I just installed a Katana II yesterday on a year old Pent 4 D 2.8, And it took my breath away. It ran at human body temp 98°F [37°C]
with 74°F [23°C] ambient room temp.
Now in comparison the Northbridge is on fire at an untouchable 140°F [60°C] with its stock Asus (c) alu cooler.
I would like you to make a version of the Katana II for Chipsets, thats thinner, or offset.
I was so impressed that I would just buy another Katana II and adapt a vga/chipset bracket for it. But its so close to my cpu and existing Katana II that one of the mount/retaining hole is under existing cpu's Katana II.
