NH-D14 is still one of the best coolers out there. The only reason it's a few degrees warmer than D15 is because it's fan's max speed is slower.Cheers.
Since, I'm choosing a normal RAM choice. I need a different cooler.
I've gotten a good 6 years out of the NH D14, time to move on.
Beating H50 isn't saying anything.I've been seriously impressed with the following:

It handily beat my corsair h50 push pull.
Beating H50 isn't saying anything.
34 is 124x157x103mm (WxHD) w/ 2x fans & 4x direct contact heatpipes, so finpack is only 53mm deep.
For comparison, Alpenfohn Matterhorn Pure is 138x123x158mm w/ 1x fan & 6x heatpipes in 75mm deep finpack and is only £33.95 and has 6x 6mm heatpipes.
Direct contact heatpipes vs enclosed base heatpipes is not a big deal, although I believe enclosed is better.
50% more heatpipe area makes a huge difference in performance.
2x fans vs single fan on single tower (even twin towers) makes little difference (1-3c). Add 100-200rpm to single fan and it performs the same as 2x fans at lower rpm .. and at full speed the speed difference is even less. 2x fans make more noise than single fan, so the added speed needed with single fan ends up being about same DB level as 2x fans.
I question the validity of their testing procedure. It shows 20c as air temp during all tests. Testing differeent cooler with different size fans having different airflow in a case running same fans at same speed for all tests will not give same temp of air into all the different coolers.https://www.overclock3d.net/reviews/cases_cooling/cpu_air_cooler_mega_test/39
The older freezer i32 was beating the Matterhorn by the looks of things, so number of heat pipes isn't everything.
They both look like decent coolers though tbh
I've not read any further, but I'm assuming they were using air conditioning to maintain a constant temperature.I question the validity of their testing procedure.

Without monitoring and recording air temp into each cooler at the same time as CPU temp is recorded we no accurate test being done.
So even though the 32 results were 0.25c lower than Matterhorm in this testing, this testing is not at all accurate Realistic margin of errror is +/-0.5-1c .. and that is when the delta temp is actually being done by recording air temp at the same time CPU temp is taken.
Good rule of thumb is any cooler testing being done in a case built test station is most likely not a very scientific test.![]()
I guess the real point here is an air conditioned room at 20c will not be supplying 20c air to any cooler mounted in a case. Not even at an idle, and put system under load in a case with stock case fans and it will likely be 5-10c, maybe even 20c hotter inside of case at 10-20 minutes into a full load run.I've not read any further, but I'm assuming they were using air conditioning to maintain a constant temperature.
Also, it's reasonable to test coolers with the fans that they are bundled with and in a reasonable case. Most people won't have an open air test bed that they use 24/7.
Fair points, but I think most people would assume that those factors would remain relatively constant between tests.I guess the real point here is an air conditioned room at 20c will not be supplying 20c air to any cooler mounted in a case.

Even testing on open bench test station the air temp near station will go up a degree ot two because of lighting, heat from PSU, fans, CPU, even body heat of person/s doing the testing.
I don't think that way. Always monitor air temp as close to cooler as I can and at same time as CPU temp. Year and years and years of testing have proven time and again that room temp, temp near case and temp of air going into cooler are not constant and deinitley not the same. The only way to know what the air temp into cooler mounted in a case built system is with a remote sensor monitoring temp about an inch in front of middle of front fan and looking at both air and CPU temp at same time to determine CPU delta temp.Fair points, but I think most people would assume that those factors would remain relatively constant between tests.
Have to admire your need to control all the variables.I don't think that way. Always monitor air temp as close to cooler as I can and at same time as CPU temp.

It's only common sense if you are recording temps in 10ths of a degree of a degree to keep air temp into coolers within the same 10ths range .. or record cooler intake air temps at same time as CPU temp is taken. Different cooler fans move different amounts of air and this also significan'ty effects the cases airflow temp into cooler. So if 'all the variables' are not controlled in cooler testing the margin of error becomes something crazy like +/-5c which is a 10c margin of error .. meaning test results from reviews like referenced above can easily be 5-10c off, basically making them worthless.Have to admire your need to control all the variables.
Feel like this is going off topic, so will agree to disagree.It's only common sense if you are recording temps in 10ths of a degree of a degree to keep air temp into coolers within the same 10ths range .. or record cooler intake air temps at same time as CPU temp is taken.

Are you overclocking the RAM? if not it might be worth removing the RAM heatsinks to give you a bit more clearance with the NH-D14
