And a GF4 Ti4200 OVERCLOKED with a Zalman ZM17?!? what the hell? and its totally stable?? i dont believe it...
Yeah, this sounds quite interesting. I have attached a ZM17 into a GF4Ti4200, and with default clock speeds in a ventilated case (tried up to 12dB papst in+out @ 12V) I started getting visual errors after a couple of runs of 3DMark. I now run one papst @ 5.5v over the GF4 with a Zalman fan bracket and another papst @ 5.5v as a case exhaust and everything works fine.
I'd think that with good case ventilation (or perhaps undervolting) it would be feasible to run GF4Ti4200 fanless with a ZM17, but IMO overclocked & no ventilation sounds a bit (fried) fishy.
