I'd like to ask the community for a solution which would help me better cool my mobo's NB. My hardware:
Case: Gigabyte 3D Aurora with a front 120mm fan and 2 120mm rear fans (Topside PSU placement).
PSU: OCZ ZS 750w
Mobo: Asus Crosshair V Formula
CPU: Amd X4 955 (3.6ghz OC)
CPU Cooler: Noctua NH-U12P (single fan)
Ram: Patriot 2x4 G2 series 1333mhz
SLI: 1 Gigabyte GTX 460 1GB
1 MSI Cyclone GTX 460 1GB
Despite the immense heat generated by the 2 video cards, everything remains at reasonable heat levels. Except for the Northbridge, which reaches (and might even surpass) temps of 70°C range when gaming. I find that to be extremely dangerous and have set my mobo to shut down when it reaches the 70 peak.
I have yet to replace the stock paste of the NB, but I have checked my airflow (with smoke) and there's powerful airflow around the CPU (blowing heavily out the back because of the 2 120mm case fans + 1 120mm cpu fan), aswell as good airflow around the video cards.
To this end, I'm looking for a possible cooling solution other than weird modding and/or water cooling for the NB.
I will gladly consider all, and every possible suggestion.
