so instead of "pushing air" through the CPU cooler, it would just pull.

Do you guys think I would notice a significant temp increase? Or is it a bad idea? At the moment I idle at about, 20-25C. I usually never go above 40C even when gaming.

If you were wondering why I don't just flip the CPU fan on the other side and make it push air that way, that's because my case exhaust fan is right behind it so initially my configuration was to push and my exhaust fan acting as a "pull", but this method blocked my RAM slot.

I also cannot reorient my CPU heatsink so that it will be horizontally (long) because then the CPU heatsink will be the one blocking my RAM slot.

My only other option is to get a liquid cooling solution, but I have an AZZA Solano 1000 chassis, and preferably I wanted the Corsair H100i but i don't believe my case will fit the radiator without some modification of some sort. There is however the Corsair H80i, which might be ideal...

- If this helps I also have a 230mm exhaust fan at the top of my case also.

Any ideas? Thanks.

for better results make sure your rear pc fan is not a stock pc fan get a good one like spectre pro this will allow for a wind tunnel effect if you have it pulling

e.g example via my dodgy diagram

[] heatsink
// fan
>>> airflow
rear of case [[

it would work like this

[]// >>>//[[>>>>>
if fan was on side of ram slots
//[]>>>//[[>>

pushing the air would require the rear fan to work harder and wouldnt get as much air shifting out the case

i saw when i did a duel fan configuration with a good rear exaust that it worked well and before i was using 1 rear pulling which kept my temps down

when pulling you will see a temp decrease providing your rear fan is good at pulling and has high cfm

in order to free up your ram slot 1 and 3 you could get low profile vengence ram heatsinks also called the LP version they are exactly the same as the tall version i used both for a kind of snake effect

1/3 LP 2/4 high rise
