Decided to upgrade from the Hyper 212 to a D14 (more for looks than cooling) i was checking clearances etc and thought 3 fans would look pretty cool !

 

Has anyone tried triple fans on these or any twin tower cooler?

3 fan looks cool, doesnt help in reality.

It isn't that uncommon, you can ask Noctua to send you clips through their support/warranty. If you google looking for fan clips you should find plenty of people with more fans on their coolers. I think with the NH-D14, you'd run into issues with the clips hitting each other though. I think it was recommended to use the Megahalems clips because you could fit them into the same fan notches.

 

I do remember that if you wanted to mount some leafblower 38mm fans, Megahalems 38mm clips work on the NH-D14, if that's any help!

Cheers Slayer tyvm mate :) clips was my next question :)

 

As long as there's no negative effects i like the look.  Tho i think i'll try and get some LL140's to fit for a beefier look :)

My D15 was initially run triple fans, but the 3rd fan was mounted on the case rear vents mount inside the case, and it conflicted and pushed the rear heatsink to be tilted because the motherboard Processor location is slightly more to the left than it should be to be paired with D15 and Evolv ITX, so I have to fight with the cooler and case to insert the 3rd fan. All 3 fans are plugged onto the CPU fan header by 3 splitter PWM cable.

This setup gave 2C lower than with 2 fans in 2hr Realbench stress test, and lower the temps quicker after finished the stress test from max load temps than with 2 fans.

 

Also this setup gave me further problem, the 3rd fan nudged and tilted the cooler rear heatsink and pushed back away the case rear panel so the GPU mounts is also affected by it and resulting my GPU to not plugged in properly on the PCIe slot and made the display on the monitor is blurry.

 

Then I took off the 3rd fan and tested it with smoke, found there's like turbulence at the rear part of the case, and thick smoke covering the interior. Then I put the 3rd fan back on but outside the case with same connection as before. The results are better, no more thick smoke means that no hot air is trapped because the air is well guided to exit the case, and 2C lower in motherboard temps than with 2 fans and quicker lower temps after high load, though only 1C lower CPU temps than with 2 fan in 2hr stress test with Realbench.

 

Also if you add the 3rd fan right on the cooler, the cooler total weight will be so heavy, so why don't you mount the 3rd fan on the case rear vents but connect together with the other 2..?

what type of smoke did you use?

It was a small smoke blower turbine from my office workshop which didn't work anymore and I take it and repair it, and it works.. I use it mainly to vacuum something related to my other project.

If you plan to use 3rd fan, have some padding between it and fins. Otherwise fan is too close and won't have positive effect. On U14S (probably U12S too), Noctua provides wider pads for dual fan setup. You use thin ones intake side and thich ones exhaust side.
