Solved Graphics Card fan is not working!

[kujvi]

My Brother has purchased 5 Saphire RX 480 8GB graphics cards specifically for mining purpose. They have two fans placed on them. Now one of the card's fan is not working properly. When we turn on system lights on all fans glow but one graphics card have problem. Its fan sometime run then stop and often they do not run at all.
That one graphics cards also heated up more fast then the others.

What should i do we are not hardware expert and computer technician are very expensive.

I don't think you'll find anyone here who can help you with this. However, since you are going to be making some money with the "mining", you could use some of that money to pay a local computer hardware expert to help you.

Like you said in this post (Bit coin Mining Sites uses PC secretly for Mining Hence Cause CPU temp), you'll probably overheat your computer from doing this. Using eight graphics cards in the same computer will probably totally fry your computer.

well said bro. Now i search cryptocurrency forum to ask this question. It is a real problem and i want solution.

In addition to your graphics cards running extremely hot, your CPU is going to operate at 100% all the time, generating extremely high temperatures.

You will need a super cooling system to keep from frying your computer. If you don't seriously upgrade your cooling system, your computer is not going to survive this. I suggest you do research into cooling systems which can handle extremely high temperatures in a computer.

so what do you say whether air cooling system is best or liquid cooling system.

 

[mrjimphelps]

A liquid cooling system would be much more effective than simply blowing air into the computer. A liquid cooling system actively removes the heat from the computer, whereas a fan is much more passive in heat removal. Therefore, the liquid cooling system will remove heat a lot more effectively than a fan.

Liquid cooling has the added advantage of not blowing dust into the computer; that will help a lot over time to keep the computer from overheating -- the liquid cooled computer will stay cool, while the fan cooled computer will get hotter and hotter over time because of the increasing amount of dust in the computer.

If a fan in 1 of 5 graphics cards is not working it seems highly likely that the card has a problem. It should be returned to the seller for repair or exchange. If this was a recent purchase this should be covered by warranty.

You will likely need better case cooling. Under normal conditions the standard case cooling would be adequate but with 5 graphics cards the situation is not normal. The graphics card fans will remove heat from the card but it still needs to be removed from the computer. These fans cannot do their job efficiently with a high case temperature. I can't help you with this.

so which liquid cooler is good and where i can check or compare them. Can you refer me any link or site?

Warranty period is gone, so i cannot return it to the seller.

Sorry, I'm not familiar with the various cooling systems.

Perhaps you can replace the fan on that card. See if you can remove the fan from the card; then get the part number, etc., on the fan, to try to purchase the same fan from Amazon, Ebay, etc. You should be able to replace the fan on the card. But if you can't, you need to get another card. If you don't, the card will burn up, and overheat the computer in the process.

okay

Well, this old tech can tell you exactly what to do!

I've had several graphics cards that I really like, except that the little cooling fans are really CHEAP and have a tendency to get noisy and even just lock up in time. And the OEM (replacement) fans are usually not easy to find.

I just take out the graphics card, remove the fan, and re-oil the main bearing, which is usually under a little stick-on label on the back of the fan. Don't remove the label, just poke a tiny little hole in it and inject a drop of high quality machine oil. A pocket oiler with a needle tip is ideal.

I have a needle point oiler that I've used, for years, just for the purpose of re-oiling fans, and I've re-oiled hundreds of them. Not only GPU cooling fans, but case fans, PSU fans, and CPU fans as well. Almost all small fans in computers can be cleaned, re-oiled and put back into service, with the only expense being a few minutes of your time.

In the few instances when the fan is totally frozen up, I just remove it and attach another small fan right over the GPU heatsink. When I can't use screws to mount the new fan, I've used HOT GLUE, to attach it.
( have a great picture of an added fan on top of a GPU heatsink, but this @#%^& forum software won't let me post it, from my computer )

Most things are Do'able if you just get creative.

Cheers Mate!

Well thanks for telling such an DIY tips. I will apply them.

Great information, TechnoMage!

Have you ever seen a case where a card got so hot that it melted the hot glue?
