try getting vga silencer rev3, by arctic cooling. try asking around for 2nd hand, or get from bulk. takes away 1 pcie slot, but exhausting the hot air outside is a big plus. also the heatsink is large. em.. wait.. im not sure whether it fits.. lol~

but anything from arctic cooling is nice if u ask me. extra few rm10 is not much compare to the satisfaction u'll get. if u r getting the coolviva, or vantec iceberg, then later though it wasnt enough.. then u'll be spending more searching for something else, then ur budget suddenly doubled, and already enuff to get the styrin ku formula in the first place..

anyway, it's ur call..
