Hi all, i have installed an EK295 waterblock...

Well testing my water block now and idle temps are:

52 - 300mhz
60 -576

and under maxload ive hit 99 on GPU0 and 87 on GPU1.

this is a bit worrying, at max load my water loop is at 37 degrees after cooling through the radiator which passes into a core I7 at 3ghz then onto the graphics card. The vga copper block is so hot u cant really touch it.

When at peak temprature, closing a game and the heat rappidly drops to about 83 and then cools down over time.

maybe i need a 2nd loop which i cant provide. meh, this sucks
 
Hi,

*XSPC Delta V3 CPU Waterblock
*XSPC 200 Bay Reservoir & Pump ( im more than happy with the flow rate )
*Black Ice GT Xtreme 360

and this new EK 295 water block.

its res pump -> thermo sensor -> cpu -> gfx -> rad -> return to res pump.

At peak the thermo sensor is 37 degress (30 if no gpu) so i dont think its my cooling system.

At full pelt my fan was max 60% duty cycle at what ever temprature.

now its 100% at 98 on gpu0

this is really bad, i think i may go back to the fan.
 
I agree, this is a flow-rate problem. The water is being cooled well although 37 degrees water temperature seems a little high for that rad. I more than suspect the water is simply not flowing through the blocks fast enough to take a little bit of the temperature away very often. Instead it's spending too long in the cpu block and then entering the gpu block already hot. I bet if you moved the thermo sensor to after the cpu block you'd ind the temps were much much higher than 37degrees. In a well-pumped loop, the temps should stabilise with no more than a few degrees difference anywhere in the loop.
 
hey guys, i have just found the reason, one of the top holes has to be an inlet, and on the other side, it must be an out let.

I suddently realised this when i blew on them and noticed the chambers would just bypass each other....

it all makes sence now.

Guess it putting it back time... OMW!
 
my aqua computers block is the same but luckily , they capped the parrallel outlet, i just assembled mine then realised i forgot to put paste on the GPU's doh !

at 24oc ambient my 295 GPU1/2 is 36oc, VDDC1 is 345c, VDDC 2 36oc, VDDC 3 36oc.

CPU 34oc

thats with a 120.3 a liang ddc1 pro with xspc top pump running at 3800 rpm.
 
well that fixed it, geez, what a noob mistake, under load a quick 5 min soak its only at 42 degrees! Fantastic results, plent room for overclocking.

Full load: GPU0 = 43, GPU1 = 50, Ambient = 37, water temp = 30 degrees.

The huge rad is just sucking out the heat even with a modest pump and 2 fans on lowish

Next time ill READ the instrustions.

wow, now thats what, 3 times i have installed the block, uninstalled the block, installed the block and its 12:14am :) results!

Well spotted and so much for my reasoned advice which failed entirely to notice you were only having temperature problems with your gpu. I read GPU0 and GPU1 as CPU0 and GPU1.
