Core fan Abnormal - Fan Speed 0 rpm - System slowdown
I have replaced cooling fan on graphics card with a new fan.
I don't see any improvement.
Is it because of a power cables on new fan are directly connected on power supply instead of connecing them on graphics card fan cable connector?
It is a same 3pin connector but it differs in its size.
Graphics card core engine still show 0 rpm. The graphics card may not recognize a fan probably and that's why te computer sysem slow down.

Re: Core fan Abnormal - Fan Speed 0 rpm - System slowdown
Well, since you connected your fan directly to the power supply, you are not getting any feedback thru the graphics card interface. This doesn't mean there is a problem since your fan is running full speed all the time, it is actually better and you should be able to see a difference on the GPU temperature.
If the GPU temperature is still too high and the fan is running at full speed, did you apply a thin coat of thermal paste on the heatsink? if not, there is your problem.
Now just to be clear did you connect the fan to the power supply or to a spare motherboard connector. If you connected to your motherboard, you need to go in the BIOS and change some settings regarding the fan speed (let me know if this is the case and I'll help you further about that.)

Amazon sells a 40mm fan for about 4.99, it is a 3 pin setup (may be available in 2 pin).
But that should be about the same size as your existing card fan. Just watch for height issues on the new fan. This would be easier that trying to replace the existing fan, as it is most likely powered through your video card port and would be difficult to replace.
As far as mounting it to the card, try just a couple of drops of super glue on the outside corners of the fan, then mount it to the heat sink on the card, the existing fan is probably mounted w/ screws, you may get lucky and the new fan will match the existing holes, otherwise just super glue it.
Not a factory fix, but it will work!
Take care Dave
Your graphics card was overheating and might be toast. You can try and Purchase a custom Graphic Card cooler for your graphics card. If you decide to purchase a new Graphics card go for an ASUS or XFX one.
You can see if the fan is getting pluged up with dust. Yes I have seen lots of these do that. You can also take the fan off the card and clean it. or replace the fan..If you are having trouble already with gaming it is because the card is getting way to hot..
The amount that you can overclock you're video card differes for each individual card. The limiting factors are temperatures and stability. If games start crashing, etc you should back off the overclocking. Also keep in mind the temperature of the card. Increasing fan speeds will lower the temperatures of the card. Increasing the fan speed (as long as you don't go beyond 100%) will not damage the card... It will be louder though. For the 9800gt, the maximum temperature before damage is 105 degrees C. Try to keep the temperatures at 80 or below optimally. Increasing the fan speed is the best way to accomplish this.
CHA_ fan slot is Chassis fan slot (case fan) you can use it for anything you'd like really, it it recommended to have a fan or 2 sucking the hot air out of the case and that connector would be perfect for such fan.
I am assuming the noise is an abnormal squeel or such as opposed to the normally annoying fan noise that most cards have. If so...depending on the fan and card model, it can be replaced. But if you are like me, you want it fixed now. Most Fans are sealed and if the bearings go, well thats it for that fan, but some have a sticker on the center of the fan. i you peel that sticker off you might see the bearing, and if you are lucky enough to see that, drop ONE DROP of 3-in-1 oil, or such. if you cannot see a bearing and you cant find a replacement, you should still be able to remove the fan (Carefully). with the fan off, you can soak it in either wd-40 or light oil. after this you must be sure to clean off all excess oil (compressed air is best) before reisntalling.
A while back I had a computer that was having all kinds of video issues after it had been on for a little bit. I pulled the video card out and like you was able to free spin the fan and didn?t see any dust worth mentioning. Also like you I ran the computer with the case open to verify the fan was actually spinning but noticed there really wasn?t much air being moved. I removed the fan from the card and to my surprise found that the cards heatsink directly underneath the center of the fan was blocked with a solid ball of dust I couldn't see before. Cleaned that out, reassembled and I was good to go.
If that doesn?t do it you might consider replacing the card fan. They?re small, cheap and run full board on gaming machines. Since you?ve gotten some messages indicting your software detects 0 rpm it would be a logical and cheap thing to try.
