Can changing Fan speed break the GPU fan?

[woifx5]

Hey guys 2 questions

1. Can changing my fan speed for my GPU to prevent it from heating break my GPU Fan or my Video card itself?

2. If my GPU fan does break, Are the GPU gans REPLACABLE?

Thank you.!

1)If you slow it down enough and run it hard enough, it could potentially burn up. If you run it at 100% for too long it could reduce the life of the fan.

2) It probably could be, but you'd likely want to RMA it.

1. Yes, you could change your fan speed (at least in all the GPUs i known) and increase the speed to lower heat, but usually that's already programmed on the GPU, when the heat rises the fan speed up. If you are making this question i'm almost sure that in your case is better dont mess with GPU fan speeds.

2. Depends on the board, outside garantee some have fans that could be replaced with common fans (often 8cm ones) other have non-stock fans that makes almost imposible to replace them, but usually what you could do is replace all the GPU heatsink with a non stock one that bring his own fans or allow stock ones.

I am only running the fan at 60-70 percent on high temp's is taht ok?

1. If you turn your fan speed down too far, it may not provide adequate cooling for your GPU. This won't damage it outright, but exposure to high levels of heat for extended periods of time will shorten the lifespan of the GPU ASIC and the GPU VRMs. Most fans use brushless motors so running the fan at full speed or adjusting the speed will not damage or wear down the fan itself; the bearing(s) require lubricating after a while though, nothing some WD40 won't fix.

2. Yes. Most GPU fans connect to the GPU via a standard 2 or 3 pin fan connector. Replacements are easily found, but compatibility can be an issue. That said, I've never heard of a GPU fan breaking.

60-70% is usually high-very high for most of the Gpu fan, for example a lot of them i didn't see them running over 50% to keep the cards cool (70º-75º) while running Gpu intensive games if you get high temps at 70% i tihnk its not very normal (but depends on the card, older cards for example are usually a lot hotter)

What are the Gpu you are using, the temps you are getting at that speeds, the programs you get the temps, i think that with more data we could help more.

I usually get 30 degrees on idle, And I get 70 dergrees on intense games such as Bf3 and SR4.
What fan speed should I run it on?
Oh and I am on a GTX 560 TI EVGA

 

[juanrdp]

Those are good temps if you get them with default fan speeds, 70º on intense GPU games aren't hight at all (are in the normal range), with those temps i wouldn't change fan speeds and let them throtle themselves.

 

[woifx5]

70 degrees on 60 percent fan speed..

 

[woifx5]

So I let it go on normal fan speed (default) and its 75 degrees while playing SR4 is that ok?

That's fine. Automatic fan speed is fine in almost all cases.

It's perfect and in the normal range of temps.

I would left normal fan speed and left the Gpu choose the speed by the temp, you would lower the noise of the fan by a huge amount, increase the lifespan of the fans and 75ºC max are good for a card.

1. As far as i know, the fan will not shatter under maximum speed because it is meant to take double the rpm's the motor can reach before shattering. However, most fans will eventually burn out if you have them running at 100% for too long, unless it is actually moving heat, because running it at 100% all the time will cool it down to the point where it will actually start making the magnetic coils inside brittle from just being too cold, therefore damaging them and reducing electricity flow through them.
2. It highly depends on the type of cooler that was previously used and the type of board...for example, the silent edition of an ATI Radeon HD 5450 uses only a heatsink, so therefore, it is much harder to replace it, let alone find the part. The ATI Radeon HD 4850, however, uses a fan AND heatsink, so there is a much wider variety of cooling systems to install on this video card, therefore making for easier replacement cooling, and possibly cheaper in some cases. I know the harder-to-replace example doesn't use a fan, but IT'S A COOLING SYSTEM, lawl.

Overall, you should be able to crank the fan up to the speed needed to properly compensate the temperature. If you set the fan up right, it will have the longest lifespan, because the fan will be moving a lot of heat, as well as some of that heat will leak into the motor and keep the motor at a normal temperature, which ALSO gives the fan the best performance. However, over time your fan will usually degrade...if it takes any more than 52% to reduce your temperature below 70 degrees celsius, then you need a new fan soon.
