Quieter Coolers for the Mac 7800 Graphics cardReturn to News Page
Mac Nvidia 7800GT with NV Silencer 5 Cooler

Arctic Cooling NVSilencer on OEM Mac 7800GT card
I just wanted to report a successful install of an Arctic Cooling NVSilencer 5 (rev 3) on a PowerMac G5 Quad with a 7800GT. The stock fan sounds like a small tornado, but the AC Silencer is dead quiet and my GPU runs 10C cooler at idle and 15C cooler under full load (during Quake 4 testing, Ultra High, 1680x1050, 4xAA) according to Hardware Monitor.

It's a bit of a tight squeeze (the nuts that mount the heat sink hit the plate below the PCI-E slots) and it takes up and extra PCI-E slot, but it does push the heat out the of the back of the case.

Now to see about some over clocking :-)
