[56k]How to lower my PII 965BE temps @ 1.536v (NH D-14 w 2x slipstream 1900)

Evenin' chaps.
I'm peaking at 57c after 16 hours prime. I want to get it down to 55c like it was in my old modded iCan case with grill cut out. My temps went up when I put everything in a Haf 932 Black Edition. Overall temps went down obviously, but something is hindering my CPU temps a bit. Let me provide some details:

-Lapped CPU, been lapped even on my old case that had lower temps, so this was a constant
-Tested with MX4 and AS5 - 3 reseats each, all results within 0.5c of each other (I let the AS5 set for 2 weeks and got 1c cooler, so 56c load, still 1 degree to high.)
-surfaces cleaned with arctic silver cleaning kit (2 bottles) and coffee filters
-Applied tim using a line which is optimal for the D-14 concave ridges on the mating surface that spreads paste sideways, did too many reseats to find this optimal applying method. Like 25 reseats. The dot method also works well but the way the heatsink spreads the paste is it goes almost completely sideways so dot method doesn't cover left and right side of the IHS (while looking at a mobo mounted in a case) as the paste is derailed by the D-14 heatsink grooves to go up and down.
-The temps go up by 2c if I remove the 140mm Case Exhaust Fan (grill is not cut out)
-The slipstreams are ran at 1850 RPM both hooked to one 3 pin Y connector on the mobo's 3pin that has voltage control through bios, to control the speed automatically.


I guess easier way is to buy new paste, I have the following available Locally:

-as5
-mx2-3-4
-ic24, ic7
-thermalright cf3 chill factor III
-arctic silver alumina

What would be the easiest way to shave 2 degrees off my load peak temps?

The only thing i can think of is a mid case fan blowing up past your gfx card. My own case is set up the same way and i have an old 80mm coolermaster about 3 inches up from the floor of the case blowing air up towards the push fan on my hyper212+.

Temps seem to hover around 55° +/- 2° @ load for me.

have you tried with the cpu fans blowing up, and back fan out?
or will it not fit over your ram

build a shroud to go around your cooler?

I recently tried with the fan blowing up and I have a 120mm fan above that, but my load temps are slightly higher than it was when it was facing the rear exhaust fan. Most likely due to the heat the GPU emits and that is with a side fan intake blowing cool air for the CPU and GPU.

I can't change the direction due to the AM3 rectangular mounting system for the Noctua. Only works with Intel sockets as they have square mounting.

I would add a bottom intake and a second front intake. More cool air coming into your case will do better for your heatsink. Your D14 is just using the hot air already inside. A front mounted 140m fan blowing directly at the D14 will be your best bet. Give it some fresh cool air to use.
