I'm responsible for pulling together the new methology article... but I've been swamped with other matters. There's no way to give you a nutshell summary. Please be patient, I hope to have that piece up in a couple days.FartingBob wrote:Whats the cause of the large drop in CFM? Are the fans now tested whilst on a heatsink/case?
Yup. There will be a whole article devoted to nothing but Scythe fans. They sent us multiple fans of just about every model in their extensive lineup.dhanson865 wrote:Are slipstreams in the new 120mm article

If they work for you, then does the number of CFM's really matter?Fallsroad wrote:I'm astonished at the vast disparity in the CFM figures from the old methodology to the new.
Given I've just installed them today, I cannot answer with any sort of accuracy.NeilBlanchard wrote:

I was concerned mainly because the sudden change in data on the heels of placing the order for the fans, kind of threw me off.brucesm wrote:I am not sue why you are concerned about your purchase.
I cleaned up your lines to match the format I use, now I'll add a few more:brucesm wrote:I am not sure why you are concerned about your purchase.
I don't think the Nocturas fair badly...

Imagine fuel costs rising every year. If you pay for S&H what is the true cost/value equation of shipping a fan back for warranty replacement?lethul wrote:6 year warranty tho, almost foreverdhanson865 wrote:Just take note and buy the better fan next time (fans don't last forever).
I suppose I'm about to find out. The Noctua NF-P12 I bought with two NF-S12s is misbehaving, giving off a terrible, loud warbling noise, no matter how fast or slowly it spins.dhanson865 wrote: Imagine fuel costs rising every year.

Depending on what part of the world you are in compared to where you have to ship it to it might actually be cheaper to just buy a new fan for some people. Especially if the fan of choice is less than half the cost of the fan you bought the first time...
