be quiet! Pure Rock 2 FX

RGB makes everything cooler, science be damned!

I'll probably stop hating on RGBLED so much once everyone stops using RGBLED to sell an inferior product for more money. I'm not against RGBLED, I'm against being ripped off.

RGB contaminates far more stuff than it should (IMO), but I've still been able to easily enough find gear that fits my needs that doesn't have any. If that changes, it's at that point I'll get real salty.

If you lived in much of Europe, you'd have been real salty for a few years now.
It's not that you can't get it, it's just frequently out of stock or a limited selection, and often marked up to the same price as the RGBLED stuff because retailers are too dumb to spot the difference.

The PR2 fan is objectively superior to the FX fan at any given RPM or noise level.

The ARGBLED ring actively harms performance by occupying space in the frame, necessitating smaller fan blades. You're literally losing some of those 120mm you're paying for and trading them for rainbow lights instead, which seems like a terrible idea for a cooler that's already at the lower end of the performance scale before compromising the fan output.

The swept area of the regular PR2 fan is 15% larger than the swept area of the FX fan because of the LED ring, but that's not even the full advantage, because not all parts of the swept area contribute equally to performance. The most useful part of the swept area (nearest the blade tips) is exactly the part that's taken away from the FX fan, neatly explaining why the PR2 fan is more than the 15% better that rotor size differences would suggest.

this is news to me. All this time I thought the 120mm reference was always based on the actual "fan" size (yep silly ole unqualified me) ... so the fan size varies in a 120mm mountable unit. I just placed both images (FX/non-FX) side by side to get a glimspe of the FX fan trim - definitely not looking good! Although not interested in buying nor any other mid-ranged cooler I am curious to see how the FX performs against the PR2... any performance comparisons?

For muffin fans, the size is measured between centers of opposing mounting holes.

you know what is inexplicably wounding, i knew this at some point. I recall pulling out a ruler to measure the distance between the holes in one of my earliest builds... i guess over time looking at spec sheets with "fan size: 120mm" got my wires in a twist.

Crap - I saw a review the other week comparing the two, can't remember where.

Essentially you're looking at a 105mm RGB fan @ 2000RPM vs a 120mm fan at 1500RPM on the exact same heatsink. It's not rocket science and they perform very similarly, but one obviously makes a lot more noise and loses in noise-normalised testing, which is all that matters.

I guess another issue is that the fatter frame on the RGB fan now blocks off a couple of vanes at the top and bottom of the heatsink, removing some of the surface area that the fan can cool entirely.

For muffin fans, the size is measured between centers of opposing mounting holes.

Your muffins have holes?

120x120x25 is always the external dimensions of the fan frame because that's the size of the bay/slot/gap it has to fit in and uses industry-standard mounting hole patterns that existed long before the first home PC (yes even the beige and wood veneer ones) ever existed.

You're entirely correct. Apologies for the misinformation, @wheresmycar .
