0:00 so you might have seen our video a little while back where we chopped up a
0:04 gtx titan so it could fit in a single
0:07 pci express slot with a card installed
0:10 right next to it that mod included water cooling though and we thought
0:15 why don't we try and do one better what if we made a single slot card that's
0:21 air-cooled alex why don't you quit your bitchin and get
0:25 to work so get your angle grinders revving because the gtx titan is going
0:30 on the chopping block once again
0:43 experience MSI's gs63 vr laptop now with
0:47 NVIDIA's GeForce gtx 1070 max-q check it
0:51 out at the link below making a double slot card the height of
0:57 a single slot card with air cooling isn't particularly easy if it was then
1:04 this would be a lot more common than
1:07 this this video has been a long time in the
1:11 making so we got to work measuring every important bit of the titan to make a
1:15 solidworks model which will actually link if you guys want to make your own
1:19 mod to one of these for whatever reason with the model for the single slot
1:24 adapter made it was time to print now pla filament would pass the glass
1:30 transition temperature when the titan was stressed turning into a deformed
1:34 blob so we ended up using abs
1:38 with the 3d printed part in hand well one thing became clear and that's
1:42 that our calipers hold a zero like a drunk hits a bullseye
1:47 but all the critical dimensions were close enough so we just needed to
1:52 perform a little bit of massaging to get everything to uh
1:56 kind of fit together for our next trick then we'll
2:00 need a low profile fan thanks cooler guys you have everything
2:05 now we were hoping to cannibalize the fan and mount it where the original fan
2:10 went but unfortunately this press fit bearing
2:14 holder prevented us from doing so so it was time for super cannibalization with
2:19 this angle grinder and the savagery continues the wonderful
2:25 cooler mounting plate for the titan well
2:28 i'm afraid that anything that was going to be too high to fit in a single slot
2:32 was gonna have to go excellent so everything seems to be
2:37 coming together fairly well let's move on then to the final step
2:42 which brandon dubbed torture porn for nerds
2:46 chopping up the heatsink originally we thought that just the good
2:50 old angle grinder would do the trick allowing us to relatively easily slice
2:55 through these thin fins unfortunately that ended up taking too long and
3:00 grinding aluminum is actually really sketchy
3:04 so we moved on to our favorite method of heatsink chopping the reciprocating saw
3:09 and oh oh god oh no
3:13 oh please stop oh the humanity
3:20 like we said before using an angle grinder or a reciprocating saw those
3:24 would be terrible ideas so we ran out and bought a belt sander
3:29 to ensure that we didn't cause any more unnecessary harm to the heat sink while
3:33 we cut down its size it really is amazing how much easier
3:37 things are when you have the right tool for the job with the heatsink now at the
3:41 right height we just had to remove any loose bits of aluminum because if one of
3:45 those crosses the traces on the pcb it's game over and then
3:50 slap it all together it's actually a little bit easier to
3:54 assemble now than stock since there are way less screws
3:58 so that's a plus the fan mounts with some strong
4:02 double-sided tape the see-through panel had to be glued onto the outside instead
4:06 of the inside like on the original model but i mean this was
4:10 so that we could maximize the area of the fins because in truth having the
4:15 glass on the inside would have meant about 20 percent less cooling
4:18 unfortunately though when we went to test it the fan wouldn't work
4:23 possibly because of the grinding we could have gotten another fan but if
4:28 we're being honest that just wasn't going to be enough airflow anyway so we
4:32 went back to the drawing board and designed a 140 millimeter fan to dryer
4:38 vent adapter and a new single slot cover inspired by
4:42 server gpus without a hole for the fan
4:46 the good people at my mini factory printed that up for us the parts arrived
4:50 and we could finally smash them into the computer as hard as you guys are
4:54 smashing the like button right now so we bolted the adapter to a knock to a
4:58 140 millimeter industrial fan at max speed and then squeezed it into the case
5:04 before connecting the dryer vent to the graphics card we added some foam to the
5:07 back to prevent the dryer vent from shorting anything out we then attached
5:12 the vent the red green way lots of duct tape and finished it off with some tuck
5:16 tape for that industrial quality seal
5:20 now it just needs to be encouraged in and we're good to go
5:27 oh my god what is this
5:31 wow this actually looks
5:34 like shockingly not
5:37 i mean the dick butt is sort of unnecessary but uh
5:42 does this work where does it exhaust from okay that seems to be a bit of a
5:46 design flaw there yeah did you not think to maybe cut vents here like single slot
5:51 graphics cards usually do okay okay okay
5:54 okay oh boy oh boy
5:57 oh buddy oh boy you better shut this baby down
6:02 before you overheat here and while we could have spent the rest
6:07 of the day taking it all apart modifying it carefully and putting it back
6:11 together it was easier to whip out the saw and hack off the last inch of the
6:15 cover to give it some breathing room which
6:20 hardly helped it all of course it thermal throttled again
6:23 because our heatsink was crazy restrictive and getting almost no
6:28 airflow also this whole thing was kind of a dumb idea
6:33 alex did the calculations before he even
6:36 started the project and no matter how much air you push across the fins if
6:40 they're that size you're not going to get the cooling needed for a titan so i
6:45 guess the real takeaway from today's video is that math exists for a reason
6:53 yeah some of us already knew that ring ring who's there nobody this is
6:58 just my hand but if i was using a real phone and i was calling ting the mobile
7:03 carrier that's focused on customer satisfaction i would be talking to a
7:07 real person no robots no automated phone
7:10 tree no nothing because they actually care and what's crazy about that is you
7:16 don't pay extra ting users pay only for the voice and
7:22 data that they actually use with the average bill being only 23 bucks a month
7:27 per device and if you're stuck in a contract they'll even cover 25 of your
7:32 cancellation fee up to 75 i mean that
7:35 could be three months of your cell service they even have lower mobile data rates
7:41 than ever before with data now just 10 a gig beyond the first gig so head over to
7:47 Linus.tang.com we've got that linked in the video description and try out their
7:51 savings calculator it'll tell you based on your last few bills and your usage
7:57 whether you'll save money on ting then when you sign up at our link you'll also
8:01 get 25 bucks in service credit or towards a new device
