This test only show open test bench temps. It would function differently when enclosed in a case, because there is not air pressure when doing this.
Valid point.
Very valid point! Let's say it's enclosed in a case, assuming the intake and exhaust fans are balanced with slightly more positive pressure and the room temps are the same as in this video, would you say that cpu temps would be lower by adding a 3rd fan?
Was gonna say the same.
Man, just a week ago i saw the thermal paste video and you were only uploaded few vids, and subscribed, but now a NEW VIDEO!!!! Yesss!
Me too!
yesssss!!!
@@mr.morinonaka8657 😁
This is exactly the test I needed. Thank you bro.
This videos is actually really helpful to some people.Kudos my friend!
this test is dumb. He did not put the MB in a case, in a case it shows how much it makes a difference not on test bench.
@@ibobeko4309 joa is almost open, i plan it unto a CASE LIKE THAT, BUTI HAVE TO MAKE A CUSTOM ONE, THAT ONLY SUPPORTS 162MM D1 OVER THE MEMORY WITH STOCK FAN IS 168-170-172MM I DONT KNOW EXACTLY
wym? Its useful to everyone who is curious and has a radiator that can accept up to 3 fans.
I have the exact same D15 3 fan setup. That pull fan is making more noise without the thicker corner pads that Noctua provides. I noticed it right away when I installed the 3rd fan in a pull config. A new sound that was way more noticeable then it had been in a 2 fan push config. A little research and sure enough the intake side of the Noctua pull fan is simply too close to the heatsink and creates audible turbulence. In my U14S included hardware 4 thicker fan pads were included as the U14S is assumed people might put a pull fan on it. Noctua realized this and provided a fix to keep it quiet. Many different heatsinks require a gap from the pull fan to maintain quiet operation. The push side of a fan has the fan blades pushed back from the heatsink due to the fan motor and motor support arms. That's why fans pushing air aren't getting this same audible increase as they naturally have enough gap from the motor. I made a cheesy quick video at least showing what the pads look like but no audible noise tests, just showing what part you need.
Thx for video tho.
i dont think he installed the two fan setup properly. Look at pictures of the D15 from noctua. The correct way is to have one fan "pushing" into each radiator. That means one fan mounted as push on the RAM side of the heatsink, and one fan in the middle mounted as push to the second heatsink
@@henry3397yes push push config is how it was meant to be used. Some people either have tall ram and the fan can’t fit there due to the case width and others don’t want to cover their RGB ram lights. But like I have said pull configs are the worst fan configs due to the added noise penalty causing people to reduce fan speed more then they really would have needed to in push config.
I will have 3 triple fan setups soon as Noctua is sending me a few sets of fan clips for the D9L.
wow such a good "no bs talking straight to the facts video". youtube needs more of this.
And to think some people think Noctua are ugly.....👎 they rock. A noise comparison would have been good too. As would have being done in a case........ great video
And always 2 fans, in case one fails
Just subscribed. Great work sir
This video helped me choose the water loop route
mind blown, searched this up didn't expect to find a video on it, nice! thanks!.
in my case with 3 fans, it has dropped 5 degrees, it may be because of the pc case, which is normal size.
So I'm planning to do an all Noctua build. Goal is maximum quiet. This video helped confirm my idea of buying a D15 and using one of its' fans as a case fan instead. (Cheaper than buying a D15s and another fan for the case also.)
I don’t think Noctua fans are that quiet without the low noise adapter since my case fan is louder. But it’s very great performance
@@MirrkassipoegJust use your Fan Cobtroller
Thanks for doing this experiment so that I don't have to!
But the 2 fan setup is not the default one; looks to me like a push-pull on one tower instead of 2 push (one per tower) which is the noctua specification
Yeah that's what I see as well, looks like only one tower is being actively cooled with the two fans and the other is passively cooled which definitely isn't how it's supposed to be. Would be nice to see it done with both towers actually being actively cooled.
I’m just wondering, if you positioned the external fan at the front near the RAM instead of at the back as you have done, would there be any change in the temperature for the dual fan configuration?
Thanks 😊 for your efforts
Let's say it's enclosed in a case, assuming the intake and exhaust fans are balanced with slightly more positive pressure and the room temps are the same as what you have in this video, would you say that cpu temps would be lower by adding a 3rd fan?
1 degree per fan? Damn. I expected better.
it's not about the temp it's about the noise, 2 fans have to work less than 1 fan to cool of your cpu, garbage test
@@Prof_Bum the video point still stands for the temperature category. but yes you are right, your point is the actual point. the main purpose of multi fans is to reduce noise by making multiple fans doing lower rpms, effectively reducing noise. a single fan doing all the work will be ramped up by the cpu sensor, in my experience, usually its a difference of being able to hear the fan noise to almost not hearing it at all, about 5 to 10 db difference depending on the brands of the fans.
I only have 3 for aesthetic reasons. Black, white, black. Fits my build
he messed up the test imo, those two fans on the second fin stack are probably creating turbulence. Third test he got better results because he placed a fan in "push" in front of the first fin stack, but the second fin stack still has two fans on it, which is inefficient at best. The best setup is how Noctua does it, if you look at their pictures of the D15. Two fans, one in front of each fin stack, in a push configuration. This typically does 1-3 degree celcius than single fan setup
1 Fan : Max CPU: 84 Min CPU: 38 Room temp: 27
2 Fan : Max CPU: 84 Min CPU: 37 Room temp: 27
3 Fan : Max CPU: 83 Min CPU: 36 Room temp: 27
NOFAN: Max CPU: 75 Min CPU: 29 Room temp: -20 (mine)
😂😂😂
great video thanks
I wonder what the results would be in a case rather than open bench.
Bench is for benchmarking, meaning comparable from bench to bench comparison, it lower the external influence as long as you control your room temperature, which he did.
You get what you want to know, which configuration did cool the best.
By using a case, it would have be which configuration cool the best in that particularly case².
And then you'll have to take the number and configuration of those case fans , positive , neutral or negative pressure setup , with or without filters , etc... So open bench it is.
@@fabrb26 there is going to be far less variation between the 3 configurations on an open bench than there will be between the same 3 configurations in *any* case.
gracias por la info, ahora me ira bien con un solo ventilador
saludos!
God bless you mate !
Thx bro!
This is awesome, can tou do the same with the Deepcool AK620 ?.
Excelente
Thx, but I never thought that add a fan would much more do a dif. and even 3 of this expensive ones even dont do much :(.
Only what I would realy like to know how he would cool when in realistic scenario using at gaming, with 1,2 or 3 fans?
Decision with 2 fans were installed wrong, it supposed to have fan on the right for cold air intake, and not at the left with exhaust
Yep this guy clearly does not know what he is doing hence why he is getting 84C on Cinebench R20 with a N-15
wHAT RAM HAVE YOU BEEN USING WHAT ITS EIGHT, AND WHAT IS TE OVERALL HEIGHT, WIT STOCK FAN ISTALLED OVER THE MEMORY STICKS?
The best channel
I have only one fan installed in the center, but it's a Noctua 140mm industrial 3000rpm pwm though. How to tame that bastard with a fan curve.
this pretty much applies to all tower coolers 3rd fan is for try hard oc's
Great job! The question is if its apply the same in a closed case? I guess is does since most reviews before focus on package not individuelt cores. 15 vs 15s test online. I guess in a case 2 is enoug because u already have a rear exchaust fan. Thanks for making the video. Keep up!
If the rear exhaust fan can keep up with the rpms of the cpu fan. 3 fans actually gets better temps than this video does for me. I saw a 10c dif. And if your intake fans are 120mm and the cpu fans are 140mm you will get bad temps cuz the cpu fans can’t be fed fast enough. Same rules apply to size and speed of exhaust fans. They must match or exceed the ability to move air
@@gducioevdgxyeuvddd3828 Thats total BS my 120mm fans push more air than the 140s.
you must measure the differrence on package tempratures, not the hotest core..
Nice test but it would have been better if you had set up the 2 fans to push into each fin stack, as thats how the D15 normally works. Instead you set them up as push/pull on the second radiator only, which is probably why you got not much better results than the one fan setup.
Conclusion: Use 1 fan, keep the 2nd for when the 1st bites the dust.
SO 3 FAN CAN MAYBE COOL DOWN FUURE 13900KS WITH OWERCLOCKS? OR MYBE HAVE TO BUY 3000 OR 2000 RPM 14 FANS FOR THAT? WHAT DO YOU THINK?
it is amazing,, and noise? are there any differences
Can I use my Deepcool ak620 with single fan
What if you had two fans blowing into the middle and a fan on top of the heat sink sucking air upwards.
Then it would just blow the hot hair onto the glass panel
Which processor on the motherboard?
What about spinning speed?
How about the DB levels?
and what is score?
Parece no merecer mucho la pena, pero sería interesante ver si hay diferencias en largos plazos de tiempo.
En mi caso 3 ventiladores, me ha bajado de 5 a 8 grados, puede ser por la caja de mi PC, que es de tamaño normal, y un tercer ventilador haya ayudado a sacar aire caliente. En el chasis tengo 2 ventiladores de 140 y uno trasero de 120
creo que es mejor comprar el disipador con un ventilador, y esa diferencia a comprar el de 2 ventiladores, usarle para conseguir ventiladores para el gabinete no se
comprar el disipador con un ventilador y 3 ventiladores para el gabinete, en vez de comprar el disipador con 2 ventiladores
lo vería mas factible que bajar un grado por ventilador entra en el disipador (aparte del puntazo de que baja el peso y estrés que sufre la placa madre por tremendo disipador pesado)
Una pregunta compre este disipador viene con dos disipadores pero el segundo me toca subirlo un poco para que no choque con la tarjetas de ram mi pregunta es lo dejo así o puedo colocarle solamente un ventilador
i hoped this where the result because i'm think to just add one fan. the only thing i dont like about this test is there is no case just a open bench. i think the result will be differnt if you put it inside a case
I know someone who used this setup in a closed case with proper airflow, he got mid 90s-98C in cinebench on 2 fans. These coolers are way overrated, they are garbage, they cannot keep up with the fire hot temperatures these CPUs produce, they do OK mostly for stock, non turbo settings, but even a non OC, base speed no turbo, they still run quite hot, but even at stock speeds, when running for a while on turbo, the temps will reach 88-98C even at FULL fan speed in the best case - UNLESS you are super lucky and somehow have a good CPU that can handle lower voltages, some motherboards play it safe give more voltage than needed, can probably bring temps down by 5C-10C or more, but no matter what those CPUs run fucking hot - and even much so with water cooling, not much difference, it's negligible. These CPUs are optimally cooled with freon cooling. not some air cooling or water cooling unless you wanto mid 80-100C under load. or high 70's-80's for gaming
I’m not gonna lie but this is a terrible test. The heat sink is in open space so temperature should be relatively similar. What might be a better test is in a close off case, where air flow matters. Having one or two fans might be a bigger gap in temps
Jay says open air Is the best for testing coolers. It shows what the max capabilities are for Just the cooler Itself. Not everyone uses the same case and everything changes per case. fans, RPMs, 120s vs 140s etc. Plus what GPU you have, all that matters. So each case/test will be different
kinda hard to believe 2 extra fans gets you only 1 degree, maybe 27 room temp is too much
Desting inside a case would be more useful
Those fans look oversized for your heatsink blades
It's not a good idea to measure cooling performance close to the throttling temperature of the CPU. That's why there's little difference between max temps on 1 and 2 fans. The actual difference can be observed from the temperatures on the other cores which are 1-2 degrees lower and a further 1-2 degrees on 3 fans.
Either way, the center fan is the one doing all the work. You're looking at pretty negligible gains adding fans beyond the first. Although I do wonder why people's don't just go for the NH-D15S if their RAM is too tall/case is too shallow for the second fan.
Omg its hot
...
now WTF am i going to do with this extra fan lol. doesnt fit anyways but apparently 1 fan is just as good as 2 or even 3.. nice. even better.
27°C room. are you living in the sahara?
normal temp
@@uomedievo8325 ouuffff 🥵
absolutely useless on open bench, good job
I dont believe this.. theres no way 1 fan is the same as 3
not make much sense to not do that test in a real case condition, outside a case everything it s fresh :D
The test should be realized into a case with the GPU.... This test outside is no sense...
No sense test without case
Useless to test this on open air
Liquid cooler is better
barely
Never😂😂😂 plus liquid cooling will fail to you within 2 3 to 5 years specially the aios air cooler stays with you for life ! I had 2 aios both died due to pump failure or liquid loss i had an icue from corsair 240 and an id cooling zoomflow both failed after 3 4 years id cooling 2 years icue 4...so fuck them...i went for air and i bought the Noctua NH-D15 and my life changed...from 90 100 or 80 i went to max of 60 70 in games my i5 11600k can finally breathe cold 50 60 70 air after 2 years of 80 90 100 even degrees...
Noctua for life
absolutely useless test. where are fan RPMs?
LOL guy has the 2 fan configured wrong 2 fans clipped on to the same tower DOH!!
I think that the test does not reflect the whole truth. To be truthful, you need to put everything in the case and there already, the results will be different. In my closed case, with a second fan installed at the rear, the temperature dropped by 4 degrees during idle time. At 100% CPU load, the temperature is 10 degrees lower than with one fan in front!
1.Fan others can't do business give me my right
