Replacing the CPU fans and buying a CPU cooler

Purchase date: Tomorrow
Budget: $70

Ok, I'm headed off to Frys tomorrow to buy some parts. Mainly, I want to replace the stock fan that came with my case and the Dynatron fan for my CPU. I'll probably OC tomorrow too so I want to prepare my coolers.

PCU: i5 760
Mobo: Gigabyte P55A-UD4P
Case: NZXT Lexa S 94 5slots for fans (2 top, 1 rear, 1 side, 1 front) with fans included (43CFM, 23dB)
RAM: 4GB DDR3 1600MHz Corsair CMX4GX3M2A1600C9

Cooler Master Hyper 212 plus Cooler ( 13-32 dBA noise 21.2-76.8 CFM)
Apevia 120mm Fan UV Blue (29.67 dBA 63.85 CFM)

The question is...

1. Will the CM Hyper 212 + fit in my case?
2. For aesthetics, I'd want to replace the fan of the CM Hyper 212+ but add 1 more to make a push pull configuration xD. Would I lose out greatly in airflow if I change fans?
3. Should I replace all case fan with the fan I mentioned above for increased airflow?

Additional note: My case is literally next to an electric fan. The noise produced by the computer is inaudible compared to the noise by the fan.

  1. Best answer
    1. it fits in a standard mid tower case if you remove any side fans by it
    2. 2 fans would give you better airflow than the stock 1
    3. totally up to you if your airflow is good theres no need to
  2. The 212+ should fit in your case if it's too tight remove the side fan as simon12 suggested.
    The replacement fans are totally up to you.
    Personally if i replace fans i go for the quietest ones i can find.
  3. I've been going for the quietest fans possible too. I have the same number of fans installed in my RC-690, and even though they are individually quiet, the case "roars" when on; I've finally gotten sick of it and will be rebuilding in a Silverstone case this weekend. I'll be giving up some of my fans, but I've only OC'ed my Q9450 to 3.2, and don't have heat problems.
    I am also going from an Arctic Cooling Freezer 7 Pro (which whines) to a CM 212+, which should fit without problems.
  4. 1. The stock HSF is fine, even for overclocking. Don't feel that you have to change it.

    2. Unless you have one of those dumbazz cases with the bottom mounted power supply, all you need is one 120 mm exhaust fan in the rear of the case. Front intake fans are of very little benefit, side panel fans are disruptive & should NOT be used. Also, removing the side panel renders the case cooling fans ineffective.

    Have a look at this:
  5. Them stock HSF is not fine for anything more than minor overclocking and is not that quiet either. You can get a better and quieter HSF for very little so there is no reason not to get at least the coolmaster Hyper TX 3 but the 212+ is alot better (8C in my tests at 3.7GHz see ).
