Intel Designs New Stock Coolers to go with 12th Gen Core "Alder Lake" Processors

With its new Socket LGA1700 heralding the first change in the physical dimensions of the processor's integrated heatspreader (IHS), Intel will introduce the first major redesign of its boxed retail stock cooling solution in over a decade. The Socket H-series (LGA115x/LGA1200) stock fan-heatsink has undergone several minor redesigns over the years, with regards to heatsink mass, the presence or absence of a copper core, the spiral or radial orientation of the aluminium heatsink forks (which affect surface-area and mass); although with what we're seeing in leaked Intel slides, the company's next stock coolers could look significantly different.

The Intel Laminar L-series fan-heatsinks come in three distinct variants based on the TDP of the processor they're bundled with. The Laminar RH1 (H equals "high") could be bundled exclusively with Core i9 SKUs that have 65 W TDP on the box, but have PL2 values well above 200 W. The Laminar RM1 (M equals "mainstream" or "medium"), will be bundled with Core i7, Core i5, and Core i3 SKUs that have the same 65 W TDP, but slightly lower PL2 (or at least a trade-off for higher noise). The Laminar RS1 (S equals "small"), targets entry-level Pentium and Celeron chips.
The exact designs of these coolers remain unknown. The Intel slide talking about these depicts a design not too unlike the outgoing one. It however, comes with a disclaimer that the renders are "for placement only," which means they may not look anything like the final design. These are still top-flow, but with the fans also having some lateral bleed airflow. The key difference here is that the fan is nestled inside the heatsink, and surrounded by extensions of the fins, so some of the lateral airflow ventilates these bits, before going onto other hot components near the CPU socket, such as the VRM.

It's also interesting to note that while the Laminar RM1 and RS1 (medium and small) are shown with push-pin retention mechanisms not unlike what we have now; the premium Laminar RH1 has a spring-loaded bolt mechanism that possibly includes a backplate. This is harder to install or remove; but applies a more uniform retention pressure on the IHS.

Also, the fan inside the Laminar RH1 is depicted as being illuminated by an LED diffuser along the bore of the fan cavity (which renders this design useless?). It remains to be seen if this is single color (i.e. Intel's favorite shade of blue), or if it's RGB. The Laminar RM1 has a less pronounced illuminated ring that doesn't obstruct any of the lateral airflow. Intel's rival AMD has been bundling RGB-illuminated Wraith Prism cooling solutions since the beginning of the AMD Ryzen era.

You'll see none of these coolers in 2021, as Intel plans to debut the 12th Gen Core "Alder Lake" family this year with only the Unlocked K or KF SKUs, which lack any included cooler. The "locked" 65 W SKUs are expected to join the lineup only by Q1 2022.

What copper? I don't recall Intel making anything more than bare minimum for the last 10 years.

Up until Sandy Bridge, their HSF had a copper core. This made a comeback with 10th- and 11th Gen.

Maybe its time for me to repaste the 10400F, I don't recall seeing any copper chunk.

I'm pretty sure that the copper core was only used for 95W TDP.

Weird. I remember my good ol' 3770K and the cooler did not have copper anywhere. Small simple aluminum radiator.
Still have few 2700k and I did not see any copper either. Maybe I will look again as a reminder.

Correction : Haswell also has copper core one, my i5 4590 came with the copper core one. All aluminium one started with Skylake.

Why would you need 3 different cooler designs if the 65W* is truly 65W ?

Because 65 W is just PL1. PL2 wildly varies across the lineup. They're also segmenting along noise and aesthetics (RGB).

Can't wait for the heat pipe shortage to be over.

So how come I have 4670K and 4690K with Intel coolers, which have a cooper core?:D

With the political unrest in Ghana, aluminum prices shot out of space...hard times for PC industry no joke about it.

Another terrible box cooler from intel, what a surprise. Why do they even bother with a redesing I wonder

DeathtoGnomesLooks like an old Zalman.

An extensive review of the Zalman CNPS7000-Cu and -AlCu, the current top of Zalman’s extensive P4 cooler line. They depart from the last generation of Zalman’s top P4 coolers from by being radial rather than “fanned”, and by having an integrated fan rather than one on an extended overhead bracket. How quiet and how cool? July 2, 2003
I had one of these BITD.

yep ... i was about to notify it ....

well the design seems horrible (seriously what with the uselessly fancy shape ... ) blue only for the "high end" instead of a logical RGB (or better aRGB) to permit user choice for color ... mid end has a better ring design, still blue only tho ...
i get it they are going after Wraith Stealth/Spire but man ... if they meant to, they should do it right ... the RH1 looks ridiculous.
When you go after your concurrent, you aim to do better or equal, not worse ... (for now it looks worse at all level, who know ... maybe the performances will ... naaah... i highly doubt it)

Hi,
Why would they bother with a cooler like this :confused:
