Internal vs Rear Exhaust GPU Coolers

2014-12-28
gaming gear no not game gear gaming gear like the stuff you need for gaming can be confusing to buy with all the marketing fluff that gets thrown at gamers in fact soon we'll be helping gamers narrow down their chair choices but today something a little bit more traditional Linus tech tipsy gaming graphics card shopping ensure swift victory with Corsairs highly responsive lightweight gaming mouse the Sabre RGB click now to learn more now often the most obvious difference between one video card and another is the cooler and this can have a tangible impact on the noise from your PC the lifespan of your card and even the performance of your gaming rig thanks to the way that modern graphics cards turbo up their speeds when they're running nice and cool and throttle them back down when they're overheating now there are marketing names for the coolers used by the various card makers windforce vapor x direct to you etc etc and some of them are bound to be a little bit better or worse than others but today's video is going to tackle this from a broader perspective how does the OEM style rear exhaust blower design that you'll find on a reference video card one with a cooler design by AMD or Nvidia and then simply produced and rebranded by the manufacturer compared to the open air designs that are typical of a non reference video card where they blow the air kind of around in the case versus blowing it out the rear panel so let's walk you guys through the tests we'll be using we wanted to examine this from the perspective not necessarily of the most extreme PC enthusiast but rather a more typical PC gamer so instead of using a corsair 900 d case we went with a bit phoenix shadow a mid tower chassis with decent but decidedly unexceptional cooling with 120 millimeter fans at the front and at the rear on the inside we didn't do any special cable management we installed a quad core Core i7 non overclocked on a passively cooled asus motherboard and we installed our power supply fans down so we didn't take its own fresh air and exhaust it directly out the back without affecting the other components in our test for our cards we chose a geforce gtx 780 Ti win force from gigabyte and a reference gtx 780 Ti that we've got directly from Nvidia we chose these cards because as a high-end card the 780 Ti generates a fair bit of heat giving us a worst case scenario where the difference in the results will actually be measurable and because our 780ti wind force uses the same PCB design as our reference card eliminating board efficiency as a variable we also overclocked our reference card to put it roughly in line with the rated clock speeds of the wind force card now we tested each configuration at idle and under load with Crysis 3 no unrealistic synthetic benchmarks here and took temperature readings with our K type probe at the front intake rear exhaust and inside the case near the stock CPU cooler then we also took CPU GPU motherboard and motherboard vrm temperatures with a Seuss's AI suite monitoring software and MSI Afterburner now normally when we benchmark graphics cards we do it on an open-air test bench for the ease of swapping them in and out but it appears that we may need to re-evaluate this practice at some point in the future because while we did still observe lower temperatures and therefore marginally higher boost clocks on our open-air graphics card just like we do on an open bench the internal temperature of our case and therefore the temperature of every other component inside went up significantly we're talking an increase in the neighborhood of about 5 degrees and on top of all this the noise advantage that we normally observe with open air coolers was nowhere to be found our wind force card was actually noticeably louder while the entire system was noticeably louder with our wind force card then with our reference card so there you go non-reference cooler smite let your GPU run a little bit cooler but the rest of your system will run hotter and possibly even louder unless you take the appropriate precautions because remember this test scenario was designed to show maybe not quite the worst but a very bad case scenario a mid-range GPU with a lower TDP will not affect your case temperatures to nearly the same degree degree like degrees of temperature sorry and adding more cooling fans or using a better ventilated case like a fractal arc series Corsair graphite series or cooler master half series would help as well so the real point here is make sure that you use open air coolers responsibly and work to keep the rest of your case temperatures down let us know in the comments if you thought this was interesting and if you'd like to see us tackle this topic again with maybe a different overall system configuration and speaking of overall different system configurations how about ones that are super hyper compact for free yes ok not everyone gets one for free but this is the Intel not d50 425 0 w ykh wow that is a bit of a tongue twister and if you're not familiar with the nook these things are freaking cool there are little tiny pcs like so small you can fit them in your hand but they're actually fully featured pcs so you can install soda memory in them they've got Intel onboard graphics they've got Intel CPUs they've got support for USB 3 they've got support for HDMI and DisplayPort out this particular one has mini DP and mini HDMI out for up to dual displays and supports Gigabit LAN and finally also has you know your built-in sort of sound and all that stuff so basically they're useful for a ton of different things if you just need a little tiny PC for basic light use it'll do for that if you need a media center PC this kind of thing makes a ton of sense compared to building up a full-sized tower next to your TV when you can just hide it in the back or hide it in a corner or really hide it wherever you want because the thing is actually passively cooled will be completely silent wherever you run it to the other thing that they can be really great for it has a stream PC ok yes this is very similar to media PC because it would also be hooked up on your TV but because of the Intel onboard graphics built in h.264 decoder if you have a gaming PC somewhere else in your house you'll be able to decode using steam in-home streaming and run your games with that really very little latency completely separately without building up a separate gaming machine so they're super cool they're actually surprisingly affordable and we are giving one away
