P-50 Armorsuit airflow problem

I'm getting some nasty temps in my case and I'm wondering if the airflow is just all wrong, or if its just too hot in my apartment. My i7 is idling at 45-49C. Temps go slightly down with the case side off.
All 120mm fans are Scythe 1200rpm except the stock scythe on the Mugen 2, I think that's 1400rpm. The 140mm fans are stock Lian Li. Here is how it is setup:

Specs? are you overclocking? what heatsink? you applied thermal paste correctly? room temp?

But those temps aren't terrible..
 
Cooler is the Scythe Mugen 2. I'm not overclocking at all. I used a BB sized dot of AS5 on the heat spreader.

Try turning frontmost 140mm to intake/disabling it, there's good chance that it's now just drawing out cool air on its way to CPU.

Also putting fans in series rises only pressure capability, not airflow...

They are mid range RPM slipstreams, and I hear they have low static pressure, but there's fan filters in the bay covers, so I thought it would help, I had the extra fan anyways. I tried turning the front 140mm inwards for a while and it didn't change anything, I'll try disabling it though.
 
I disabled my top-forward fan and put a piece of card-stock over it to block any other airflow. My temps didn't change, and as far as I know, they didn't change from the extra front fans that I can tell. I may just need to remount my heat sink. Why would temps not change with massive fan changes? Is the airflow terrible, or the heat sink is just performing the best that it can right now?
 
Case fans not affecting to component temperature means it's up to cooler of that component.

It's Noctua S12 which can't push or pull air.
 
you probably have a high leakage chip. i7's already run pretty hot, and having a high leakage one will put it way up there.
 
There is simply no way that your case (or any case, for that matter) is responsible for 49C idle temperatures.

My guess is that the heatsink isn't attached properly.
 
So I reapplied thermal paste, using a horizontal line instead of a BB. I also rated my cool 90 degrees for kicks. I booted up and in the bios it looked fantastic at 33C, but once in windows it doesn't seem to have changed. I'll see once the thermal past sets. I remember seeing the Scythe Mugen 2 rated extremely well, top 2-3 coolers. But I'm not liking this very much.

Haven't heard about any motherboard capable to showing actual core temps instead of entirely wrong temperature measured from useless place.

How temperature behaves when stressing CPU?
Was just thinking that maybe that particular CPU has sensors with abnormally high lowest value. (Q9550 I have has three sensors sticking to 38C as lowest value)
 
What program should I use to really stress it? When I play games I never see it go over 55 or so.
 
Here's what I would do. Keep the front lower 120 as intake, and the front upper 120 as intake. Take the second front upper 120 and put in on top of the heatsink, next to the 140 exhaust, and run it as an exhaust (upwards). Keep rear 140s as exhaust. Keep the rear 120 as exhaust and move the current 120 on the heatsink to the bottom (pointed upwards as exhaust). This should yield an airflow from cold to hot of bottom front to upper rear. Front top 140 is optional.
