Will a 480mm Monsta radiator fit in the bottom of a 900D with SP120 fans?
 
If you don't already have the radiator, I would advise against a Monsta for the bottom. It was hard enough maneuvering my 480 XT45 around to install it in the bottom of the 900D. I wouldn't want to do it with a Monsta, even if technically it might squeak by and fit. You won't see any real difference in performance with the SP120 between a Monsta and a UT60 or XT45 anyways.
 
I would advise against a monsta for anything due to the thickness. Royal pain in the ass to work with unless you have a case the size of my closet.

I love my Monsta, if I run my fans quiet, it performs like a champ. I have the 280 (140x2) but I have it mounted externally.

That said, you might want it stick with the UT60, it will still turn heads, and offers %85 the performance of the Monsta.

More like 95 - 105% of the Monsta depending upon fan speed ;)

I've only seen benchmarks where the Monstas are beating or matching any other radiator, could you please provide me with updated reviews?

Just about any review shows that thinner radiators perform better at lower fan speeds. Go look at Martin's initial reviews from like 4 years ago. At the lowest fan speed it was ST30 > XT45 > UT60. Once you started increasing fan speed then the order flipped.
 
Ill have a look, I'm surprised (considering the fin density) that thinner, more dense (and therefore more restrictive) radiators pull ahead.
 
It's because, at low air speeds, there is more time for heat to be transferred to the air (or, actually, more time for heat to be transferred from the water, to the fins, then to the air). It's like a cpu block in your water-loop, except instead of cpu->block->water, it's water->fins->air.

With a thinner radiator, at low speeds, it is able to effectively transfer heat to the air. At higher speeds you might get increased performance, but it quickly becomes saturated with air (it's getting more air than it can transfer heat to from the available fins/surface area).

With a thicker radiator, at low speeds the air quickly becomes saturated with heat, causing any further contact with that air and radiator fins to be ineffectual or even detrimental. At higher speeds, it acts similar to the slim radiator, except it can handle a greater volume of air before it can no longer supply heat to it. Because of the greater surface area, if it's designed correctly, it could significantly outperform a slim radiator at high fan speeds.

Totally logic'd my way through that one. If you want a better explanation, ask an expert on thermo/hydro-dynamics. ;)

The ST30 was only slightly denser, and thickness also contributes to restriction.

I've owned an XT 45 and my current Monsta, the fin density is practically double on the XT45. I would expect the ST 30 to be even more dense. The monsta's density is so low I can drop coins through it. This is why I always thought it would do awesome at low fan speeds.

But the description above makes a bit of sense.
 
I have my doubts about double, as approximately 8-10 to 16-20 is a rather large difference in FPI. The Black Ice GTX radiators have an FPI of 20, and they're considered high restriction radiators. Then again, I haven't owned both of those so I can't say for sure. Black Ice GTS... those are ridiculously high at 32 FPI.
 
The FPI on the monsta is about 8, the FPI on the other radiators is about 10. Not a big difference, certainly not double.
