Alphacool just released a new waterblock and here is a first review :
Check it out !
and here´s a vendor video:
You need more rad space for this setup for silent operation. Go for 2x 480 or 1x480 + 1x360. Alphacool ST30 for example and a Laing PWM pump or the Alphacool ddc310 with Eisbecher res.
Second loop is for the optic at first glance
The res. of TT pacific is a pain in the... because it´s hard to open the res. to refill
and if you want a very long lasting res. which you can put in the dishwasher: go for aquacomputer aqualis or the brandnew watercool tube res.
The eLoops are awesome on rads, as long as you use them in push mode (for what they were made) Otherwise you have to use shrouds, to minimize the noise
and for the pwm version(s): We have a similar discussion in my home forum with the noctuas. some guys claimed to hear a typical pwm sound (humming) , others not...so..maybe test one of your favorite pwm fan for yourself and decide...
I like both brands, but i dislike the ugly color of those noctuas, except the industrials...
I got this pump and compared it to others. It´s silent and has more than enough power for every "usual" loop ! Plus it don´t gets hot because of the metal bottom and max. ~3100 rpm!
I made a sound / flowrate video
