00:00:00.160 --> 00:00:08.000
so everyone knows that for a CPU to last longer and perform optimally it needs to

00:00:05.600 --> 00:00:13.440
stay cool which makes it all the more confusing that Intel over the last few

00:00:11.040 --> 00:00:18.000
generations at least according to comments from the

00:00:15.040 --> 00:00:23.439
tech community has been using seemingly the worst possible thermal compound

00:00:20.720 --> 00:00:28.640
between the dyes of their processors and the integrated heat spreaders that go on

00:00:26.080 --> 00:00:33.200
top of them but the problem is that the only way to evaluate that thermal

00:00:30.560 --> 00:00:36.800
compound that we have now is to take off the spreader replace it with something

00:00:34.719 --> 00:00:40.559
else and check the results but we're actually changing a lot of variables

00:00:39.200 --> 00:00:48.160
when we do that so we devised a test to find out once and

00:00:44.320 --> 00:00:50.480
for all just how bad is Intel's thermal

00:00:48.160 --> 00:00:56.640
paste alex here has got an entire bag of Intel cpus with

00:00:54.239 --> 00:01:00.640
their junk thermal compound and we're going to be harvesting all of it and

00:00:58.960 --> 00:01:06.720
then comparing it with the well-respected nth1 from Noctua a

00:01:03.840 --> 00:01:13.760
premium thermal paste on a d-lidded liquid metaled extreme edition CPU

00:01:09.920 --> 00:01:15.920
so come along for the ride

00:01:13.760 --> 00:01:19.840

00:01:31.759 --> 00:01:38.720
to get a baseline we first needed to apply some nth1 thermal paste from

00:01:35.840 --> 00:01:44.479
Noctua and mount the nhd15 cooler that we'd be using for our tests it performs

00:01:41.280 --> 00:01:47.280
as well if not better than large aios

00:01:44.479 --> 00:01:50.799
but is way easier to mount all of our testing was done in our conference room

00:01:49.040 --> 00:01:55.200
to keep ambient temperatures locked at 24 degrees at stock speeds with

00:01:53.280 --> 00:02:00.560
multi-core enhancement turned off and the CPU fan at full blast

00:01:58.000 --> 00:02:05.200
30 minutes starting now while our control thermal test was running we had

00:02:02.880 --> 00:02:10.399
some time to begin what we're calling the grand tim harvest

00:02:08.479 --> 00:02:14.640
we aren't totally sure if these processors work but

00:02:12.480 --> 00:02:18.640
we don't want to just destroy them like so many things d-litting is pretty

00:02:16.720 --> 00:02:23.120
simple when you have the right tools place the CPU in the little vise tighten

00:02:21.040 --> 00:02:27.680
until the top moves a bit and then remove the lid which normally you would

00:02:25.280 --> 00:02:32.640
do by hand but these ones seemed pretty reluctant to let go and we wanted to get

00:02:30.319 --> 00:02:36.800
this over with once all the cpus were opened we scraped off all the thermal

00:02:34.959 --> 00:02:41.200
interface material we could get at with a guitar pick and then carefully placed

00:02:39.280 --> 00:02:46.239
it on an esd bag now you might be thinking guys

00:02:43.760 --> 00:02:51.599
those are third gen core series chips that came out six years ago

00:02:48.720 --> 00:02:56.560
how can this be a fair comparison well the longevity of Intel's paste is one of

00:02:54.319 --> 00:03:01.519
the main justifications that we have heard for them using it also it's a heck

00:02:59.599 --> 00:03:06.800
of a lot easier to get a bag of third-gen chips than uh 8th gen

00:03:05.200 --> 00:03:11.519
chips oh the savagery

00:03:09.440 --> 00:03:14.080
look at this this is like they came in and

00:03:12.480 --> 00:03:17.599
wrecked up the place well you don't have to do that to them

00:03:15.680 --> 00:03:22.800
well that's a fair point okay so oh so this is it yeah that's

00:03:20.720 --> 00:03:29.280
all of it right there don't blow on it i'm not gonna blow on it so this is our

00:03:26.080 --> 00:03:31.760
harvested thermal interface material

00:03:29.280 --> 00:03:39.040
from four cpus this looks like it should be more than enough for our 7980xe

00:03:39.040 --> 00:03:45.360
after inspection we found that our first application of thermal paste was

00:03:42.959 --> 00:03:49.120
excellent so these results should be perfect for our comparison do you think

00:03:47.440 --> 00:03:53.680
there's like a good way to get this on there i think we're in uncharted waters here

00:03:52.080 --> 00:03:58.640
right now i hadn't really given it a lot of thought to be perfectly honest with you

00:03:56.799 --> 00:04:03.599
several methods of applying the old thermal goop were considered including

00:04:00.720 --> 00:04:07.280
just placing it onto the CPU but without a way to spread it around we

00:04:05.680 --> 00:04:11.519
were concerned that we wouldn't get adequate coverage

00:04:08.799 --> 00:04:14.799
mashing it into a ball seemed promising but it just kind of

00:04:13.040 --> 00:04:19.919
flaked out and turned into a weird powder finally we turned to what seemed like

00:04:17.919 --> 00:04:24.639
the soberist idea soaking it in alcohol

00:04:23.040 --> 00:04:30.080
is that doing anything i'm not sure yet alex although this

00:04:27.199 --> 00:04:35.280
doesn't seem like the best of ideas it's actually not the worst ever either the

00:04:32.720 --> 00:04:41.440
alcohol should allow what is currently thermal dust to turn back into more of a

00:04:38.880 --> 00:04:45.360
paste for application and then quickly evaporate away

00:04:43.120 --> 00:04:50.320
our spudger ended up being too fine of a tool so we swapped it out using the

00:04:47.759 --> 00:04:54.720
allen key from the d-litting tool as a makeshift pestle for our bottle cap

00:04:52.720 --> 00:04:58.800
mortar making a reconstituted thermal paste

00:04:57.600 --> 00:05:06.000
here oh i don't miss it what's going on i

00:05:01.360 --> 00:05:06.000
spilled the alcohol so ridiculous

00:05:06.320 --> 00:05:11.360
this alcohol spill might have been a blessing in disguise

00:05:09.360 --> 00:05:14.320
this may be one of the dumbest things we've ever done yeah i was trying to

00:05:12.560 --> 00:05:18.240
think of dumber things but this is really up there

00:05:16.240 --> 00:05:22.160
should we try to spread it out more or i mean we got the particle size pretty

00:05:20.240 --> 00:05:26.479
small ish with the tim spread out to the best of

00:05:23.919 --> 00:05:33.120
our abilities all we could do was wait for the alcohol to dry

00:05:33.120 --> 00:05:39.360
like i guess we should just go for it now

00:05:36.800 --> 00:05:43.520
this we have no choice but we've committed this much time and

00:05:41.039 --> 00:05:48.880
energy to this now initial temperatures at idle had us at just over six degrees

00:05:46.400 --> 00:05:53.039
over ambient meaning that our application worked at least to some

00:05:51.039 --> 00:05:57.759
degree well it might just be more oddly now it was like 30 watts before outfit

00:05:55.360 --> 00:06:02.160
like eight okay so you don't think it's the

00:05:59.919 --> 00:06:06.400
material heating up and spreading out i think it's just Windows as all the way

00:06:03.919 --> 00:06:10.639
started but we wouldn't know how well it worked until we hit it with an intense

00:06:08.639 --> 00:06:15.199
load uh it didn't i mean it didn't instantly

00:06:12.800 --> 00:06:19.319
overheat but this is probably a fair bit hotter

00:06:16.319 --> 00:06:19.319
88.

00:06:20.880 --> 00:06:29.120
now our earlier test gave us a maximum temperature of 60 degrees and an average

00:06:26.479 --> 00:06:36.000
temperature across the course of 50 degrees while maintaining a CPU power of

00:06:31.919 --> 00:06:38.880
about 150 watts with our reconstituted

00:06:36.000 --> 00:06:45.120
Intel tim we almost immediately blew past that reaching a maximum of up to 89

00:06:42.240 --> 00:06:52.240
degrees ouch before settling into an average of 75 degrees to be clear this

00:06:49.680 --> 00:06:56.160
is a totally acceptable number that shouldn't harm the processor within its

00:06:54.479 --> 00:07:03.599
expected lifespan but 25 degrees more than the enthusiast

00:07:00.400 --> 00:07:06.560
solution still isn't great but

00:07:03.599 --> 00:07:10.080
is the problem the paste or the application this is the real moment of

00:07:08.880 --> 00:07:18.000
truth because we weren't expecting it to perform as well anyway right

00:07:15.039 --> 00:07:22.880
did it spread actually it did i think if we described that as

00:07:20.160 --> 00:07:27.680
sub-optimal but adequate it doesn't seem to have um

00:07:25.919 --> 00:07:32.880
liquided up at all so with our decent enough application we

00:07:31.039 --> 00:07:38.000
feel at this point that it's safe to say that the 25 degree difference was at

00:07:35.440 --> 00:07:44.960
least largely due to the poor thermal conductivity of the paste that is inside

00:07:41.599 --> 00:07:47.120
the CPU and supporting our theory is the

00:07:44.960 --> 00:07:50.800
fact that this difference is actually pretty close to the temperature

00:07:48.639 --> 00:07:56.560
difference that you can achieve after deleting a CPU and replacing that stock

00:07:54.000 --> 00:08:01.599
thermal interface material so to answer our original question there are a number

00:07:59.280 --> 00:08:07.039
of variables that you end up changing when swapping out thermal paste in your

00:08:04.000 --> 00:08:08.720
delidded processor including mounting

00:08:07.039 --> 00:08:13.199
pressure the thickness of the application the silicone seal the

00:08:11.199 --> 00:08:20.639
flatness of the heat spreader but as everyone expected it's Intel's choice

00:08:17.039 --> 00:08:23.039
of a longevity optimized tim rather than

00:08:20.639 --> 00:08:29.680
a performance optimized one and their decision to eschew solder that

00:08:26.000 --> 00:08:31.039
makes up the bulk of the difference

00:08:29.680 --> 00:08:35.200

00:08:33.120 --> 00:08:39.680
