I know there are many case variations that also affect this.

But, can you tell if there is any real drop in CPU temperatures
with 2 fans vs 1 fan?

Opinions welcome.
 
From what I've read: if there is enough case air flow the Cooler Master fan does very well. f the available air needs a boost you will see lower temperatures.
In general one capable fan will move as much air as is useful.
My feeling is CM fans are reasonably priced and reasonably quiet, match the oem or use any R4 around 2,000 rpm.
Thermalright are supposed to work well, single or double.
The case fan the heatsink blows air toward should be rated similar or greater cfm (unconfirmed).
 
Just a drop of 2-3 degrees in push-pull AFAIK.

You might get better drop if using push-push method,but it's still in debate.

My CPU is at 32C - 34c no OC, and at idle using one fan as a push into the HS.
I have a 200mm about an 1-1/2" away just above the HS. then is a second right
next to it, but not directly over the HS, more towards the front of the case.

The top back case fan lines up with the heatsink fairly well, but is about
3" away, its 120mm.

Thus my question, if it would be worth it or not?

adding a 2nd fan i dont think you would see a change in your idle temps however under load i think you would see a 2-3 degree drop. at least that is what i have seen with mine.
 
OK, thanks thats helpfull.

I have not seen anything higher then 50C at load (after playing a game for an hour
or prim95).
 
Yes, you would see a change under load temps. I would say around 4-5 degrees actually. But on the other hand, more dust and stuff.

with the 200mm fan there i wouldn't bother with a push pull config since its possible you may hurt the cooling performance due to the difference in fan speeds even 3" away the 200mm is still drawing heat directly away from the heatsink.

Yep, I see your point and agree.

After some thought, I'm not going to change anything, as it may be
counter productive to my case fans.
 
I`m running 212+ in push/pull. What I can tell is that after adding a second fan load temperatures dropped by a few degrees.
