is static pressure mesure bs?

the one below has almost double the static pressure

but I heard you can't compare sp ratings except within brands. I couldn't find a video form GN on this.

I also imagine if I ever needed to upgrade my cooler, that bigger 140mm fan coolers would be more price efficient. but then I saw some assassin coolers with 120m rank pretty high. so then I shouldnt invest so much in a 120mm.

any specs cant be compared because w/e on the box is made up so... good old 69 cfm... 4.20 h20...

still waiting for gn to do his testing...

140mm is comparable to 120mm because even if it has less sp it has more surface area to make up the difference.

coolers and how well they do at cooling depnds on what cpu its cooling and were the hot spots are located. a cooler center over the hot spot is best but if the hot spot in not center on the cpu then what do you do...

It's not BS,

***BUT***

You need to verify that they are measuring using the same parameters. There is no standardization of testing on PC fans which is why the numbers on the box are rather meaningless on their own.

So high end 140mm tower coolers versus 120mm tower coolers, it’s kinda the land of diminishing returns.

$40 for a peerless assassin dual 120mm tower, and it’s like 90% as good as a dual 140mm nhd15 or drp4, both of which cost more than twice and sometimes three times as much

Well, it’s otherwise absolutely true, except there is some hardware in the mainstream which you can’t cool with a peerless assassin. It’s not wanting something better than required, it’s that you require something better.
They could make a cheap dual 140mm tower, and the overall cost of production would likely keep it around the $60 mark if the metric of existing coolers is anything to go by. But then it’s competing with smaller but higher end coolers, which offer a lot better options than you could get away with using a cheap cooler in terms of acoustics and aesthetics let alone thermals.

What I’m trying to say is that I wouldn’t worry too much about the value aspects of different sizes of coolers and fans, you need to get the cooler that is suitable for your system and hardware. Anything more is for frivolous, although perfectly valid, choices related to acoustics and aesthetics.

You wouldn’t really weigh up 120mm fans and coolers against 140mm fans and coolers, they’re different products for different applications. It’s not just a ratio of “more cooler per dollar”.

Id wager that the SP could be almost double between the two fans.

The corsair one has a much higher RPM and wider fan blades to boot, also the angle of them forces air harder not faster, hence the lower CFM but higher SP than the TR one
