Don't know anything about the silverstones. But really, IMHO Scythe GT's are still king depending on the price you can get them for.

ok cheers

Scythe GTs? Really depends on your liking, Sanyo 9S is better for rads.
Strangely as "proper" fans i cannot find static pressure listing for some of the GTs

Plenty of data about GTs out there (mostly the AP18s though), manufacturer specs are BS anyway, no standard ,measurement procedures etc. .
What's so special about the sanyo's ? They seem to come in multiple speeds, pretty pricy and hard to find.
I recommended the GTs because they've proven themselves to be very good all-around fans for rads with an affordable price tag and are easy to find in shops. And I think they are actually (or at least a spin-off of) industrial fans as well, so the quality is definitely there.

Like I said, I think the Noctua's are a bit overpriced as well. They have some pretty neat engineering behind them, and the warranty only proves Noctua stands for their product and it will probably last a good long while as well. But IMHO, they just aren't good enough to justify their price premium. I only suggested them since he asked about the Noctua NF-P12 which is more a case fan.

Depends on the fan ( GT's don't do as well in pull apparently: http://martinsliquidlab.org/2012/01/15/radiator-shroud-testing-v2/2/ )

Pull allows easier cleaning of a radiator but I've found that most of the dust still collects on the side of the fan.

I would go with the most silent option in your layout because a good rad with good fans will give you decent enough temps so I wouldn't worry too much about the performance aspect but more about silence, ease of use (how easy it is to clean / replace fans etc.).

I don't know if you care about silence but once you've heard (or better, NOT heard) a silent rig then you'll have a hard tme going back to a hairdryer-like setup thumb.gif

Uh, on that one. Are you claiming Delta, one of the largest commercial fan manufacturer listed specs = BS?
And Nidec as well? San Ace?
They emit a lower noise pitch than Gentle Typhoons and are better CFM/dB

What the San Aces and Deltas have in common are fine and sharp tipped blades that actually prevents dust from building up on them. Not sure about GTs

Have you heard of the term "When one manufacturer gives a longer warranty it only means they aren't too sure about their product" ?

No they are not BS, they are probably correct in a certain way but different manufacturers use different techniques to measure their products. There's no industry standard. Perhaps the industrial manufacturers do use the same technique but for the consumer products it's definitely a waste of time to look at specs. And a manufacturer will probably want to look good on the box so assume manufacturer's specs are very "best-case scenario"...
That's what I meant.

No I have never heard of that term and frankly, it's nonsense IMO. So a manufacturer kind of knows he's making a crap product so he gives longer warranty so customers have a longer period of time in which the product can fail and they in turn can receive a free replacement?
There's little reason to give warranty as a manufacturer other than legislation and showing their quality is better than that of the competition.
A 6 year warranty is basically saying: We are pretty sure that this product will last you 6 years or otherwise we replace it for free (which is bad for us, since we had to produce something for 0 profit (and the costs of making it)). Not: It will probably break down after a while that's why gave it a longer warranty, because we love giving away free stuff and reducing our proft ...

Please, whoever said that deserves a good punch in the face. Maybe he forgot the /sarcasm tag or something?

Either way, it's off-topic.

The blades on the GTs are rather thick BTW. But personally, thick or thin blades, they all get dusty and I clean them way before I would actually notice dust on the tips.
And just to be clear, I don't think San Ace's, delta's etc. are bad. Not at all. But they do cost a pretty penny as well.
