XFX HD7950 gettinq too hot! please help guys

hello,
i have build my first pc, but the GPU temperatures are getting too hot while gaming.
i have 2 HD7950's and they are close together(matx), i also get high temps with one GPU.
2 GPU: 38-42C when idle, 88-99C when gaming(under load)
1 GPU: 42C when. idle, 85C when gaming(under load)
i have 3 fans installed, one front 120mm(inhale) one side 120mm(inhale) one back 80mm(exhaust)
-i even tried with the side removed, i still get the same temps if not higher.
-i also tried wirh the side removed and one big housefan blowing air at the fans! it got 80C while gaming with 1GPU.
-i also tried both gpus at once= same stats..
it is really bothering me because i have a new matx motherboard so i cant buy a new case and big mobo, maybe u can return the mobo...
please help me guys i appreceate it
sorry for my bad english.

  1. Are the case fans stock fans (i.e. came with the case) or aftermarket?

    the exhaust fan is stock(aerocool)
    the side and front fans are aftermarket and threy are 60-80cfm i believe.


    oops... i suddenly pressed that best answer button now it says its a solved thread....
  3. I unselected it :) Do you know the brand/model of your front/side fans? And does your case only support an 80mm rear fan or can its size be increased?

    Also, could you check your CPU temps using realtemp when at idle and at full load? And also what is cooling your CPU? (This is just to get a general idea of the airflow in your case, which we could also use the make/model of :) )

    thank you!
    the rear fan slot is just 80mm, i have these aftermarket fans:
    -spire fan blower 120, 1500rpm, 65cfm, side)
    -Arctic Cooling ARCTIC F12 , 1300rpm, 73cfm , front)
    the cpu cooler is just an stock intel cooler, the cpu temps under load are max 58C so i believe this is fine.
    thanks for your help so far! appreceate it!

    No problem :) If you post on a forum, you want answers right? :)

    Anyway back to the problem, could you by any chance take a pic of the inside of your case for me? Just so I can have a look at the setup :) (Don't worry if it's messy lol)
  7. Check the fans. Are they clear of dust or any obstruction.
    And the gpu has more potential to withstand high temperatures. So 80-90'c is not very high while gaming.

    here is a picture which should give u an idea


  9. 2 more :D
  10. I thought you had 2 HD7950s? There is only 1 in these pictures
  11. Yes, i have 2 but i have only plugged one in right now because it gets too hot while gaming and i wanted to play a game a couple hours ago.
  12. ok could you put your 2nd one back in the machine for me just so I can see how close it actually is to the other card?

    (And take a pic obv)
  13. they get this close to eachother, and also a crossfire bridge ofcourse
  14. That does seem pretty close tbh, is 120mm the biggest fan available on the side panel? and are there any empty fan placements in the case?
  15. There is a spot for another 120mm fan just slightly above the sidefan that is installed. But im scared that this wont help because i pointed one bigass housefan on the GPU's and the temps just changed by 2-4degrees.

    Could you use a lower PCI-E slot for the 2nd GPU? Or is that the furthest you can get it from the 1st GPU?
  17. harry_r_s said:

    And the gpu has more potential to withstand high temperatures. So 80-90'c is not very high while gaming.


    Locopatre, make sure to do this. Dust in the GPU Heatsink will cause rising temperatures, cleaning them out may get your temps down by around 5 degrees, maybe more
  18. I can use the lower, but the lowest is not an PCIe 3.0 x16, it just a PCI x4 slot or something like that...
    But the problem is not the two cars i think, because even with 1 gpu inside it gets hot...

    Edit: The gpu's look really clean... almost no dust on them
    again thanks for your help
  19. Could you post one more pic where we can see the PCI-E slots under the GPU? Just for reference :)

    How hot is the GPU getting when it's not running in crossfire?

  20. I posted it in the first post: 42C when. idle, 85C when gaming(under load)

    Nono the fans are brandnew, but i dont like the idea of having a system running so hot... i wanna be able to sit back and relax while my pc is on haha... and what do you think about the crossfire?... 98c
  22. Loco try using the bottom PCI-E slot, then check temps again. The extra clearance should give you some lower temps. If the bottom slot is a PCI-E 3.0 x4 slot, you shouldn't experience any performance loss as this gives the same speeds as a PCI-e 2.0 x8 slot

    bro, i just first get good temps with one GPU, then my system is ready to use 2 GPU's...
    So how can i lower the temps of my gpu...? because it is not airflow... this is strange to me

    85c when under load is ok. Your system doesn't have great airflow, I would probably recommend getting some Corsair AF120 Performance edition fans if you want better airflow in your system, maybe a noctua NF-R8 for the rear. For now though, just try the 2nd GPU in the lowest slot, just to see what the temps are like.
  25. Also, check in your BIOS whether or not you can increase the RPM of your case fans, they may get louder though

    Why do u recomment these fans?
    The corsair is only 40cfm, and the noctua 31cfm, isnt that low? the fans i boughd it says 70cfm? and is like 8 times cheaper. I will try to put one gpu in the lowest pci slot and see what happends...

    I will check bios now.

    the fans may produce 70cfm, however the design of the blades may mean that a lot of that air is wasted around the fan, rather than being pushed into/pulled from the case

    In bios the fans are set to FULL ON... oh i understand that is true. but what do you think about the big fan i pointed at the pc? and still high temps? the GPU was 82degrees under load(1GPU in the pc)... wasnt that enough cooling? or do i need a big 10meter turbine to cool my pc

    I'm still not convinced that your airflow is great. In the BIOS it should give your motherboard temps, they should give us a more clear indicator of your airflow, also try downloading SpeedFan and increasing your GPU fan speeds, see if that helps
  30. Why is the GPU usage sometimes get high and low again?(and why are temps dancing) i just have internet opened...? and no youtube or something too.
    It just got to 56C when i opened a video on youtube.... this is crazy
  31. I had two XFX 7950 DD and the cooler was very bad, even with 1 installed. The GPU got up to 105C and the heat on the rear of the PCB was 95C!! The cooler simply could not remove the heat from the GPU well enough. Even with the fans on 100%, the temps rose very quickly. Even down clocked to 700MHz, they were hot.
    In crossfire, it was even worse, the top card sucked in the 95C heat from the PCB of the bottom card. I tried making a Perspex separator and had a 120mm fan at the end of the cards blowing directly across them, still crap.
    So I sent them back and got two HIS ICEq, which were great, max temps 75-80C when o/c and expelled all heat out of the case.
    I've had GTX670, GTX680, XFX 7950, HIS 7950, Sapphire R9-290 and the XFX were by far the worse, almost unusable.

    oh wow... well my GPU's are second hand... Some people get better temperatures with the XFX cards i believe,
    So the matx is fine that i have?... should i sell both my cards and buy just ONE card with less performance, but fine temperatures? maybe a r9-290...?
    I love the performance of the CF 7950's...
  33. last gut I helped with xfx cards I read the reviews at newegg on his and it looked like there were two types of reviews the ones that there cards ran on the cool side and the ones that ran hot [??] needless to say his card also fell into the hot side of things
  34. It would be better if you had one great card as opposed to 2 good cards, but I've heard of a lot of people having problems with r9-290 and 290x cards at 1920x1080 resolutions when running direct x11. You might be better off getting a GTX 780 if you can get the funds together

    the GTX 780... that would be adding more money to get a part with less performance... that sucks. Are there no crazy ways to cool the HD7950's..? like a big cooler inside the case..?
  37. ya but them 2 big cards stacked on top of each other there going to get hot
  38. what you is need better ventilation..... check for dust and dirt in the fans and its filters if you have any.. what you need is active input airflow and passive output airflow... use aftermarket pressure optimized fans.. gpu temps upto 90c is approved my AMD .... above that would be risky but i am defenite that better input airflow will fix the issue

    then what do u reccomend me todo to have an active airflow?
    i have 4 fan slots, one front, two sides, one back. and the gpu's are blowing air to the ground... so should the side be removing air from the case?

    should i return my matx mobo and get an new case and an atx mobo? will this give low temperatures?
  40. Best answer
    I don't see it. it just looks like you got hot running cards I mean you said you had a house fan blowing straight on them just to get them to 80c seems like a lot of wind pushing on them that's about direct air flow as it gets .. funny thing is I done this with my computer to see how much cooler it would run and the temps stayed the same but there fans would spin down to maintain the same running temp.. with out house fan 64c @ 34% fan speed with house fan 64c @ 31% fan speed so it was like this card is running 64c at full load no mater how much air I pushed to it

    hmm interesting, so basically it doesnt matter how much air is pushed to the cards.. so what are the factors for a gpu to lower the temperature... this is wierd, so what about airflow...? what is best way to cool it hmmm
  42. well I did not see you say it was causing crashes or shut downs just run them till they die or your ready to replace them also for all you know the temp sensor is off all anybody got is what it shows I said mine shows 64C heck for all I know it could be 80c or 45c it real life I just go with what gpu-z shows me . is it true ? don't know ,but all I know is it works and I will run it till it dies it may be tonight or 4 years from now as for me them are big power hungry cards and I would expect them to be on the hot side anyway..

    well that is one ghetto way to put it, haha. i wanna keep these cards for like 5 years man i dont wanna keep investing in a pc, i wanna be able to give this crossfire build to my grankids.
    but srsly tough, i have 6 days that i can return this mobo... should i return it and get a bigger mobo and a bigass case? will this help witth the temps? will i get 70C? 80? or still 90C?

    i feel it gettin hot tho, i can flip the side fan to exhaust and warm my feet with in the summer. or take it to the living room to warm up the room or boil water
  44. that is all your call you can only do what you feel is right as I said my card runs cooler but it pushes a lot of hot air and if you put your finger on the copper pipe you will pull it back quick and it heats up this room and its just a 7850 but with them cards you got one should do all you need with out x-fire pull one out and give it some breathing room and box the other for a back up
  45. junkeymonkey said:


    Yeah, he also posted that here on this thread. Im really wondering if its worth it to get a bigger mobo and new case..

    AND ALSO, shouldn't the side fans be exhaust? because these GPU's push all the hot air at the bottom of the case and it will just make small circles there...?
  46. turn them over and see cant hurt to try
  47. I was thinking that weather its a atx or m-atx board the slots should be the same so the cards won't get any more room between each outer if you go with a larger case all you gain is air space .. as far as flow the fan in front pulls air in and the rear sucks it out . use to the psu fan pulled a lot of hot air out and hot air rises but todays psu got the fan control to where like mine it don't run unless its getting hot its self so I got like 4 inches of case space that don't get much air flow cause the rear fan is just above mid way

    On a atx board there are more pci slots so more space... like this


    And now it will be like (matx):

    yes i have the setup u are saying, the top half of my pc is not hot, its max getting 50degrees, so thats fine... And ONLY the gpu gets hot. it was on 78C with some program and i touched the GPU... but only the back of the GPU is hot, the metal(heatsink) was actually cold!
    is this a thermal paste problem?
