Welcome!
Here are the different tests I ran with my rig with the HYPER 212 EVO. All my rig info is in my sig. Case is Rosewill R5.
ALL OF THESE tests were done on Intel Burn Test at Standard settings, not prime95. My rig is OC'd to 4.5ghz. i5-3570k. Rest of info in sig rig.
--I used the 3 stock fans that came with the case. (2 were installed as front intakes, 1 was installed for a rear exhaust)
--I used the stock Coolermaster fan that came with my HYPER 212 EVO
--I purchased a DELTA PWM fan. Link here: http://www.newegg.com/Product/Product.aspx?Item=N82E16835706036
My case does have a rear grille. I think this is very important to the test data versus others tests.
In the data sheet and graph:
CM - Coolermaster stock EVO 212 fan
D - Delta PWM fan referenced above
PUSH - Push setup on EVO 212
PULL - Pull setup on EVO 212
STOCK - fans that came with my rosewill case
I also added a fan to a top exhaust spot and behind my HDD cage in my case in two different scenarios. Last but not least, I ran a test with my preferred setup with my front intake fans MAX rpm and MIN rpm.
Also, I did not test ambient temps. However, idle temps were all within about a degree of each other. I know TOA is important. I am more concerned LOAD temp.
CASE PICS TO GET AN IDEA:
1:
2:
3:
Without further adieu...
SPREADSHEET:
GRAPH WITH DESCRIPTIONS:
GRAPH WITHOUT DESCRIPTIONS (NUMBERS USED):
GRAPH WITH DESCRIPTIONS (DIFFERENT VIEW):
So, I found some interesting things that conflicted with others findings and confirmed other's findings.
1) The Delta PWM fan in the pull position WITH A REAR GRILLE had the WORST results.
2) Swapping the Delta PWM fan for the Coolermaster in the push position without changing anything else yielded better results. (A whole 1.25 C difference)
3) The Delta PWM fan in the push position WITH A REAR GRILLE without a rear exhaust had WORSE results than the same test WITH a rear exhaust.
4) Adding a top exhaust right above the EVO added temps for me.(BELOW the top grille) ALSO, changing the same fan to the HDD cage increased temps as well. (Very slight, almost unmeasurable)
5) Temps decreased with a lower rpm front intake fan speed than a higher one. (This one gets me. Confirmed with 3 different tests in MY case).
Last but not least, before the new fan configuration my temps were AVG 75.75 during load, after the best fit It is around 73.25. A 2.5 C difference.
Recommendations:
1) Listen to the findings. Don't expect a huge temperature decrease when adding fans to the 212. Expect 1-3 C range at best depending on setup. (Although I didn't test 2 of the same exact fans in a push/pull setup, I don't see how some claim they get 5+ C better temps)
2) "More fans are better" - isn't true. In fact, I got better results with the same setup WITHOUT a top exhaust and WITHOUT the same fan in the HDD cage fan spot.
3) Last but not least, if you are wanting a CHEAP solution to decrease temps 1-3C with same OC, I would recommend buying ONE decent fan and either replacing your rear exhaust with it or putting the stock CM fan as a rear exhaust and replacing your push setup with the new fan.
UPDATE (MORE TESTING):
SPREADSHEET:
TEST 1:
TEST 2:
TEST 3:
TEST 4:
Things to note:
1) Nothing in the most recent tests decreased my load temps.
2) In fact, everything increased my load temps except for a top back exhaust above the grille (Test 2). It stayed the same.
Conclusions:
Just because you see testing done here in this thread, by other members on OCN, and all over the net, doesn't mean that it will apply to you in YOUR case, YOUR build, and YOUR setup. The best conclusion recommendation I can make is to do YOUR OWN TESTING to see what works best for you.
---I hope this guide helps people and encourages our users of our great OCN community to do testing of their own!
---That's about it. Questions, comments, criticisms, thoughts, concerns, debates appreciated! CHEERS!
