Graphics Card Overheat

Hello all.

My Radeon HD 4890 has been working perfectly fine for a while, but just yesterday, it started to overheat. Usually it would heat up quite a bit, but this time it actually crashed the computer from overheating. I'm using two Radeon HD 4890s in crossfire mode so I thought it was a lack of power that was causing the problem. In order to find out I took out the functional card and only used the overheating Radeon HD 4890 and it was still overheating. Any ideas on what else may be causing the problem?

Thank you.

  1. Check the cooler on the card for dust and lint!
  2. Yes, always check to see if their is dust clogged in the fan if you think it's overheating.

    How long have you had the card(s)?
  3. it could be dust, so that is the first thing you want to check. if you clean it out and it still overheats it is probably just age is finally getting to the card and it will be time for an upgrade
  4. It's been less than 2 years and I use a dusk removal spray pretty frequently. I just noticed that the one that was functional is now also overheating. Just replaced the thermal compound too.

    Thank you for fast responses.
  5. My next suggestion was going to be replace the thermal compound but you've already done that.

    And no temp differences after that?
  6. My bad, I was replacing the thermal compound again. I thought it looked a bit smeared. So I took the entire thing apart and cleaned it all out and tried to put it back in. The problem now is that the fan won't even spin. I know the card still works cause its heating up and stuff. Anyone know how to make it work again? The fan is already plugged in and on boot up, the fan moves a little bit then comes to a stop.

    The problem with the other graphics card was that the fan wasn't plugged in, that was my fault.
  7. Try adjusting manual fan speed in the CCC.

    You shouldn't use the card if it has no fan.
  8. Yea, I'm not using it right now. The fan physically won't move so manual fan speed controllers do not really do anything. Still tried it anyways and nothing happens.
  9. It is possible that it's just dieing.
  10. Yea that's my guess. Should I invest in an aftermarket cooler?
  11. Alright! The fan is working again but it is seems much slower than before. You can almost see the fins individually unless you crank it up to 100% fan speed. For now, I think the card will be fine since the other graphics card is gonna have more load.
  12. I would suggest buying an aftermarket cooler.It shouldn't be to hard to find one for the 4890.
  13. Never mind, the stock cooler still isn't working properly. I guess I'll buy an aftermarket cooler.
  14. Do you have a budget for the new Cooler?

    Here's a really good cooler for your card..

    Here's some other coolers that should work for your 4890 but be sure to check the specifications to make sure it will.
  15. I was looking up what would be the best one to get and the Twin Turbo always popped up. It's a bit too pricey for me though. I was looking for something that would keep my graphics card at a reasonable temperature while gaming at high settings. I don't mind temperatures like 90 Celsius while gaming. Do you think something like the Arctic Cooling Accelero S1 Rev. 2 would do the job? Would it even fit the card?

    Here's a link to it:
  16. If there's any other cheap cooler I can buy, please tell me.

    Thank you.
  17. I don't see why this cooler won't fit.

    It says it fits the 4850.Is their a huge difference in size or location of the GPU on the 4890?
  18. I don't know if it's different from the 4850 or not.

    Here's my graphics card :

    So would you recommend me getting the item you linked?
  19. I would want to be sure.

    Why don't you create a different thread to find out what the best cooler would be.Make sure you tell them what your budget is,cause i'm sure a lot of them will suggest the $50 cooler.

    I'd say the best cooler thats the cheapest would be this one,the one you suggested.But i'm sure you can find something for cheaper.
  20. Alright thanks for all the help.
  21. Welcome

    What do you think your going to do?
  22. Probably make a new thread like you said or try to add some lubricant to the stock fan cause it looks like its a bit stiff.
  23. You should look up online what type of lubricant it takes.I'm thinking just putting some WD-40 on it won't make it any better.
  24. Alright. Putting on WD-40 was the original plan, but maybe I'll just get a cheap cooler. That sounds much easier.
