0:00 recently we made a video investigating the usefulness of video card back plates
0:05 in a shocking surprise to No One the
0:09 thermal benefit was marginal if anything
0:13 at all so then when EVGA called us up
0:16 inviting us to check out their top secret IX technology that was going to
0:22 solve video card thermal issues we had to wonder I mean is this just another
0:27 case of gluing on more bloody fans and back plates or is it a worthwhile
0:43 Innovation the Phoenix oour is a full-sized minimalistically designed
0:48 keyboard complete with Cherry MX switches and a new white backlit variant
0:52 check it out at the link below what the crap is icx technology I
0:58 how do I even pronounce that I I6
1:02 I6 well whatever evga's marketing team
1:05 helpfully describes it as a new and more efficient way to cool with optimized
1:11 airf flow fin design which is a good start because an old and less efficient
1:15 way to cool with an unoptimized airflow fin design would raise a lot of
1:19 questions essentially what it boils down to is this rather than try to sell us a
1:25 revolutionary fan blade design or whatever it's more about data IX relies
1:32 on nine discrete thermal sensors to
1:36 dramatically expand the card's monitoring capabilities so in addition
1:41 to the GPU we now get readings for each
1:45 Bank of vram and the power delivery
1:48 modules the cooler can then take advantage of this sensor data to
1:53 intelligently cool the entire card as
1:56 needed to the point of independently controlling its two fans if let's say
2:02 the GPU temps would allow a normal card to spin down but the the rear portion of
2:07 the card was still hot pretty cool
2:10 concept and they've tacked on every other feature that they can think of as
2:14 well like the perforated heat SN fins low power fans for additional GPU power
2:20 budget really you guys and a back plate that EVGA says helps with cooling a
2:25 claim that seems to be in Vogue these days all of this of course culminating
2:29 in the Bold statement play longer overclock better so how do we test these
2:35 claims in our possession is a brand new EVGA GeForce GTX 1080 Super Clock 2 with
2:42 an all metal design with a diecast back plate a clean industrial aesthetic the
2:46 aforementioned perforated heat sink fins and of course icx as a superclocked card
2:53 this sits in the middle of evga's lineup with a 100 MHz bump over the reference
2:58 design and we'll be running it on our RGB test bench so it's a core
3:03 i77700k at both outof the box and
3:06 overclocked speeds time for the fuzzy donut of death yes fur marks back and so
3:13 are the settings from the back plate benches stock settings save for the
3:18 maxed out power and temperature targets the results well that's unsurprisingly
3:24 the first interesting aspect of the icx design there are a lot of them for the
3:30 GPU it was stable at 68° Centigrade
3:33 while the memory came in at 80 and the power delivery hit 81 all of this with
3:38 no thermal throttling traditional tools
3:42 like ferm Mark's integrated GPU temperature readout would have only
3:46 shown us the 68° figure which means that
3:49 already icx is doing its job so then we gave it a tidy 100 MHz overclock to both
3:55 core and memory keeping in mind of course that the superclock 2 is already
3:59 over clocked out of the box and went back to Tim Horton's for another fuzzy
4:03 donut and 68° Centigrade on the GPU 80
4:07 for the memory and 81 for the power delivery again zero throttling I'm
4:10 noticing a pattern here the Super Clock 2 IX is a good card and measures up well
4:16 to the aorist that we checked out recently but this sensor Tech just
4:21 doesn't really seem to do anything for performance directly and under normal
4:26 conditions both fans Go full blast when the cards working hard and sit idle when
4:31 you leave it for a while so why did they
4:35 bother developing this where could it make a difference well there are a
4:38 couple of situations one of which we caught on our thermal camera naturally
4:43 because the independently controlled fans spin Up and Down based on the
4:49 temperatures in their corresponding zones the total time each fan needs to
4:54 stay spun up can be optimized for a quicker return to quiet operation
5:00 so with Precision we can see the temperatures winding down and the
5:05 respective fans slowing down after we
5:08 close a 3D application Situation Number
5:11 Two is less to do with Acoustics and more to do with longevity not every
5:16 video card enjoys the luxury of an open test bench or a full ATX Tower and hot
5:22 recycled air or airf flow restrictions
5:25 in smaller cases could lead to higher
5:28 temperatures for the DRM reducing its efficiency hurting performance and
5:33 shortening its lifespan so with our
5:36 obstruction in the way of this fan we can see some car temperatures Rising
5:42 even when the GPU is not being stressed this is a likely scenario in a compact
5:47 case and IX ramps the fan accordingly
5:51 cool literally in our perfect world
5:54 there is still some work to be done here independent control of the fan curves is
5:58 neat but a robust implementation of a feature EVGA is teasing right now that
6:04 would allow other system coolers to be controlled as well would allow us to for
6:09 example point a side panel fan at the card's back plate which reached a toasty
6:14 74° Celsius in our tests back plates
6:17 don't normally contribute to video card cooling much if at all but in this
6:23 manner it's possible that it could so
6:26 what do you guys think then would you pay extra for more temperature answers
6:30 do you appreciate the extra control let us know in the comments
6:34 below Synergy is really freaking cool it
6:38 basically works like magic okay it's not magic it's complicated software
6:42 engineering but the end result seems like magic you can share one Mouse and
6:47 one keyboard between two computers so
6:51 you no longer have to think about like oh do I need to do something on that one
6:54 or that one no you just drag the mouse from one to the other and boom you're
6:59 switched it's amazing and it gets even better you can actually do it between
7:04 computers with completely different operating systems Windows Linux Mac you
7:08 can drag a single Mouse across them it's amazing they've got a basic and a pro
7:13 option with onetime payment for Lifetime access and the features include even
7:18 advanced stuff like clipboard sharing between the computers so check it out
