The fan on my Asus EAH4650 is really slow on startup and is noisy, then speeds up and the noise goes away.
The sound it makes is a mechanical noise, and it sounds like the motor is trying to spin quickly, but it can't.
Also, this only happens on startup. Once the computer is fully loaded (or a little bit after), the sound goes away. If we restart the computer, or turn it off, then turn it back on again soon after, it doesn't make the noise.
So, we think that it has something to do with the temperature sensor, where it can't detect the temperature accurately, and makes it seem like the temperature is cooler than it actually is, making the fan spin slower. Then, then it picks up the actual temperature, it spins faster until there's no sound.
Any help on how to fix this problem would be appreciated!
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

It will have nothing to do with any temperature sensor that's for sure. If the card is new then get a replacement under warranty, if not you may be able to replace the fan yourself with a pattern part.
I am presuming you have checked, by removing and inspecting the card, that no foriegn object has stuck on/in the fan blades (a piece of sticky tape etc, seen it happen). Again with the card removed check the torque required to move the fan blade from cold (place it in your refridgerator for an hour or so) and see it if frees up after turning.

Great! Glad to hear it.
I just want to tell you guys that it works fine now, after tinkering around with the fan control.
While I admit that the hardware will eventually fail, it may in fact remain in the same condition or a similar condition for a very long time.
Further, failure of the fan is only "catastrophic" if the user allows it to be. Personally, if one of my fans failed, I would notice that take the appropriated precautions. I have stated repeatedly that the fan should be monitored if allowed to operate in this condition.
Also, I do not see this as a safety issue. In the event the fan should fail, causing the card to overheat, it is likely the computer will shutdown with a BSOD long before the card starts on fire, and I fail to see what other safety issues could be present here.
As far as misinformation goes, I never said that the card would never fail, I simply said that if it continues to spin up to full speed, then it is not something that needs to be worried about.
As far as it being an opinion, obviously its an opinion. It is what I would do in that situation. Yours is what you would do in that situation. Your answer is different than mine, and neither are necessarily correct or incorrect. Keep in mind that I have not marked YOUR answer as unhelpful, and do not plan to as your opinion is indeed helpful.
And finally, as it appears that the card in under warranty, recall that I do recommend doing an RMA.
Certainly 'worry' is not the right word, but do be CONCERNED, ignore it at your peril. As with all electromechanical devices it will get worse, NEVER stay the same OR get better!!
Do you really want to risk a (possible) catastrophic failure of your computer (not just the card) because you chose to ignore the fault it has right now? What if it slows/fails WHILST your 'stressing' (using) the card? You will not know it has failed until a new 'symptom' (bang!) appears. I have seen a faulty card take out (irreparably damage) a motherboard more than once!
I do not understand some peoples attitude of 'don't worry about it'!
I guess that is the difference between an engineer and an ostrich lol.
Really, you've never seen any hardware with a minor problem remain in the same condition? I've seen it all the time. Hardware with irritating but not necessarily fatal problem never die. I maintain that as long as it is not an issue, it can be cautiously ignored. I say cautiously because I assume that the asker will pay attention and notice if the condition of the fan changes.
Also, voting answers unhelpful should not be used for a difference of opinion. Just because my answer does not agree with yours does not mean that it is unhelpful.
I would like to further add on my colleagues comment. I am sorry you feel giving an unhelpful answer was inappropriate but I stand by it!
We do not have 'a difference of opinion' I stated facts, a system will always flow to entropy.
NO I have never seen a piece of hardware 'remain in the same condition', it is an impossibility, a system will always flow towards entropy, i.e. it WILL degenerate!
I state again, it will ' NEVER stay the same OR get better!! That is fact not opinion.
You may well believe (and have observed) that a component with a 'minor...irritating' problem will 'never die' only because YOU have not observed it for enough time.
I stated a fact, the user risks 'a (possible) catastrophic failure' AND have observed such.
The only possible reasons (but not excuses) for ignoring such clear faults would be either financial or laziness.
I voted the answer unhelpful as it clearly gives incorrect advice, is an opinion ('I really wouldn't worry about it'), could lead the poster to further, heavy, financial loss, should the fault get worse (and it will), and is not addressing a possible safety issue!
