120mm Fan Testing on an MCR120 Radiator Round 6

[Vampiyer]

That the Noctua doesn't make an offensive sounds is important.

I just got (3) Thermalright TY-140 fans from SVC. They all make a bit of a quiet "liquid" sputtering noise. This is much better than ticking, grinding, or whining, but it's still annoying. Fortunately, this was at the full 12V-RPM, and it's only audible up-close. There is some motor growl, but it's relatively constant, and quiet.

I hope to get them on the voltage controller later and see how they behave, but I'll be on non-stop trips through to mid-december

X-bit labs seemed to think these TY-140's were the best of the 140mm fans, but I think the AP-15 (120mm) is of a better design. It's not a huge issue to me because I wanted them as 140mm case fans for my 700D, and for that, they may outperform the 120mm AP-15 anyway.

Looking at them now... they're quite big... and they will not easily mount to either of Martin's radiators (need to use gasket tape). The airflow also isn't as strong as I expected, but it's diffused over a larger area, and the hub is quite small. It's also not as ugly as I expected... I may just paint the frame matte-black and be done. I wouldn't dare paint the blades of any fan and risk affecting performance.

Nice work again, Martin.
