Watercooling GTX295 are these temps normal?

[spajdr]

Hello guys,
I made a little watercooling inside my HAF932, at top of the case is mounted Feser Company Xchanger Double (240), on it i use 2x Noctua NF-S12B FLX 1200rpm (100.6 m3/h) (they are at bottom side so it takes hot air from radiator outside computer. Now directly below fans is Noctua U12P SE1366 (like 2-3cm from fans). Is this wrong?
Waterpump is Laing DDC-1T Pump - 12 V with

Waterblock on GPU is EK Water Blocks EK-FC295 GTX SLI.
Now temperatures are idling at 40 and 42C on GPU cores, PCB1 and 2 idling at 32 and 33C, are these temperatures OK? I used Arctic ceramique on Mems and GPU, should i use another one? Under load its mostly 44-45C on both GPUs, thats with vsync ON, OFF its 2-3C more mostly, but that i dont use.
Fittins are 1/4" (11/8mm) + Tygon R3603.

while having koolance block, reviewer got around 30C under load, which is pretty big difference, how to make my temps lower?

EDIT.: ok he is using this http://www.tweaktown.com/news/6354/koolance_erm_3k4u_water_cooled_server_chassis/index.html
But anyway, any tips how to make temps lower?

He has a coolant temperature of 16C. That means the room where his computer is must have a temperature of less than 16C. What's your room temperature?

Hey, the best thing that shows if there is something wrogn with the block or the contact is high delta T between idle and load temps.
Just see how the block is performing good as you get only 4°C.
Block is doing really good job :)

Thanks Eddy for reply :) i tried to find someone with similar watercool setup and your block just for comparison in temperatures but so far i didnt find anyone.
alacheesu : around 21-23C is the room temperature.

Not sure why you would bother, it's less than 50C under load, some users get over 50C in IDLE using the stock cooler.

I get 50c idle with my 285. I would be damn happy with those temps considering the 295 runs even hotter. Plus you don't have that noisy ass fan anymore :p:
