Overheating cards

Hi, I recently bought a new graphics card because my old one was having artifacts at stock settings and even when my fan was spinning at 100% (I could hear it) the thing was getting over 80 degrees C.

So imagine my surprise when my new graphics card is doing the same thing. The first card was a sparkle GTS 250 from NVIDIA and the second card is a Asus Cucore Radeon HD5770. Both cards completely refused to overclock too, but it is more understandable for the GTS 250 than the HD5770. And my Radeon is currently spinning at 100% and at idle is 42 degrees C. That's 157mhz core and 300mhz memory.

I tried to underclock the GTS 250 to get the artifacts to go away but, while it worked, my temperature alarm was still going off and the card, according to Real Temp and furmark, was still getting higher temps then it should.

I want to know how to avoid this situation when I return both cards, RMA for the GTS 250 and 30 day warranty for the HD5770. What companies are know for excellent build quality? I am new to the computer scene and don't know who's what here.

More about overheating cards
  1. Well, the ambient temperature/high humidity may have something to do with it, especially the humidity, but I wouldn't expect it to overheat the card(s). For example, if I have my window AC unit off in the room where my computer is while it is warm out, my HD 5830 will run in the mid to upper 50's with the fan on auto speed (with the AC on it usually holds in the mid 40's).
  2. One thing I forgot to mention, my ambient room temperature is 85 degrees F with some humidity, ie what you get with a swamp cooler.
  3. 42C isn't bad at all for the 5770. What kind of temps is it pulling down while the fan is on auto or at a lower fixed RPM? On a side note, what kind of case do you have? Fan set up?
  4. I'm thinking if you can somehow put a new fan near the graphics card or redirect another, it may help your temps out considerably. Is there another card in your system that sits below the graphics cards, i.e. where the fan on the GPU would blow directly onto it? If so, may be a relocation is in order.
  5. I said mild humidity. I live in a desert, the only humidity I experience is from my swamp cooler with is located just about as far from my computer is you can get in my house.
  6. I have the V9 gaming case from Thermaltake, it has a 200mm fan on the door and another one on the top. It has a 120mm fan pointing out away from the CPU and another one by the hard drives.

    And the 42 was with 100% fan RPM. Without it flirts with 50-60 degrees.
  7. Aaah ok, I misread it- my bad. Maybe someone else can chime in here with some further recommendations, especially someone with the same/similar case.
  8. Nope, i have integrated sound and network, no tv tuner, and no extra graphics card. Just the one 5770.

    I've heard that the build quality of the Asus Cucore is very poor, dimples and waves on the copper surface, and I just want to avoid that.

    Is there something that I need to change in the bios?
  9. And the overheating is accompanied by instability. I overclocked the card from 850 core to 880 core with no changes to the memory and it crashed Crysis and it's benchmark tests, which is the only reason I would overclock at all, every other game I own is comparatively easy to render.
  10. I wouldn't think so about adjusting anything in the BIOS. Typically you'll get the most control out of a graphics card with the software included, i.e. Catalyst Control Center.
  11. I'm looking at Catalyst and there is no option for voltages. And I still need to deal with the heat. Any good coolers that you would recommend?
  12. Hi,

    if the psu is dying, it could be the one causing your artefacts on old and new gpu.

  13. brad is likely correct. for the temps your saying they simply shouldn't be that high even with ambient 85f air. your psu is likely on its last leg and feeding your components dirty voltages..... get a multimeter and test your psu

  14. The PSU is brand new, I bought it last december.
  15. I've had this problem before and it was a fault with the motherboard, no matter what PSU was used or what graphics card was put in the system, the card got cooked, 80-90 degress c on idle, if fan was put up to 100% you might get that down to 70-80, but then if you put any stress on it, the cards could go up past 100 degrees with 100% fan.
  16. To be more specific, both nVidia (8800GT GTX275 GTX295 and ATI (5970 4870) cards were used, a 1000w Enermax PSU was used, a 850w OCZ and a 600w PSU i can't remmber what brand it was.
