Recently I got a second fan for push-pull on my Cooler Master Hyper 212 plus. I have an i7-930 OC'ed to 3.5Ghz with 1.13v. This is my first time with push-pull.
Before, my idle temps (for my hottest core) were 37-38 celsius (RealTemp) and now they're 36-37 Celsius. Prime95 used to max at 62 Celsius, but now it's 60 Celsius...
I am feeling a little underwhelmed, should I be getting better temperatures than this, or is this normal for push-pull??? It doesn't seem worth it.....
Well I am using a tru, but my temps improved by about 5 C when I put the second fan on. However I think I also changed the orientation at the same time so it may be less...
I wouldn't say the results are unexpected. You've got an excellent cooler and the addition of another fan is showing some benefit. Perhaps it is the type of fan or the fan speed or the CFM's that are having you feeling underwhelmed.
Do you know the particulars of the fan you've added?
I added a second CM fan to my Hyper 212 and got similar results, about 2-3C drop at full load. It was about what I expected I would get based on reviews. However I did not like the added sound, it created some weird harmonic tone that I do not like so I pulled the second fan back off. Although overall I am pleased with the performance of the 212, I may try my luck with a Thermalright Silver Arrow to see what kind of improvements I can get at 4.0Ghz on my i5.
I wasn't impressed and didn't even see the 2-3 C difference. but I have a 120 exhaust right behind the heat sync so the hot air is already being pulled out. I have an open fan slot in front (on top) of the sync so I will see if bringing in cool air will change anything (it will).
THANK YOU so much guys!!!
This really helped!
I now have a reason to not waste my time taking the push-pull off and moving it somewhere else (where it's not needed).
btw, the fan specifics are (I think):
Stock Cooler Master Fan: 22-77 CFM
Antec Fan: 26-79 CFM (might be off a bit).
if you decided to install a push/pull configuration on the hyper 212+ where do you put the fan headers? Can you plug them both directly to the mobo fan headers? or is it better to connect it to the PSU or a fan controller?
