Temperature & Noise Testing

Temperatures are important to enthusiasts and gamers, so we took a bit of time and did some temperature testing on the Gigabyte Radeon R9 270X OC video card.

Gigabyte Radeon R9 270X OC 2GB Idle Temperature:


The Gigabyte Radeon R9 270X OC was found to idle at 24C with the fan running at right around 1600 RPMs. It should be noted that the ambient room temperature was 22.0C (72F).

Gigabyte Radeon R9 270X OC 2GB Gaming Temperature:


The Gigabyte Radeon R9 270X OC topped out at just 51C with the fans running at 2200 RPMs when gaming on it for an extended period of time!


The Gigabyte Radeon R9 270X OC was one of the coolest running cards that we have seen in some time. The idle temperatures was near the lowest that we have seen and the gaming load temperature was the lowest on our current test system. The temperatures on this card on our open air test bench are impressive, so what about the noise?

Sound Testing

To test sound levels we use an Extech sound level meter with ±1.5dB accuracy that meets Type 2 standards. This meter ranges from 35dB to 90dB on the low measurement range, which is perfect for us as our test room usually averages around 36dB. We measure the sound level two inches above the corner of the motherboard with ‘A’ frequency weighting. The microphone wind cover is used to make sure no wind is blowing across the microphone, which would seriously throw off the data.


The Gigabyte Radeon R9 270X has the fans spinning at 1600 RPM at idle and we hit 2200 RPM when gaming, so we knew right from the start that this card was going to be average.  Once we put it in our chart we found that the sound levels put it near the middle of the pack. The cards noise isn’t bad at all, but will be able to hear it when gaming.

    That is a LIE.I have a i5 2500 @ 3.3 ghz OC 4.0 ghz at 1920×1080 ULTRA settings and 70fps average.

    Just an idea… when showing so many cards on a benchmark, it would be nice if you were to highlight the card that’s being reviewed so we don’t have to play a game trying to find it every time we change page. Thanks.

    20+* same graphics card.

    Ironic how I just pushed the memory clock with 1550 mhz, you guys didn’t even touch the power control settings, I pushed it up to +2.

      Looks like you got a good OC’ing card! No two cards are identical and the memory on our sample didn’t like being overclocked. It happens.

        Sorry about that, just realised my model number is different, it’s actually a : (No idea what the GA stands for.)

        • blah

          GA simply means game, which means that your card came with BF4.

  • basroil

    Higher idle power than the 7870 it replaces? That’s not cool.

    • Indeed. I read about it everywhere. It’s the main downpoint for this “rebranding”
