Here's a rough diagram of my air flow.
1. Intake - Mid level Inside drive bay pointing vertical. (Would it be a good idea to rotate that fan pointing toward the back?) I think there's room to get a 150mm fan fitted vertically in there.
2. Intake - Low level
3 & 4. Exhaust
5. To be replaced with new cooling by CM.

The noise doesn't bother me within reason. Although, the GPU fans 1+2 are quite loud though in comparison to the 120mm's.

What is the logic rotating it horizontally ? Yes, set it vertical, pulling air inwards the end. Like this:



You can keep one or two. If you keep two, you can set them to be slowly rotating (<700-900RPM).

Regarding 3&4 exhaust, you might alternatively don't need those if you buy "reference design" GTX, which have exhaust outside of the case (as opposed to inside like the multi-fan solution from Asus, MSI, Gigabyte,...).

The previous pic I posted showed the positions where they are now. That fan definatly needs to be rotated. 140 or 150mm fan for that position will work wonders for the air flow. :)

point the fan into the rear exhaust, NEVER into the PSU, if possible - I did it once, and when the CPU is under load, PSU draws in hot air and its fan speed+noise increases significantly
Rendering is magic.

I see what you mean. The heat gets dissipated out the back as opposed to back into the case which would case more heat overall. http://www.overclockers.co.uk/showproduct.php?prodid=GX-205-OK

As opposed to the ASUS one I was going to buy: http://www.overclockers.co.uk/showproduct.php?prodid=GX-352-AS.

Thanks for that.

Thanks, In this case the PSU is completely sealed inside and the air is drawn from the outside through a filter underneath. See here:

Swapped the CPU fan around to this position (Pushing up).


The results are both around 7-13.5degC lower than before the post below.

Below is two tests for temps on my machine over a 10min period with a 10min lay period between test. I've tested with the case open and closed. I'll post my findings once I get my filthy hands on the new cooler. :]
test 1: Temp Before Upgrade - Temp With Cover 73.75Avg
test 2: Temp Before Upgrade - Temp Without Cover 59Avg

And some bench tests below. It comes 2nd in the list here to the much larger CM Nepton H110. The NH-D14 is 8°C hotter on the highest end Over-clocked bench test.

I know the fan is probably sucking in hotter air in this position next to the GPU but this is as good as I can do until I get thermal paste and the rest of the upgrade stuff.

Just thought I'd follow up on results. And it worked out well. Defiantly was due to the old heat-sink not working correctly. I think the cooling plate may have been faulty out of the factory. Either that or the paste wasn't properly applied.

Anyway the results with the new H110 from Corsair. I used the benchmark scene found on this forum.

Stock @ 3.2Ghz (CPU: Max avg. temp 45dC)
Corona Renderer Alpha 4 benchmark scene
 Living room 100 passes
Intel(R) Core(TM) i7 CPU 965 @ 3.20GHz
Time: 0:6:48, Rays/s: 3,114,342

OC'd @ 3.7Ghz  (CPU: Max avg. temp 70dC)

Time: 0:6:28, Rays/s: 3,274,014

OC'd @ 3.9Ghz  (CPU: Max avg. temp 74dC)
Time: 0:5:59, Rays/s: 3,547,260

OC'd @ 4.0Ghz  (CPU: Max avg. temp 75dC)
Time: 0:5:30, Rays/s: 3,854,289

OC'd @ 4.160Ghz  (CPU: Max avg. temp 70dC)
Time: 0:5:19, Rays/s: 3,986,984

1min 30sec shaved of which isn't to shabby. The temps are much much better. The last OC'd @ 4.160Ghz had been OC'd for two days after the previous test at 4.0Ghz. I just wanted to see if was stable enough to post.

IMPORTANT:
If you do happen to purchase the H110 DO NOT USE a screwdriver like a youtuber with a million + subscribers tells you. You'll end up f******* up the backplate because it's only made for hand tightening. I got one sent to me as soon as I emailed them. I'm not fortunate to have an access panel to the back of the CPU so it means having to rip out the MB once again.. noice!!! :(
