Rrr..those looks so attractive! Waiting for more =)

Hi smicha,

I follow your post with interest, why do you use 2 pumps?
I would like to upgrade my 4 titan system with watercooling, but I don't know what radiator to choose.
What do you think about phobya xtreme nova 1080

Do I get it with 60mm thikness or 43mm ?

thank you for your response

Reason for two pumps:
1. If one of them dies the other one keeps the system running - safety reasons.
2. Increased pressure (not speed of waterflow) - this means two pumps push water much stronger, which may be important for more extensive builds.
3. Reduced noise level - setting pumps at 25-40% reduces their vibrations and make them inaudible (especially with mod kits which I'll get for this build). One pump can handle even 4 titans but with max settings and greater noise.

Radiator for 4 titans: the 1080 is fine (for an external setup) - it has 9 cooling units. More important than radiator thickness is its surface - 2x120 will always be better than 1x120 of double thickness. For really thick radiators (alphacool monsta series) you'll need push-pull setup or high pressure fans. So it's up to you whether you'll go with silent fans but 18 of them, or 9 with stronger static pressure.

P.S. I missed somehow!!! You managed to EK blocks! =) man they look cool!
Still prefer plain black pieces but those are attractive to say the least =)

I wanted plain blacks but had no choice - last two pieces.

Thanks and do you think to watercool CPU too?
I would put in 4 fan of 180mm in place of 9*120, it seems that is more quiet

2. Increased pressure (not speed of waterflow) - this means two pumps push water much stronger, which may be important for more extensive builds.

Have you got an idea of the pressure that you have in your loop?
You don't be afraid that a pipe disconnect?

I'm looking forward to see your temperature results

180mm rads are not compatible with 900D..
You need external rads or something bigger,
like caseLabs cases..

I posted all temp results at my build log - see my signature. I set my pumps to max 40% but with 100% there is no risk to blow the loop

Temps under heavy load and 25% overclock - water 35C, gps 35-45C, cpu 45-55C. At idle - water 25C, gpus 25C, cpu 30 (at 1.3V constant 4.5ghz). Silence overall.

Sorry I don't see.
Whaou very impressive
