120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

Great Glad you like the dutch candy

Yes, you win... Your fan gets cuts in the testing line...

UPDATE11-20-10
Sorry, I meant to test this one this morning, but my 6-32 screws were too short. I'll have to run down to the hardware store and get some threaded rod or longer screws. I hasn't seen the new bench just yet...

@martin:
They must of started manufacturing the batches earlier this year, I purchased my fans 2 from hondacity, and another 3 from a forum member on the H in april.

I have samples of both batches. For me the acoustic problems don't start until 1000 rpm or so, but I chucked that up to air turbulence hitting the fan motor. I wonder when the "new" batch was actually made.

I'm debating switching them for ap-14s, since I never run them about 1250.
I'm always amazed when people say they are quiet at full rpm. Makes me think that I either have bad examples, or they have full ears, or possibly they haven't mounted them on anything that has restriction.

Oh, heh, almost forgot. No sleeving on non of the fans.

I really do think the lower speed models are better if you plan to undervolt the 15. I havn't processed it yet, but I really liked what I subjectively heard when testing the AP-13.

GTs continue to impress....

Great stuff, Martin

Thanks for sponsoring, I feel much better about the 15 now that I've had a chance to try some of the new batch. That old batch 15 I had really had some harsh spikes in resonance. While I found some very minor amounts in the new batch, it was really small in comparison.

yeah

maybe someone will recognize it

I don't have a clue...

Hey Martin,
What did you think of the weight of that Pabst fan? Built like a tank isn't it?

No kidding, it is a BEAST...must weight a pound. I'll have to put it on a scale and see
