The Intel Laminar RM1 stock cooler has recently been tested with the Core i5-12400 by Chinese news site 163. The RM1 will be included with the upcoming Intel 12th Generation Core 65 W Core i3, i5, and i7 processors including the i5-12400. This mid-tier cooler positioned underneath the Laminar RH1 doesn't feature LED illumination instead opting for a blue colored ring. The cooler was tested by running the AIDA64 FPU stress test for 8 minutes where the i5-12400 reached a maximum reported temperature of 73°C with an average of 70°C. The processor drew a peak of 89 W with an average of 81 W while the RM1 fan reached a speed of 3100 RPM which was described as audible by the tester. The Intel Laminar stock coolers will be announced alongside the new 12th Generation Alder Lake-S desktop processors on January 4th.

Copper is nice. But why the hell are they painting the metal black?? First, it's an additional layer that worsens heat dissipation, second - black is a colour that absorbs energy, in contrast to white/metal finish which reflects it...

Plastic, with no large metal surface.

Not impressed at all. Sure it's ok, and is better than nothing, but I'd want to buy the CPU sans cooler and use my own solution.

+ 10c once it's in a case.

Yes, your right. All those temps they report are useless. There is no info about ambient temp either. But at least we get a look at what the cooler looks like.

R-T-BIntel has a love affair with that dow corning stuff, so likely that.
If so, it's not garbage.
svan71+ 10c once it's in a case.
Nonsense. In a well ventilated case the difference would be minimal.

It's not painted. The coating used doesn't really affect heat dissipation. There have been black heatsinks for years now.

Just about as useless all the temperature numbers with an Aida FPU test.

If itit was on Windows 11 it would be 20c Butters.

While I have to give credit for Intel for updating their stock cooler FINALLY, I am actually not impressed with the results. As some have pointed out, this was tested outside a case. No OEM will sell you a PC that is open bench. So I feel once this CPU and cooler gets slapped into a casing with limited airflow, its going to run hotter than 80 degrees C. On top of that, this was tested with an ambient temp of 20 degrees C. Now how many people actually stays in a place where it remains 20 degrees C all the time? In tropical countries, 30 degrees C is common. So I can't see how this cooler is going to prevent the CPU from throttling prematurely.

FreedomEclipseThat's actually not too bad considering it's cooling 6 cores
about the same as a Wraith Stealth in a closed case with "normal" airflow, my 3600 reached 68c (but the Stealth contain no copper core iirc)

still ... the "fins" around the fans are not ... metal (well it count like the fan frame on a Wraith, but much bigger) and it still use push pins ...

but, that still an improvement over the old stock cooler design from them ...

It's not really garbage. It offers consistent perfomance that doesn't really vary over time. That's why they like it. It's problem is that performance is rather poor vs aftermarket pastes.

Actually now that you mentioned about the plastic part, I took a closer look at the picture. Turns out that there is no difference between this cooler and the previous update from Intel by making it black. The extra fins sticking out are plastic, not metal.

Maybe not very significantly but it does affect heat dissipation. That something exists for years doesn't mean it's good. This cooler definitely is designed more for looks than efficiency.

It's a stock heatsink which handles stock loads. Most who oc just replace them.

I just got a ThermalRight ARO-M14G in a Zalman Z1 Neo Case (it fits even with the 140MM fan)

While true, stability is important to Intel. And the cost is likely to be favorable as well.

Stealth is barely acceptable. I used to get high 80Cs with 5600x@std in well ventilated case prime95 max heat . Idle was like 45C. Wtf?
With CM Hyper 212 black rgb . Dropped 20 C to mid 60s p95 max heat. Idle low 30s C.
Undervolted and single core boost +100mhz it runs around 57-58C now on prime95.
Heavy gaming + rtx 2070 Super = mid 60s @ 21C ambient.

It actually helps heat dissipation. It's an electrolysis ceramic coating that's extremely thin. And not only does it look good, but it actually stops the aluminum-oxide layer from forming on the metal. The aluminum-oxide layer is less conductive to heat than the ceramic coating. There is actually some pretty interesting studies on it, but a picture is worth 1000 words:



In this picture, a ceramic resistor was used to generate an exact amount of heat. The bare aluminum is on the left, the coated aluminum is on the right. The coated aluminum worked better to dissipate the heat and keep the resistor cooler.

It's a different process than anodizing.

You make a good point, with all my old coolers when they get anodised coating they look crap and perform a little worse. And they all have it now, even when inside the whole time and well looked after !

Umm... Don't you want the radiator to actually be HOTTER? You want resistor to get cold - heat should get transferred to radiator making it hotter and dissipate the heat to the air via fins. This picture shows that pure fins are hotter and coated are colder - more heat remains in resistor, less gets dissipated via cooler coated radiator...
Note that the heat was probably measured from OUTSIDE with something like thermovision camera. Inside coated radiator there probably is more trapped heat...

edit: ok I noticed that the picture shows the resistor too and it seems to be colder... Perhaps you're right, unless that white colour is clipped... I'm not sure what to think...

And the resister IS cooler on the right with the coated heatsink. The radiator will be cooler as well if the heat transfer to the air is more efficient. If you are transferring more heat to the air, the amount of heat in the resister and heatsink is lower, and their temperatures are lower. Which is the case with the coated heatsink.

A hotter heatsink means the heatsink isn't dissipating the heat to the air.

You're probably right. Though if we turned things around and measure with thermovision camera how good at cooling the fridge is, we would see that it has ambient temperature from outside and could wrongly assume that it sux at cooling. I'd be more convinced if there was a thermistor INSIDE the resistor.

That doesn't work because the fridge isn't generating its own heat on the inside.

I think they lost an opportunity to put a standard fan instead of their usual custom fan. It would be interesting how it fares with a better fan than that.

Totally
R-T-BOn LGA1366 tower coolers it used to come in a tube for you to put on.

Fun fact, the stuff was bad even IN A SEALED TUBE. It would turn to pure powder in about 2 years.
2 years, that's a lot better than thermal grizzly. Had a tube that I bought last year that i didn't end up needing. Couple weeks ago I fished it out of the drawer I had it in still unopened in it's blister pack. Stuff was completely dried and rock hard. I thought it was just end that had dried clogging the tube. So i cut the tube open with a razor knife and found it was bone dry rock solid all the way through.
