Please log in for more thread options Hi Folks, I bought an Antec quiet case and a quiet power supply, Athlon64 3200 and MSI K8N Neo MB. The system is really quiet except for my video card - Asus GeForce4 Ti 4200-8x. The fan on the video card is really loud. I can control the CPU and case fan speeds, but I don't see any way to control the fan on the video card. I guess it is not a good idea to disconnect that fan. Any ideas? Thanks, -- Jeff | ||||||||||||||||

Was it always this loud or has it gotten louder? Some cards (I don't recall on yours nor on TI4200 in general) have a integral fan speed thermal control, BUT all it really does is change the fan RPM from pretty-loud, to even louder. Point being, you might not get it quiet enough for your personal tastes but increasing the airflow past the card may help some. One way to do that is to leave the adjacent PCI slot empty, and that slot's case bracket cover all so the system's intake or exhaust fans passively move some air past the card/sink. >I can control

Thanks, Do not disconnect it, it is needed. If the fan has gotten louder (or for that matter, even if it hasn't, since at this point the card and fan are aging), disassemble the fan, taking it out of the 'sink, then peel back the label carefully (not touching the sticky-side so it will re-adhere to the fan again as much as possible) and put a drop of heavyweight (almost grease-like consistency) oil in the bearing. If that doesn't help enough, your remaining options are to replace the fan alone (hard to find suitable replacement on special OEM proprietary 'sinks), the entire heatsink, or your preferred method of fan speed control to reduce the fan RPM. Odds are good you would be able to reduce the fan speed some with no ill-effects, providing the card isn't sandwiched in next to another card in adjacet slot and has the case bracket cover off that next slot. Controlling fan speed depends on your ability to do some basic electrical work, soldering and heatshrinking an alternate lead to the fan, or placing the control mechanism inline on the fan lead if it will be entirely contained on the card itself. If I were _guessing_, the fan might respond well to a roughly 47 Ohm, 1 W resistor placed in series on the + power lead. This and any other method depend on your willingness to splice, solder, etc. Aftermarket 'sinks can work too, though at this point in the card's life, due to it's age, it seems a bit of an overkill to buy a relatively expensive passive heatsink like a Zalman something-or-other, and if you just get a lesser quality fanned sink then within a year or two the odds are fair that again the fan will be failing. One alternative is to put an old pentium 1 heatsink on it, one that uses a standard 40 x 10 or 50 x 10mm fan (but ideally, at least a 15mm thick fan for best fan life though that begins to take up a lot of space onto the point of blocking 2 PCI slots instead of only one). With a standard fan on the sink, if fan fails later then it's rather trivial to buy another standard fan for it. 40 or 50 x 10mm fans are quite common. However you may face similar issue that the fan needs it's RPM reduced for lowest noise, so if it were me, I'd first try reducing the RPM of the current fan after lubing it. | ||||||||||||||||

> Asus GeForce4 Ti 4200-8x. I have an Asus Extreme N6600GT and it also has a noisy fan. Oddly enough, it makes more noise when the fan is running slowly than when it is running fast. I'm not sure if this is exceptional or not, since I don't have any other similar models nearby to compare it with. The temperature is okay, though, being around 51° C most of the time and rising to perhaps 68-72° C when I play _The Sims 2_ (the shutdown temperature limit is 127° C). -- Transpose mxsmanic and gmail to reach me by e-mail. | ||||||||||||||||

I replaced the PSU with an Antec fanless unit. I unplugged the CPU fans which raised the CPU temperature from 39C to 42F (big CPU copper heat sink). I also bought a 120 mm Antec case variable speed fan which is not annoying. The Matrox Millenium P750 video fan, on the other hand, really grates on my nerves. If I didn't have 2 digital LCD monitors, I would just go with a heat sinked analog video card. I wonder if it's possible to change the fan to a big heat sink? It worked with the CPU. | ||||||||||||||||

Ignore my previous post. I solved the noisy video card fan problem. | ||||||||||||||||
