thermalright LGMRT and TS140P disagree with you.

Let me be clear that I'm not arguing, I'm just trying to get a better understanding.
It's the other way around. That's why i was suggesting the sw3. At 2k RPM they're very much better than any other fan. At 600-800 (the RPM mark you should aim for, the difference should not be noticeable)
I didnt check the price on the links you posted tho....

Check for the aro m14 on other sites. It will give you similar performance to nh d15.

I remember turning on the computer for the first time and thinking the fans were broken since I could not hear anything and I had to inspect them visually to make sure. What I do hear is my reference 5700XT's low fan hum on idle right now (it's very faint). The fans on the Noctua and the fan on the PSU are silent. The Corsair Air Series SP120 PWM are as silent running as the Noctuas on idle and I can't tell how loud they get on load since all I hear is the card. I guess with the latest Bios, even the fan on the chipset does not spin. I've only seen it spin on boot. Does not even spin while gaming.



There is no reason to over think it. Any of the recommended fans will serve you well and you won't hear them on idle and even on load since other things will be more audible over and above these fans in the case.
You can't make comparisons on "idle" and "load" speeds..... And good fans with smart configuration, in a bedroom at night, do make a difference. A very noticeable one.

Here is a tall order: is there a reliable online shop in Europe that sells Thermalright products, and ships internationally?

For the record, I'm aware Thermalright has solid products. I've been using their True Spirit 120 for seven years now, albeit with a swapped fan in the last couple or so.

You aren't wrong, but the u12a is a 120mm cooler and performs within a few degrees.


This is only one source, but here's the u12a performing better than AIOs on LGA1151 sockets and most AIOs on AM4. Performance is less good on LGA2066 but that's probably due to the smaller cold plate on the u12a.

Alternate has websites in many EU countries. I think all orders are shipped from Germany

ALTERNATE-Webshops are available in: alternate.be alternate.at alternate.de alternate.dk alternate.nl
alternate.es alternate.pl alternate.fr alternate.it alternate.ch alternate.lu
Hope that helps.

I agree NH-U12A is a very good little cooler (I think NF-A12x25 fan is key), but it's not quite as good as many bigger coolers.

I think our link site test procedure is seriously flawwed because their delta temps are using "ambient temperature at the time of testing." That is most likely air temp in room, not entering cooler.

I don't consider any source that does not monitor and record air temp into cooler at same time CPU temp is recorded. Air temp into cooler / radiator is not the same as elsewhere in room and/or at different times
.. and changes with load and case fan speed.
.. air temp into air coolers effects CPU temp at full load at almost exactly a 1:1 ratio, so if air is 2c warmer so is CPU.
.. radiators not as close to 1:1
.. meaning delta results using air temp from anywhere else at any other time can eaily be off by 2c either way, espcially with air cooling.
.. that means actual CPU delta temps can easily be several degrees more or less than if using air temp into cooler.

.. even under best of conditions CPU delta temps vary a couple of degrees.

ciarlatano, others and I have verfied this in our own testing when using air temp into cooler vs room temp.

Well, so far I'm leaning towards a 2x140 setup for intake, and more specifically the NF-A14. eLoops are only available as 120mm, and the Silent Wings 3 are ~25% more expensive than the NF-A14.

Re-reading the article I do agree with your points. It's undeniable that the u12a is very good for its size.



As for air temperature into the cooler, in an open air test bench, can't you assume ambient temp in the room is roughly the same as air temp into the cooler? Assuming the room is ventilated?


I understand variations of 1-2deg can change CPU temps by that margin, but this seems to mostly be inconsequential error when looking at the scope of CPU cooler tests.


Not to mention, once you put a cooler in a case everything changes. I bet even two identical systems will perform differently solely based on tolerance stackups.

Many of us like PH-F140MP fans. Their specs are kinda deceptive in that they are lower than many others at full speed, but in the 700-1400rpm range they are better.
