compared to AMD Intel's box coolers are kind of an embarrassment their main
Workhorse for many years the
e97378-003 has about as much sex appeal
as its name would imply but what's this
at first you're thinking damn and tell
how you get all fine like that and then you're like
but are those even real and that's kind of where I find myself
today alongside their 12th gen CPUs Intel launched three new stock coolers
the rh1 rm1 and rs1
as you can see we only got two of them but they're the
most important ones and once we got them disrobed we realized there is a lot more
here than meets the eye Beauty and Brawn

for nearly 13 years Intel's consumer platforms used the same 75 millimeter
mounting hole pattern which has been great for consumers I mean who doesn't
want to carry their old cooler forward to their new system but with 12th gen
that's finally changed Alder lake is Intel's biggest performance leap in many
years and to pull it off they needed a new much larger CPU socket which appears
to be the driving force behind the new expanded 78 millimeter mounting holes
these obsoleted every previous Intel compatible cooler including Intel Zone
resulting in the creation of these standing at 47 and 69 millimeters
respectively nice the rm1 and rh1's new
design language is a refreshing change from the value optimized Intel coolers
of the past the larger model features knurled stainless steel captive thumb
screws for mounting a pleasing two-tone finish addressable RGB lighting and
enough cooling capacity for the core I9 12900 and 12900f processors that it
ships alongside as for the rm1 this
little guy borrows design cues from its bigger brother you got your black
anodized aluminum cooling fins sleeved 4-pin fan connector and stylish Crown
profile but there are definitely some cut Corners here the plastic push pins
are certainly an improvement over previous generations but they're plastic
and gone is the RGB lighting accent Machining and included backplate it's
the rm1 though that you'll find included alongside core I3 Core i5 and core i7
CPUs which means that this is the unit that most people will actually end up
with and while it appears smaller and
more basic and therefore probably worse
what's interesting is that Intel's entire multiplier locked Core Series
lineup all the way from I3 to I9 is
rated at the same 65 watt TDP which
immediately made us Wonder why wouldn't they just use the same
cooler for all of them to really understand what's going on
here we need to look at the performance of a few generations of Intel stock
coolers all of them were adapted to work on our MSI Pro z690a Wi-Fi motherboard
and we used a core i7 12700 as our standard thermal load Now Intel has
traditionally offered three mainstream cooling solutions a basic all extruded
aluminum fin heat sink a second more performant variant of the same this time
with a copper slug pressed into the center to add thermal mass and
facilitate faster heat transfer to the fins that's the one we're going to focus
on today and occasionally they've done these weird tall boy versions for higher
TDP chips these had remained essentially unchanged for the better part of a
decade until the introduction of the LGA 1200 socket for 10th and 11th gen chips
that saw our old standby here dumped for a younger sleeker cousin now with more
black and less Mass hmm
so Intel kept the construction method the profile the thin count and even the
performance the same and yet they dropped 17 grams of weight about 11
overall it turns out they did so by
Machining out more Copper from the center Slug and this is really cool
because it goes to show you just how much copper has gone up in price over
the last 10 years it's at the point where when you're operating at Intel
scale Machining out that 17 extra grams
of copper per heatsink then pressing it into pucks and recycling it manages to
be more cost effective than just leaving it in there now let's see how our new
units Stack Up starting with the rm1 we tested with blender BMW there's about a
five minute test on this chip in three different fan profiles in our noise
normalized profile the rm1 was disappointingly exactly on par with our
older style coolers then in the auto profile it managed well extremely
similar performance again within about half a degree and it full speed the rm1
managed to run as much as two degrees cooler across multiple tests but wait
how could that be that you've got no performance difference at one fan speed
and a significant one at another fan speed
well one factor could be the solid copper core at the heart of this new
series that's right in spite of the ever increasing cost of this metal Intel put
so much into these new coolers that they weigh nearly double the last gen design
we think that this could be to accommodate the aggressive turbo boost
behavior of 12th gen core CPUs but
there's a big asterisk on our results and that's fan performance while doing
research for this video we found out that Intel actually published the full
design specs for their LGA 115x cooler
family the older ones and digging through these we found out that there
were three manufacturers of the exact same SKU Foxconn Delta and nidec going
deeper into these documents we found that the fan RPM specification varies by
8.25 percent and that's on top of the
plus or minus 10 that the fan can operate at while still meeting Intel
spec if the new generation is a similar story
that means that we could easily see a larger performance Gap from just one
cooler to the next compared to one
generation of coolers to the Next Generation
with that in mind we still think it's worth testing the rh1 to see how it
might compare the differences were
underwhelming less than one degree
between the much taller version of the cooler and the little skinny chicken one
in both are noise normalized and full
speed tests it did manage to shave 15 seconds off our render and sustain a 50
megahertz higher clock speed throughout the run compared to the rm1 so the extra
mass in the cooler is making a difference I just feel like that
difference could have been bigger and I've got a question and tells you some
thick chunky fins here because a lot of
smaller fins would have had more surface area and therefore probably better
performance so I'm left feeling like Aesthetics took
a priority over performance in spite of the fact that these are shipping with
core I9 CPUs and on that note I didn't
even mention the cute little backlit spinner hubcap on The Fan Hub that's
definitely purely aesthetic now we didn't get to testing these
coolers against AMD's wraith offerings for a couple of reasons one is the
different mounting systems of course but that is the sort of thing that will be
happening in the near future with LTT Labs and the second reason is that we
just didn't really have to they're so much better you don't even need me to
tell you with that said I still need to commend
Intel for Value engineering a small but
measurable Improvement to their previous thermal Solutions and more than that I'm
glad they took the time to make this new generation of coolers just attractive
enough to not look horrible in the tempered glass side panel world that we
find ourselves in today they're also quiet enough to go unnoticed by most
people especially any of those of you who are lucky enough to also have a
presumably louder GPU so 12th generation
Intel is making the CPU industry competitive again we're reaping the
rewards that is after AMD made the CPU industry competitive again all we need
now is for Intel to finally drop their Alchemist gpus to shake up that side of
