Who actually makes the Antec Kuhlers anyway?
The Thermaltake's control software looks identical to the H20 920 ChillControl.
The pump and mounting plates look identical.
I believe this unit outperforms the 920.
Typical rad (H100) = 27mm thick. This Water2.0 is 50% thicker. 920 is double thick.
H100 & Water2.0 are 240mm (2x 120mm), while the 920 is only 120mm.
SO.. The Water2.0 is 50% larger than the 920.
I wonder what the FPI (fins per inch) is for both? I bet they are close.

I bet the fans are better, and the whole thing will be quieter.

actually, with a bigger radiator, you'll have a bigger fan, and with a bigger fan, you'll have higher noise levels.
A guess, but an educated guess.

Higher revs make more noise than diameter I reckon.

Of course, but you can easily change the fans, like I did.
With a bigger radiator, you need more air being pushed through it. At least I think.

Seems you connected the fan directly to motherboard, Pullout that plug and connect it here:

As I'm thinking of upgrading too.

Thanks plywood. TD - I just installed the version off the antec website (think it's 1.2) and it seems to be working OK (haven't checked the ramp is working yet), though I am missing the sound level. Not too bothered by that though.

A guess, but an educated guess.

Actually they both have 2 120mm fans.
The double thick H20 920 has them in push pull. They are on both sides of the 120mm face.
The Water2.0 Extreme has the 2 fans side by side on the both 120mm faces. It could hold 4 fans.

All Generalities are false.
Some coarse guidlines:

1. RPM is an important factor for fan noise, but so is the design and construction.
Rubber shock mounting reduces sympathetic vibrations in the case, rad etc...

2. Air passge restriction increases with higher FPI (Fins Per Inch).
Thicker RADS are likley to be more restictive. They may have other aerodymanic issues due to length.

3. 2 fans in Push-Pull can help with more restrictive air passages.

4. Higher static pressure fans are better for RADS.

5. The "Law of Diminshing Returns" is easily observed here.
The hotter the RAD vs. Air temperature, the easier it is to transfer heat to the cooler air.
Faster air flow stays cooler as it travels thru the RAD, which increases heat ransfer.
A. Increasing the wind can be pointless when the air stays relatively cool.
B. The RADs delta-T (temperature drop) of the tubing walls and fins can be a limiting factor.
C. Fan RPM vs. Static Pressure and air volume is likely to be a diminishing return curve.
D. More wind reduces the air exit temperature but not the intake. So, roughly only half of the RAD benefits.

Thermaltake Water2 2.0 Extreme. Full load on i7 3930k 6 core, ~ 155w, Room Temp 22c
RPM: 1600, Exit Air: 32.5c, Water: 37.5c, Sound: quiet rushing sound
RPM: 2000, Exit Air: 31.1c, Water: 36.7c, Sound: annoying low level rotational

I decided against win8 lol
But cheers for letting me know!

As for sound levels, that's to do with the fan pins - I don't have sound levels on mine either

Nice explanation +rep
post #2689 of 6068
Sorry about the pic quality - taken with a potato xD This is an antec 620 on my gpu - not a particularly wise choice. The reasons are threefold; A gpu processor is bigger than a cpu processor, no vrm cooling and if the bolts are overtightened the pcb will bend. But otherwise temps are good!

You can get heatsinks for the VRM's. Might help you get higher OC.
