I remember spraying an upside-down can of compressed air into my 212+ to make 5GHz benchmarks on FX-4100. It couldn't cool my Phenom II 1090T at 4.1GHz, but for <$25 I guess I can't complain..

I ran 4.9 GHz FX 6300 with Hyper 103, there's something really off about your 212.

Piledriver had way less leakage than Bulldozer, but I doubt you could run that frequency under stress anyway.

This is what I was trying to cool.

I also pushed FX 6300 to 5.228 GHz on Hyper 103, but I disabled two modules and it wasn't stable at all. I needed 1.72V, because my board had weak VRMs and no cooling. Anyway, that's not the point. 212 shouldn't need compressed air for 5GHz and it likely can cool Phenom 1100T at 4.1GHz.

Sorry you feel that way.. I saw what the cooler can do.. maybe I had a bad one? Show me the numbers :)
What would you like to see, I've got the 212 cooling my 10700K@5GHz right now.

They made them with pushpins too? What little respect I did have for it has been whittled away that much more :D
No, the Gammaxx 400 uses push pins. It's truly a shit cooler.

I’d like to see my favorite! It’s what I always run..

Linpack Xtreme 1.15, available here :D

Of course I don’t expect you to be able to run it.. but my mind would be blown if you could though..

70C with only 2 cores is pretty bad for that voltage on piledriver.
Motherboard was really at its limits and I highly doubt that it really did supply that many volts. There was no scaling past certain point and I think that motherboard just reported more than it actually supplied. The board in question is Asrock 970 Pro 3 R2.0. It's a cheap 4+1 phase board without VRM heatsinks and I had to set voltage to the max, I also maxed out LLC. It wasn't a stable overclock, it was a suicide run. I just wanted to see at what point my system lost any level of stability and of course those 5GHz. If I had an actually decent board, I certainly wouldn't need 1.72 volts in BIOS. And with better cooler, which I did have (Mugen 4 PCGH), I should have reached 6GHz on air during a suicide run.

Ran it just fine. So I guess mind blown?

And this is in my hot office with a room temp of about 26°C and in a mITX case with not the best airflow, and I'm using the iGPU which adds some heat load to the CPU cooler.

I find it disadvantageous to run direct contact heatpipe coolers with liquid metal because the added heat slows the gradient inside the heatpipes. One measure is take advantage of the decrease in cpu temperature into an effective undervolt to kill power even more; eventhough lower temperatures by themselves are an effective management of current output I still haven't seen one soul without worse case temperatures after liquid metal on air cooler application.

You can bash some iterations of the Hyper 212 for fiddly, low-pressure mounting solution and cheap sleeve bearing fans, but the 4-heatpipe and relatively dense fin stack has always made it a capable cooler provided you can get enough airflow over it.

I've seen at least four fan designs on the 212 over the years and the smoked wavy ones (left image) seem to have a short life and sieze up within a couple of always-on years, whilst the sickle-flow fans (center image) are great for longevity and low noise but definitely down on cooling performance. IMO the best performing fan (if not the quietest) was the one on the right - all of those I've seen are still going strong but they've not been made for close to a decade now....

So, small fan hub with wavy blades = fan dies
Big fan hub with 5 curved blades = very quiet but struggles with higher TDP
Big fan hub with 7 curved blades = good all rounder, noisy at max speed but cools well

So, bashing the 212 is both justified and not justified. There must be at least five different products all sharing the same name and some of them are good and some of them aren't

I was going to say that upgrading the fan to Nidec GT would take an interesting dive. I don't think sickle flow variant is down on performance though, the cooling effectiveness is about pressure in the fin stack, not cfm related in my opinion.
PS: as the pictures demonstrate, design-wise it is the same as Freezer 34, but Arctic definitely is ahead in clearances. You couldn't fit a flush fan mount to the fin stack, so Arctic still has its place.

Yup mine was the top left, had a nearly dead fan.. it wanted to die.. felt so chunky..

It's the stock coolermaster fan, not sure what it was running at I just have the motherboard set to the standard fan curve that comes as default. It's not loud in the Factal Case though.
So, small fan hub with wavy blades = fan dies
I think these are the only one's I've seen(and the RGB variant of the same fan). And they all die after a year or two.

I wonder if the people hating on the 212 are the ones with those shitty sleeve-bearing fans and their problem is that the fans are starting to go and just don't spin fast enough to cool properly any more.

I don't think sickle flow variant is down on performance though, the cooling effectiveness is about pressure in the fin stack, not cfm related in my opinion.
It's a bit of both. The 5-blade sickle-flow fans have fantastic pressure but low cfm, probably too low to benefit from the added pressure, since pressure needed is proportional to the square of the CFM. The 7-blade sickle-flow fans have a 40% more aggressive blade angle, which translates linearly to a 40% higher CFM at the same RPM.

The leyman version is that high-cfm fans on a radiator/dense fin stack also need more static pressure, otherwise they can't actually reach their stated CFM values.

Whilst both the sickle-flow designs have ample pressure, the 5-blade fan has too much pressure and too liittle CFM for this application, it's better suited to thick radiators or heavily filtered intakes.

I couldn't use that fan lol.. it was too far gone.. if it was just a thin brass sleeve in it, it was highly worn because the rotated in an ovular fashion :D

I used a 120x38 because I have a few. I was trying to cool an X5690. Like I said (or maybe I didn't).. I did run Linpack on at 4GHz with it, and 4300 with my 3770K. Although the only real difference was I did not run any power saving stuff.. all that was turned off for one speed one voltage and full power in a full sized case with plenty of air.

Maybe I didn't use enough TIM? I will forever wonder for the next 20 seconds.

Just kidding, but I am curious about the TIM part.. Hm.

Don't forget: for pressure to work, the fin stack has to have crimped ends and the fan has to sit flush. Somehow I don't think any of this will work with CM, although I love it being the first.

I wanna point out for the last time: wouldn't you say direct heatpipe coolers would perform better if they came with a temperature sensor at the top of the fin stack?
These heatpipes have a heat flux chart that vary according to the source-radiator temperature difference. The sensor could help in modulating the fan so that the heatpipes always keep constant temperature difference with the fin stack in order to maximise linear conductance, maintain the best performance for the least amount of sound volume. This could even be carried via to the shroud fan's connectors to the motherboard.

I have a Hyper 212 Black Edition cooling my Ryzen 3800X at 4,275/4,300 MHz with the voltage at 1.258 without the temperatures exceeding 85C in AIDA64 FPU stress test. Im using MX-4 paste.

Maybe I wasn’t using enough paste? Kinda wish I didn’t throw it away now.. not that it matters there is no AM4 mount for it because it’s so old. Maybe I will see if I can find one used locally for cheap..

Here’s the last time I ran AIDA64 FPU on February 8th because @Toothless asked how I was cooling a 3800X with a Hyper212.

The Black Edition has a nicer finish on the base, and appears flat unlike the older 212 I had before. Mounting hardware is improved over the old 212’s as well.
