Gigabyte Brix Pro Review – GB-BXi7-4770R

Jump To:

Temperature, Power and Noise

If the Gigabyte Brix Pro was to have an Achilles’ Heel it would have to be the heat generated from the Intel Core i7-4770R processor. We aren’t sure where to start, so we are just going to dive in head first as we’ve had many discussions with Intel and Gigabyte about the thermal temperatures we observed on the Brix Pro. For starters the Intel Core i7-4770R is rated to be a 65W Max TDP processor according to Intel. Thermal Design Power (TDP) represents the near maximum power a product can draw for a thermally significant period while running commercially available software. We have been able to get the Gigabyte Brix Pro over 65W TDP by launching apps that use both the GPU and CPU according to the ‘CPU Total TDP’ in Intel XTU.


For example we were running a couple apps and closed one to open another and the CPU Total TDP was at 73 Watts when doing this task. This is 12% over the rated max TDP and was with just a CPU and GPU intensive application being opened and closed. We have been told that if you fully stress everything on this system that you can easily hit a TDP of 85 Watts. Why is this an issue? From what we can tell Intel doesn’t put the CPU and GPU at 100% load to get their ‘typical’ max TDP number. Gigabyte designed their CPU cooler for a 65W TDP processor and therein lies the issue. What issue?


We’d be talking about the 56C idle temperatures….


And the fact that you are running 100C with CPU throttling after seconds of running a CPU intensive application. In the example above we fired up Cinebench and it the fan ramped up to a scream, but couldn’t keep the processor from a 50% throttle.  Intel XTU said that it was throttling and so do other applications. There is no easy fix for this, but Gigabyte said that they are working on a new BIOS that will improve throttling issues in certain conditions and that we could disable turbo. Yes, Gigabyte actually told us to go into the BIOS menu and under the Advanced CPU Configuration that we should disable Turbo Mode. They claim that will drastically reduce temperatures, but who wants to disable features on a flagship processor like the 4770R?


Here is a quick look at what happens when you run Prime 95 on the Gigabyte Brix Pro. Notice that all three clock speed monitoring tools are reporting different clock speeds due to how fast the processors is switching the clock speeds. It is tough to tell you about how loud this is, so we tried to make a video clip to show you.

We used a Rode Video Mic Pro that was positioned one foot away from the Gigabyte Brix Pro and recorded the sound for you to hear. At an idle the system used ~10.6 Watts of power, had a CPU temp of 56C and a noise level of ~38.9dB. When gaming we found the power peaked at ~81 Watts, the temperature was pegged at 100C and the noise level was ~52.3dB. We also included the results for the Intel NUC D54250WYK so you know how other tiny SFF DIY PC kits sound. As you can hear the pitch of the fans in the Gigabyte Brix Pro make it tough to ignore at both idle and load.

At the end of the day we have to conclude that the CPU cooler in the Gigabyte Brix Pro isn’t enough for the Intel Core i7-4770R processor, which is a real shame. This is a really a great system and form factor, but sometimes you can push the envelope too far.

    I was finding a review for this, great one

  • Kevin Hess

    complete junk

    • Todd Oxenford

      “Complete junk.”

      I think not! I use this as my Plex Media Server and it does a fine job transcoding multiple streams at once with no issues.

      • vampyren

        Good to hear 😀
        I have a NUC with i5-4250U and it sucks, cant even play the movies locally with Plex. So i was looking at this. Nice to hear your happy with it. Sure its expensive but i watch movies allot and love Plex for keeping a nice library 😀

        • Todd Oxenford

          I think you really need an i7 for transcoding. As I said, I have multiple streams running locally and remotely and have no issues..although, it does get loud, so I put the everything inside a cabinet and am using a Logitech Harmony Hub, controlling everything with an old iPad.

          It’s worth the upgrade. I also bought one for my son who needed an new PC, and he mounted it on the back of his LED TV.

    Hey Legitreviews/Nathan. Thanks for a good review! 🙂
    This review was very interresting to read but it would have been even better if you could have demonstrated game performance with different RAM speeds, and also if you could have shown more reference systems and a few more games because right now its a bit hard to evaluate how much better this performs compared to say a desktop Intel HD 4600, or where it would place compared to a GTX650/750.
    Btw, I really agree with you they should have made it one/half inch taller for better cooling. I actually would have preffered a overdimensioned cooler by big margin rather than this underdimensioned one that encourages ppl to underclock their new system.

    PS. Maybe the reason the TDP went skyhigh was because the memory was much faster than i7-4570R’s max specced RAM-speed (=1600mhz). Anyway still a really interresting aspect of this Brix Pro and before reading this review I didnt knew it would accept that kind of “OC”. I hope gaming-performance scales linearly with RAM speed.

    what is this good for?

    Kind regards

    Is it possible to have both SSD and a 2.5 HDD at the same time?

    • Simon

      Yes, mSATA + 2.5″ SATA HDD (9mm)

  • Sin Sentido Comun

    WOuld be nice to test audio software, I am very interested but noise can an issue, at the same time audio apps doesn’t consume much video power (or not one at all) so it might not push the GPU too much,

    • Todd Oxenford

      I run Foobar for some ripped SACD’s and it works and sounds great going through Dolby Digital 5.1.

    Any chance you have a Kinect for Windows sensor and are willing to try out the system compared to something like a GTX 680? If that thing can get solid 30fps in 3d mapping mode, it will be THE robotics controller platform everyone is using.

    • legitreviews

      I do not have the Kinect for windows sensor and I know that has different features than the normal Xbox 360 Connect that are all over. Anyway to use the Xbox version?

      • basroil

        There’s nothing technically stopping you if you have the USB adapter, though the results might get wonky. Kinect Fusion doesn’t inherently use any of the Kinect for Windows features unless you enable them, so as long as you don’t try texture mapping or near mode it should work. Just remember to up the resolution (voxel density) until you hit just under 2gb vram use.

        • Peter

          Did you have the time to try Brix with the kinect sensor?

        • basroil

          Still no budget for brix, perhaps in another 6mo (though 960m version would be out by then)

    Why do you mention BIOS repeatedly in the review? This is a UEFI implemntation, not a BIOS. But you call it “UEFI BIOS” to really get things wrong. Why?

    • Internet

      Perhaps you can merge this in with the previous note?

      Watts dissipated in use isn’t “TDP” – TDP is Thermal Design Power. You can’t “hit a TDP of 85w” during use; the design power is still 65W. You are instead generating 85w in the form of heat, but not generating a “TDP.”

      I won’t go in depth about the editorial problems with this piece… nearly every page has some flaw, including missing half of a paragraph on page 3.

      Also: Your KeyShot 4.3 is unregistered, and not for commerical use. But the purpose of these reviews is ad revenue, isn’t it?

      I don’t really get what’s legit about repeated misuse of terminology.
      This article is quite poorly written and I do not believe the author possesses
      the knowledge necessary to write about these topics.
