Can this be run safely without a fan?
It has the type of heatsink the kinda forms a sandwich around the GPU and memory. The fans are annoying my wife since the bearing are bad.

I have a fan blowing from the front of the case towards it but it still gets REAL warm ( estimate of about 130°F+) after playing Halo for only 30 mins. I do not want to fry this card and do not have to available $$ right now to get a VGA silencer. I would like to do this as a "stop-gap" method until I can afford the VGA Silencer.

Well, the VGA silencer will not fit on Geforce4 cards. Right now its Geforce3 and Radeon 9500, 9700, 9800 only. You'd have to use a Zalman heatpipe.

As for whether that heatsink is enough to cool the card passively, I say grab one of the zalman fan brackets to blow down on it. I'm sure it'll be okay that way. I have one of these and I wouldn't be afraid to unplug the fans in the above situation, although you might want to redo the thermal paste with something worthwhile and replace the lame plastic pins holding the front part of the heatsink on with some nylon screws to increase pressure.

I had the same sort of problem with my Asus 9280TD Ti4200 card. I pulled the tiny fan off, and mounted a Panaflo 80L right in front of it. So the fan is blowing air (quietly I might add) onto the stock heatsink, and it's been running fine for a couple days.

I can play games no problem.

I used to have an A280TD (Ti4200 and same HS, I think) on which I accidently stopped the fan and then ran benchmarks for a while (about an hour or two, I think). The thermometer I had attached to the board didn´t report higher values than 80-85 degrees C and when I lost that reading (stilling having no clue of my mistake) I still continued to run the card for some time and didn´t realise my mistake until artifacts began to appear on the screen.

I´d say that you unfortunately need some sort of airflow over that HS if you want to be sure. On the other hand, if that card is anything like mine, you shouldn´t need to worry to much if you do not experience any artifacts.

Thank you for the help

like cob i've been running an 80mm fan at around 1400rpm for 4 mths now without any problems at all, runs much cooler than the stock fan and much quieter, silent really to all intents and purposes

Last idea......... I was thinking about unplugging the fans and installing a 92mm fan at 7 volts blowing from the back of the card to the front ( i.e. ram end to video connector end ) . Do you think this will be enough? The fan has an output of 2500rpm/45cfm @ 12volts. I think that this might be quieter than the supplied 50mm fans ( yuck)

I think it may work. Your card will of course be hotter than with the stock cooling, however, you have 40 degrees headroom:)

i think you'll get better performance and results if you position the fan so that it blows from the rear of the case towards the front, this way the air that has blown over the card will go upwards inside your case and get sucked out by your exhaust fan(s) at the top of your case

I think it would be more efficient to glue the fan directly to the heatsink using rubber spacers or to make something similar to this (the text is in russian but the pics speak for themselves).
