water cooling help

[phoenix20]

i would like to cool these parts
two XFX 9800GX2 graphics cards
an asus maximus extreme mobo including the QX9770
and 8gb CorsairTwinX XMS3 and was wondering if the MagiCool XTREME NOVA 1080 would do the job without the need of an additional Feser X-Changer 240mm

This reply was posted over at XS and quoted on overclock.net :- I think this rad is not as good as it looks unless you have a helluva pump

".........inspect it closely. It's 3x Alphacool Nexxxos Extreme 360 cores (same manufacturing company, same core, same radiator - modified endtanks)... refer to testing done on such...


Pressure Drop...
ThermoChill PA120.3 - 6%
Watercool HTFX3-x - 14%
HWLabs BlackIce GT360 - 17%
HWLabs BlackIce GT360 XFlow - 17%
HWLabs BlackIce Xtreme - 17%
HWLabs BlackIce Xtreme XFlow - 17%
Watercool HTSF - 17%
Cooltek MCR320 - 18%
NexXxos Xtreme - 23%

Now look at the endtank arrangement and how the passes work.
Pass1 runs down 10 tubes, pass2 runs back up 5 tubes, pass3 runs back down 5 tubes, pass4 runs back up 10 tubes. So it steps down from 10 tubes to 5 tubes back up to 10 tubes, with 5 cavities of pressure drop en-route in endtankage between inlet and outlet...

23% pressure drop on a regular 2 pass... suddenly gets a bit larger when you make it an off-balance 4 pass. "

See martins liquid lab review of the 480mm rad from Feser you should expect if the design is the same (would make sense) that you will get ~3/4 of the performance from the 360mm version.
